Superior Sleeve

[2004LEBanshee]

That's what I was thinking.

hmmm that is actually an intersting top end. 85mm bore with stock crank. i'd like to play with it.

 

that top case has some work to get that cylinder to fit right. also looking at the pics and from some of my limited experience there is more work that could be done to the top case to improve it..

 

i'd love to machine it out for the pv's and use them as well. wonder what 85mm piston uses a 16mm pin?

i bidded 800 and people wouldnt stop bidding so in the end i had to pay 854 so thanks to all the other people i had to pay a high price.

i highly doubt i CANT use the top case half,that would be stupid thinking if CANT use it when you CAN buy seperate case halves.if i cant then ill pull out the dremel and hack it myself to fit the bigger sleeves.but besides all the bs and high price i cant wait to get it all together

You CAN"T by seperate case halves from Yamaha or Mattoon!!!!!!!!!!!! The reason being is that the holes for the crank and tranny bearings are machined to final dimension with the cases bolted together. Thus due to minor variances in halves, that are negated by being machined as a set, you should not mix and match case halves. Some guys on here have done it, with mixed results. It worked for some, others had problems. Yamaha made the Banshee for 20 years and I do know this can lead to alot of wear on their manufacturing machines and variances in machine work that wont show up in a case set, but would show up in mismatched case halves.

 

The only place you can buy seperate case halves is from private sellers or used parts dealers. OR if you have cases that split apart sideways instead of up and down, like a Blaster or 250R, you can buy seperate case parts. I know Honda does sell cases seperately.

With a dremel.......LMAO.....................there has to be a better way..............................Maybe call a site sponser spend 150ish to do it the right way................

 

 

 

 

 

 

Have you got the cylinders yet......are they really 85mm.........what piston is.......# on the top...............

[camatv]

hmm dont take this the wrong way..

 

top case will need to be filled, port matched, welded, center bored for the sleeve and reinforced to accept the cylinder..

 

its not a cub..

[ban565]

if it is 85mm and stock stroke it would be a 612cc

[BLOODRAGE]

so basically i am screwed if i dont send em out.oh well itll make a good paper weight

[RadarRacing]

Youll probably have less than $2000 in that topend and many of the superior sleeve 10 mils were in the 80-95hp range.

[BLOODRAGE]

holy smokes

deffinetly gotta get this jug installed even if i have to send my cases to a sponcer.how much hp could i get with a stock stroker?

[johndeere10]

yea i would send it out i have a 10 mil superior sleeve 521 cc and it made 114 hp ..so did you get the numbers from the pistons yet .and i dont think the price was to bad they are 2000 new

[BLOODRAGE]

it wont be here for another 2-3 weeks.remember im in canada and the customs like to fuck us over

[BLOODRAGE]

good news.ive located the bottom case half and the guy is willing to sell it to me.so looks like ill be getting this superior sleeve bbk running after all

[camatv]

well why didnt the cases stay together?? what the hell

 

if you give up on this motor let me know. i might like to try it out.
