blew another f4i motor...
so i'm gonna start by saying...**** my life
fresh oil(1 gallon of 20/50), fresh filter, stuntex oil pikckup, no pipe, just straight headers.
rode 10 miles to the stunt spot just fine...busted some circles for an hour...riding back home...pop a 3rd gear wheelie for maybe 100 feet, see chp, set it down, book it....maxing out the bike in 6th gear (+8/-1 sprocket)...the the bike chugs for a 2nd, then completely loses power.
btw, i **** myself thinking the cop was gonna catch up to me but i had enough momentum to switch freeways.
anyway, i pull over, look at the motor is seized, (won't start)....then i notice a small fire under the gas tank and the flame was getting bigger....i managed to put it out by blowing on it (no homo) for like 20 seconds.
i havn't took it apart yet, but my buddy who was riding behind me said he saw what looked like something shot outta the headers and alot of sparks.
any ideas what it could be?
my ONLY possible solution so far for the cause of this is...
because i had no muffler, just straight headers, cold air went back in the motor and ****ed up the valves...does that make sense?
i'm gonna end this by saying **** my life.

#7
i discovered a large hole on top of the motor...it shot out a connecting rod. hope everything else is still okay.
#8
and if it slung a rod it prolly ruined the crank, the block, and anything else it came in contact with.
