i have spent all day today working it over, not just due to the exhaust, but i did get the tape and it works quite well, i also have found a kickstand online that mounts in a way that should not interfere with its operation. i also wrapped the manifold in aluminum foil and used 10 separate hose clamps to keep in from moving, along with cutting the copper pipe down to 2", which both helps with front wheel clearance greatly and allows it to rev at the perfect speed for my gear ratio. sorry i didnt get back to your email, thank you for your quick response, the pipe works wonders, even with just a dellorto sha carb. after getting it mounted right it worked fine, i think the issue is that the engine is tilted forward and on a mountain bike, so getting it mounted just right is slightly challenging, but with some time and patience it most definitely pays off. im still looking for a hoist that isn't ceiling mounted but im sure i can just rig something up if necessary. thank you for your time!
