Gear problem......help!
« on: December 02, 2014, 09:34:58 PM »

Hello again, problem number ??
Anyway, my bike yesterday wouldn't go into 4 and 5 gears.
It goes into 1st and 2nd fine then 3rd feels like its only just gone in then it won't go into the last 2 gears. It just locks up. Also the gear lever was staying up on its own and not returning all of the time.
I did notice that the chain is very slack however. If I adjust the chain would this fix it?
Any help would be great. Thanks guys

Clutch disengaging fully?
When was the last oil change?

Make sure the chain has the correct amount of slack.

Hello, yeah the clutch seems to be disengaging fine. And there's about 8mm slack on the clutch cable. The oil (so I'm told by previous owner) was changed about a month ago. Cheers

8mm of slack? So you're pulling the cable almost 1cm before the clutch starts to disengage.

Take most of that slack up, just enough to fit a small coin in.

And I never trust what a previous owner says, change the oil and oil filter yourself.

Yeah tomorrow I'm going to take up the slack and see if that sorts it along with an oil change and adjusting the chain as it should be. Hopefully that'll be an end to it. But I've got a horrible feeling its something more serious than that. I will keep you posted though. The previous owner seems to be a complete ass.  :o

Ok today I changed the oil, adjusted the chain, adjust the clutch arm correctly and I just took it for a spin and it's still bloody doing it. However now I'm riding it, it feels like its the return spring on the gear lever not doing its job. And it's also making a noise from there like a when metal rubs on metal kind of sound. It's so annoying because I've now got the engine running sweet :(

Yeah that'd be good if someone else has had this happen. Do you know anyone on here that may know bud?
Well the previous owner gave the bike a hard life before I got it so who knows what he's done to it, poor thing :)

Can you find me an exploded diagram of the gear box?

Then I can point out what I think is going wrong.
