I followed dyno jet instructions

 

And just what do you mean by "opened up airbox"???

 

Heh, I missed that. Yeah, drilling and cutting the airbox will gain you nothing in power, however will gain you plenty of headaches. Find a used airbox and go back to stock.

 

Yeah. In the old days, pipes, jet kit, K&N and removing-modding the airbox lid could net you 15% to 20% in horsepower. Those days are over.

Our VTRs just might be the first bike where removing-cutting-drilling the air box lid nets you nothing in peak power and makes tuning for throttle response and drive-ability virtually impossible.

 

yea, it's like the whole front of the airbox is gone.

 

Your bike can be tuned to run fine the way it is now. I have nearly the exact same set-up: de-paired, k&n, Mig pipes, Dynojet kit, front of the airbox lid opened up, and mine runs like a top. Very stong, no popping or backfiring. I don't have all the know-how when it comes to jetting so I had the tech at my Honda shop tune it for me. The guy used to race Ducatis and used to own a Superhawk. It wasn't easy but he finally got it just right. I don't think the airbox is your whole problem, plus with it opened up you get all that great intake noise!

 

Oh yea, I forgot to mention that I live in Denver, CO at 5280 feet above sea level 185 front jet 190 rear clips on dynojet set at #5 postion.

 

I have a 1998 Superhawk and i have a full Two Brothers Racing Exhaust (High Boys) I have no rear sets and want to put some on. Any links and or info would be helpful. Also added a rear hugger. I will post pics soon.
Thank You
