NEVER_EVER_EVER put the rubber in even 2nd place! the first mod I did to my scooter was to get rid of the stock tires and put a set of michelins on it. All the mods in the world are useless if the piont where they meet the road is compromised. It is the heart of the scooter. Its how you keep it under control. IMO tires and brakes are the most important improvement you can make

I have two qmb139 motors
1 that came factory in the scooter
1 that i bought for modding
Heres where i get nervous. The original motor runs so good,37-40 on flat ground, nice mixture, starts in 1 turnover and is dependable. two times now, i have failed in getting the mods just right on the new qmb139. I always left the original alone ( just use the variator & clutch mods). This way, I always have a pristeen motor to put back in the scooter.
The last time I did it, I put the 16/50 gears in and the A9 cam.
I have a 50 mm airsal kit on the way. Since I already have everything else in the original motor, I'm thinking of just lowering the motor, replacing the jug and piston, use the stock head and re-hang the motor. This is far less work than removing and tearing down both motors to swap mods.
I'm just reluctant to mess with the perfect running one as it is my backup, however it would be just changing the cylinder. Am I being too fussy? should I just do it the easier way and save the stock jug and piston?

[replyingto=yelloscoot]yelloscoot[/replyingto]I had exactly that same problem after i de=restricted my jonway-yy50qt30 raptor. I finally drilled a 1/8" hole in the gas cap
(remove cap and inside rubber). It has never happened again.I guess the fuel tank was sufficiently vented for 30 MPH, but not more ;D

Use a manual choke of some sort maybe you can find just the right size complete with butterfly and cable. If you dont have a snorkel, make it from plastic pipe.

I drilled 5 holes in mine. You can block off any of them with duct tape, both outside and inside. You drill 3/8" holes on the underside of the cover, and yhey are not visible.

That pipe is nice! On mine, (of corse only 50cc) it's whisper quiet. you almost don't hear it at all when idling. And with the helmet, you hardly hear it at full throttle.It was even fairly quiet while I was fooling with that BBK.
