raesewell Posted May 28, 2019 Share Posted May 28, 2019 I have an idea, it doesn't like water, it's a bike not a submarine Quote Link to comment Share on other sites More sharing options...

Fev1983 Posted May 28, 2019 Author Share Posted May 28, 2019 water getting in through the air filter, Can I stop that happening or is it just one of them things that happen with heavy rain??? Quote Link to comment Share on other sites More sharing options...
dynax Posted May 28, 2019 Share Posted May 28, 2019 No idea, i guess it depends on the position of the filter, you could maybe put a slightly bigger plastic box over it, leaving plenty of gap for airflow, but help reduce direct water contact, Quote Link to comment Share on other sites More sharing options...

winston smith Posted May 28, 2019 Share Posted May 28, 2019 Could also be electrical - water splashed up onto the HTs or plugs could cause shorting/arcing and the misfiring. Quote Link to comment Share on other sites More sharing options...
Stu Posted May 28, 2019 Share Posted May 28, 2019 The bandits are fairly open and with the heavy downpour my guess is that a bit of water has got on to one or two of the plug caps causing it to run rough Quote Link to comment Share on other sites More sharing options...
Tankbag Posted May 28, 2019 Share Posted May 28, 2019 I sprayed ' dampstart' around my plugs to stop this happening on my b12 Quote Link to comment Share on other sites More sharing options...

Tankbag Posted May 28, 2019 Share Posted May 28, 2019 On a bike like the Bandit I'd agree, I've ridden 100 miles in atrocious weather on my faired bike with no issues Quote Link to comment Share on other sites More sharing options...
fastbob Posted May 28, 2019 Share Posted May 28, 2019 Definitely time to think about replacing your HT leads but beware ! If Bandits have the same stupid little clips attaching the leads to the coils as an older GSXR then they WILL snap ( trust me on this ) . They will also be very hard to find replacements for and very expensive . Quote Link to comment Share on other sites More sharing options...
iangaryprice Posted May 28, 2019 Share Posted May 28, 2019 I have a GSX600F which has similar engine to your Bandit.It used to run badly in heavy rain. missing stuttering etc.I removed the tank to access the ht leads. Cleaned the plug caps and rubber shields in the cam cover. The HT leads seemed to long, touching too many parts of the frame, so I shortened them to get better runs clear of anything metal where possible. A clean end to the lead also givesa better connectionot the plug cap. I didn't need to replace any leads, those clips do look flimsy - as stated above.Where I couldnt keep the HT leads away from metal I cable tied sheet rubber (about 1mm thick) to the metal frame and crossbar to give an extra layer of insulation.Since I did this it has been much better in rain.
