Exhaust question

petenz · Super Guru

yes

I agree with Pete. If the snorkel has been removed then it makes sense to remove the restrictor wink

Hey all.
Love this bike.
Still saving for a fmf q4 pipe. In the meantime is it worth cutting out the restrictor in the end of the header pipe with the standard Aussie muffler?
Will it make any difference power wise?
Previous owner already cut snorkel out

Thanks guys
with out a doubt take yhe restrictor out .
and in my case one size up on the pilot jet and alls good

Thanks guys. Down to the garage now to cut it off. Will prob move the needle clip a position or two in short term till I get a new pipe and rejet properly.

leigh · Senior Member

All done. Defintely much better.

Should have cut that off ages ago.

Good to hear you have released the inner beast smile

Could tell as soon as I pulled out of the drive it was more responsive.

Subtle but quite noticeable. Didnt do the carb yet. Will check the plug after a couple of rides and raise the clip if I have to. Till I get a new pipe and rejet. Still has standard airfilter at the moment.

Go the ttr!!

I have a GYTR rear pipe on... I put a short header pipe from Brian on..

made the motor rev quicker & more responsive... no noticable power in crease...
