martinshaw94 Posted May 14, 2014 Share Posted May 14, 2014 hi all to start off with my bike is the xt version but uses the same engine in the ybr and ttr the problem with the engine is that it eats oil (a lot) iv put two bottles worth in over the last 5 weeks there are no oil leaks what so ever from the engine but black soot accumulating from the exhaust but no horrible obvious smoke coming from the exhaust just wondering if this is common with this engine or is mine starting to tell me signs that something is wrong the engine has done about 20,000 miles since iv had it don't know the exact mileage due to dash going (common on xt) many thanks for reading martin Link to comment Share on other sites More sharing options...
blackhat250 Posted May 14, 2014 Share Posted May 14, 2014 Aye martyn, does it smoke on startup. .[ arter sitting] valve stem seals will be culprit,, look for smoke on startup. and sweet smell. "not as Sweet as 2stroke tho." . Link to comment Share on other sites More sharing options...
