I have a 91 XR150 ser# oc267202
This question is from a beginner, working on my own motor but from the past experience i have had from a local repair shop i cant do any worse. The question i have do the switch boxes work independent of each other. I know there is a jumper on the white-black wire connecting the boxes on the top left lug. The reason i ask this is the idle stabilizer should hook to the outer box via a white-black wire and red-white stripe. After looking at mine the stabilizer is hooked to the outer box and inner box would this pose a problem. This all started b/c my boat would bog under a load at 2000 rpm. After doing some reading it would appear the high end of the stator is not doing its job. So i have decided to replace the 40amp stator along with both switch boxes. The fuel pump rebuilt, carbs cleaned and a compression test on all 6 cylinders at 90. The motor will crank and idle on muffs and does fine in the water until i reach 2000 rpms. I would appreciate any thoughts on this. Thank You in advance.
