| Major problem with 748R
Did my sixth track day for the summer today and everything was just great hunting down those gixxers and R1.
After a while I imagined, or so I thought, that the valves were noisier than before, and then at the next session I was going down the straight at about 180-200 km/h when the engine did a "Oh I just broke down and am about to spit out parts"-sound. Then I quickly pulled the cluth and turned the engine off.
Later I started the engine again and it sounded as if it only runs on one cylinder, so I quickly turned it off again.
So, the cam belts are OK and there are no oil leakage.
Btw, it's a 2002 748R with about 4500 km on the clock.
Any ideas, things to check for? |
