Looks like good progress mate I'm off to Normandy in June if Brexit don't balls it up - I always take my dog on my travels even this year for the 75th anniversary celebrations

Hi all 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 .

I used Imageworks, good quality and service, try them

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.

@harveymg there is a slight difference in shape so I'd guess you need the 200 exhaust but may need to adapt it to fit the 125 mounts

@shaunp1912 Yes

@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.

@jamesrandall93 Sounds like a good plan, I would also check all your hoses and pipes for any splits. If there is a leak or a split hose that would most likely be the culprit???

@jamesrandall93 There a straight swap, no mods required.

Once again, many thanks

@oldman Good point. Somehow forgot the basics. To be honest I half assed the help here. Go back to basics, to run you need fuel spark and air. If you got them three something should happen.

@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

@Calum Ah. Probably building bikes out of old stock then. Not uncommon.

@Calum WR200 wheels fit and are a nice upgrade, front disc is bigger so you require the nissin caliper mind

@dtr_rider_wirral For a 10% commission I'll happily list it for ya!!! :grinning_face_with_smiling_eyes: :smiling_face_with_open_mouth_cold_sweat: :face_with_tears_of_joy: Just kidding :grinning_face_with_smiling_eyes: :grinning_face_with_smiling_eyes: :grinning_face_with_smiling_eyes: - well I would if me ole mate @Calum would let me!!!

Thanks alot guys adjusted the air screw on the carb out the choke up alittle and she started first time no problem

@paul-knight Try one of these bud; https://dt125r.co.uk/topic/562/parts-suppliers-database/7

Get hold of a genuine 3nc or 3py model code early dtr same bike, both were made by mbk in france for sale in france and Italy. Ive got a mint 91 3nc mine kicks in at 6500 then has a second hit at 10000 and bounces off 12000 all day. Flies off the clock with ease, sounds like a yz even with the standard pipe. They come up on ebay now and again, snap one up if you find one. Im keeping mine its the quickest bone stock dtr ive ever riden, also comes with decent paiolli suspension front and rear standard. I had never really rode this dtr so i rode to a small local bike show 2 Friday nights ago last one of the summer, it was then after she had warmed up i discovered this thing turn into a proper flying screamer lol.
