man, i'm not even going to back read to see if i even posted in this thread ?..lol. i read enough to make me just tell you this: pull the front cover ( drain the oil first ! ) , remove the pull starter from the back so you can get at the 17mm bolt on the pull starter cage. remove the site plug from the right hand side of engine, its a allen head plug. remove the fuel tank, heat shield , remove both valve adjustment caps to access the intake and exhaust valve rockers. if the engine is still in the frame ?, this work will be a tad longer and harder to see parts. so i am guessing engine is in frame ?. with front cover off, look at the top of the cam sprocket, above it, you will see a triangle section of the case pointing down, now look on the cam sprocket, it has a punch mark stamped near the outside of the teeth. ok, now go to the rear with a 17mm socket and ratchet, look at the pull starter cage, notice it has a line running from the front to the back towards the engine on one of the tangs ?, right behind the starter cage on the cover, there is raised triangle with a point facing the center of the cage, rotate the starter cage until the line on the tang lines up with the triangle on the engine case, it may want to flip on way or the other ?, this is normal, because you have the piston on TDC. once this is done, go to the front of the engine, and look at the cam sprocket punch mark, it should be lined right under the triangle part of the case pointing down ?, also look to see if the cam chain is stretched ?. if all this is good ?, go to the sight hole ( allen head cap hole ), with a flashlight, look inside the hole to the edge of the flywheel, you should see the letter T stamped on the flywheel right inside there ?, now make sure this letter T is lined up to the line in the threads of the hole ?, every one of these marks i am telling you is a timing mark..they ALL must line up !, if they do not ?, chances are, your cam chain has jumped a tooth ?, or stretched ?, or the keyway is sheered on the flywheel ?. if you are in the states ?, pm me, give me your cell number, i'll walk you through this..DO NOT POST YOUR CELL NUMBER OUT IN THE OPEN IN THREADS !.
