954 to 980 project
So I've had my 2002 CBR954RR for about a year now and I start hearing some rattling coming from the front of the tank. It only happens under load and when accelerating rather hard. With 73,000 miles I figured I might need to adjust the valves. So I checked my clearance.
All in spec. (Exhaust was 0.25 to 0.27 and Intake was 0.13 to 0.15). Cam Chain Tensioner was good too (manual).
I poked around the motor and the web and I find out that it's just a noise they make. Bullsh!t.
Someone mentioned piston slap, and I thought, "oh no. Please, not that."
Yes that. Cylinder 4 was the worst with scoring that you can feel. Yes, my carpenter, callused fingers were able to feel that.
So now I am undergoing the 980 conversion. Gonna replace the 75mm pistons with 76mm. I just need to find a machinist...
