I decided to start a new thread because the previous posts on my last thread were a bit misleading-
So my bike would at first start to die when I put it in gear and would have to feather the throttle to keep it alive (would idle fine in neutral). Furthermore, I would have to rev super high to get to reasonable speeds within certain gears and the bike sounded like it was only firing half the time.
I narrowed it down to the clutch or compression issues (I changed spark plugs, cleaned carbs, tested the tuning, synced carbs, and probably more)
I rode it around despite its issues about 3 times and now it won't even idle in neutral properly. Therefore, I was wondering if somehow the clutch could affect the way the bike idles in neutral.
Furthermore, I haven't been able to test the compression when hot because of starting issues, but when testing compression cold, I got a mere 75psi, but equal on both sides. I want to say that I just had the compression gauge not as tight as I probably should have, just because I'd rather not tear the whole engine apart.
I plan on soaking the pistons in some mystery oil/acetone mix for a month
Any help or previous, similar experiences would be extremely helpful.
Thank you to the community
