Been having this problem the last couple days, the bike will loose power, not completely, just a serious reduction, like its not running on all 4 cyclinders. Usually only for a second or two then back to normal, however yesterday it was for a couple minutes.
I also noticed that the tachometer stops working when this happens.
Doesn't seem to be heat related, when it happened yesterday I had only gone less than a mile and it cleared up after a couple minutes.
I spent the morning checking and cleaning all electrical connections (spray contact cleaner and dielectric grease), replaced plugs, cleaned airfilter,etc. The battery was a little low, so I will pick up a new one next week.
As with any intermittent problems, it seems fine for the moment,,,,,,,,,,,
Any suggestions would be appreciated.
