LA 240 sleeve kit

[97BoredOutBlasta]

anyone running this kit, or anyone know about it? it just drops in your stock cylinder and increases displacement by 40cc?!? it comes with a wiseco 72mm piston, wristpins, rings, and gaskets. are these kits worth using? if so, can i get it ported by flotek, and port matched for a 60mm crank?

well it sure dosent "just drop in" thats for sure. a machine shop would have to mill your old sleeve out and then take off some more to get the big bore sleeve to fit. ive heard resleeving is quite expensive but ive never checked into it personally. but once its in i dont see why you wouldnt be able to get it ported.

well no sh*t it needs to be machined and pressed in, i shouldnt have phrased it that way, lol. i might look into it.

ya you would get your old cylinder "bored" (millings for horizontal planes). i wonder how this would hold up opposed to a whole new cylinder casting.

do it hat is what im runnig and mine is ported with a shaved head and it flys

Vitos makes a 240 kit as well that drops into your stock cylinder. Same as the la sleeve kit. Only problem with them is the stock ports arent big enough for the 240 kit. Jetting can be a issue till u get it figured out. Heat fins arent big enough either I have seen the cylinder crack in half if exposed to water on a hot day. The way to go is the vitos complete cylinder kit around 550.00 I have done hundreds of the drop in kits. They dont make as much power as well as the complete cylinder kit.

ya i was kinda thinking there wasnt much material to spare on a stock blaster cylinder. i could see problems with that. if i do go bigbore, i guess i will get a whole new cylinder

You can install the sleeve in a stock OEM cylinder
The sleeve is cut out and then the cylinder is bored to fit the new sleeve.
The head is cut to fit the piston
I have done several sleeve kits
the 72mm piston changes the displacement from 200 to 240
If you choose the 60mil crank or 61 crank
The porting has to be changed to make the stroker crank work
Using a spacer plate does not work, the port will be off on the set up

in your opinion, are they unreliable or weak in any way? which do you prefer?

hey, you said it. lol "it just drops in..." im actually glad you're not that big of a dumbass I:I I:I. lol

All questions are good, people are at different learning stages.
A sleeve kit is not weak, but is much work for the builder

everyone has a different way of setting them up some work better than others
i wont knock anybodies ideas... but in my ~experiance i would avoid stuffing a big bore sleeve into a stock jug casting ,it makes for poor crankcase and transfer volume plus they dont have triple exhaust which is a huge benefit youd want ..get a real bb kit and stroke it ,do it the right way ,theres a reason they make them!a spacer can be made to work just fine ,some people like milder porting durations than others ..we have the 270-320 cc class pa states championship on 2 motors at bedford blair dirtdrags both run copper spacers ..both will crush liquid cooled ported big bore 250rs or quadracers consistantly on the drag strip with time slips video and track registry standings to prove it .to each his own

thank you denny, i thought the same about ramming a huge sleeve into the stock cylinder casting... i guess i will get a vitos cylinder.

The OEM cylinder with a BB sleeve is capable of big power gains. I do not use triple exhaust ports on the set up. At best the triple ports are a gain on .3hp so I choose not to go in that direction. I focus on the cylinder port work and more important the cylinder head design. MY choice of pipes is the Shearer and Vito pipe. I have tested most of the pipes out there on my dynojet 200IX dyno and have proven that these pipes can meet most people’s expectations. Once Mat Shearer finishes the drag pipe it will completly revolutionize the Blaster drag world of racing. We hope to boost the TQ up to 40 foot pounds.
I will have the first pipe test and will for sure post the results.
