i've noticed the same thing here with our kitted V1 as well, its much harder to kick over when its hot and you have to get it just right or get a running start on it. usually when its warmed up she just pedals up and hits the clutch and vrooom there it goes. when its cold it usually fires on the first or 2nd kick. doesnt help that the starter clutch is weak sauce on these engines, you really have to crank down on that lever, and you cant adjust it too far because it will stay on a little all the time then. maybe theres a way to weld a little tab onto the arm to make it longer so you got more torque when you pull it? theres just soo little room between the arm and the frame though. it sucks!
speaking of our kitted V1, we're going back to a high compression (210-230 psi) 50cc setup for the rest of the summer. this fall i'll be trying to make her intake for the 19mm dellorto and get that thing working. the brass choke rod is seized into the carb body..which means i need to pull ti all apart and heat it gently to see if i can free it. if i cant...i dont know what the heck to do! anyone want to donate a 19mm carb to a chesty girl with a love of mopeds?
