It would be nice if we could have a thread w/ all the info we can get on the Jialing motors. So, whatever good info you have post it here. I am planning on doing a build on mine and I am undecide on exactly what way I want to go w/ it. I am thinking 54mm hc piston, takegawa cam, porting, and 24mm carb. I will of course dyno after I am done and post the results here. Anyone who has done any mods on these engines please post up whatever you have and any downfalls the engine may have. This thread should only be for us who want to get the most out of our Jialing motors so all you hardcore Honda guys don't come in here filling the thread w/ a bunch of nonsense and BS.
What are the valve sizes on the GPX(Jialing) motors?
I know the bore is 52.4mm and the stroke is 57mm.
The wrist pin size is 13mm.
Anyone know the cylinder height?
It can be safely bored to 54mm to give you 131cc and you can get those pistons from Tbolt.
It comes w/ a 22mm carb.
1 down 4 up tranny and now an all up tranny is available.
5 plate primary mounted clutch. Starts in any gear.
