So I`ve been having some issues with the CCT of my F2, I changed a new OEM unit to the bike that failed after just 500km, I took the old one apart, cleaned it and put it back together and to the bike and it ran fine until today when it started doing intermittent rattles again here and there. I`ve managed to narrow the problem down and am about 99% sure that the cause is that there is crud inside the engine due to poor maintenance of previous owners and it keeps clogging the little vent inside the CCT open thus failing to keep oil pressure up.

The question is: If I`d put some motor flush agent inside the engine, say Fortè or such other, and run it hot without driving it, drain the oil and put new in,

A) will I get any crap outta there cause the amount of the flush will be very small or I`d have to drain the oil at least partially out

B) will I be risking the wet clutch even if I don`t pull the lever in at all cause some of the motor flush will inevitably remain in the engine no matter how thoroughly I drain it?

C) or should I be better off just buying a large can of some cheap lean oil, say, full synth 10W-30 and change that a few times over the weekend between some hard riding.

Somehow I`m really not wanting to put an APE in there, mainly cause IMO that would be going round the problem and leaving it as is might kick me in the butt later on...

 

Ite oon kyllä käyttäny stp kamaa mitä saa motonetistä ja hurjimmat on lyöneet pelkkää kerosiiniakin. Ei ainakaan ollut ihan älyttömästi mujua kun leväytin ton 954 koneen ja suodatin on aina pirun painava ton jälkeen. Eikä ole ollut kykän kanssa mitään ongelmia ainakaan tossa 954:ssa.

Sorry the finnish language but was easier for me to reply I will change it to english in a bit.

 

Kattos, härmälääsiä, miten multa on menny täysin ohi teikäläinen!

So basically it won`t destroy the clutch to do it? Hmm, gotta go to motonet this week...
