You should get air/fuel readings with any dyno session.

Corey it wasn't a dyno session just a $25 trailer ride
at a bike rally

So went back to the track after playin with the
carb.'s some more and going up 3 teeth on the rear sprocket.

101 degree day with track temp I'd say around 140 or so
and greasy as 1/2 cooked bacon went a best pass of
12.26 at 103 with a 1.80 60 ft. blowin the tire off.

I measured the tire between the rubber bead's
and Im only gettin 3" of rubber on the ground at 20 psi.
so in go's the gpz swingarm so I can fit about a 170 tire.


Monthly bonus check come's Friday so callin Buchanan's and
ordering a 17x4 Alum. rim and spoke kit then figger out what tire to run.

Was looking at tire's and M/C super store list's
a 180/55/18 Shinko 003 stealth soft compound.

Would there be any benafit staying with an 18" rim
or stepping down to a 17" like I plan.
The 17" is for a better choice of tire's.

17" would be easier to find cheap rubber for Im guessing,you could probably pick up sticky 180 rear tires pretty easy from sportbike guys upgrading their equipment

One thing to remember about those wide ass sticky tires is theyre a lot harder on driveline parts than that little 130 youve been running,so just be ready to watch chain/sprockets and transmission a lot closer.
You might be better off running something closer to a stock/street compound on a slightly used sportbike tire till you work the bugs out of the system.
and remember if its not breaking the tire loose is going to be bogging that motor down if you launch it too hard.

Has new chain, sprocket's and rear wheel bearing's
now.

The 180 is the only 18" tire Shinko offers in a soft compound.
Think I will be going with the 17" rim simply because of the tire's
available.

I think a 180 would be over kill for my junk
some where around a 160 would work better.

Called Buchanan's today about a 17" black anodized
alum rim and stainless spoke kit.
Was gonna lace it myself but for $100 buck's and a
two week turn around I'm gonna send them my hub and have them do it.

Lacing rims is an aquired skill,problem is I dont do often enough to retain that aquired skill in my head!
yeah for $100.00 id let somebody do it also.

Got started on the new strut's and mount's
Will be using a step drill to do five stepped hole's
in them have the tab's welded then the whole mess will get polished.

Some more pic.'s

I first made the tab's with three hole's but they hung off the arm
on the outside to much.

With a 130 tire.

Cool thread!

That's simple and COOL. I've been there a bunch of times with Z1's and KZ900's
I recall you were looking for a wider rear wheel?
I might be selling this one from a 89 ZX10, 4.5" x 18" it has a used 5.5" slick on it
with a 530 size chain, 45 tooth sprocket.
This pic was from the winter time.
I am waiting on a freind of a freind to buy this roller. If not I am going to part it out.
