How to check valve timin on Honda 50 70 cc motors- if your off half a tooth the cam gear is worn and needs replaced or it wont run very well. ask me how I know this. ha.. great vid alex keep em coming. many people say the cam chain is stretched and thats bullshit/ try to stretch a chain and see how much you can stretch it. nadda
- Thank you, very helpful. Brad
- Glad to hear it.
- Works like a charm now ;D thanks!
- Both valves are adjusted with the engine at TDC compression stroke.
- Id just want to ask 1 more thing. Do you have to spin the engine when adjusting the other valve or just get it top dead center and adjust both?
- Hey, don't feel bad. The important thing is you figured out the issue.
- You know.... i feel pretty idiot right now.. I went to get the right tools for the job from my friend and noticed that wow how could have i missed those marks :D Running well now, Thanks for helpful video! :)
- All the Honda's have timing marks on the original parts. Check that the cam sprocket wasn't installed backwards.
- So i have 91' honda monkey z50j and it doesnt have any of those markers so how should adjust the valves without those marks to align
- please anser my fly wheel moves when i put the t mark it cant stand in one spot... what do i do' ??
- Then there is only one way the cam sprocket can bolt to the camshaft. If the mark on the cam lines up with the mark on the head, and the mark on the flywheel lines up with the mark on the case, then the cam is timed correctly.
- I think it is a 77 or 78 Honda Z50J.
- What year, make, model is the bike you are working on?
- Is there only one way the cam can go.I went through the procedures you subscribed and my engine seems to be opposite as far as the "T" on crankshaft being free and and stay in one place on the compression stroke. Mine will not stay in one place, or under pressure at "T " on flywheel ,when valves or rockers are not moving ,which I thought should be the compression stroke. And when free at "T" on flywheel valves or rockers were moving.This seemed opposite as you described.
- It's possible that the coil is failing. I've seen ignition coils work fine until they heat up. Don't rule out a dirty carburetor. They can cause all sorts of weird issues and it's easy to clean it out just to be safe.
- Can I ask you a question? I have a st50 (1977) original Honda motorcycle (has almost an identical motor as yours). And when I take it for a trip after a while the engine stotters at high revs. And when I shift and pas neutral (semi-automatic) the engine dies. Could you point me in the right direction where I can begin my search for the problem The problem only occurs when the engine is hot actually.
- Could I ask you one thing ? My motorcycle 97cc got problem about the exhaust sound . it doesn't regular .So was that about set valve timing or another else ?
- 0.002 inches for the intake, 0.003 inches for the exhaust.
- hi this vignesh . I am struggle to find out the clearance value of intake and exhaust value for this Honda engine?
