At launching as the clutch starting to be engaged it stics-loose-stics..The higher the rpm the worse the problem. I almost crashed a few times from zero till I recognized that the problem wasn't my clutch hand. Literally the only way to "launch" is from idle otherwise it does instant unwanted wheelis and the acceleration is very lumpy till the clutch engaged completely. My bike have a slipper clutch but I experienced the same or close the same (as soon as I felt that sticky-bitty symptom I'm cooled down) on a stock one. My bike runs with 7100 10w50, the stock one runs with 7100 or 300v. I searched but found nothing similar. Any ideas/solutions?
