How to Do Valve Clearance & Check Timing Marks /CFMOTO /KinRoad/Dune Buggy/CN250/Honda Helix

The long awaited video that the internet searched for when they have their Honda Helix clone Chinese Scooter is finally here!

Some people attempt to do a clearance without actually touching the parts while this engine was rebuilt and you are watching how the clearance is set up for the first time. Make sure you watch it through the end because I share a secret no one else knows.

I put one of these together that has the 300 cc high compression pistons installed. I have spark fuel and air and I have compression but it will not fire. Do you think the cam position and the crank position are 180 out of phase? Great video by the way.

Hi. This video is the closest to what I have been searching for a long time. I own a Honda Reflex 250cc (Honda mf06) which has similar valves like your bike, so do I follow the same procedure to adjust valves on my Reflex? Secondly, after adjusting the intake valve, must I first rotate the cumshaft to TDC again before adjusting the exhaust valve or I can adjust the exhaust valve without re-rotatating to TDC? Thank you again.

i have a roketa the valves don’t move when the valve cover is on
i removed the valve cover the cam turns the valves move when i push the valve spring the valve moves
i think my timing is way offf

When you say so the intake then turn engine again then do exhaust do you mean turn the engine a full rotation back to top dead center?

HELLO Sir . I seriously need your assistance, this is my story I owe a Honda reflex 250cc, last 2 months I tried doing the valve clearance, I followed the instructions given. Set the the engine to TDC but whiles shifting the rocker arms I felt no resistance, I got scared knowing I've started messing things up. I started the scooter once again and kinda noticed the scooter had develop a strange sound from the muffler. It changed I begn loosing performance, fuel consumption became worse.

In November I tried the valve clearance once again and still didnt feel any resistance, I tightened the two bolts (intake and exhaust) but at this point it never fired up. So I recently pulled out the engine took the cylinder head of and noticed I had both intake and exhaust valves terribly bent. I changed them got everything back, set timing and fired it up, it fired up for some few seconds but with a strange engine noise. For the last time I tried the valve clearance but experience NO resistance in the rocker arms. I noticed the T mark and mark on the cam shaft are no more aligned. I don't know what to do now, whether to get a new cylinder head or not.. could you please help me out.?
