I had a F7 in the 70's and had the good luck to have a father-in-law who was the shop foreman in a Harley/Kawasaki shop. He shimmed the barrel up 1/4" and shaved the same amount off the top ,which allowed the piston to completely clear the exhaust port. It made a noticeable difference in power.
That was my first motorcycle. I bought it from a pawn shop in 92 for $200. I just bought another one last week with 1000 original miles--in much better shape than my first one! They are amazing bikes--21.5 HP from the factory and so light! I wouldn't worry about the induction (rotary vs, piston port vs reed). Whatever the issue is, I'm sure it's traditional--spark, fuel, compression. You know you have good compression, so I'm guessing it's a fuel/spark issue. These things are CDI six-volt--pretty reliable, but some little things that could go wrong. I just saw it's been nine months since you posted the video. Did you get it sorted?
I did get it running but I ended up selling it because I didn’t have time for such a big project. But I did buy another bike that I’ll be revealing next week 😉.
Hi, just a little thought, you seemed to get a lot of smoke for a short run of the engine, in my experience you might be getting too much 2 stroke oil going into the engine, i would adjust the oil pump a little & check to make sure your spark plug is the correct one, i have had two strokes that would not run until it had a new plug then all was well for a few months then the plug would go again, a new plug and all fine again for a few months. 😲
I appreciate the ideas! The big hasn’t ran for a really long time so I think the smoke is just leftover deposits in the pipe. But I’ll definitely double check the oil system. I put a new plug in it I think it’s the correct one but not much info on the Internet so I ordered a manual. Hopefully I can get all the correct info from the manual!

arrghhh... how do you get things so cheap in the states. the way she sits as you got her.... a grand easy up here.
Man I don’t think I could pay much more for a bike like this. Can’t imagine having to pay 1g :|
@@misplacedgarage I just paid £2k for a ke125A😂
So exciting!
