A budy of mine endoed his f4i last night doing a stoppie. it was perfectly upside down for 2 minutes or so. (resting on the handlebars and seat)

now it wont start. the fuel pump primes, so i don't think it is the tip over switch, or BAS. we tried to start it, won't turn over. tried push starting it, locked the wheel in every gear.

the compression is super high, like 300!!

any ideas?

 

got spark?

 

not sure. any other ideas? i'm lost on this one.

battery power wont turn it over due to the super high compression. so i can't test the spark.

 

how did you manage to test the compression if you cant turn over the motor?

 

^^^ Ya???

 

starter won't turn it over. had to turn it over by hand. (rotate the crank with a big breaker bar)

 

Do you have the tip sensor jumped? If so make sure it is still jumped

 

Oil in the cylinders?

 

it was oil in the cylinders. took forever to ge tit out.

smokes like a freight train now. i'm sure it will 4 a while!

 

that's true balling.. now when you stunt, you can try to do smoke clouds or write your name out with your exhaust smoke muhaha.. i hope it is a stunter and not a daily rider..
