EV, I'm available tomorrow to go help you "de-carbonize" both your feejer and mine. Think an LEO would accept it as an excuse? :lol:
Ahh, no, I'm pretty sure no PacNorWet LEO will accept that as justification for excessive speed. The trick is to get the rpms up and try not to get too wild on the speeds while still using WOT in the lower gears.
Sort of like trying to look inconspicous while bedding in break pads. :lol:
FWIW - I don't baby the bike. And I didn't baby it on break in either. I did a moto man run the day I picked it up, actually did so with a couple other FJRs that day, including our own Warchild riding someone else's new FJR at their request. While I do accept the possibility that the compression was low prior to this, I don't believe it was so all along. This bike was lifting the front wheel on accel alone for a long time, even after 60k. The decline in power, if present, hasn't been noticeable to me. The low readings certainly do suggest it's down on power though.
What bothers me most about this situation is that it's so far below the spec. I expect more from a modern bike motor. Had I been told I was at the bottom of the spec or a little below it, I'd not have been surprised so much. To be 40 psi below otoh, seems excessive to me, even at 88k.
The biggest reason I started this thread is to raise awareness. Information is good. Knowing what your compression is at different stages of your bike's life will help you to see if you are experiencing normal, gradual wear, or a sudden drop that might indicate carbon build up or some other significant issue that needs attention.
As said, I will try a decarbonizing routine with some good nasty cleaning agent and some wot runs after it sits for a couple of days to loosen up the crud. And thanks for the offer Weekend Rider, but I'm no stranger to doing that myself. Maybe just need to do it more often than I have in the past, gas consumption be damned!
wheatonFJR - On the back road two lanes, I use WOT and a double down shift to pass the blockers. Warps time and space and I'm suddenly 10 miles away in clear air. :yahoo: Gots to be careful not to loft the front wheel though.
I hope that has answered the previous poster's questions for the moment. Heading out to the garage this morning to pull the wheels for new rubber, and yank plugs, air filter and do some preventive maintenance as well as possibly squirt in some nasty decarbonizing juice if I can score some at the NAPA or other local auto parts store.
And thank you to everyone for your advice and comments. :good:
