....................so I asked the mechanic "what oil are you using?"
"er sumfin like 20/50 fully synthetic" came the reply.
So there we have the culprit.!
I did order new friction plates, clutch cover gasket, oil filters and got some real good Putoline 10/40 semi synthetic from a mate that sells the stuff. (10l for �40!) enough for more oil changes and my small CB250RS Honda!
Did the job today, easy peasy, except that the manual does not mention to take the brake pedal off (which I did), other than that it was easy. Drain all of the oil as per
.
The last friction plate as you go in has a bigger internal diameter and a disc spring sits inside of this. It is an antichatter spring and is clearly marked which way around it goes.
I assembled all of the clutch as it came out but with the new friction plates, new gasket fitted and all tightened up, refit the (now folding!) rear brake lever, then refil with oil and hey presto all good. Went for a blast through to Hull (@130 return) and all is good, no slipping and the engine 'feels' better, cannot quantify but certainly fresher.
Anyhow apart from spilling some oil onto the radiator, job done.
As I got the oil cheap I will probably do another change in a few hundred miles just to make sure all of the 'crap' is out of the system, might appear to be overkill, but lets face it an oil change is probably the cheapest yet most important maintenance that you can do to a bike.
