THE358BANSH Posted November 17, 2011 Report Share Posted November 17, 2011 Does anyone know of a manufacturer that carries manifolds for 40mm and larger carbs on a stock sized reed cage? Or another option would be a billet style manifold that uses the VM40-200k style boots? Thanks a bunch! Evan Quote Link to comment Share on other sites More sharing options...
THE358BANSH Posted November 17, 2011 Author Report Share Posted November 17, 2011 these are for 38-41mm - boss intake http://www.alibaba.com/productshowimg/us108193968-262465984-0/BOSS_Intake_Manifolds_for_38_to_41mm_carbs.html these are for 36-41mm - trinity http://www.ebay.com/itm/Banshee-YFZ350-RZ350-Billet-Intake-Manifolds-w-Boots-36mm-38mm-39mm-41mm-/350498821527 38-40,, - modquad http://www.roguemotorsportz.com/i799/Modquad_38_40mm_Split_Intake_Manifolds_no_spacer_Yamaha_Banshee.aspx Those all use the VM36-200K intake boot and get stretched heavily to fit big carbs.

No Limit Powersports Posted November 17, 2011 Report Share Posted November 17, 2011 The vm36 boot will fit a 40mm carb just fine in fact thats what there made for. You dont want them loose or they could leak and/or fall out of the boot. Quote Link to comment Share on other sites More sharing options...

I guess I should have reiterated myself and said 40mm and larger Mikuni and 44mm and larger Lectrons which are 52mm on the manifold side and most commonly use the VM40-200K flange.

camatv Posted November 20, 2011 Report Share Posted November 20, 2011 make your own. UPP's are pretty big and there is barely enough room for bolts to mount them to the cylinders.. Quote Link to comment Share on other sites More sharing options...

I called UPP the other day and talked to a tech guy. The inside diameter of their largest intake is 46mm and he said he thinks it would stretch 2mm max. Oh well, guess I either have to cut the throttle bodies in the lathe or search for a set that has a smaller outside diameter. Quote Link to comment Share on other sites More sharing options...
