had the bike a cb250 2000 model with 30,000km for a month now. have put only 1500km on it. an hour ago i was at my local carpark practicing u-turns and slow turns etc and now the bike won't work!! 1. engine still works 2. in first gear the bike will move to about 2rpm and any higher and there's no power. 2nd 3rd etc gears do not work at all. motor runs but there's no power, its like i'm holding the clutch in even though its fully out. 3. i thought it was the clutch not fully disengaging so was playing around with that and no help. i totally disengaged clutch from engine and it runs like the clutch is still in 4. with the engine off i can still roll the bike around in 1st gear. only has minor resistance. 5. bike will go max 10km/h in first gear, if i give more gas engine revs but no power. i fear i may have damaged the gears/clutch somehow. i checked oil and its still good what i was doing at the time was leaving clutch at 50/50, with throttle giving 3-4rpm, and back break on just practicing slow speed stuff. housemate picked me up and now bike is just sitting in the carpark any suggestions as to what it may be? anybody?
