ok so before i start.. this IS the motor from the 84 i was compalining about a guy i know wanting to put it in a go cart, he sold the motor and everything with a blaster.. well 3 weeks later its done and a friend of mine bought it.. yes a kxt250 in a yamaha blaster..
anyways figured since its a trike motor ill post here..
he went to ride it today with us, and i had it running, and took it for aride to see how the jetting was and it ran fine except for the chain being loose and jumping on the sproket.. so, it sat well irejetted my 250r, we went to ride and he couldnt start it, so i started it for him, running for about 5 seconds than BANG!!! it back fires!
and wont restart, thought maybe i shut the choke off to soon, so i tryed a few time.. about 10 kicks later nothing just endless kicking.... than kick again and BANG!! back fires again, sherd flywheel key is the first thing that came to mind... would that be the issue? or maybe something with the electronics???
