@NosmokeNopoke Use JT's webby for a guide, click on the Full gear ratio chart to determine whether you want more top end or faster acceleration and choose the sizes according to your desires;
@sward Glad your now sorted, post some pics or a vid of the bike running dude!!! :grinning_face_with_smiling_eyes: :grinning_face_with_smiling_eyes: :grinning_face_with_smiling_eyes:
@AndyJay that would give you a 12.5 weight - I'd stick with stock unless the springs are too bouncy for you and some stiffer springs if you're larger than an average rider
I have just purchased a dt125r sm 2006 looking at doing a full rebuild so any advice would be much appreciated starting with powder coating and were to get new fairing and if possible any recommendations on who can do an engine rebuild .
Clean your carb out so you've got a good base point to start from. Your idle screw should be between 1 and a half turns out and about 3 turns out when the engines hot. If it's running better at under 1 and a half turns out then you want to fit a richer pilot jet, higher than 3 turns stick a leaner in. If this is set right the bike should always require choke from cold start, which is correct procedure.
