Redbike Posted September 29, 2017 Share Posted September 29, 2017 Now...after a year I had a chance to replace the clutch basket. with keeping my inner parts in it. The mechanic said, it is now almost like an S4 engine, however the new basket is also a used one. He couldn't find anything else, however checked the valve system, the chain and tensioner, and cleaned the injectors too. Next he remounted my clutch basket and that rattling vibration from 4000RPM was coming again. So I might need a new basket? By the way, a second symptom, the mechanic checked the tempr. of the exhaust ports with camera during the possible root cause detection. He found the rear cylinders are running on 270C while, the front 180C. Does any of us have experience with it????? Is it normal difference? After valve clearance check and injector cleaning the tempr. difference was still there. Then he mixed the spark plugs and then the other electric components. This tempr. difference is now slightly less, but still exists.... and it is not due to the wind speed. (The coolant was changed two years ago according to the manual, the thermostat and the radiators works well. 80-95C on roads. The fan starts at 102C and cools down till 96C. Fuel consumption 5-5.5L/100km.) Link to comment Share on other sites More sharing options...
