Hey guys - so I've been having a problem with my bike... here's some bg info.
Bought the bike in October (guy had a buddy die on one and hadn't really ridden in 3-4 weeks - same gas had been in there). I rode the home back 3 hours and didn't really get a chance to go all out as it was like 30 degrees and was trying to stay warm - put gas in it when the gas light came on. Rode the bike twice and layed it down..
Flash forward to January (with the same gas I put in from October). I had started the bike for 10-15 minutes or so every couple of weeks between the crash and when I finally got it fixed up. But went riding once or twice and noticed a dramatic loss of power at high rpms.
For example, in first gear, I get to about 9.5-10k rpms and the bike starts to "chug." Maybe that's not the right word, but the needle slightly bounces and I can't get any higher. Only once or twice have I been able to get into the red line area. This kind of thing happens in every gear (but the depending on what gear I'm in, I may experience the issue at different RPMs.
Not sure if it's related, but it also feels a little sluggish or slow to take off in lower RPMs?
Flash forward again to two weeks ago and changed the plugs as well as ran some seafoam through the system. Noticed an immediate difference. Things began to look up, but couldn't ring it out until a group ride. Also ordered an 8-cell MOTYdesign battery and put that in.
Here is what the spark plugs looked like:
Now, flash forward to today - the problem is still there. New spark plugs, new battery and it seems to get worse the longer I ride.
Went on a group ride today and everything seemed fine at first and after riding an hour or so, it exponentially got worse. When I took a break at the gas stop, things seemed to get a little better but the issue was still there.
Any ideas or any of you experience similar situations? ECU? throttle bodies? dirty injector? cam chain?
I do not have a power commander or bazzaz
Thanks for any advice/input.
