Yes, I was thinking that since lean equals heat there go the valves. That is interesting that the head temperature is actually lower than at 14.7.

Come to think of it, I have wondered how age of components might effect wethead performance over time. Two O2 sensors communicating with each other and other refinements which increase complexity all to what end? Kind of makes me yearn for a good old airhead as in "simple by choice". It's no wonder most wethead owners opt out before the warrantee expires.

There I go, showing my age again. old

Can anyone comment on the injector set found here

http://injector-rehab.com/shop/1200...150-GS-1100S-NEW-Injectors-Included.html

and how they would fit into the improvements described in this thread if installed into a 2004 R1150RT.

This is an immensely interesting thread but I think I need to go back and start reading again at the beginning.

The kit here should work fine but I went with the German set. There’s more detail on how they do matching and their specifications on the web site. If you use IR I recommend asking them for their matching specifications, especially how many ROMs and pulse widths they match at.

I spent the weekend riding through the very narrow, twisty, hilly roads of Cape Cod’s National Seashore in Wellfleet. These aren’t fast roads, but speeds between 30 and 60 mph are possible. The LC-2 at 8% more fuel (AF setting 7 or 8) creates enough torque at low RPMs that I could ride in 5th gear almost all the time during the hills and turns with the speed varying from 30 to 55–no shifting! The matched R1200 injectors have made the engine feel so smooth in that range that it’s like I’m riding a bike with an automatic transmission. The pairing of LC-2 and matched R1200 injectors is great.

I also did some steady riding at high rpm. The matched R1200 injectors have resulted in a smooth engine through about 5000 RPM. By 5500 there’s a slight vibration I can feel in the tank and by 6500 there is a slight vibration in the handlebars that diminishes by 7500 RPM. (I’m going to do some riding with the Harmonizer connected and see what the TB balance looks like under load.

The matched R1200 injectors initially seemed to improve starting but after a tank of fuel with time for the Motronic to remove the extra fuel, I’d say starting performance is about the same on my bike—though the warm idle of the bike is rock solid now, better than before.

Overall, I’m glad I bought the matched injectors, they’ve smoothed out the engine noticeably and pair well with the LC-2 which adds torque. However, if my budget only allowed for one of these options, I’d get an AF-XIED/LC-2 before the injectors. The torque improvement from lambda-shifting is terrific and the richer mixture alone reduces the engine’s sensitivity to injector imbalance.
