Zongshen head to lifan 1p54fmi engine

[ryan12590]

hey guy just wondering if my zongshen 125 head will fit the lifan 125 all up stud pattern and the oil holes will line up and stuff becasue i have a spare zongshen head hich i have been playing around with not quite there with the porting but i just dont want to waste all the time doing it then it not fitting?

I believe it will fit, but I believe the zonger engine will have smaller valves, rendering you with less power, even with port work....

Yeh the Lifan head is the best from what ive heard, Id stick with that or ud be downgrading

[ryan12590]

well ive got the head off and ive checked the valve sizes and there 27 23 and thats big isnt it?

[Mack]

the zonger and lifan heads are mostly the same

[ryan12590]

thanks mack i was hoping someone would say that

[Mack]

What you will have to be careful of is the cam sprocket having the correct amount of teeth.

[ryan12590]

im going to use the one off the lifan will this be fine?

[Mack]

yeah, should be good. Are the cam identical?
