I have a 1985 Honda Elite I have been working on for the last couple of months. It starts and runs great but when I'm at top speed the bike intermittently suffers a loss of power. This loss of power will occur at the very top speed (58mph) I have been able to get the bike up to. I've replaced a lot of parts to address this and other problems I had with the bike early on. The gas tank has been off and totally cleaned out. The vacuum petcock has been replaced. The carb and the rubber manifold have been replaced. I just put in an aftermarket market CDI and a new coil. When the CDI and coil didn't do the trick I replaced the vacuum hoses to the petcock to try and ensure my problem wasn't do to a lack of fuel. A clue seems to be when the gas tank is completely full the problem doesn't come up or isn't as pronounced. Anybody have any ideas? Other than this one problem it's a cool old scoot without too many (under 6k) miles. I want to be able to keep using it safely. Thanks so much for your help!
