I found a 88b engine case with the timken bearings in it. It is already polished, and clear powder coated and most importantly for alot less money than having my current cases modified to be like these. Aside from the fact that my vin on the cases would not match my cvo cases ( so I guess it becomes a custom, I don't plan to ever sell her) Should these work? Or is the bore in the actual cases different? I am currently under the assumption that the cases are the same ( except for the mods listed) by looking at the 88 to 103 upgrade kit........am I wrong?

Aside from this if they are the same, would I be accused of having a stolen motor by some cop or would I have to have my title changed to reflect the new vin on the engine case? It obviously will not be a matching vin.

Another point leading to my consideration of doing this is these are STD cases 356 T6 "A" Prime alloy with a tensile strength of 45,880 psi........is that any benefit compared to the stockers?

You will have to carry some form of documentation to prove that you own the engine if it doesn't match the VIN on the frame.

You will have to check with the DMV of your state to see what the requirements are.

I can’t answer your other questions, but I can guarantee that if you come across a cop who knows his or her bikes, it's going to be seized and you will be taking the bus!

You’ll eventually get your bike back though, but not without a fight.

Do you know what year the cases are?

[sefatboyscott]

I would assume the year would be 2008. They are aftermarket cases........new. It just works out cheaper to buy these than to send mine off first for the bearing upgrade, then the polishing then the powdercoating. I can just buy these cases for under 600 bucks and be done with it, or at least that is what I am trying to figure out if I can do.

Also, for some reason I have some peace of mind that my cases were not Altered to put in the Timkens they were manufactured with the INTENT of using them, maybe its just all in my mind. I never claimed to be nice to my motor over the past few years. I have no idea what kind of stress I have actually put on the cases. I just want to do a rebuild using fresh cases I guess and these fit the idea of what I am looking to do. I just am not sure I am even looking at the right thing as they are listed as tc88b.

Think I could get my stock ones bearings replaced, polished and powdercoated cheaper?

Do you have a link for these cases? I checked out STD's website and only saw evo style cases.

For what its worth I would not be concerened about having the timken conversion done to you cases. Jim's now has a sleeve that gets installed into the case for the conversion that does not require any machining. Hoist had this done on his 110" cases. The cost is about $500 for the machined conversion from Zippers or STD. The sleeve should be a bit less. Not sure how much the polishing and powder coating.

Ok, to tell a bit more of the entire story I posted a similar question and on someones recommendation on that site I was directed to these cases here:

http://www.cyclemodelbcases.com/index.cfm

another person who I trust as far as business goes but his bike knowledge is not proven to me has offered to get me a set of brand new, polished and with the Timken with the only difference being the ones he is offering being:

these are STD cases 356 T6 "A" Prime alloy with a tensile strength of 45,880 psi

Which is why I asked is that any benefit compared to the stockers? As I know the STDs are aluminum so they would be lighter not heavier and I have no idea what the tensile strength of the stockers is , so nnumber one I don't know which bore size to get and two I don't know if they are stronger or weaker than what I have now but the price that I can get them for is half the money.........it's not they are worth half as much, it's just that I can get them at cost. I have a friend who may be wanting to do me a great deal but I am not secure in how great of a deal it might be.....saving is great if they work but not if they don't.

To make it simple I can get these cases for BRAND NEW for only a portion more than the method as described above......is it worth it and what size does the bore need to be? That of a stock 88 or are the CASES on our bikes bored over?........I always assumed that it was just the cylinders not the cases.......hope that clarifies the issue.

Just seeking others opinions and ideas on this matter. No final decision has been made.

haven't heard of those cases...believe 356 t6 is aluminum...the cases that came on your bike have the same size spigots as 88 and 96 cases...it's only when you go 4" or bigger bore that the cases have to be bored

[rednectum]

STD issues a MSO with every case set, this is your legal record of ownership. they only issue one-----so make sure you get the original.

ordered many cases from STD, that price seems light. also always had to send cases out to have polished, steves metal polishing, but they were panhead/early shovel castings. the factory cases withstand the rigors of drag racing, they are plenty strong. weak point being lack of timken and studs.

Thanks for the input guys.

I am not sure STD is even marketing these cases yet. Apparently they actually have them milled from third party machine shops. My friend that offered me this deal is a machinist that works for an engineering company. He claims they make the same cases as STD at times and he has them already dialed in his CNC machine and the polishing and powdercoating he will do for me as he says it's not a big deal they have lots of down time...... I might give him a shot, seems like I cannot go wrong with the price. I will find out more about the Statement of Origin deal.

What is wierd is that his company does not specialize in motors at all. They make extreme low tolerance molds out of aluminum and steel that get filled with foam and pressurized. The final products are typically floatation devices for aquanautics like the "Alvin" that explored the Titanic.

Maybe they buy the aluminum is such a large quatity that STD could never get it cheaper and this is why they are outsourcing this "future" product, perhaps they are actually just prototypes. I have to research this a bit more. I also checked STD's website and could not find twin cam cases on their site.
