I rejetted my wife's Buddy 125 and it has been running like a 50cc scoot since. It starts and runs OK but struggles to reach only 35mph. My wife is not happy because she is a WFO rider.
-It was running great before I installed a number ninety-five main jet. I have been running that same jet in my Buddy 125 so it should work well.
-After discovering that the engine is underachieving, I dropped the float bowl and ran a wire through the jets and passages. Everything looked good but the engine is still a slow poke.
-The plastic cap cap atop the carb developed a crack. To loosen the stuck float bowl screws, I had to use an impact driver, and apparently cracked that top cap.
-I repaired the crack in the carb cap with two coats of epoxy. Looks like a good repair, but the engine is still anemic.
-I re-opened the top cap be sure the spring and diaphragm were in place. It all looked good to this layman.
-I have ordered a new cap and screws, since they waller out pretty easy.
-Somebody suggested that I try some grease on the edges of the diaphragm, to be sure that it remains seated during re-assembly. I did not have time to try the grease today. (I remember when we used to apply Vaseline to the rubber gaskets and o-rings in our Holley carbs to help them seat).
-I am open to suggestions. I do not think the CVT is limiting the speed. The engine seems to remain in the proper rev range. It seems starved for fuel when I ride it.
Thanks
