A top end rebuild makes sense, but I'm on the fence because if the engine is like the rest of this bike there's at least three other things wrong with it.

Your English is fine. I'm extrapolating a bit because on a motorcycle, the transmission and the engine are one unit. I should have said transmission.

I'm comparing this one to my 77 750 that I rode in 2023 and 2024. This one I can clutchless downshift with the throttle completely closed and no clutching. I guess there's a chance the clutch is getting worn out...

As for the valves, I did those as soon as I got the bike and of course they were out but they're all back in, and choosing between shims I went with the looser of the two.

And this thing tends to be a bitch to start most of the time so yeah. You're starting to make me think I need to do a valve job. Compression is 128 to 184 PSI per the manual, with a rebuild at 100. I've got 121 to 140. And yeah, it makes dogshit power. Feels like it makes less than the 750 I had and both bikes had the exact same mods, except for filter brand. It won't even pull to the top of 4th.

Cool to see another 8, er, 4 valve in here. Never expected to.

No idea, I'm not in here that often. I'm probably in the running with my '78. But if Suzuki is so reliable how did mine spit the tachometer cable out today?
