So I have to confess... I've never sync'd the carbs on my XS before today.
It seemed to run fine when I awoken it in 08 so I figured "leave it alone" (and let the brow beating begin 
)
I pulled out my brand new 4 gauge sync kit. got the bike warmed up and then hooked everything up... WOW
maybe I should have done this awhile ago.
Got it all synced up, reset the idle speed, adjusted the mixture by ear, re-synced.....
BTW I pulled the timing cover off... tamper proof screws still there. Timing still dead on
On the advice of everyone about fuel octane I decided to investigate. Pulled #4 plug and got the bore light and scope out. Rolled the motor till I could see exhaust valve hanging. Inserted bore scope and light. Yep I'd say there is some carbon in there
Poured 6 ounces of seamfoam into a seal container and head to the gas station. Got rained on between my house and the gas station, which is only like 2 miles away. (f'n april showers) poured seafoam in tank and toped it of with 76's finest 87 octane regular

Took a 50 mile cruise around the extra long way home (got rained on again) Got home and pulled a few plugs. Theres carbon now showing up on the ground strap and outer ring... So the seafoam and lower grade gas are working its way thru... Plug still read a little lean. Right now I'll atribute that to the fact it was 51 outside with a feels like 45 plus we've had T-storms roll thru today so the atmospheric and barometric pressures are all messed up right now. suppose to be 60 and sunny tomorrow, gonna take the wife for a ride. Will report back after that.

I didn't know I was missing you but I'm sure glad I found you!"

fixed that real quick, can't have that. I'll shoot video tomorrow and post it on here of the bike running with the sync gauges hooked up and going. Then I'll post some pic's of the plugs after the ride. we will see if I did good
