which 240 kit?

[roger489]

hello guys and gals. id like to get a little input from ya. this past weekend my blasty puked the piston out the silencer. the stock cylinder was already at 68mm, so time to find another one or resleeve. i found a guy here local that has a complete la sleeve bbk, and a vito's bbk with standard and hemi head. smae price for both. a steal really, but any way, both stock 72 mm bore. which one should i get in your opinions? and is a 34mm pj carb is big enough for these with a 3mm stroker crank? thanks in advance

 

[Awk08]

the la sleeve bbk is far superior to the vito's
and i'd say that 34pj is on the small side for either, most guys run 35/36's with the bbk, and even some 38's

Get the la sleeve kit vitos is junk and the la kit comes with every thing but a carb which should be a 35

You have to ask whether this is a LA sleeve "sleeve" kit or a LA sleeve replacement cylinder.

If it's a replacement cylinder, the port layout is far superior to the stock or vito's cylinder.

If it's a "sleeve" kit, the port layout is nearly identical to factory and the vito's triple exhaust is better.

to find out the differences in cylinders watch this vid by Ken

^^^^ good link for identifiying the LA Sleeve replacement cylinder from the others.

The only way to identify a "sleeve" kit is to measure the bore diameter and confirm that is it 72mm.

 

[roger489]

Its the la sleeve bbk, it's got the spade shaped intake opening and is Thebes shape not square like the vitos, and thanks guys.

 

[sicivicdude]

Well, how much does he want for it?

And when are you going to pick it up?

 

[98blaster+4]

then in that case lasleeve all the way you wont regret it

i have the vito's bbk with a 73mm. i like it never had any trouble with it.

 

[sicivicdude]

It's not that vito's kit is chopped liver... it sounds bad to talk about it that way...

It's that the port layout and cooling fin design on the LA sleeve cylinder is better (read: puts out more power and less likely to overheat)

The vito's kit can lay out some serious horsepower but if you had to choose between a Vito's 240 kit and an LA sleeve 240 kit, you BETTER go with the LA sleeve 240 kit.

broken piston

damage caused by skirt going through transfers

pieces of piston embedded in crank, and all bearings

 

[roger489]

sorry for the huge pics guys, darn iphone

 

[sicivicdude]

huge pics are really nice to be able to see the carnage.

You will have to split the cases and pull that crank. If you are REALLY lucky the crank survived but the crank saddle bearings are ruined.

Also, flip the case over and take a picture of the bottom. One whole US dollar you have a fracture somewhere around the case.

 

[roger489]

That's the project for this weekend. I'm not even gonna mess with that crank. It'll get a stroker put in. Everything new, bearings, 3mm stroker, la sleeve bbk, seals except the cases, if they are ok. It blew at full tilt. Lol

 

[sicivicdude]

Are you going to get your cylinder ported for the stroker?

It has probably beat the cases, you'll find the damage after it comes apart.

 

[roger489]

I'm planning on giving Ken O a call when I get the jug and and bottom end together. And have him set it up for me

 

[roger489]

oh yeah! its busted. one the other side the bolt hole is eggshaped and beat up but not broken. i picked up the la today.

 

[UncagedShadow]

Probably gonna need to swap that case out with another unbroken one.

 

[sicivicdude]

Just as I suspected....

That size hole can be repaired using aluminum blazing rod. Is that all of the damage besides the egg-shaped hole?
