gypo Posted April 8, 2006 Posted April 8, 2006 First off hello all, been viewing the forum for a while but only just got round to registering. i just bought a 03 plate dt125r, i took it out today and was lucky to get 50mph out of it! when you get to 6000rpm its missing like a pig and holding back? ive changed the plug and cleaned out the air filter. looking at all the muck that is on the end of the exhaust and that was on the old plug id say its running too rich but how do i solve this please? cheers G p.s nice forum by the way
Moderator YamaHead Posted April 8, 2006 Moderator Posted April 8, 2006 to the forum Gypo You might wanna remove that exhaust pipe & run some caustic soda through it to clean it out? It's amazing the kind of build up that can accumulate in there! Had the same prob with my little lad's PW50......once I cleaned that pipe, it ran like a champ. After you get the pipe cleaned so it can really breathe again....& it still has the same symptoms... The carb will probably be the next area of attention.
gypo Posted April 8, 2006 Author Posted April 8, 2006 ok cheers mate, ill look at doing that first. thanks G
gypo Posted April 10, 2006 Author Posted April 10, 2006 so far ive cleaned the pipe out, and cut it and removed the restricter but its still missing at 6krpm or when you twist the throttle right back but only when your riding it? its driving me nuts now, does anybody have any ideas, ive also changed the plug? cheers G
gypo Posted April 11, 2006 Author Posted April 11, 2006 All sorted noww ppl, believe it or not it was the alarm unit. this was sitting under the seat on the snorkle from the air filter and choking it. whilst looking for the fault i derestricted the bike using info from here,, dtr125.co.uk exellent place for info and they also have a few good vids. G O yeah it goes like feck now!!
