adjusting the valves on the cfmoto 244cc and linhai is possible too. this way just watch the rockers level on the cfmoto then turn engine 1/2 to full turn to adjust.
i did a "yarddogs way" of adjusting the valves on my cfmoto 244cc engine it has 6300 miles now since april 11 08.
dont worry about messing anything up you cant as long as adjuster bolts dont fall out you will be ok.
unlocked the adjuster bolts, the adjusters suddenly went where they wanted to. one was level one turned sideways.
took off the cvt cover so i could turn engine. got a short breaker bar to turn engine counter clockwise, with a 18mm socket on the variator.(this is the direction the engine normally turns)
looking at the intake adjuster i turned engine and watched it .
it suddenly went to the left drastically (up on cam lobe) and i kept turning engine, then it leveled off like normal (off of cam lobe), i then turned engine 1/2 to full turn and stopped.
pushed valve adjuster toward the outboard of engine (left) then back one notch. worked like a gravy sandwich. locked the bolt.
went to the exhaust valve, the adjuster was swung to the right drastically already (on cam lobe), kept turning the engine then the adjuster swung to the level (off cam lobe), then turned the engine 1/2 to full turn. then pushed the adjuster to the right then back one notch. locked bolt. worked perfect.
engine started purred and i now have 200 miles on adjustment.
try it it is as easy as pie.
linhai can do also just watch rockers when turning engine, when follower drops off of cam lobe and near level, turn 1/2 to full turn on the crank, adjust valve. repeat onthe other valve, turn engine and when rocker is level and not on cam lobe turn 1/2 to one turn to adjust. .004-.005in intake and exhaust.
easy, no need to locate tdc. just off of cam lobe is what you are doing and near 1 full turn of crank.
the 1/2 to full turn of crank, puts the cam lobe approximately 90 to 180 degrees away from follower. and where we want adjustment performed.
(1/2 turn on crank puts 1/4 turn on cam)
hope this makes it easier for you, this way tdc is not necessary.
took all of 15-20 minutes.
do this with cold engine.
idles so good.
so easy.
this is not an original way, but the way i do it.
i corrected this post due to the correction of alauda,
1/4crank turn=1/8cam turn. 1/2crank turn=1/4 cam turn.
i thank them, they can read.
i tried to get across that when the crank turns 1 full turn, the cam turns 1/2 turn and did not present the info that way.
thank you alauda
