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 .
Getting there... slowly.
Think I'm going to be taking it all apart, more annoyances appearing. Notably one of the bolts holding the tach and headlamp mount from the top has shredded, going to be tough to get out.
Once everything I need is off, removing rust and painting will take place
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.
@jamesdowning Here's how to check if the plug sparking or not? Take it out, connect it to the HT lead and place the tip against a metal surface. Crank the bike with the kick starter and look for a spark, it will be very visible for a split second. If there's a spark then the plug is getting voltage, if there's nothing then you have an electrical problem.
@Calum there’s wasn’t any issue I started using it to see if it actually did anything problem was my bike ran faultless and the only thing I noticed was the spark plug never had carbon build up and the additives main claim was that it cleans plugs I ran 50litres worth through the engine didn’t do the valves or anything never had to touch the engine
