Ok...try this one out. I start my bike to warm it up for an oil change and shut it down after a few min., then drain oil out of all 3 drains and change the filter. I then add 1L of oil and run it for a few minutes and check the oil, it was down a little so I added more(which i shouldn't have) and then run it again for a few more minutes and then shut down.....with no issue. So I load it up in the truck and haul it 1hr for a trail ride and then get on it and try to kick it and it is extreamly hard to kick(unusally so). Between me a few pals we try to kick it which is close to impossible and we try to bump start which even in 5th gear drags the tire for the most part but does roll some without starting. We drain the oil incase there was to much and remove plug and it turns over flawlessly without issue. Once the plug is back in you can basically stand on the kick start. Keep in mind it will roll over with extream effort and rolls over no problem without plug. So after that long winded story........and ideas?
