Thanks for the response, PMC. I ride mostly back roads in rural Maryland with a little highway and town mixed in. I'm at a loss as to what might be going on with my bike. The air filter is like new and wouldn't be the problem. I talked to the dealer that did the Yosh tuning on it and he said they could try to do more adjustments but it's not even close to doing a custom map at a PC Dyno center. The PC tuner I talked to yesterday told me it would run $300 for a custom PC map. I'll keep that as an option but would love to find a cheaper yet effective fix. Maybe a second try with the Yosh would be the way to go. Also, I've wondered about the throttle bodies, but don't know if the problem could at all be related to TB adjustment. Any thoughts?
Yosh Box/PC III Question
I have a DL1000K5 that has had the typically discussed FI problems at lower RPMs. I am the second owner of the bike which just turned over 5000 miles. The first owner had installed a PC III on the bike which never seemed to solve the running issues. When I took the bike to a local Suzuki dealer to discuss what they might do to help with the problem, I was told about tuning using a Yosh box. They told me I should disconnect the PC prior to doing the Yosh procedure, which I did. The bike now runs very well except for some sputtering/stalling out while at idle. Although the engine runs without hesitation above idle, my fuel mileage has suffered a lot. Before the Yosh tuning, I was getting 39-42 mpg, however, I now get 28-30. Can anyone tell me if this is normal and if it can be retuned using the Yosh to still run smoothly without the drastic reduction in fuel mileage? The bike has stock pipes and air filter. I guess my other option is to reconnect the PC and have a custom map done at a tuning center. I'd like to know what sort of fuel mileage others get and would really appreciate any suggestions on fixing this problem.
