carbi balance and tuning

[ls650]

Hi i am a new user i am also a new and proud owner of a 1985 R65LS. I have recently done a service on it, and since then i have noticed flat spots when accelerating and when taking off slowley in low gears. i was wondering does anyone knwo where i can get information on how to do this as i have the book for bmw twins, which covers my bike but does not give details on tuning or balancing carbis. Note i do not know much about mechanics but i am very willing to learn and try.

There are a host of tune-up items to consider, head torque, valve adjustment, advance mechanism operation. I suspect some here will advise a check of the carb diaphragm as well. As to balancing, well, that comes after all other considerations have been checked first. when your ready heres a handy little tool that I swear by.

There is every chance your carbs need setting up properly as flat spots at takeoff are common unless done so.
With all other things correctly set up (timing, plugs, valves), you balance the carbs at idle after setting the mixture, ensuring you have at least 1 - 2mm of free play at the cable adjusters. You then have to balance the cable pull on the carbs, which is where a flat spot can occur if they pull at different rates.
I won't go much further as there are plenty of info on how to on the net on how this is done, and for a newbie it's best to use a manometer like Rich suggests. It's hard enough showing someone in person how to do this without doing it in words, maybe one day I'll do one with pics and post it on a website I'm proposing to set up!! LOL
