Sidecars?

[cotswold]

I reckon the humble FXR could save another class from extinction.
Clever guys could turn them into something like these ( Crazy man ? )
I would be keen if they could be easily detached and ridden solo afterwards. :laugh:

[crazy man]

l think the first pic would work well , just hit a low wish l could do more

Nice work. Put the smile back on my face watching it.

I reckon the humble FXR could save another class from extinction.
:

I reckon a gentleman's agreement about all running loncins would make building one quite attractive. It'd be alot of work to build one and not having to worry about putting 'full factory' engine work in would make it easier. I'm not talking a rule change, just an understanding between mates until the class is bigger. Just a thought.

[Henk]

Bit late for that gentlemans agreement I'm afraid. Brenton's rig runs a TF motor, Mikes old rig which should be back next month has a water cooled 100 in it and Chris Lawrence has been talking to Brenton about building him a rig to take an FXR motor. If our Luncheon ends up outgunned in the engine room and we can't make up the difference through a lack of talent and stupidity we have a back up plan.
The class does seem to be growing though, hopefully it continues to.

[crazy man]

l have molds to make fiber glass thingys for the sidecar for you knee's to go into as well as molds to make a full fairing as well if anyone needs some

[wildman]

Full fairing sounds interesting can you post some pictures:cool:

[crazy man]

Full fairing sounds interesting can you post some pictures:cool:l will post a pic of my moulds . l smashed mine up on the sidecar after fliping it around 3 times and into tires . l can't fine a pic when l had them on it .silly me

[Gazzza]

Well I have te blue rig sorted, should be a bit closer next meet. As for the new build Hoping to get the frame all but done and engine mounts finished this weekend, all going well the new rig should be a go in a couple of months. it will be set up for an FXR engine, at least the swinger won't have to push this one...

Dunno about a hobby.... but you did have a certain grace about you :rolleyes:

(And I'm jealous because Warren told me there were two rigs on the track last time out :weep:)

[Henk]

Guess i'm just defensive because Skunk keeps expecting me to have a beer too many and then break something doing stupid shit like rollerblading.

Yep we had two out there for a while, in a way I was glad when there was only one running since I was racing F4 F5 and B grade as well as the trike. Was a bit tired by the end of the day.

Depends. Did you win the last GP that was run?

[wildman]

Awsome another one going soon.You can have the no1 plate, it gives me something to aim for. Don't forget to post photos on progress. Lawrence brothers nearly have their one finished and judging by their racing yesterday it's going to be action packed class.:corn:

I know the frame and wheels they are using are the same as Henk and Rick's and Gazzza's ones. Go-kart wheels and no suspension, but the engine could be a bit of a four stroke powerhouse. :whistle:

[crazy man]

will just stick to my good old water cooled tf100. tuned for mid range power. just need to get a new conrod kit and repair front end to side car

[wildman]

Not much to do at all then. You going to come up to Auckland at all with it when it's going? Gazzza on here has a couple of tf motors he might want to part with, has just repowered his chair with a 4stroke:yawn:

[crazy man]

would like to go to ackland see how it goes l guess

[Pumba]

So are we ever going to see any pictures of this awesome rig?

[cotswold]

I do not have any engineering skills so have had to put my outfit in the hands of an expert, he has just sent the photo's through and all is needed is a lick of paint and I'll see you out there.

That's the same design as the chair we drove at HD but yours is in better condition :rolleyes:
Love the fuel tank:drool:

TF motor out of an old bucket bike i brought, motor seems to run okay been thrashing it round my church carpark for the last few months and haven't been able to kill it yet so we'll see what it goes like in sidecar next weekend. Think it's running a 125 barrel on a100 bottom end, also got all of Gazzza's old tf motors from his sidecar so have plenty of spares. Honda motor fried cdi and being a headache finding another, wanted to get the sidecar going so did a repower.

[seymour14]

They'll take off Crazyman! Got you a new seat made today, not pretty, and you may have to get arse reconstruction surgery after you sit on it, but it should see us out this coming weekend!:laugh:

[Henk]

I'm playing with the idea of using leftover bits of FXR frame to build a short bike sometime (later) in the new year. Might be a bit too short and a bit tall at the front though.

Pics of the the old girl as promised

[peril 787b]

Does anybody know what happened to my old chair? 10" front and rear wheels. Was gunmetal grey, running number 47 (about 10-12 years ago). Had a CB125T and a rectangular top mounted fuel tank, twin exhaust, enclosed front wheel.
If anyone has any old pics, I'd be rapt to see them. Only ever got 2 pis of it in the couple of years I raced (always forgot to take camera).
Is the sidecar thing happening again at Mt Welly (or anywhere close-ish) to Hamilton?
I'm seriously contemplating finishing off the new chassis I started building years ago, but only if it's worthwhile and there's gonna be reasonable fields (by that I mean 4 at least)

This video was from 1999. Taupo GP. I see us (11) and numbers 1, 47, 54, 59, 69 & 99 (may be another but not sure). Were you there in 1999? If so, you may be the 47 in this video, I hope so!!


http://youtu.be/L2qhlwSEags

[peril 787b]

Yep!!! That's me.
Clear as at the 6:05 mark. jacket over the leathers as it was bitterly cold (normal for Taupo). Stuck a valve in one piston (why it goes flat at the exit).
So it was 14 years ago...
I remember racing Steve Green's (?) hub centre worm (green/blue thing). Probably not the right name, but I remember the chair.

I forgot all about Steve Greens machine, you may not have known that he died this year, poor guy. His Motorcycle Marketplace magazine was a bit of an institution for a while there. Needed more guys like him around, real dedicated motorcyclist.

It's starting to happen again at Mt wellington, we have a couple of regular runners and a couple that are occasional depending on transport and reliability, with a couple more being built that I know of. We have had four at the track but they wouldn't all go that day.
We should be at the 4 plus regulars shortly since another chair got bought out of retirement Paeroa weekend.
I'd be keen to see you finish it. There are quite a few people standing on the sidelines waiting for the feilds to stabilise at a decent number before they commit at the moment from what I've been able to gather.

[seymour14]

Yeah, that's our thoughts on it too, once sidecars are up to decent racing numbers, we should be able to get a stable field at most events. We are watching for the numbers, and are grinning every time someone announces a new build, or bringing a bike out of retirement.

Third A-Grade race from Kaitoke is almost upon us I hope, it downloaded for three bleedin hours, I am checking it has not failed on me. Fingers crossed!

[Henk]

I know you guys weren't planning on bringing your rig to Te Puke but it would be cool if you could. One of the other Auckland rigs looks like making the trip down.

See what we can do.

[Gazzza]

Have a plan to make it to Te Puke, we just have to see if Warren can shoehorn the rig into his van.
Good news is the chair is running well, I'd bet a bit on it making a whole meet... :wacko:
I think Henk has it right on the chair front, we are really close to having decent fields running, once I get my own transport sorted I will make it to most always as well.

We'll get it in the van, i got Pumba's one in and it was a lot bigger, just need to hide the hacksaw from me. Will drop by sunday after lunch for a trial fit. Hey Brenton if it runs to well i'll have to knobble it for the Sidecar Gp in April :whistle:

Outcome of which one? next wkend or sidecar Gp? for Gp i'll be running my sidecar and even i'm not game to bet on that outcome. Does your brandy mix with coke? what am i saying everything mixes with coke:killingme Did you find out anything about sidecar from Paeroa and will we see it out racing any time soon?

[wildman]

See what we can do.

Hey and don't forget sidecar Gp if you guys don't bring yours you may end up pushing mine around the track again:brick:

[Henk]

Wildman, be aware that to take part in the GP you need a full MNZ championship licence, the $200 dollar one, a day licence won't cut it. We also need six entries for it to happen, I suspect we will be running a non GP endurance race instead through a shortage of entries.

thanks for looking after him and giving me a lovely peaceful weekend btw :)

Well good news we can get the chair into Wildmans van so unless the weather goes all perfect storm on us we will be there for the Saturday racing.

Ok who is taking a 3 wheeler to the GP ?
If we are the only ones I need to know not to pop it on the trailer because it takes up to much space

[Pumba]

Sorry Rick, as I said on my thread mine wont be up and running :weep:

[seymour14]

Sorry, but ours is a non starter to. Will be worked on in the "off" season for sure, just a bit much right at the moment.

[Henk]

No room to take ours down. Sidecar entry for the weekend is dropping all the time. Looks like a possible one or two at this stage being Gazzza and Wildman.
Not too upset myself, I'll have enough to do with F4 and F5

My original write up to the Manawatu Standard (which they butchered and cut my comments out) made a remark that the kids who run in the minimoto series would be ideal candidates for moving up to F4 and F5 as a natural progression. The sidecars that they make may even be eligible for our competition too I believe?

Having not learnt my lesson from my first attempt, have now sent my original piece to an independent newspaper in our part of the world for a second attempt. Would be ideal to boost sidecar numbers if these kids could use them in our class. There are quite a few down here.

NO !!! they look to reliable, they would clean us up. Seriously if they fit in with the rules i have no problem with it. Hey Seymour my sidecar runs under it's own power now and it can keep the chain on, just need to get the dam shifter to work properly, wont downshift past fourth.

Those little bikes probably look quicker then what they are, but maybe without a fourth or fifth gear they may stand a chance?

They are all a pack of weightless school kids though, which means they are making the most of what horsepower they have got. Can't wait till we have ourselves a decent sidecar reunion, it's the only time you can swing both ways and still keep your dignity! :laugh:

I'd be happy if we could get three or four of the local sidecars to turn up regularly to our meetings up here.

[cotswold]

Ok the donor machine is acquired, it is a stinky diesel but has CVT,fuel injection and dual brake operation from the bars so not having to worry about how to mount brake and gear pedals should make it a bit easier.

Cheers for the links, interesting reading, unfortuently no "standard" sidecar plans there. Oh well.

Did get the following from one of the documents on the site that is worth posting.


Hi Roger
I have been thinking!
Sidecar stearing angles.
Head rake angles 22 to 26 degrees
positive trail 0.5 to 0.75 of an inch (10 to 15mm). Contact patch of the wheel on the road to be behind the headstock angle line where it contacts the road.
Sidecar wheel toe in = 0
Vertical lean of the bike into the sidecar = 1 - 2 degrees

Info and diagram on trail on www.race-uscra.com/sidecar.html

Went to the website and gather that the quoted info above comes form the attached two documents that are worth a read for those that are into it.

[GSVR]

Sorry just said plans assuming something was there.

also....

"positive trail 0.5 to 0.75 of an inch (10 to 15mm)."

Dunno what positive trail is. Read the PDF too. Thought trail was trail.

Negative trail would not be trail at all.

I reacon zero trail under full suspension compression would be ideal. Eccessive trail is definately one to avoid.

[cotswold]

A bit of progress on the outfit today, the front wheel was under the chassis and was not supposed to be so the whole front end was removed. Steering stem straightened and shortened, wheel spindle straightened and reassembled.
The bike had been sat in a yard for nine months and we had no key, we took the ignition switch apart and switched it on, pressed the electric leg and off she went, sounds sweet but very quiet so will be getting a new exhaust system that weighs about 20 kg less.
The chair design was drawn up and we know how and where to attach it and we found a suitable wheel.
We are going for a world speed record in outfit building and it may even be ready for the next round, if it's not it will be delayed due to my partner in crime taking a months OE in europe.

Mount welly swings both ways but I suppose if we play away we need to put it on the left ?

[Gazzza]

Well we run on the left, good for going clockwise but its up to you really. Great to hear we will have another rig soon.

[Kickaha]

I'd put it on whatever side would see the swinger over the back of the bike for the majority of the corners rather than off the side

[nodrog]

I have an adult sized shortbike forsale if any of you guys want to stop playing with toys. Cheap too. PM me if you want details.

[Henk]

I'd stick it on the left, but only because all the other rigs are set up that way.

I am having trouble pulling more than 31 rwhp (35 ish crank) reliably from my 125cc air cooled with the 24mm carb restriction.

So 150cc 2-Stroke water cooled, unlimited carb, unrestricted after market parts and whatever fuel you can get from the pumps at the petrol station and/or Av gas.

I think I could break 40 at the rear wheel, I am all for it ...... :D

The short 1000cc bike that we borrowed off the Lawrences was about the same size as our bucket rig. Lots faster though.

Got one, just have to get it going right. An old rd250 aircooled motor in it would be cool, plenty of room to fit it, and it use to run well in my old superkart.

[cotswold]

We made some good progress on the scooter chair today, the frame is made and a ply base has been made, the wheel has had a cover made and the rig has been crash tested (snee snee) as someone took off up the drive and hit a post with the outside wheel.

[Drew]

Knowing what the front end on our full size chair was made of, I predict that the steering stem is gonna twist if not snap completely.

There's quite a lot of force going through there, that wasn't possible before the chair went on.

I'd be getting a "ring in" to test too.

FGS Tim, have you not worked out that Henk's place in the team is mechanic and CTD? he's brilliant at the crash, and he's a dummy, so the role is him down to a tee. Backup CTD is Kamil.

Might see if I can find time to come laugh on Saturday, but depends what time, as I figure I need to wash my hair or something.

[agman]

If there's anyone in the B.O.P area in want of a swinger, i'd be keen to have a crack. Young,fit and light. (Something a normal bucketeer cant say faithfully xD) I've had minimal experience. I have all the gear and I'm dead keen.

Good day watching sidecars out at Mt Welly today, five sidecars out including the new scooter rig being run by Brian and Mel, [you two provide awesome entertainment ]. The three go-kart wheeled sidecars dominated again with close competition up front and at times all three battling for the same piece of track at the same time. Brenton and Andrew finally broke the domination of Rick and Henk after a hectic final race, well done guys, and after a collapsed front wheel bearing in the second race the Lawrence s were back out in the last race for a close third behind rick and Henk. Des and his daughter were having a great dice with Brian and Mel until his engine went off song, don't despair Des the mighty two strokes will rule again soon. Rumors have it that a few more chairs are nearing completion which can only make the class more exciting.:clap::clap::clap:

At least check to see if it's fatigued, regularly. I honestly expected the bars to twist relative to the front wheel, first time out.

Hmm, Kart wheels may be the best way then. Probably. Think Frenchy was getting them for about $150 each, three of them sure aint cheap.

Have you got a scooter with a chair welded on? A guy at speedway had a 70cc and a 50cc scooter and welded a chair on the side of them and held drunken races in his back yard, good fun. Lucky to hit 30km/h, but pulling wheelies and shooting off into the garden is hilarious fun.

Any of you 10" wheeled sidecars going to be down at the track this weekend?

I have a set of Hoosier LC0s that I want to get rid of. Have 4 but one has some sidewall damage so you can have that for free. Ha.
They even have some tread left.

[Pumba]

Yes please, but wont be at the track. You could deposit them in Henks van for me to pick up at a later date though.

Henk - that way we can trade, your engine for my tyres.

But you really want to be designing with the Hoosier RB25 10x7.5 in mind. Good carcass for high load and still a nice sticky compound. Best run on an 8" wide rim. Something off of an ATV works nicely.

[Gazzza]

Good to hear you are still with us Carl, if I can help in any way to get you back on the track let me know. Rick/Henk, might pay to talk to Darren or Mike Green, pretty sure they tried slicks on your new hub rig and decided to go back to an old mini tire... I'm guessing you won't have that green machine at the track this weekend? Sounds like it's going to be a wet weekend, don't suppose you could throw your groover in the back of the van Henk? <_<

Highly unlikely the new rig will be done for Sunday, we have two engine mounts in but lots still to do and some still to work out how to do.

I'd love to throw the groover in for you, unfortunately it's currently in Wellington

[Gazzza]

No worries, if it rains it rains, just hope we can stay on the track for more than a couple of laps.

To be honest I still think our kart tired rigs will totally bury that old hub rig (Henk and Ricks, not Cullys) sure it was good in its day but that was soooooo long ago I doubt anyone can even remember when it was last on the track, still if we run a handicap season we can always give you two a half lap head start...

[Henk]

Talk it up Brenton :)

See you Sunday.

[Gazzza]

Arhhhhh well let's see... Lap record last meet, hmmmmmm that would be number 35, actually according to mylaps the fastest lap in both races and prelim was errrrrrr number 35...

[Gazzza]

Breaking down and running sidecars go hand in hand, mind you apart from a thrown chain we have been pretty lucky for quite some time. I did do a bit of welding this week to stiffen up the front end, that seems to be a weak spot on the go kart framed rigs, but the Loncin's are hanging in there.

Why chromo? Your chassis should be nowhere near yield stress if you are working to a stiffness target. And chromo is no stiffer than mild.

I know Scott did some calcs for the proposed IMD250 (SteveB) version2. And the difference between mild and CrMo was about a poo (all be it a big poo)...
Thus extrapolating the calculation outcome for a sidecar, if you both have a poo then mild steel will be fine....
Better off saving weight elsewhere:
Axles and mountings. Covers. Fuel tanks. Radiators, lines, blabla...

To make it light of course.

Light comes at the design stage. If you're looking at using tube that small, I'd suspect a space frame may be in mind. If so, using straight tube, no advantage in CrMo - and major cost disadvantages. At best, using under 1 in OD, you could go down 2 gauges in wall thickness, which as quoted elsewhere may just add up to one good manly crap....

If on the other hand you look at copying Kart type construction using tube around 1.25in, then CrMo and TIG starts to look like the way to go. CrMo is pretty commonly available in that sort of size too. Just ask a Speedway car builder for some.

i was involved on the edges of Bill Newton's "gantry style" frame - a friend of mine built it. Harder than a monocoque to get right - and as it turned out, very hard to alter once it was realised where it was wrong....And I'd think, size for size, not a lot of difference in weights either. They look lighter as there's a lot of air space, but....
Pick up a track ready kart and see what you think re weight. talk to someone who repairs them for material specs.

This is mostly practice...for making a full size chair. Shorty of course, since long bikes are fucken gay.

The difficult to alter part, I hadn't considered. But I sure can see why. I need to do more planning/drawing than expected.

Counselor gets paid for six sessions by the government, I've only used one. The lying will start at about the fourth I reckon.

[Moooools]

Last page of actually constructive for once talk.

Material science lesson go: (My apologies for the parts of this that you already know)

So for you materials you have two properties that you are interested in for the pretty loose design task that is bucket sidecars. These are:

1. Yield Stress
2. Young's Modulus

Yield stress is the point at which the material will fail if a force is applied to it. In this case failure is defined as any plastic deformation (the material does not return to its original shape).
The Young's Modulus is the 'spring rate' of the material. A higher YM means that for the same force the material will deform less.

Chromo has the same Young's modulus as mild steel and most other steels, but has a higher yield stress.

When you are designing a chassis you need to keep yourself well away from the yield stress. This is where things bend and break. and getting even 1/3 of the way to yield stress can fatigue parts under the right conditions. What you will most likely be doing is putting some steel together, having a jump on it, asking yourself if it is stiff enough and adding more members to suit. This is the equivalent to building to a stiffness target.

So the crux of it is: If you took two chassis of the same construction, except one with mild and one with chromo, they would behave exactly the same for all normal riding conditions.
If you crashed the one with chromo it would probably hold up better. However the extra attention required when welding and then normalising the chromo (as it builds up a brittle structure at the weld during welding) makes it a bit harder to get right.

Mig up some mild with a shit tone of heat and filler and you are good to go.

Now I'm worried, even with out an engine our you need to be Arnold to hold it one handed...
Still there are a lot of factors that make a quick chair. Lap times will be interesting.

[Drew]

It seems to me that the pictured chair doesn't offer a great deal of input from the swinger, with regard to weight distribution. Beware the chair that only turns one way.

I can feel you running me over already!

First outing on the hub Center rig today, doesn't like right handers at all and damn near broke me with how much work it is to swing on, don't think Rick was any better off.

Put a two stroke back in, then it'll only do three laps and you won't wear yourself out.:bleh:
Tell the whole story , you's still beat Brenton first time out on it. He tells me i'm his pitcrew and now we have to sit down and work out how to get more speed out of his one:argh:
Seriously, see if you can find a flat surface and check the straightness of the lower frame rails and i know the front cross is under tension when it shouldn't be and isn't in line. I was battling with crap engines and never got round to looking properly at the chassis apart from replacing the heim joints and repairing cracks and couldn't even be sure if the suspension settings on it were correct.

You need to be lying over Rick to weight the front end, then it "might" turn right. You wait 'till you do a 1/2 hour. It took me a few minutes before I could get out and about a week before my shoulders were good.

That is some mighty camber compliance. I can't imagine that the tyre is loving trying to produce grip at 4 degrees positive(relative to direction of lateral force, not chassis) camber. Probably contributing heavily to the turning right problem.

If they are anything like their full size cousins the swinger needs to be over the right and forward leaning on the riders back otherwise they can understeer badly

It's actually under steering at this point which I have no doubt makes it look
Like there is a tonne of camber in the angle of the photo. Whether there is or isn't camber anyway, I can't comment.

Is the brake line sitting on the front tire?

Noticed it in this photo https://www.flickr.com/photos/sonscc/15176811702/ as well

yes it is....design fault or braking aid?

If it remains a braking aid then in due course I suspect it will become a design fault.

[wildman]

so you gave up on it and sold it:brick:

Yep but have another one under construction,:facepalm: Gazza tacked together the basic frame and it's along the lines of the one i raced back in the early ninties. Won't be ready till next year though, back running a gearbox kart and a kt one with my son at moment

[Moooools]

Found a couple of hours over the weekend to work on project X.

Part1

[Moooools]

Part 2 engine stuff

[Moooools]

Part 3, front end and wheels

[Moooools]

Part 4 - steering and brakes

[Moooools]

Part 5 - floor and strengthened engine mounts

Still left to do:
-Guards around wheels/axles
-Hand holds
-Fuel system
-Dash
-Secure floor
-Exhaust
-Beat Henk and Rick

*Disclaimer: Not the world's best welder. Shit is hard.

You finally came clean about actually building one. Matt at the kart shop told me you had been spending up large there. Guess i'll have to get around to putting some pictures up of my new one. Should be going by December.

[Kickaha]

Rear axle is exacly the same as I was going to do mine, front is a lot better system than I had come up with though

That blabbermouth!
I wouldn't exactly say spending up large, most of the kart parts I have found to be reasonably cheap. Matt has been very helpful though.

Where is the drinks holder?

[Grumph]

Where is the drinks holder?

In the bloody tow car I'd hope...

Are you going to ask for a dispensation to ride it sitting feet forward ?

[Moooools]

Where is the drinks holder?

I figured I would leave it on your rig. That way you can bring me a drink when you catch up after the race.

Cool, only I'll be handing one across when we lap you 😃

[Gazzza]

Really interesting looking rig, rear end looks very similar to ours but that front, what a great idea, if it works that might be my mission to make a copy for our rig...
Just a couple of questions. I know ours weighs around 115kg fuelled up on the line, do you have any ideas how much yours comes in at? The other thing was what is the length from front axle to rear axle and from middle of the rear wheel to chair wheel?
Look forward to seeing you at the track.

Yeah I was quite happy with the way the front came together. I will definitely be making it on a jig next time as it is a little on the piss. Nothing major, just ends up being slightly harder to work with.

It is currently sitting somewhere under 60kg (A one man lift still possible, just). I am picking about 80kg sitting on the start line. Could end up being more, my spreadsheet puts it at 88 but we have saved weight in some areas.
The wheelbase (from front to rear axle centres) is 1500mm and the chair wheel is adjustable from 300mm to 600mm lead (from rear axle) in 20mm increments.

Looking forward to getting to the track. Looking like it will be the 2 hour weekend.
