Hi all

My ‘06 SY250 has a little clutch sticking problem at the beginning of a ride. Nothing big, but I could do without it.

Has anyone here run ATF type F in their SY250 (Yamaha engine)? Any problems? Leaks? Less or more clutch sticking?

I read someplace that Dextron ATF can cause clutch plate swelling…. but I don’t know if it is true.. anyone know?

I walk the bike about 200 yards to where I start her up and jump on. I pull the lever in and out a good few times whilst walking, and when I fire her up and jump on the clutch is fine......although I did put new oil in, about 8 hrs ago.

I got the stuff that Birketts recommended, can't remember what type, will have a look later if needed.

on my old 04 beta i used to pull the cluth lever in and tie it back with an elastic band, just after a ride. next time i came to use it it was fine from cold.

I use Silkolene Light gear oil and change it every 10 hours or so.

My clutch has always stuck after it has been stood for a while, but free's off after a few metres.

Hi - Birketts recommend Motul 5100 10W40 4T oil - Drain and add 650ml

I've got mine to do this weekend so will let you know if there's a difference.

At the mo it has PJ1 Clutch Tuner in and it's still a bit grabby

cheers

Thanks guys. The clutch on my bike is not really a problem. After a few meters the clutch brakes free, and then works very well. Just like Pete described.

I'e had my 05 since new annd I've never beenable to get more then 450 mls out/in. I've leaned the bike over, I've left it to drain, I've undone the small bolt, still only 450.

I don't know if it's me or if it's my bike but 650 would fill it way higher than the level hole.

I change the oil after approx 10 hours.
