Anyone know if a sleeve is required for the 686cc kit? I know it is mandatory for the 727cc big bore kit to have this sleeve installed, but is it recommended to have it on the 686 as well? Will it hurt anything? The sleeve is only about $100 so it might be worthwhile to install if it is more rigid than the stock cylinder? How is reliability or maintenance affected by the 686 kit?

 

I'm not sure if you can run it without a resleve but i do know that you should. If you dont i bet you have a big chance of braking something very important. If i was you i would by it anyways for safty for a new 686

 

I agree cuz I had to get my re-sleeved bigger.

 

No one ever seems to speak of having a sleeve installed and the craycraft signature 686 does not even include it in what you get for their package. Does anyone else know if a sleeve is required for a 686?

 

i think you just need to bore it out

 

No, you do not need to resleeve it for a 686.

 

nope I did mine without a sleeve and worked fine! I have traded it so I don't know ifits still going or not[img]i/expressions/face-icon-small-smile.gif[/img]

 

No Resleeve is required. For a 727 then yes.

 

so how do those craycrafts run anyways.. I heard there crzy

 

i'll let you know in 2 weeks
