Well here goes. 200 kilometers into a 600 kilometer ride today my bike surges for a moment at 130kmh And I chalked it up to possible bad gas did it one more time a few minutes later then it was good for another 20 minutes then it searches again and I lose all forward momentum I lose all my gears had to pull off the side of the highway and in first gear I could get it to go under its own power with grinding noise coming from under the bike so I stopped I get it towed home I go to push it into my garage and I can hear a grinding coming from under the bike in neutral clutch pull feels the same I can put it into gears with bike running but nothing happens I'm hoping it's just clutch but I'm asking the experts what should I do and how do I check
