Howdy, my friend has a 250r with a 310 big bore kit. He doenst know what kind it is, because he recently bought it. He needs a new head gasket but cant find it. Oh, and the gasket is paper. He also said "Not a o-ring because thats what everyone else had" Are there any other ways to solve this if he can't find one, other than buying a cool head?


Thanks in advance guys.

 

Does anyone know if a cr250 gasket would fit/work?


Thanks once again.

 

Is it a Nik's cylinder?? Look at nacsracing.com, or lrdracing.com, just tell them you have a 310 niks jug and you need gaskets for it.

 

Thanks, he emailed both companies, because he can't find out what kind of kit it is.


Anyone else know anything about it?

 

well.. if it is a niks cylinder you can tell what they look like.. Actually, Most big bores nowadays are niks cylinders EXCEPT for Paul turner jugs.. They make their own.. but every one elses that isnt a hybrid is most likely a niks jug..

here's what a niks jug looks like, it has distinctive water jackets that stick out
