When I had my 1000k service done (AN650K4) the mechanic put 20/50 weight Dino oil in both the engine and trans. The manual recomends 10/40 weight. When I phoned him about it (the shop is 100km from where I live) he said it was because of all the hot weather we've been having. Since then the clutch engagement is very rough. Anyone else have this problem? Does anyone else use 20/50 Dino oil?

Geesh! What part of Canada do you live in? Must be west coast, the east ain't been hot!

Also what is Dino oil? Never heard of it, syntec or just dead dinos oil?

My other question is what is your discription of 'rough' engagement? Mine is smooth as can be. I have about 3000 kms since the end of July and have had no problems at all.

Yea, dead Dinos as apposed to crushed beans. :lol: When I start out, the clutch chatters several times before it engages. Once it's engaged it's OK but it happens every time I start out, whether the bike is cold or warmed up. What weight oil do you use?

It is NOT normal. There was one incidence of total clutch failure that I know of on a 650. Get your dealer to stop making excuses and document the problem. The shattered clutch I'm referring to was sent back to Suzuki for analysis earlier this year. It blew up just out of warranty, but the gal who owned the scooter had complained to her dealer several times and had it on record. Suzuki payed for the repair. It's not an oil thing. I have run dino oil and currently run full synthetic in mine. 10-40 weight for both. No chatter at all in 11,500 miles of riding. I've ridden in 19 degree weather and 90+ degree weather with no chatter, and clutch engagement has always been smooth.

90/50 oil is pure tranny gear oil, isn't it?

that is the weight of oil I use in the rear differential of my truck. It is a very thick/viscous gear oil.

I think Dodger needs to go back and have the dealer clean out his tranny, replace the oil, and spank themselves 20 times with a 9/16" open-ended wrench!!

:twisted:

OK. I took the 20/50 oil out and replaced it with 10/40. Problem solved,
No more chatter. It took a few miles to get the 20/50 out of the clutch but all is well now. :lol:

But that's synthetic, this was Dino oil. I don't have enough mileage on it yet to switch to synthetic.
