has any one used this? is it worth the bucks? how much higher in jetting did you go?

 

You would need to jet like it was an open airbox. If you ride where it's dry as a bone just take the airbox lid off. If you cross creeks and stuff you might want to use the airbox lid from Alba. If you cross anything that is higher than the carbs I would keep the stock airbox lid.

 

Remove the air box lid and jet the carbs. I have a 98 banshee with tommies and my carbs are jetted at 300 with no air box lid i also run a kn filter with prefilter and a piece of panty hose on the top of the box where the lid was. I also have done the same with my 87 LT500 and 95 TC405ex
