I just purchased a 2007 MTS1100 and I'm having an issue with the gauge changing from MPH to KPH. I can set it for 1100 MTS US and it will work fine, but if the power is switched off for more than 2 hours or so, it will change back to 1000 MTS EU. The clock stays set correctly so it's not losing power or anything.
I talked to the previous owner and he purchased a Remus exhaust and a tuned ECU for the bike, and he said that is when the issue started. He's pretty sure that the tuned ECU came off of a Euro-spec bike. So, it sounds to me like the ECU is causing the gauge to default back. There's a sticker on the ECU with numbers 96518207B and 2235SL02, which looks like the part number and code for a DP tune.
I've read that this is a pretty common problem, but I haven't come across a definite solution (other than, I'm assuming, buying everything new). Is it possible to have the ECU and gauge cluster reprogrammed to US-spec without erasing the tune that's in the ECU? If I would purchase a take-off US-spec ECU and cluster, does anyone still do tunes for these bikes?
My other problem is the engine light will randomly turn on and off while riding. There's a code 7.2 Fuel sensor short-circuit to ground in the bike. The previous owner also told me that this is solved by changing the fuel pump wire harness (which he included in the sale, part #51020031A). He found out that removing the fuel tank is a lot of work and never got around to it. Is this something that's also a common issue on these bikes?
These are both relatively minor issues with the bike, and it runs great otherwise (especially considering I paid $1000 for it), but I'd like to get it to 100 percent before next spring. Thanks for any help
