Are you running the KN filter on the Pro Design alloy mount, or just the stock plastic piece with 2 screws securing it to the box?
You could just put the stock lid back on(course youd have to buy one first)and vent the top with some of those little 1" foam filter inserts. That would be LESS susceptible to mud and water than no lid at all. I believe you will need to cut the underside of the lid to clear the KN filter and Pro Design mount.
Alba makes an Aluminum lid with pre drilled holes....claiming Personal Water Craft techology will not allow the water to enter. ITs like $86!
I dont reccommend putting the stock lid on without some of the vents, being your cylinders are ported, your motor wants to breathe.
On my Banshee, i run the Holeshot 20-11-9s on ITP 9x9 .190 with reinforced race rings on the rear. They slide well, and handle [email protected]
Up front i have the MAXIS front 21x7x10s on ITP 10x5 .190 with rings as well. THey turn and handle great for [email protected]
However, ground clearance is an issue,as i countinually strike the skidplates and inside of front rims with rocks, so my future plans are the ITP Holeshot 23-7-10 up front and the 22-11-9 in rear. Of course I will change my gearing to compensate. Another reason for adding taller front tires is because with the longer a arms, i can bottom out the frame to the earth. I would like to prevent that from happening anymore!
As far as .160 rims, dont hit rocks with those. I have folded up .190 rims that were equiped with race rings! They dent on minor contacts. One time, i hit a rock so hard, it bent all the way to the caliper, and it was locked up to say the [email protected][email protected]
You can talk to me whenever ya like, i speak Banshee!
