I put a HMF pipe on my son's 300ex, I went to the HMF website and changed the jetting as they recommended. Also put in a UNI airfilter.
it revs good runs good until you start winding it out. once it hits 3/4 to nearly full out it starts Porky Pigging... de de de... de de.. de
You get the picture.
I've moved the clip up on the needle and back to the middle.. no better. adjusted airscrew.. even cussed and fussed at it.
I've never in my life ran into this! It does pop a little on decel..
Any body got any ideas?
