Yorkshire rider 1993 Posted April 2, 2019 Share Posted April 2, 2019 I've got a 1999 Suzuki bandit 600 gsf and when I put the fuel petcock on reserve my bike starts sputtering and losing power, could this be caused from water in the tank as it only happens when using reserves? It still idles fine but when I set off and revs are applied the exhaust makes a belching sound and I have to accelerate really slowly or the engine gets no power. Could do with advice on where to start looking for a solution. Quote Link to comment Share on other sites More sharing options...
Tiggie Posted April 2, 2019 Share Posted April 2, 2019 (edited) The fuel in the reserve tank can get contaminated with bits of crud, rust flakes etc as it all goes to the bottom. Inside the petcock will be a fuel filter, sounds like the reserve filter has got some debri blocking it.the long bits sticking out are the filters, the longest one being the reserve one (no its not, its the short one!

Guest Richzx6r Posted April 2, 2019 Share Posted April 2, 2019 Could be shite in the carbs or the reserve outlet from the tank could be slightly blocked Quote Link to comment Share on other sites More sharing options...

Yorkshire rider 1993 Posted April 2, 2019 Author Share Posted April 2, 2019 Yeah I thought it would be something like that, just wanted a second opinion, I don't think it's a carb problem as it runs fine normally, and I recently cleaned the carbs and changed the spark plugs, how would you recommend cleaning it or should I just replace it with a new one Quote Link to comment Share on other sites More sharing options...
Guest Richzx6r Posted April 2, 2019 Share Posted April 2, 2019 You should be able to remove it from the tank unless I can be corrected? Quote Link to comment Share on other sites More sharing options...
Yorkshire rider 1993 Posted April 2, 2019 Author Share Posted April 2, 2019 This may be a daft question but should I drain the tank before removing it? as I'm guessing the fuel will piss out otherwise Quote Link to comment Share on other sites More sharing options...

You could stand it on end so that the fuel level is below the level of the tap . Quote Link to comment Share on other sites More sharing options...

kingmunky Posted April 2, 2019 Share Posted April 2, 2019 Aftermarket in-line filters on these bikes can cause issues as well, they weren't fitted as standard to earlier bikes and you haven't mentioned if there is one. But, if there is, I'd start there. The point at the top about crud blocking the petcock filter is a good one too. Quote Link to comment Share on other sites More sharing options...
fastbob Posted April 2, 2019 Share Posted April 2, 2019 Although this should affect both ON and RES positions on the fuel tap , while you're at it it's still worth checking to make sure the vacuum pipe isn't kinked . By the way does your bike run ok on PRI ( Prime ) position ? Quote Link to comment Share on other sites More sharing options...
linuxrob Posted April 2, 2019 Share Posted April 2, 2019 Am sure the 600 Bandit has an inline filter, would start just by draining the carbs one at a time to see what you get out. Saying that i do clean my tank out on my 1200 bandit every year. Not a difficult job, do not over tighten the mount screws. You will probably find sediment in the tank, rust mainly.Rob B Quote Link to comment Share on other sites More sharing options...
