time for new rings!

[400exman02]

@sl66xsv indeed, you can buy them for me if you would like!

@400exman02 Is this with quiet core installed or straight HMF?

[400exman02]

@sikcrx89 no quiet core

you have probably been asked this many times, but do you remember what you changed the jets too? hmf recommends the stock pilot jet and a 165-170 main. what did you choose? thanks

[400exman02]

@FMXkid531 to be honest i dont remember what size it is. all i remember is when i bought the pipe off ebay it came with a jet.

@psychosocial28 it needs rings bad. i just dont have time to fix it or the money right now

[psychosocial28]

Needs rings........ Or valve seals if its cold....... Mine smoked just liked that but i juwt rebuilt it with a wiseco high compression piston and now it doesnt smoke at all

@zman1234boy personally i would rejet it with just a slip on. you wont get much more power out of you bike if you dont rejet it

[zman1234boy]

do you need a full system in order to jet it cuz i was told you can just make way with just a slip on
