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.

Had a feeling it would be a pain, but is it doable for an a average Joe though? And what can I upgrade once I have the thing open? It'll be a perfect time to do so. Thanks.

Like, replace those with aftermarket or OEM? And how about a big bore kit? Also, what special tools would I need?

Can install a big bore later. That does not require pulling the motor and splitting the cases. The crankshaft does. Hot Rods +3mm. Do a search on this site. You may need to notch the piston skirt for the connecting rod. Cataway has some pictures of how he notched his piston for clearance.
This is the cheapest I found the stroker crank.

Yea, you’re right. Are there any other options out there for the stroker? I don’t mind spending more for a better bottom end kit. I just don’t know which ones are good.
What do you mean about notching the piston skirt? I’ve tried looking for cataway’s thread but couldn’t find it.

Thank you M_Quick. Upon reading that thread another question came up. Would I need a fuel programmer if I install the stroker? The ATV right now is all stock except for the K&N air filter. So I don’t have an exhaust or fuel programmer or know how well to use one.
