air box lid

[NJ honda]

ok i have my carb jetted for a procircuit slip on and i want to run without an airbox lid now do i have to jet again for the absnece of the lid or do u think the jetting already there should be enough...?

youll have to go up 1 or 2 jet sizes.

what main jet are you running now?

when i bought it was already jetted and the guy didnt know he brought it to a shop and they did everything so prly whats average for a slip-on

[Pappy]

most of the quads ive come across that were "jetted" were running rich. there is a lot of saftey in what comes in the instructions for most slip ons and pipes.

on my 400ex, we followed the instructions for my T4 and it wouldnt even run with the lid on. taking the lid off and she ran good, but still fat. i believe that was a 180 main. we kept dropping down until a 155 was good, albiet still fat with the lid on. a 152 worked well so i could run the lid or not.

id suggest pulling the main jet and seeing what is in there. post it, and im sure others in your area will post what they have found to be working.

my buddys at a 170 dynojet with the lid off/modded, but were only about 480 ft above sea level

Try a 160 Main Jet. I am running the same pipe with K&N and no lid....

yeah me and my friend took it out and we had no idea so we were like f it and put it back in and went riding...but i dunno im going to take it to the shop and ask him and prly run a 160 or 170 main and get a k&n with outer wears

I would do like pappy said, go with a 155. you don't need to have a shop do it, just turn off the gas, unscrew the bottom of the carb and insert a 6mm sockit and take out the main jet. Takes 5 min. A 170 will be rich.

I would run a 152-155
