Will I get my 100 ready in time for Taupo?

Well I usually can't be arsed with loading pics, but they do make a thread & here are my pretty painted wheels done with rattlecan enamel. Supposed to be tough stuff. Sadly it is also the worst paint ever for picking up greasy marks so needs a kero ragging at every pitstop. this happened for the photos, but can't see me maintaining interest in doing so thereafter.

and the crankcase pic just for Husaberg. doesn't show that well, I'll have to work on some thicker stickers for the next cases.

Pipe was mostly made by Sully & a bit of the welding by Sketchy, thanks guys.

That is way too clean and pretty to be one of Dave's bikes

**F5 Dave** · 17th February 2012, 21:05

yeah a wipe with an oily rag & a flash hides a lot of sins.

Thanks my Itailian is not so good so i will need google translate....Oh i get it Pis sofi =Soft Cock well strange name for a bike? Is it a Nickname?

thanks, i was a little more interested in the reed cavity.

Against all advice about them being too small for my adult proportions i have followed your lead and purchased an NF4 as it has already been hacked about i will not feel guilty about hacking it somemore. it will be a 650km round trip to pick it up but hopefully this weekend. If i am allowed out, but special thanks to Crazyman and crazyGrandad? and his friend for arranging the delivery to the South Island.
I hope it will be ready for Greymouth?.

Can the wheels be clear coated or would that not work?

RE the offst pin problem with the MB100 to use strike KT100 pistons

Yes the best engineering solution is to build a custom pin like Mikes (Speedpro) but cha ching.
But What i did find was this on the Akunar site.
yes I know the half moon bearing have a bad rep.

But here is the twist.
I seen this on a Scooter site it seems people have been modding pins like these.
This pin is too large dia 22mm vs 20mm mb100 std dia.

Some scooter boys were having the same problem. So what they were doing is putting the pin in the lathe and using emery tape to bring down the outer Diameter that runs solely in the flywheels to suit their builds. As it is an offset design I assume the hardening in the centre is not going to be effected.but tape it up though.
They later Glass bead blast the out bits of the pin (i guess to roughen it up).Or maybe toughen?
The beauty of doing this approach is the pin is the right length of the MB100 has an offset adjustable even and it will except std style bearing as well as it is approx $26 dollars nz for the pin i see you have an lathe and i guess you have some emery tape..

Problem i have is a 24mm crank-pin bugger. Otherwise i would be trying it because i am fast approaching agreed budget limits.

Just an idea and bloody cheap too.

I got the holes in the crank welded up and then rebored in a different place to do mine, it uses a stock pin and big end bearings, everything off the shelf if it blows up

problem with the MB is going inward makes the bore for the pin eat away at the crank weakening it. maybe using 20mm pin might be ok, maybe remeasure it.

Strike pistons for S version of KT look about 6" long.

erm emery tape? I just can't see that being anywhere near accurate even if you were a total fruitcake OCDer & I'm more of a ripshit&bust when it comes to doing something like that.

I'll wax/polish the wheels, maybe the polish will make them easier to clean. But of course precludes them being painted without a strip down, but as I said, I'm not that keen on doing cosmetic stuff after first attempt.

I know it does sound odd,but it will be spinning in a lathe remember. but it is only 2mm to remove or imm radius and if a cutting or using grinding tool was used it would, i guess destroy the origional heat treatment. Like i said these guys have been doing it on the thread (admittidly on scooters) i was looking at it is saved at work i will ad the link for it. Remember how Mr Munro made his primary drive the expects said no way it worked for 30 years.

With the piston length remember the stroke is going shorter as well so the length isn't probably as much of an issue with the normal piston not the odd one Yow had.

**F5 Dave** · 18th February 2012, 18:06

Scooters probably don't do 13,000, I just think it will be bush & break.

All the Strike 'S' pistons are like Yowls, the normal KT pistons are 52mm.

Either way one of my barrels will be with CR (or was it KX)3mm over 50.5 for square setup.

**Bren_chch** · 18th February 2012, 18:15

ooo that pipe is quite different to your old one... can i borrow your old pipe!?

annnddd can u pop in to my thread and comment?

**F5 Dave** · 18th February 2012, 18:37

Actually I'm going to retest my old pipe to make sure. I gerry rigged it on the dyno but it fell apart. After that yes you can try it. I'll look in on FXR site.

**F5 Dave** · 18th February 2012, 18:45

Sorry mate, forgot logon again, have to check at work where I have it.
BTW DT200s look a lot like RZ350 barrels. Mine was good fun. can't see more than ~25hp from it in std though

**Bren_chch** · 18th February 2012, 19:24

Login: oh stink.

pipe.. awesome!!! :d

dt200lc: think i reads the dt200lc as 33hp

There has been a little interest expressed in a run of offset big end pins. It's getting tempting to check out current costs for say a run of 5. Throw in a (legal)rod kit and a bit of crank machining and it could still end up being quite expensive but you save by using cheap KT100 pistons and being able to step up in .05mm steps extending the life of each cylinder.

Wob has both in stock.
KX is single ring I have paid for but nor yet seen the CR85 +3mm one.But looking at Wobs picture and a few other is likely to be two ring.
I just assumed when you asked Mike about getting an offset pin to you would want to take advantage of the Strikes availability over sizes and cost my Wiseco prolite cr85 one was $178NZD I think the 52mm strike is about $100 or so cheaper.

What is your target bore and stroke?

Er... sounds like a 10k rpm scooter to me

What kind of pickup are you using, off the HT or LT side of the coil?

Our one clips around the LT wire to the coil and when we cant get a good trace I have seen Bucket un clip it and lay the whole pickup against the side of the coil, the radiated field gives a good signal, not sure if that will work with a HT pickup but probably worth a try.
