Is that actually a modified part or is the guy B.S.ING. I cant tell since ive never seen a stock piston in one of these motors before, so i wudnt no. But i will soon

Looks like stock parts to me, and if you've already got a 54mm bore then you're gaining ZERO.

anyways how do i adjust the cam chain slack?tension, as i can see it it getting it loose after a while.

Who sells hot cam's and big bore kits and high comp piston etc.

If possible list in places in north america, but in australia is good too.

The cam chain tensioner bolt when released will let the chain go slack for the disassembly. Just put it and the spring back in after install. The oil pump will hydraulically apply the tension again for you.

Better check what size piston pin you have cause if you got a lifan it more than likely has a 14mm pin and the add said 13mm......

Is this cam actually a performance cam?

Do I need to upgrade to stainless valves, or worry about breaking the stock ones? How about valve springs.

I also am looking for a high compression piston kit, or maybe a big bore. But im definetly not stroking it.

who has all this stuff?

prefferably in north america, but i will purchase from anywhere else.

That cam has the duration lengthened just looking at it, but the lift and overlap who knows. By eye it doesn't look too wild at all. His cams look very mild to me. Also, tell us what engine you have, can help.

 

[kart_ss]

its a lifan 125 cc motor.

 

[kart_ss]

Where can i get a high comp piston that requires no maching? I dont want the valves hitting the piston. Who sells kits in north america. With a cam, high comp piston etc.

Okay so now it turns out that i actually have a loncin.

Serial numbers 152FMI

Can someone elighten me as to what performance parts will fit this is engine. High comp piston, cams, and its a big valve head Is the majority of performance cams simply a bolt on? i. According to its desciprtion on the net it has a big valve head.
