Hi, I'm new to the forum, and newish to riding after an extended abscence. I have a 2002 Suzuki GS500E with 45K on the clock for commuting to work. Recently the bike feels jerky and unstead, especially at low RPM (3,000-5,000). Its quite subtle, so much so that im not 100% convinced there is a problem. But things just dont "feel" right. It feels like the a) engine is missing, but the rpm needle doesnt dip, and it idles nice and is not so apparent during acceleration. I just get a feeling of constant dipping on the front shock. It also feels like im cornering wider now, and its unstead on the lean. It seems to be ok at high speeds on the motorways. Funnily enough, it seems to have occured after I took the girlfriend for a ride around the block. Its the first time ive taken pillion on this bike. She isnt a behemoth either, quite the opposite (50kg) but I do recall a pretty significant slump when she got on. More so than I expected. But I havent riden for AGES to compare. The front suspecsion seems to be in good order, but im not certain how to check the rear. The chain has good tension/slack (1-1.5 inches or so and is lubed. I changed the spark plugs to be sure. Tires are good. Steering seems fine. Any suggestions? Should I just accelerate more?
