i need more pull out of my second gear. like its alright now but i have a hill section in the track and if i dont get the right speed out of the burm before it, its not all that fast up it and thats y i deff can use some more pull. i dont wanna go bbk cause i dont need it for now. btw its totally stock motor if u already didnt notice. i was thinking of regearing. do 50 sprokets fit? should i go up or down in the fornt or back or both? cause i still want to be able to have some first gear. wat about a pipe? i dont want it to be too loud cause around house use. is there any pipe that will just give me that lil but extra power that i need in the range i need it in? do u guys have any other sugestions? i have $250 that i am willing to spend. thank in advanced.

Well I would recommend the TB 88 or 108. Highly recommend the 108! Foxxr70 has a TB 108 and I do too in our XR70's. Only thing is I put the motor out of my XR50 in the 70. So the only thing different is the gears inside the motor but mine is much faster off the line and in Second.

I have been fine so far with riding in 90 degree weather for a good time and the bike has been fine no problems. And yea you would need to get a Trail Bikes 3 plate manuel clutch.

if you want a punch get a tb MANUEL CLUTCH they are like 150 bucks and it will let you slip the clutch for more power..

Is that a Latin clutch? :?
i did this on my 70 with my TB 88 BBK, I put a 45 tooth rear sprocket on the back and change the front sprocket from a 14 to a 15 depending on the track. most of u guys will probly say WTF? but it works great on my 70. I can rail corners in second gear now

I would still recomend the 108...you might not need it now but I guaruntee that within a few weeks with the 88 you will be wanting more power than the 88 can deliver.You might as well go big right off the start!Especially with your summer job you will be able to get the money quickly.You will still have money for gas too.

That is true...but I know that it won't be long after getting the 88 that he will be wanting the 108...that's my opinion anyways.

You might also want to get a new timing chain.One of my friends got a 108 and his timing chain skipped a few teeth...luckily no severe damage.So you might want to look into getting a HD timing chain.
