    I haven't done anything with the F7 my son and I saved from a scrap pile a couple of years ago. It went into storage and life happened.

    Today, we decided to pour a little premix down to spark plug hole. She fired up and ran until the gas was gone.

    Still trying to get mine running again. Diagnosed as a bad ignition coil. Found a new old stock but still no love.

    Last year I swapped out the motor on my F7 due to a bad bearing in the gear box. On the new motor the oil pump is not working, I took off the clear output line and when running no oil is coming out of the pump. I swapped the pump from the old motor which I know worked and got the same results. The part off the crank, with the slot that the pump connects to is spinning. So I'm a little perplex. No I don't want to run permix since the pump does oil the bottom end which seems to be a good thing.

    There was a complex bleeding procedure if memory serves. Also weren’t the oil pump gears plastic? Might be worth checking. Might spin free but with stripped teeth, not under load.

    That said, it’s been 20 years since I had one so I may be way off base.

    I took the end caps off the pump but really couldn't see anything. One pump I know is good.

    My Son-in-Law needed a COVID 19 project. He has a new tank and petcock on the way.

    Would be grateful for any help.

    Bought a 75 f7 last week. Would start on the first kick, but die within a few seconds until the 4th kick or so and then stay running, though idle around 3000rpm.

    While it was running I adjusted the air screw til the idle settled around 1500rpm. Let it idle like that for 5 minutes or so.

    Shut off the bike til I was able to take it out for ride. Came back a bit later and it will not start at all. So I start playing with the air screw, in, out, try to go all the way in and back out making quarter turn adjustments and kick. Nothing.

    Took out the plug, looks a bit fouled but gets spark. Any ideas?

    Probably crank seals.
