Thanks for taking the time to read what is one of the most posted questions on the internet regarding 1200 Bandits? (possibly)
Bought the bike recently after a 3 year break and im so happy, the suzuki engine is amazing. This is my third one.
When I test rode the bike all seemed well. After a week I found the carburettors needed balancing.
Balanced the carbs and found there was a 1000-3500 rpm flat/wobble spot while under load. So I raised the needle to the second clip and while things are better the revs through the 1000-3500 rpm range are erratic. So as I approach the apex of a bend with a closed throttle and open the throttle there is a serge in power at the apex that cannot be predicted. The idle is also alittle rough and if you open the throttle while in neutral the revs rise as the throttle is opened, if I then keep the throttle where it is the revs will slowly then increase. Choke is a nightmare but since I raised the needle the bike doesn't stall under breaking. If the bike idles for along time at a set of lights it becomes very difficult to regulate throttle and seems to "bog down".
Bike has an Art rear can, has been "dynojetted" and has a K&N filter in the standard airbox.
I'm going to look at the carbs this BH weekend. I'm thinking of a clean concentrating on the pilot jets, mixture screw settings and float bowl heights, while changing the air filter and needle height back to standard
Any more idea???
