Took out the cylinder today and there was way too much metal chunks. I'm gonna have to sadly tear apart the motor once again for peace of mind...
Broken crankcase, can I fix it myself?
Broken crankcase, could I fix it myself?
Long story short, I blew my motor and now there’s a hole right where the balancer is supposed to be on the right crankcase. So, I would basically need to buy a new right side crankcase and transfer or replace everything to it and I wanna know if it's doable to do myself even though I don’t have much knowledge as to how I would do that. I have the service manual but want to know your guys’ opinion if it’s something that’s possible. Thank in advance.

Hey M_Quick, ready for that auto tune btw. Still working on the ATV but almost done. Was putting new valves and noticed my 2 intake valve guides are cracked so that sucks. Bought the valve guide driver to try see if I can take it out since I had no luck without it.
My xx is also in the hospital !
It consumed oil,
and then I made the decision.
Result
worn piston,
and also cylinder, on one side,
worn out,
not much with my fingers if I touch, but the mechanic, an expert,
assures that it is a lot !
So bigger piston,
and a cylinder lapping,
if sufficient,
or a complete recalibration,
and new chrome too.
Then 2 valves, guides, to change too

Man, I'm sorry to hear that. Don't know what's up with these ATVs killing their pistons. Hopefully you get it back up and running soon.
Been busy I'll try and dig it out soon.I'm good with 160$, it does come with everything right?

Tried to start it up today and it was really hard for it to crank. My guess is a decompressor issue. Thoughts?
I figured it out, I was off timing on the cam sprocket by 1 or 2 teeth.
Now it seems like as it warms up, it's harder for it to turn back on. Not sure if it's a valve clearance issue or what. I'm beginning to lose hope.
Checked clearance and timing again and it was all good, not sure what else to check. Could it be the stage 3 cam? Bear in mind that it is new, so I don't know. Also, if I give it throttle while cranking it, it completely bogs down and makes it even harder to start. But, as soon as I let go of the throttle, it cranks.
Don't know why I can't figure this thing out. Reassembled the top end and now it won't even start. It'll crank and then after a few seconds it'll pop and smoke comes out through the air filter. What could be causing this?
I figured it out, the woodruff key was somehow sheared off. So, basically it was off timing since TDC on the flywheel was not the same as the actual piston TDC.
