Hi guys, I need some help on a Suzuki PE175. The problem is the Clutch, it had problems getting into gear. When shifting into first it would slam into gear and when I come to a stop it would drag very badly. So bad I need to keep the engine on a rev and hold the brakes. So today I did a teardown and found that on the basket was some ridges ofthe friction plates. I lightly sanded them away and I took the metal plates and sanded them with sandpaper on a glass. Put everything back together and found it no longer slams into gear, but a normal tap into gear. But it still manages to drag when coming to a stop. Not as bad as before though. And another clutch issue was on the test ride, when I come rolling to a stop with the clutch lever pulled in and I give it a rev, the engine has a extremely bad vibration. Almost as the mounts are loose. But they are all tight. Also when I ride slowly and I increase rpm and when it hits the powerband its almost as if the clutch is slipping. The revs go up but the bike doesn't speed up with it. And also when its warm and I'm at a complete stop with the clutch pulled in, I can slam the throttle wide open and it won't rev past around 3500 revs. But I guess its a jetting issue that can be attended to after the clutch is sorted. For reference the cables all have enough freeplay. And I Have tried motorcycle oil, gearbox oil and currently ATF. With all oil type changes the clutch was disassembled and all the previous oil removed. And the oil type changes have made zero difference. I hope someone could shed some light on my problem. Thanks!
