Fine in the dry but got rained on this morning and it was spluttering like it was running out of fuel, managed to keep going to get to work, dry on the way home and it was fine - Bandit 400
was initially thinking a fuel problem but as it was fine in the dry then me thinks it was the wet stuff.
whats the best thing I can do to to waterproof the eleccy bits?
sounds electrical.
Water in the kill switch?
Water in the side stand switch?
The kill switch area has been apart recently.... Might need some sealant and grease applying.
drained some water from the air filter and had the HT leads out for a clean and check, they look like the originals and the seal around the top of the plug area was poor, there was also some grit on one of them so water would have gotten in easily.
I put some rubber around the HT leads where they touch the frame to see if that helped but still the same this morning, think I will start replacing stuff.
Thanks for your suggestions, I will add all of them to the next maintenance.
Silicone spray of most types will repel moisture.
Had trouble starting this morning as the starter turned over slow, it cut out a couple of times when I pulled up and when I stopped for fuel I had to bump it again as power had drained. Made the call to return home as lights were dim and I would have had to ride in the dark later.
I thought last night that there was a flickering of the light as I put the bike in the garage...
So either Battery is duff or - more likely - reg/rectifier is screwed, will have a play with a voltmeter later to see if i can narrow it down. Just ordered new plugs as well....
my son luke had a bandit 400 which didn't like the wet..i told him to keep engine running when he reached his destination which helped to dry out plugs area and so would be easier to restart later.eventually we changed the plugs and he had no more trouble..possibly moisture causing old plugs to arc out..
Could be carb icing?
Fixed it, not sure if the wet splutter has gone away but got it running again. The regulator rectifier had broken as after recharging the battery and started it had standard 12v across the battery. Did some research after looking at the £55-70 price tag and others had fitted a cb400 one for £20, just got to cut the wires from the old one and get the connectors in the right place. If it doesn't last then i will buy a matching one.
Think i need to clean all electric connectors, is there a good spray that will prevent water getting in or coat things to stop corrosion?
bandit 6 and 12 have carb heaters not sure of 4's would think they have as its been a mod since the 80's after some problems with running at speed.
would really have to look at your fuel, could be rain got under fuel cap ( drain hole plugged up) and its got in to carbs
