Slow Throttle Response?
I may have a problem with my R6 that has been bothering me. It is winter now so I don't get to ride to really check it out. Any help or ideas is appreciated.
I started my bike up a couple of weeks ago just to rev it up before I pulled the battery for winter charging indoors and noticed some, not a lot, but some hesitation in the revs from idle up to about 6500 and then it would take off. Also in the quick bursts of reving - I know it wasn't good but I didn't let the bike warm up first. I also noticed that after a long rev up to 12K plus RPM the next rev would stutter. I think it is probably the sea foam and octane booster since I didn't measure exactly I just poured in an estimated guess with the fuel. My guess is I'm running too rich with the additives in the fuel but have heard this could be a TPS problem. There isn't a delay from the twist of the throttle to the raise in RPM, just the rate at which the RPMs rise from idle to around 6500 (seems slower). After 6500 the RPMs raise quickly to redline. Maybe it's nothing at all, but it seems off to me. Info below.
This spring I bought a used 03 R6 with about 17K. I only got about 3k miles on it this summer - sad about that. Over the summer I added a PCIII and did the cheapo exhaust cut mod to the stock can. I tried to find a good map but really nothing is running it right. A group of guys I ride with had our bikes dyno'd (mobile station - tuning not available) I put up 103HP and was running pretty rich especially on the low end. I trimmed the fuel on the low with the manual PCIII buttons and it seemed to perk up the bike a little more. I am still running rich from what I can tell because my can is sooting up at the exit.
I winterized my bike, changed plugs, flushed coolant, bled the brakes, topped off the gas with 92 octane added sea foam and octane booster (my typical winter mix for sitting for a couple of months).
