since the ttr 90 head bolts up to the ttr 50 would the 90 big bore fit on the ttr 50?

since the stock ttr 90 cylinder and head fits on the ttr 50, wouldnt that mean that the ttr 90 big bore kit (110) would bolt up as well?

not exactly.... pretty sure rods are different lengths.

wait but the 90 head and cylinder bolts up to the 50. and the 90 big bore kit bolts up to the 90. so that would mean its possible i think.

No the wrist pins are different sizes.... a ttr90 piston will not fit on a ttr50 rod.

Just the head will bolt on... Rods are different, wrist pins do not interchange so you can't use a ttr90 bore up kit on a 50.

Well it pulls forever on top end, which thats what i like.... im a pretty aggressive rider so i like to say on the gas. I had larger valves installed also and port work... to be honest with you i never rode it with a stock ttr50 head with the 107cc takegawa kit. but its as fast or not faster than my friends kaw 110s with hyper cams, jet kit, air filter and exhaust.

Just found a used 90 head...and had the work done to it...

got a takegawa 107cc kit, i believe fasterminis.com has it.

so what size valves did u run in the ttr 90 head

doopsx3 · Dec 3, 2009

well if the head will work....can the crank interchange and then maybe you could use the jug n slug

since the ttr 90 head bolts up to the ttr 50 would the 90 big bore fit on the ttr 50?
