RG - Extensive clean

[Drew]

11mm is big if we are talking about a clitoris and fuck all if that what you see taking a piss.

But it is looking about right. The old rear tyre was a 150 so I should be able to insert a 160 ok.

Need funds... when you coming around again I need some cash. Need rear caliper and 520 sprockets and chain to make spacers. Oh well back to the EZ while I save some funds.
Christmas is coming soon, always a good time for a cash injection. The kids always get a few dollars sent to them in Christmas cards from the family... and they think no one remembers them haaa.

Sweet.

I'm probably just missing something simple. But I'd have thought you would space the wheel in the center first, then figure out how much to chop of the sprocket carrier.

That's how I had to do it on the bucket at least.

Hey mate,

You can do it all by measuring the original wheel and spacers then transferring it all to the new rim and subtracting and adding the values to center it. Not really even much need to put it in the swing arm. That guy on the RGV forums that put those wheels on his bike made a nice write up with all you need to know for spacers and machining!

Yep sounds perfect. One small issue the old rims are not original. They are one off 500 sets of wider rims built early for the Rg500. front 3 / 16 and rear 4.0 / 18.
But you can't get front tyres now. Gone in the inorganic today!

50mm from outside of the swingarm to rear sprocket face is my starting point.

Edit... the old front is soo wide its like thinking about fucking a fatty... you look at it and then say ... bugger what's your name. No tyre but the 91 Blade tyre fits and that not good.

A police officer stops a blonde for speeding and asks her very nicely if he could see her license. She replies in a huff, "I wish you guys would get your act together. Just yesterday you take away my license and then today you expect me to show it to you!"

Enough shit< I went for a ride... no point keeping it in the shed, leaking!!

RG400 is 525 chain

So you know what you need to do......

Hi

We can help you with these, just enter the following part numbers into the search box on our website.

Front: 385U-520-16
Rear: 199-520-42HA
Chain: 520APX-120

This Tsubaki Alpha Xring chain is in fact a road chain that works very well with 600 sports bikes on the track, if you would prefer a 1000cc Race chain you can order either the Tsubaki (520PRO-120) or the slightly cheaper Renthal version (520RR4-120)

The 2 race chains come with 120 links however the APX chain that we recommend can be supplied in any length so if you decide that for example 110 link will be plenty long enough for the range of sprockets you have then just alter the part number (520APX-110)

For additional rivet links please order RL520APX (Or RL520PRO, RL520RR4 depending on your decsision)

Hope this helps, any problems just give drop us an email

Started pricing it up...

Seems so simple but there are many things one has to think about when buying a new chain and sprockets... no not you Loser on the GN250. Those sprocket will rust away before you wear them out. The chain on a GN250 is like a set of 50yr old flaps.. You can thrash them and they will never wear out.

[Arronduke]

Some info on what sprockets to use..

I run 16-44 520 on my RGV500 Talon hardened steel on the front and Renthal alloy on the rear, that is quite low, with the tyres fitted its geared for just under 130mph @ 10500 you could easily loop it in 2nd if you were a knob, good fun at Cadwell though :spoton:



I think Sean has some 500 sprockets in stock, that's where I got mine, give him a ring.



As Jim said it is best to use the biggest front you can to spread the load over more teeth, it also gives the chain an easier life as you are turning it through a larger circumference, and then go bigger on the rear to get the gearing, of course this isn't good if your tying to save 50 grammes here and there.

Also can you believe this shit.

This is were it all started.

[QUOTEmorning all.... :breaky:





im glad i lost the damn short 1st gear by using the nova box/SC. Also far more happy with the other gears.

But..i drive with a 160/60 tire and an 15/39 chain setup.

I want a bit more pull oiff the corners so it will wheely easier on the throttle...

what set up would you guys take??



15-41 ? 15-43??

Its not really necessary for the track...this year i wont do any trackdays..

I know i need too length my chain more..that wont be a problem. Ive still got a few links left...



Ive used gearing commander and putted all the variables in. It will hit the 240 km/h with the 11500 rpm it drives now.

With 15-43 it will hit the 216 km/h so it will be fun out of corners i guess...but....i will also have that shorter 1st gear again :censored:


][/QUOTE]

and

If you view gearing changes as a percentage, 1st gear will only be shorter by the overall percentage change.

Also it is best to have odd and even numbered sprockets paired together e.g.15/40 or 16/43, to even out wear 'specially on a bike like the RG5 that is firing 2 cylinders together at evenly spaced intervals.

Jim

What the fuck?

Because the torque peaks/pulses are spread out among the number of teeth, rather than arriving on a certain area of teeth in an even cycle. Sprocket teeth are loaded together each time in a cycle equal to the common denominator, even numbers come round much more regularly the those of uneven pairings.

Thus 16/40 divisable by 4 or 8 which is not so good with 2 or 4 evenly spaced cylinders. 15/40 not quite so bad but divisable by 5. Ideally you want to avoid low value denominators, 'specially with aluminium rear sprockets and/or small fronts to spread the loading over the maximum number of teeth.

Jim

and are you serious..!

It's not so much the torque peaks - though they do have a large bearing on the wear, 2 cylinders worse than 4 etc - and how they fall on the tooth pairings, it's the regularity of the teeth pairing up that matters.
Gears suffer the same effects too.

Have a odd toothed sprocket in the set and it spreads the wear out by a factor of the number of teeth of the smaller smaller sprocket.

Examples;

15/40 gives a denominator of 2.5 (40 divided by 15 = 2.5) Smallest number divisable by 2.5 is 5. So every 5 X 40 (= 200) teeth brings the same teeth pairs together.

15/39 gives 2.6. Smallest number divisable by 2.6 is 13. 13 X 39 = 507. That's just over 2.5 times as many teeth as above.


As engines only go bang every so many degrees this also spreads out the loads, a parallel twin would wear the chain/sprockets faster than a 4 cylinder inline motor (RG5 counts as parallel twin as fires 2 cylinders together, 180° spacing).

A Vee twin complicates matters a bit, but you want to avoid teeth pairings that are close to being divisable by 360°/offset angle - something HD never seemed to worry about it seems, they will wear their sprockets lobe shaped pretty damn quickly given some of the available options.

I should mention that for race bikes all the above is irrelavent, it's drive out of corners and speed that counts, not how long your chain and sprockets last.

HTH

Jim

Ok lost about 1hr ago. Beer only allows me to remember about three sentences , add a calculation and were are down to two.

[Arronduke]

Need a fresh page here.

The only thing I got out of that was I need to think about sprocket teeth counts. I have a gearbox upgrade and a taller furst gear. So what should I use?

Remember this...

you could easily loop it in 2nd if you were a knob

this dude has 16-44 sprocket ratio. I am going with 16-42 at this stage unless I'm talked out off it.! YOU yes YOU ....................................to slow already out of it!

But remember this due is running 100-125 HP rear wheel with this sprocket setup. Me I am looking for 100+ rear wheel and this bike weights 340lbs dry or 150kg. 12kg heaver than a RGV250, about equal to the average beer gut on a RGV.

[Drew]

Fucken hell. The dude wanking about even and odd numbered sprockets is a cock. What I think he was getting at, is power pulses always going through the same spots on the tyre, and making it wear funny. I would be really impressed if the cranks and tyre were ever running that syncronised. Even if they ever were, it'd be out of whack again as soon as you changed gear.

Anyhoo. Here's how I would do it. Work out the difference in rolling radius between the tyre you used to have, and the tyre you're going to run.

Were you happy with the gearing before? If so, then it's simply a matter of getting what ever percentage slower the rear wheel is now traveling, and make your front sprocket travel that same percentage faster than it does now.

If you weren't happy with the old gearing, do the same thing anyway, but change in the direction you want the gearing to go when you order.

[ktm84mxc]

Without the use of a custom build gearbox it will always be a compromise , to stop or slow the wheelies lengthen the swing arm and add in a height adjuster while your at it dito the shock linkages etc, Start with a big block of aircraft grade alloy add a CNC miller and work away.
You could always get a Harris frame built for the RG and an XR works gear box to fit it. Add Dymag wheels, Ohlins suspension etc.

Did a bit more today... after work on a Friday, beer in hand and time slips away.... Hell... wake up dude... Im not that boring, cause right now the wife is chasing a 8yr and 10yr old boys around the house trying to get them in to bed.

Women yell, boys run, screams, yelling, death treats, "Into bed... "I DID TURN YOUR ELETRIC BLANKIT ON" loud, "YOU ARE NOT LISTEING" all bad. My head is getting very low and I sneak to the door and shut it. Done, turn up the stereo and I know nothing.

Nothing is my fault. I am innocent.



Clean it and use it, or strip it and make it mint?
Only one choice if it can be pulled apart... do so.... works on the wife





D

[Arronduke]

A good find.
Always thought the bike had a good ass.

Who the fuck would marry one with a bad ass.!!


Wifes friends ass don't seem to be any good for moving house, they seem to collapse when asked to do anything.

You have a whole bike to rebuild and you're fucking around with your seat lock!

Put the pipe next to the lighter Aaron! Haha

NR500... you get the nod.

yep - had a laugh.

"its all about the journey, the destination is predictable!."

[Arronduke]

NR500... correct forgot to add, yes I will be de-carbening ( cleaning the fuck pipes, the oil shit, cant spell the facy word) the pipes with a blow torch to clean them... wife will polish.

fact is I have run out of cash..... I walk to the bank each day... hoping, thinking about my friends, like family you are. Imagine seeing a thread like this end due to a simple thing like CASH. REACH for the phone, pledge make it happen and sleep soundly knowing GOD will acctknowledge your deed. As you get older the more you need to make an effort, reach deeper in to your wallet.

YOU my friend I respect... YOU and me a team!
