A while back I started getting a CODE 48. A little inspection told me that the motor for my flies wasnt cycling. I disconnected the linkage, but still no joy. Not that it matters much, but I had removed the flies a long time before this issue.
After some Ebay shopping, I found a complete intake set from a 05 R1 ( airbox, injectors, TPS ETC.)for $50 shipped! I figured that having spare injectors and TPS was worthwhile.
I admittedly didnt get to this right away, but there was no harm in seeing the yellow dash light on for a while. And the right time came about when I decided to have my ECU flashed by Ivan.
Taking the used setup apart gave me help in figureing out the method for getting the OEM out. Looking at it, there was no way to replace it without getting it up and out. Loosening the intake boot clamps allowed me to take the intake out of the boots enough so that I could tilt the right side up and get to the 2 bolts holding the motor onto the intakes. I also removed 1 of the cotter pins on the linkage.
CAUTION!!! Take precatutions to prevent dropping any parts into the open intake boots!!! I stuff a couple of shop towels in the boots, & also put 1 under the linkage itself.
Replaceing the unit itself is fairly easy. Actually, the hardest part is getting to the intake boot clamp. backing up a bit, before you take the clamps OFF, make sure that the area is clean of all dirt & grit. Dont want to get anything down the intakes.
After everything is all back together, its time for an autopsy of the dead part. Yamaha does NOT want this to come apart, as there was a serious amount of visable locktite on the 3 bolts holding it together. It turned out to be about what I thought - a plastic gear blew up.
All in all, not too bad a job.
