I just purchased an 08 4rt. The previous owner is deceased, and I am trying to sort a couple of issues out and could use some input:
The bike has been sitting for a while with gas in it, and the injector/fuel system seem to be clogged. I have added some injector cleaner to fresh fuel and run through a tank, but am still experiencing intermittent hard starts and bogging at higher RPMs. The bike runs smoothly at lower RPMs, but lacks power. Air filter has been cleaned and the plug is new.
Does this seem like a clogged injector? Any suggestions on ways to clean the fuel system? Any suggestions on what else to check?
The previous owner had dialed the idle speed back to 780 RPM per his maintenance log. The manual specs 1800 RPM +/- 100. Any idea why someone would dial it back this far? Any harm in returning it to spec?
Did the bike originally come with a tool kit of any kind? What was in it/what did it look like? If it exists, I can likely get it from the widow, but I don't want to go rooting blindly through her garage.
Thanks for the help!
