So we rebuilt my friend and my own cause we split it in middle school, 91 RM125, man this thing needed a top end ?. So we have a Yamaha demo day today at Former Gotham Mt, and have a extra rider coming not for demo day but to ride who didn’t own a bike. So we got this one ready at beginning of week knowing he’s coming. Took the bike apart changed what needed to be changed, cleaned the carb, and all we do for Our own newer two smokes. Bike kicks and goes threw the gears and all. But the little fucker won’t hold a idle, it will ride but it’s a bitch to find that idle spot. My question is will this harm the bike and what would most likely be the problem? Like is the carb vacuuming itself? Or a air leak at the clamps? How would I diagnose these problems? Mostly can I ride the bike today? Would it harm the top end much? Literally need it for the day and that’s about it will disassemble again if I really have to.
Thank you and Ride Hard, have fun!!!
