Yes, I have searched and have not found the exact manual that matches my '86 USA bike. Not a Tenere, just a standard XT600. Much of the TT600 is the same, but I noticed the stator/pickup coil ohm readings are different in some aspects. I am having ignition issues and was trouble shooting the coils using info from my Clymer manual. In particular, Clymer says to measure the pickup coil from the red/white to the green white. The readings were way too high so I measured from the center tap green wire to each end of the coil and it fell within the range. The TT600 OEM manual says to measure from the green to the red/white and green to the green/white so Clymer has it wrong. I have found other errors elsewhere as well.

I like the OEM manual's explanation of the deceleration enrichner circuit. Now it makes sense. I just rebuilt two of the carbs and replaced the diaphram/valve but wondered what it actually did.

I am anxious to get my '86 running to see how it performs with freshly cleaned carbs, float levels correct, valves set, 170 lbs compression and new CDI. Last time it ran late last year, it was very hard to start, backfired often and generally ran poorly. I see now that the original CDI was failing back then and now no spark at all and was most likely the cause of hard starting and backfiring. I went ahead and replaced the intake boots as I've learned here and other forums that they responsible for many ill's since they get hard and leak air. So I guess this was a blessing in disguise forcing me to look hard at everything. Now I should be in very good shape once the New Zealand CDI arrives...

With the age of the bikes of that vintage, I feel the CDI's are a major source of problems even before they fail completely. Since I am an electronics tech by trade, I understand why. CDI stands for Capacitor Discharge Ignition. Capacitors do age and dry out therefore losing capacity and therefore store less charge to dump when triggered into the coil to make spark. Makes sense to me...

All of this points to a need to replace and update the CDI. There are a couple of companies that make replacement CDI's now and a third is adapting an existing fully programmable unit to work with the older Xt's. I will be testing one and can report on how it goes. If anyone is interested in this please PM me anytime.

I'll report here how my New Zealand unit performs as it may help someone else diagnose their problems.
