I'm no expert by any means but trouble shooting 101 tells me that if the bike ran good before you did anything and you said it did, then look at what you did for any new problems.
Anotherwords, the pipes are changing color, you get popping and power surges but all you did is mess with the sensor and timing, then I would hesitate to mess with the jetting. Atleast until you can see the timing marks in the window and know that is totally correct, and have tested the voes.
BTW: Blue pipes equal lean and golden brown are rich. atleast what I have seen. Not sure what effect timeing has on them but since too advanced make it run hotter just like lean conditions, I'd assume they would blue from that. And I guess the reverse is true for too retarded. Anyone know for sure?

Thank you for your response Doug.
I wish I could go back in time before this mess all started.
The bike was running good but there was some question in my mind about the timing due to starting, popping and deceleration backfiring. I modified my carb (went to a 46 and 185) and that did improve things but the nagging problem kept bothering me.
I decided to get into the cone where the timing sensor plate was and make sure my timing was dead on. In the process I broke one of the studs that secure the plate in place and that opened an entire new problem in that I am in China and there is no such thing as a dealer near by... I ended up taking the cone off and drilling out the broken stud. That created a larger hole so I eventually had a new stud machined and a matching sized hole tapped into the cone.
This was fine but then the fastening adjustment slot in the plate where the newly machined screw needed to go was too small so I used my Dremell Tool and worried that slot large enough to allow me to install it with the newly machined screw as well as give me the adjustment leway I needed.
During this process I found on of the exhaust studs was missing and the one exhaust pipe was loose and leaking. The is problem ended up being the reason for all of the search and repair (destroy?) in the first place but by this time I had this mess in the Sensor Plate cone area.
After buttoning it all back up I was never able to even see the timing marks in the view port despite various plastic view plugs I have obtained from various sources. Also at this point I was not able to do the Static timing test as I was waiting for the Deutsch connectors to make the test harness. (Which I now have)
Not being able to get anything working just right and afraid my timing was really off I stopped riding the bike and waited for the new Sensor Plate and VOES valve I had ordered from the States.
They arrived day before yesterday and that led to my previous post about the Static timing problem.
So as you can see, with the stud breaking and so forth I can't go back to the original set up, no matter how much I would like to.
Cheers...
