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.

I’m trying to install the front sprocket and I’m unsure which way it’s supposed to go. Does it go in with the flat side out or does it go in with the grooved side out? Thanks.

Flat side out.

Appreciate it like always. Thanks.
Any pointers on how to remove the front hubs? I need to replace my discs and the hubs aren't budging. Thanks.

Try some PB blaster, heat or a puller.

Alright, I'll get one of those 2 jaw pullers, spray some PB and heat it up with a heat gun. Hopefully it'll do the trick
Used a 3 jaw puller, applied lots of heat, used PB blaster, hit it way too many times with a hammer and nothing... I might have to replace the hub and knuckle. I really hope the other side isn't like this.
Do any of you guys have a map for a bored and stroked engine with barker's exhaust, K&N filter, EHS lid, and stage 3 cam?
Or at least, which base tune I should use from the dynojet website to get me by until I can get it professionally tuned?

I have a slightly used auto tune if interested.

I would be but I don't wanna deal with welding it to the exhaust and stuff. I called a local shop and they quoted my 300$ an hour which will definitely hurt. I'm thinking about using the 006 map on the dynojet site, just to break it in then take it to the shop.
Can you give me more info on the auto tune? I might be interested after all

I'd have to dig it out for pictures. I bought it used from someone else that said they never installed it. They plug into the PCv, and have to be hooked to power and ground. And like you said you have to have a bung welded into the header. $300 and hour for a tune isn't bad. They should be able to tune it within the hour, if they know what there doing with the PCv mapping.

Is the auto tune better than getting it tuned by someone or is it the same thing? And the reason is that I might hold on to my stock exhaust for a bit longer since I don't wanna spend 800$ for the barker's exhaust since I'd wanna get it powder coated and ceramic coated. Open to hearing your thought though
Auto tune is always adjusting for the perfect air/fuel mixture. A dyno tune is the same, but for that instance only. When you ride differant altitudes and temperatures, ect. the autotune will adjust.

Any luck in finding it? And also, wouldn't I have to have a laptop connected to it at all times while riding for that?

Haven't looked for it yet, been busy but I know I have it. And no you wont need a laptop to ride, lol. Only hook if you ride somewhere out of the ordinary and want to save that map for when you return. Or save your own area map, and remove the autotune, stuff like that.

Lol, I thought so. Sorry for a stupid question. And no worries, take your time. I guess the only question I have left is where did you weld the bung on your exhaust? Do you have any pics I can use for reference?
Also, where did you tap in to provide power for the auto tune?
I never installed it. Supposed to install bung about 10” after the header leaves engine. And the power can be tapped into the ignition.
