    Carbon fiber pump tunnel reenforcing techniques

    So ive been looking online at materials to do carbon fiber pump tunnel reenforcement on my 06 RXT since i have everything removed from the back of it for easy access. Whats everyone using as far as materials and how many layers. Also whats the best way to prep the tunnel surface to ensure the best adhesion and integrity?

    have a look in the 2 stroke section of Yamaha, tones of info on this as the GPR had issues in this area. although the GPR has an SMC hull the principals will mostly be the same.

    they didnt really have issues...but once you get things exposed..you have to get rid of any shine..on the surface of the glass ..do 36 grit if you can ..

    epoxies are great but dont like to stick to poyester resins...so go with polyester....it is cheaper anyway ..

    have everthing preped..cut fit and organised before you mix any resin...keep a pale of acitone handy plenty of rubber gloves..get a bunch of disposable 1.5 or 2 " brushes and dab dont brush ..work any air pocket out and remember the strength isnt in the resin it is in the fibers..so use just enough resin to completly saturate it no more..use the proper amount of hardener measure it no more than say 10 cc per quart..other wise it will kick on you before you have it all wetted out..

    as for thickness..the weight of the glass (how may oz)is how they do thickness.. i would say 3 or 4 layer is sufficient..of any glass/ carbon that has any weight to it the thinner bi weaves conform better to curves..

    Im assuming because of the chop that i ride in i have some stress cracks in my tunnel visible from below. i have things pulled out of there so i figure it couldn't hurt to shore things up.
