[QUOTE="canuckxxxx, post: 103329, member: 2409"] OK so I pulled the manifolds/runners/plenum off the bike and put 1 1/4" OD sleeves at each end of the fuel hoses. I cut pieces off my grab rail runners. At the plenum end I made the sleeve long enough to go from internal end of the spigot out to about 1/2" into the end of the fuel hose. At the manifold end I made the sleeves 1/2" long which is just long enough to back up the hose clamps that are squeezing down on the rubber part of the OEM manifold. Put the whole thing back onto the bike. BTW I took out the cross bar that goes between the top of the top engine supports because it was getting in my way. With it out I can get at the carb bolts way easier. I started the bike up and let is run for about 10 minutes until the heads were pretty warm. The bike seems to run exactly like it did before I put the sleeves in. Idles nice, once warm, but there's some hesitation when throttle is opened quickly. The plenum is ice cold even when the engine is warm. I put my heat gun on it for awhile but it doesn't make much difference. What I mean is that as soon as you take the heat gun away it is ice cold right away. I think it will take a lot of heat to keep the plenum warm. But I think getting the plenum warm is necessary and would make a big difference. Until I can reach in there and feel the plenum warm I cannot make a judgment on the manifold. As per Dan's suggestion, I am still going to get a can of ether and check for vacuum leaks.
