as some of you may know i put a 100cc bbk on my scoot 2 days ago. rode to the store yesterday and it seemed like it was running rich so i didn't take the time to do a plug chop since i needed to get to work soon. drove it 6 miles to work and got there with little problem. still wasn't running right but i figured i would solve the problem when i got home.
well about a mile into my trip home i hear a very loud screech that sounded like metal on metal. at that very moment i lost power and figured i just messed up my new cylinder and piston. perhaps i was running lean and didn't understand the signs. so mad at myself for not doing a plug chop i pushed it 5 miles home.
took a nap and then started tearing the engine apart. hoping i didn't damage it too badly and was just going to put the old piston back in so i could get to work later tonight. once i got the piston exposed i didn't notice any damage. so now i am worried i may have messed up the crankshaft. i rotate the engine and i can hear something clucking around. upon closer inspection i realize it is coming from under the cvt cover.
take the cover off and my little plastic variator fan is shredded. the nut is loose... i failed to put thread locker on the last time i had it off and obviously didn't torque to spec.
guess i am riding my bicycle to work tonight. hopefully the local shop here has one, don't want to wait for delivery.
lesson learned.

) and it is running near perfect. i can't wait until it is broke in so i can test the top speed.
