H i there can anyone tell me the way you fit mcct as i got a set from bazza and have stripped bike down and taken of front rocker cover as i wanted to check timing on front cylinder as bike pops at front carb now and then since i did engine rebuild after acct failed. So far i have lined up ft mark on 2nd small hole on alt cover,lobes facing away from each other,fi +fe marks linning up with top of engine [writing the correct way up] but this is were i stuck the fi +fe marks are very slightly of and if i jump a tooth they are of the other way i have a bad feeling the chain has stretched after the failed acct .All i can say is the fi +fe marks line up perfect with the f mark if i jump a tooth

You will never get them to be exact through general engine wear. Check TDC using a torch & looking through the spark plug hole to get the most accurate point.

You need to take up the cam chain slack in the untensioned side, so pull the chain tight on the rearmost sprocket towards the rear, and then check again.
You should find that one tooth is nearer than any other now, and that;s the one you want.

If you're worried you could change the chains, but it's a lot of work and although they stretch a bit I've never heard of one fail.

I agree, cam timing marks slightly off is fine.

The pop (or spit back as I call it) back through the carbs into the airbox now and again is quite normal for many Firestorm owners. When mine used to do that, I found it did it more when the spark plugs were getting done.

As said if you change the chains within 1000 miles they will have stretched back to the same extent as yours are now. Therefore an expensive & pointless task.
