HELP!!! Can anyone give me some kind of answer to this annoying prob I'm having with my bandit??? Recently I have been getting loss of power then a surge back to full power , this started at the low rev end 2000 , and is now affecting 5000 revs . The power loss is so severe now on a lean into a roundabout I lost power and nearly ended up under a lorry . I have cleaned the carbs , checked breather hose , fuel line not snagged , blew out fuel filter . Yesterday she started to back fire !!! Any help would be appreciated . Matt.
Hi you said you cleaned the carbs. I take that to be strip down and clean out the inside? Are they vacuum carbs with a rubber diaphragm? if so check for pin holes in the rubber.
Yes they are rubber diaphragms and plastic floats , will have to restrip them and forensic examination, on reading other forums this seems to be quite common on bandits , I've had 3 and this is the first time I've come across this, every forum I read nobody actually says they have definitively found the problem . Cheers guys . Matt
i had a similar problem on a 125 bike, it turned out that air bubbles in the tube above the petrol tap was the problem try running the bike on the reserve tank as this does not go through the tube
