Blaster Blaster 1200 conversion on temporary hold :(

[96superjet]

Picked up a 98 XL1200 with a suspected blown cylinder for $800. Thought I could just tear down the top end and send the cylinders out for a fresh bore and honing and put in a new set of Pro X pistions and be set for the rest of the conversion.

Well I'll just let ya see what I saw when I got the rest of the motor torn down....




So.... what's gonna be my least expensive way out of this. I'm gonna ask the machine shop that's gonna do my bore and hone if they think they can do anything with the cases.

Will SBT sell a matched set of cases and a crank alone and not as a whole package the way they typically do? Any suggestions would be greatly appreciated. Thanks.

Bummer bro. You're in it for the whole thing now... crank, cases, pistons etc. I doubt there's anything they can do for those cases, they're probably toast. Thats the unfortunate thing about buying a non-running donor. You can't see underneath the motor to be able to tell if the cases are cracked.

I dont know the answer to your question about SBT. Obviously they'll sell the crank, but they don't typically sell cases without the rest of a built motor. If it were me I would start hunting for some used good cases. You'll have to bite the bullet on the crank and just get it rebuilt.

I encountered a similar deal two weeks ago. I bought a gp1200 for the triple rack for my buddies Kawi triple and the pump for my brawler build. Anything else was going to be bonus.. No bonus here. Check out this carnage

SBT does not sell cases and they do not do matched cases even in their rebuilt motors.
Those cases don't look all that bad and can most likely be fixed by someone that knows how to weld cast aluminum. SBT fixes cases like those and uses them in rebuilds.

You will need a crank, obviously. SBT is a good source for that. They may charge you extra for the damage on the core.

SBT will accept some damaged cores for an additional welding charge. Your best bet is to send them the pics of the cracks and they can give you an estimate. If your interested I'm an SBT dealer or I'd be happy to answer any questions even if you don't want to go thru me. Feel free to call.

As an update to this saga. I called SBT and they do provide quotes on service work. If you send an email with pictures to pictures@shopsbt.com they will respond with a quote or an email like the one that I got.



Apparently, if the mating surfaces are damaged at all they are considered unacceptable as a core trade. My email asked specifically about the cases but I neglected to ask about the crank. I'll wait till tomorrow email them that picture. I've had enough bad news for today....

you can have that welded and then fill that area they are worrying about with epoxy and mill it flat to the rest of the case. Not much different from the way everyone does ported cases on 62t based motors.

You need to find a willing machinist/aluminum welder who will help you out.

How much would repairing those cases cost vs. just buying a good used set? Without checking, I'm guessing you could buy a set for $200 or less.

I've been scouring Craigslist with limited success and EVERYONE who parts skis on eBay wants $400 for a set of 65u cases :censored:

The 1100 and 1200npv cases are the same just fyi. If you cant find cases to finish this engine build, pm me and I would like to try and work a deal for your 1200 cylinder and electrics

 

[waterfreak]

check pwctoday.com They have many peeps parting out couches on there

Not true, they're different. I think you can clearance a set of 1100 cases to fit the 1200 cylinder, but the intake is different so you would have to address that too. It might be worth it though if you have a lot of trouble finding 1200 cases. There's definitley a lot more 1100 part outs thatn 1200.

And yea, Ebay is completely useless these days.

These are 1200 non-PV cases. (Essentially a triple version of the 760) The only difference should be how big the cases are bored to accept the sleeve skirts. Intake bolt patterns and size should be identical. The 1100 uses 38 carbs while the 1200 uses 44's. That may make the intake itself a little bit different, but not the cases.
It's the same "difference" that you find between dual carb 701 and 760 cases. I.e., little to none.

or buy another 1200 ski and hope for the best! Maybe you get this guy to split up this pair?

I'll concede the intake mani from a 1200 should bolt up to an 1100, but the intake is different in the sense of how it sits on the case. Because of that, you have to clearance the cylinder to fit onto the case because the intake on the 1100 sits too close to the cylinder. It will work, but its different, and not in the same sense of the 701 compared to a 760.

One other thing to consider, not a big deal, but the 1200 front crank bearing has the dowel pin hole in a different location. Most will rebuild with a front bearing that has two holes, so its not usually a problem but it just depends on who you got it from.

I may have a good top 1100 case id sell cheap if it would help. I will have to check, i know the bottom is junk.
