Well i went to do my sync today but it made little difference as i couldnt get mine to equal. Anyways, here's a short How To with a few tips which the other threads don't show you.
First off, remove the seat, both side panels, lift and prop up the tank. (you could actually skip this step!)
Front TB vacuum nipple can be accessed from the left side of the bike under the tank. this point towards the back. See below where i have already attached the black rubber hose from the gauge.
On the right side of the bike between the carbs, youll find a black round canister held by a rubber sleeve, pull this backwards to slide it off the mount so you can move it out the way to access the Rear TB nipple.
Rear TB vacuum nipple can be accessed on the right side through the triangle engine mount. This points forward. Mine already had a small piece of rubber blocked with a screw.
Now to locate the sync adjustment screw, this is on the Front TB, and has a rod going to/from both TBs. The rod is the top on and on the end of it, youll see a screw on the front side.
The sync screw is accessed on the right side, just in front of the triangle engine mount and behind the 3 fins on the bodywork. Just pull it back. This screw is a pain to get too and adjust with a screw driver, as its under the airbox. I also tried the long nose plier method used by the other forum, but its far too difficult and takes far too long and too many turns. Its so easy to slip off the screw head, so here's Kevs solution.
Get a small section of rubber hose, i had some stretchy silicone hose 3mm dia.
Slide the hose over the top of the screw, which you should be able to reach by hand. Now you have something to grip and turn.
Mine turns by finger without any issues, however, my adjustment just wouldn't come together.
My bike originally started off like this.
No matter which way i went with the adjustment, i couldnt get it any better, so gave up for now.
Next time i do this, i don't even think i need to remove any panels, as i know where everything is, i can get to it with my small hands.
