[MOTOCROSS MAVERICK]

ouch!!!!  sorry to see tha!! 

[trx#9]

BEEN THERE!!!!!!!!!

[YFZ450-Tampa]

  How did that happend 

[Exmx54]

It's still good man, I'd run it! Just bend the rod back with a mallet, smooth out the cylinder with some steel wool, then JB weld back the broken peice of the piston! Just kidding, well it's sometimes good when this happens, it's going to be way faster once its back together!

[DCR_Marcus14]

well when i took it apart it was full of sand, i should have taken a picture before i washed it, but i dont understand how all the sand got in there, cause my air boot was fine and the bike was running great that day and i was even thinking how good it was running and how well it sounded a few corners before it locked up.

[YFZ450-Tampa]

Sand ? hum, was it over heated or ran out of oil ?

[DCR_Marcus14]

it was overheating a little

[Smoknbanshee]

Wear I come from, we call that TORE UP....that is one of the worst i have seen.

[Chevy1500z71]

dang u seized that thing up prety bad

[53yfz450]

let me guess its an 04 i cant stop running into problems with mine.

[MX411]

that really sucks... i had a few problems w/ my own the other day but its nothing like that all i need is a new bumper and new front plastics me and some guy a met had a full on collision.... i feel for u dude       that sucks

[Ride1Rob]

let me guess its an 04 i cant stop running into problems with mine.

I have an 04 and my motor still runs flawless.

[raptor426]

Thats not good 

[YFZ450-Tampa]

Mine is 04 and like Rob's, mine runs great, well just fixed the trainy, but I have 2 hare scrambles seasons, plus all the riding you can image, I change the oil every 4 to 5 rides, keep the air filter clean

[53yfz450]

welll mine must be a dud. i change the oil every 2 rides. i have replaced everthing in that engine. i seized it twice, blew a hole in the head and cylinder and many other things. its been good lately **knock on wood** but maybee becuase i have replaced everthing in the engine

[WOODY_450r]

It only runs good now because you put honda red plastics on it


and that sucks about your motor man...like Exmx54 said , once you fix it, it will be twice as fast

[53yfz450]

really mine got slower. no lie

[WOODY_450r]

what

[53yfz450]

im not kidding ask the eric

[WOODY_450r]

why did it get slower .....not because of the red plastics?  becasue the rebuild of the engine??

[53yfz450]

i dont know. im going to get a hinson clutch soon.

[WOODY_450r]

ur bike is pretty slow...i beat in alan front feild and i didnt even get out of third

[Hondarider22]

the red plastics actaully added speed, you should have seen it before the new fins 

[DCR_Marcus14]

hinson clutch wont do anything, stock components work no different and are way cheaper. But my motor has ran great, i never had a valve adjustment and put a piston in like 6 months ago, but it was time for it to blow up comming up to its 3rd year on racing.
