We bought a Speed with a non-running engine.
We tore it down and opened up the engine, the result:
-2 broken valves (intake)
-2 bent valves (outtake)
-bent wristpin
-slightly damaged sleeve
-really ****ed up piston
One of the valves even went straight tru the piston
My questions:
-Were can I get replacement parts ???
-And what may have caused this ???
b.t.w. we think that the crank is also kinda messed up
:eek:
Engine is *******

If the rod bearing on the crank went you would have more clearance and the rod could move further up the cylinder. This could cause it to come in contact with the valves. Multiply this by several thousand rpms, and ....... ouch.

we think thats the case, but if the crank is ***** than it won't we worth getting a new one, to much $$$$.
Than it will become a Cannondale 450SX.
oh its still definatly worth it to rebuild the motor. i have only rode my bike a few times and i love the motor not to sure on the stock reliability but im sold on the power it makes. im gonna send my motor to haydug or to atk during the off season in winter most likely just to make it more reliable

We brougt the crank to a special company,
The crank is fine, but the wristpin is *****, but they can get us a new one
We think that the previous owner had a crank with **** bearings and the piston hit the valves and that they bent. Then he/she put a new crank in it and then the bent valves started playing a role.....
But that's what we THINK at the moment.
