Hey guys, The GS500F's been running pretty rough lately, and I'd rather try to fix everything myself (or at least as much as possible) rather than get ripped off by the mechanics. (I used to own an FZR and it cost $400 to get 'carbs cleaned' which wasn't even the problem in the end) So before I start, sorry for any ridiculously dumb/noob questions but I'd rather ask dumb questions then cough up dough, and please appreciate that I want to do it myself! First, some background info... It's done 26000kms. I've owned it since August last year, but went overseas for 4 months and left it in the garage. Left it with a full tank of fuel so rust wouldn't get in there. Came back around Christmas. Now here's the potentially dumb part - I pretty much got back to daily riding without doing so much as recharging the battery. So before I even start, I'm guessing this could be a factor in some of the problems I'm having. Commute with it to work and uni, averaging around 60km a day often in heavy traffic (Victoria/Parramatta Rd peak hour anyone?) So firstly, the bike pretty much won't idle, even with choke. The only way is for me to hold the idle at 1500ish rpm at the lights. If I let the throttle go, it'll die. Maybe dirty buildup in carbs from the 4 month hibernation? Any other possibilities for this? The bike also feels extremely sluggish - it struggles to accelerate. A lot of the time I can't even beat cars lol (shameful!) Secondly... when I start from a stop, as I let the clutch out, instead of the revs coming back down to normal, they stay up at higher revs (as if i was still feathering the clutch) for a few seconds before coming down. Also, occasionally when I am in say 3rd/4th gear at midrange RPMs, adding just a tad more throttle will make the bike rev a lot higher than it should be doing. More occasionally gears will slip by themselves, like from 2nd to neutral and more rarely, from 5th-4th etc. I'm planning to do an oil change tomorrow (need to get something to catch the old oil) which I am hoping will somewhat address the clutch issues but someone mentinoed I may need new springs/fibres. Also, is it normal for the clutch lever to have a tiny bit of free play? Thirdly, a recent problem. The chain was extremely slack (touching the top of the centre stand lever) so I adjusted that myself. But since then, there's been a strange noise on rotation of the wheel (sorta like if the brake is touching the wheel on a bicycle). Could I have tightened the chain too much? I've left about an inch of slack. I've also checked for anything touching the wheel and can't find anything. Also for checking the straightness of the rear axle, I simply measured the distance from the nut to the end of the screw... is that accurate? And finally, this may not be a real issue but I only get about 200-220km before I hit reserve. I use 91 fuel, none of that 'OMG ONLY PREMIUM IN MY BIKE' crap, and I'm very conservative in my riding. It's just that I read about some people getting 300+kms out of their GS500 tanks. Anyway, thanks heaps in advance hoping I can get the bike running prime again!
