Depends how much access you've got. If it's possible to remove the sprocket on the cam, and pull the tensioner, you should possibly be able to retime it correctly. What is it anyway ?

And then of course, there's the possibility you've bent a valve...

As long as the timing marks are aligned on the sprocket AND chain you should get a save.

hi did you have the spacy or earlier model i just removed the alternator cover and found a piece of plastic cam chain guide. wedged behind the oil pump sprocket.

maybe that chould have affected the water pump its on the same shaft just other side of the engine.

cam chain and oil pump chain are side by side behind the flywheel .i think valves be okay i was only hand turning it oh i did wind it over with starter but it never fired .becuase timing whould been way out.

is there a fly wheell puller thats kinda universal .i cant find one on ebay and seems daft you need buy for ever model bike you have.

Well, I have five flywheel pullers. Small honda is often 20mm thread on the inside of the flywheel boss. To measure is to know what you need...
