Hi there, I am a new member and have never used a forum before. I own a 250 moto 4, has smoked since I got it. Oil consumption has increased, I removed the crank case breather pipe and have a catch can under frame at front. Smoke has not changed. also after more than 20 hrs use during lock down there is a very small amount of oil come out the breather. Compression seems very high, engine turns not too bad if stopped for up to 20 mins but much more than that it is difficult to turn engine past tdc. (poss almost hydrolocked?) if left for a couple of hours or more it then turns over easier. Also if spark plug is removed. I would have expected oil to come out when turning engine with spark plug out. I suspect oil is getting down valve guides? smoke is worst during warm up. The starter motor has not worked since before I owned it and I have modified pull start as the pressure on it was causing problems. I am about to check valve clearances this morning before I get going. I do not want to dismantle while lock down is on as I am using it daily. Any help would be greatly appreciated, Dave
