about time someone said that. def a stock carb probably been bored out by a pro so that is whyit looks stock. you don't have any way of reaching the previouse owner to find out what has been done to it? I would't remove that base spacer. there is a reason that is there. he probably has put a stroker in it with that port job. the intake side has been opened up alot. the exhaust has probably been altered too it just has carbon build up. what kind of pipe did it have on it? if it had the stock pipe on it the last guy probably sold, or kept it. that is probably why it runs like butt. you shouldn't be running that stock jet with that porting work. sounds like this guy modded the balsty and sold off the goody's or kept them for his next blaster.
I have no way of reaching the previous owner, my kidbrother traded his beta trialbike for the Blaster with some people not from around here, and I got it from my brother in my turn.
They´ve obviously been using it for some kind of freestyleridin, on the rearframe it´s been lenghtened with steelpipes for "wheeliestanding" (sh*t that sounds weird, I just mean where U put U´r foot during wheelies..) so I´m guessing they probably only wanted the low-end effect.
Rearaxle-bearings was shot to pieces, guess that´s due to wheelieing too...
The pipe is stock, but I´m gonna put a KX125 pipe on it instead, seems impossible it would give a worse flow than with the stock one.
As far as the gasket goes, I´m going to check what happens without it first - if it don´t bang in to the head and everything seems ok - I´ll probably fire it up to see if she runs good or not.
It´s not too much work to pick the cyl off again and remount the gasket, if it runs like a pile of sh*t that is - but that´s for the future to tell!
I have to try, if it has a strokercrank it will be pretty obvius it wont work.
About the jetting, what would U recommend as a good startingpoint? 260? Theres a 340, I think it was, in my 39mm - but maybe I´ll try that restrictor-ring that was discussed earlier and smack on the 39mm instead... Don´t know yet..
Getting my piston today though, so it´s time to see if theory matches practice...
