suzuki tm125 tm rm 125 flat tracker track mx twinshock spares or repair project

here is a suzuki tm 125 flat track bike. we have had it for some time. we have just fitted a new old stock kick start ratchet. we checked over the whole engine. the bike sounds awesome but messes around below quarter throttle. it can only be the wrong jet. the bike needs new tyres are they are split. this bike is a cheap way to enter the vintage class. i would love to keep it but im way to tall to ride it. it could probably do with some new cables but they all work ok as they are. collection is fine or you can send a courier. any questions feel free to send a message. this bike is pre rm. im sure the bike has aftermarket ignition and the piston i have never seen one like that before. but the thing sounds awesome and goes really well
