My bike has developed a problem ever since I had it shipped to Italy. When I ride with the bike at steady throttle I get surging. Also when I roll on, there is a pause before the bike responds.
When I bought the bike, the carbs were in bad need of rebuilding. The bike sat for God knows how long, and fuel would just pour from the rotton seals. So, I rebuilt the carbs and cleaned/replaced all the jets. I then balanced the carbs and set the idle. All of this was done while in Utah, and I rode the bike for a whole year without problems.
When I shipped it over to Italy, I ran fuel stabalizer through the bike and then drained the tank and carbs.
This problem is intermittant. It is worse on some days, and sometimes is worse in higher gears. The only mods to the bike are a K&N filter, which is clean. I also double checked the fuel tank, filter straws, and fuel vacuum tap, and all look fine.
Any suggestions? I have a Dynojet kit to go into the bike but I don't know if this will fix the problem.
