my friends all have stock bikes and well... i wanna do a bore but i think it might be to much, i was thinking about doing a stroker crank to just get a little more torque, but i really have my heart set on a trailbikes 143 with v2 race head.... any thoughts, will this kit take away from the fun or will it be alot more fun to ride?

A 100 dollar 88 kit from dratv.com might be fun to put together if you enjoy that kind of thing, are skilled enouugh and have the time money tools and place to do it. but a stroker is serious work! alot more than a big bore

Your stocker makes just over 5 hp. If you go with the TB 143/V2 head combo you'll more than double that power output.



Installing a crank is alot of work and there are many other things you could bolt on that will give you more power.

i am splitting my case to put in a 4th gear shift drum and output shaft, so putting the stroker crank in is not much more work at all... a 143 would be fun, but only if my friends had 143 kits i think

Go for the 4th gear, stroker crank, output shaft, and star while its open. You'll be a little faster and ready for the bbk down the road. Besides, once they see they can wax their a$$ with the 143v2 they will buy one. All my friends and I said we were going to stay stock too. That didn't last. Now i'm the first to have a 155cc, 4th gear, and clutch.

Why so much the 4th gear? Is it because of the crank?

The arms race has got so out of control it's silly. You don't need more power, make the track tighter:D


its funny you say that because the track we do most of our riding at is a momentum track, so the stockers are just as fast as the bored bikes, except for one straight away....
