66e bigbore sleeve question

[WaveDemon]

is the only way to get a 927 (from an 800) to bore and replate or is there a drop in sleeve to avoid the plating?

If you can re-nik why would you not want to. Nicasil dispates heat better, you only have to replace the piston vs. piston and rebore and nicasil resists seezing better but I'm sure there is a sleeve out there.

 

[dbrutherford]

Did you look at LA Sleeve? That would be my first guess.

 

[Idok]

you could probably buy sleeves from WDK (he might make them in house)...I dont know if he uses nik or if its a std. sleeve..

Guys Nicasil cylinders don't have sleeves,can I get a duh huh? You bore the aluminum out to the desired bore diameter and replate them.of course you can bore the cylinder out and put a sleeve in there but as said earlier the heat dissipation is much worse and you will always get more power with a plated cylinder.

Dasa/Racers Edge has sleeves for the 66E that you can use with 87mm pistons.

thank you. that's what I needed to know.


if I bore and plate I'm stuck always replating. if I get a sleeve I can bore it myself and hone if needed. not to mention how much easier it is to port a sleeve out of a cylinder and then match the ports to the sleeve.

The LA-Sleeve part number YA-5356 has a maximum bore size of 81mm

The Northwest Sleeve part number 1451 has a maximum bore size of 82mm.

If you want to go with a larger bore they'll have to be custom made and the price will be 125 bucks a piece.

I see, the sleeve that is in there now is from SBT and only will go out to 81 too.

if I go with a custom sleeve can I tell them what porting I want? that might be the best idea yet.

my 66e has been resleeved, but its not a BB sleeve...


is there a way to tell what kind it is???

the only reason I know what mine is, is because I bought it from tom21 who bought it from sbt.

To the best of my knowledge the replarement sleeves are not marked anywhere,so no you won't be able to tell.

Yes....... P.V. or Non-P.V. with your own port timing specs and maximum sleeve O.D for the cylinder casting.

What companies do these?

Measure the outside diameter at the bottom of your sleeve.

The NW GP800 sleeve should measure 3.400" and the LA-sleeve will be a bit smaller.

What companies do these?

Either Northwest or LA-Sleeve will custom make sleeves to their specs or yours.

Here's some pictures of the LA-Sleeve for the GP-800

punch it out to 90mm and nicasil works like a champ makes it a 992-- fx69boys fx1 is still running great-- he is retarded and always gets water in his motor, but so far hasnt hurt anything-- very torquey-- i think it uses 1200 cyls though-- i dont remember what the difference in cyls are

 

[WaveDemon]

port timing on the 800 and 1200 is the same. the transfer port is wider on the 800 nearest the exhaust port on the bottom of the port.

 

[yamahammer]

right on.

 

[WFO Speedracer]

Btw replating runs about $135.00 per hole,so buy the custom sleeves if you want ,you are not coming out cheaper to do so.

 

[vomitspot]

i thought you were going to put the 1300 cyl on there?
i just picked up a set of 3 on gh for 345
2 of them are in primo shape #3 has some issues
prob gonna be dropping on my 66e soon
