New Member Big Bore Stroker Question
Hello everyone I just joined and this is my first post. I am a huge scooter fanatic on the quest for more power :clap: The problem is I have a 1p52qmi. I know the 1p52's (125cc) and the 1p57's (150cc) are the same besides the cylinder. All the reading I've done says that the difference with the p is in the head. Well if I buy this kit, won't it work since it basically replaces everything from the bottom up?

Thanks for the reply Irish. I know a spacer would lower the compression and give me valve clearance, but I'm not sure what you men by "put me back where i am now". I'm still getting the extra displacement from the longer stroke, around 20cc's I think with the 63mm bore.

P.S 0.63mm is only 0.02480 in |
yes, you are correct
Dirtrider. Irish, where did you come up with the .63 mm number?:wtf: Kinda hit it sideways with that one. With a spacer, the compression ratio will drop, but you do still get to keep the increased displacement. without the spacer the piston is likely to hit the bottom of the head. As for working with your engine, I can't say. All these chinese manufacturers have their own designs I think. Based on the same honda design.

Yes that kit will work fine w your 1p52. Not it does not require a spacer.
