Clutch

[Mightyman]

@Ricky Oh! In that case, definitely could be a notched basket as @Jens-Eskildsen mentioned... Check out the walls of the basket where the edges of the friction plates slide into. If there are notches this would explain your low rev issue.

Image taken from sv650 forum. This is what the notches will look like. I doubt it will be as severe as this picture, but the notches shouldn't be there, it should look nice and smooth.

@Mightyman but I don't understand why it only started since i put the new clutch in it never did it with the old clutch

[Mightyman]

It COULD have been triggered by you changing the gear oil.
EDIT:
Or possibly the old plates had already worn enough to somehow make the issue less prominent... Why did you change the clutch in the first place? Could you give the old bits a try just to confirm it's not the assembly that's incorrect?

[Ricky]

@Mightyman these are the old 1s I changed it because it wasn't going in gear and sometimes it would get stuck in gear so when I'd pull up it wouldn't shift up or down until i turned the engine off then it would move easy

[Mightyman]

@Ricky That's also consistent with a notched basket if I'm not mistaken.. Maybe your issue the whole time hasn't been the plates, but rather the basket. If the notches aren't too deep, try to file them down and see if it performs any better.

It not going into gear could be a variety of things. Worn selector forks, bearings, clutch assembly, clutch springs.

Sounds to me like the clutch isn't disengaging.

Again what I said earlier will tell you it is clutch disengagement problem.

Never heard of a worn basket on a dt before though. Maybe if it ran with no oil. My brother ran his dt gearbox on coolant and oil with no problems. So they are pretty well engineered.

@Calum I took it to the local bike garage he said it sounds like 1 or both of push rods and ball I've had the bike on its side trying to get them out bit they don't want to come out so I'm going to get a magnet see if that works

[Mightyman]

I replaced mine as I thought they were the cause of a problem I had. Turned out they were fine and didn't have any effect on it. But worth a try for you I suppose!

[Ricky]

@Mightyman definitely worth a try get all 3 for £20

[Mightyman]

Do you have a picture of your clutch basket handy, just to rule that out?

[Ricky]

@Mightyman i will have later when i strip it again

[Calum]

Push rods and ball bearing. Sounds far fetched to me

[Ricky]

@Calum I'm going to strip it soon get the ball and rod out to check them and do some more adjustment

[Ricky]

My ball had 2 flat sides so I've ordered a new 1

[Mightyman]

Wow, hopefully it's your fix man!

[Ricky]

Hopefully

[Calum]

NORFE used to chop up some M6 bolts and use as a bearing....

Not sayinf that's good practice but was good enough for him.

[Ricky]

@Calum I've got some old bearings I was thinking of opening them up see if any are the same size the rods are ok

[Calum]

@Ricky That doesn't look great lol.

You can get the ball bearings off eBay for next to nothing..
