Hi Guys!
Could somebody tell me the proper jet sizes for me?
I have a remus exhaust installed and a lunchbox filter.
My main jet is 112.5, im pretty sure its way too small for the rig.

Thanks in advence!

Stock main jet is 122.5. You sure of your jet size? 112.5 would be way too small. 122.5 or maybe 125 should work for you.

112.5 your bike is from where ? turkey or some other ? I don't recall, but somewhere in central asia they had 112.5's
Weird, cos they had 40 pilots in that same country. The bike wont even run with 112.5 if you are to believe my O2 sensor.
OK OK I didn't actually try anything under even 122.5 with the O2 sensor on a stock bike.

Anyway 125/40 is good for a 97. Where are you located though ? UK bikes had 125/40 stock. And adjustable needles.
Cool.

I bought the bike second hand in Austria, its a 20kw version, thats the reason for the small jets. It comes stock with a restricted carb ( theres a hole somewhere in the black moving parts that i cant name )
So that was changed, just like the exhaust but the jets werent.
So the bike runs like sh*t.
And since i could put the stock airfilter back i bought a lunchbox filter.
Thats why i need to rejet.

125 jet won't work with lunchbox. You're using the stock airbox/filter? If so 125 will get you all set.
