puting a HMF ironman series exhaust,k&n air filter with lid off where do I start at with my jetting altitude about 200ft

 

i purchased a jet kit but it recomends a 128 main jet and everything i read says a175-180 with a slip on pipe and k&n with lid off....can someone help

 

the first thing is to let your machine thoroughly warm up go for a test drive then pull the plug check if your rich or lean and from your test run start adjusting your carb accordingly wich is idle to about 1/4 throttle is controlled by pilot jet and air/fuel screw mid to full is combination needle and main jet.Also remember to only change one thing at a time in small increments.Have fun and I will wait to hear how stoked you are from getting it all tuned in.I personaly think tinkering with my machines is half the fun
