thanks guys for the info.
im sure the 200 barrel will be fine, i just brought the engine, so have no idea yet how it performs.
i do know its a stan stevens engine [famous two stroke tunner here in the uk].
im building the bike for a friend,, it will be grafted into a 2000 shaped kx125, as soon as i can find one.
i know very little about the kdx engine but have been reading this forum like crazy for a week or more now.
is it worth sticking with this E2 90/91 engine or would it make a lot more sense to look for a newer motor.
the intention was to replace every bearing and seal on the E2 engine, and do a bottom end rebuild [probably new co-rod too],,is the motor worth the investment? or does it have inherent flaws?
another question [sorry i have loads]
i notice on this engine it only has a head bracket mount on the rear of the engine,,, which i will have to chop off then presumably weld a new one on the front.. is a later 200 head with the bracket on the front usable?
thanks in advance
