I can't get my 2003 1600 over about 2k-2.5k RPM
under load, struggles to get up to 70 mph in 5th.
I just got the bike, I have plans to take it into a local bike shop for a first maintenance; oil, filters, brake pads, spark plugs, and swap out the rims with some others I had to get (ones on the bike are rusted horribly enough to maybe cut tires).
Basically as I increase RPMs
the starts to sputter and lose power somewhere around half throttle. equates to about 60 mph in 5th. I have slowly nurse it up to 70mph but that is it.
It does appear to have too much oil in the tank, I've read to keep it at a strict 4qts?
What else should I have checked if it is doing this after that maintenance? Bike is stock except for exhaust, air filter, and bars. Low mileage for a 14 year old bike (23k) What is the best way to check those things?
I am thinking about running some sea-foam through it before I take it in for maintenance, so that I am not running it past the new plugs.
