well, just went to go home and she refused to start. She started fine this morning, now after 4 hours of cool down she refuses to start with a bit a backfire thrown in too!
How do I do that check to test the generator again? Its a nearly new battery.... Bugger!

Okay! its started after I cleaned to plugs! Brilliant! Now all I need to do is sell it and buy a mint rd350 lc..........
Anyone want to buy a nice duke 750ss??
Told you it would start. I think your plugs are fouling, causing the starting problems.
Fouling can be caused by a number of things such as mixture, however from your previous posts about the charging system you may have a weak spark that can result in plug fouling.
As I have said before, take your bike to someone who can give your machine a damn good service and get all those little niggles sorted. Summer is on the way and you don't want it to let you down.
You got the bike for a good price because of these niggles so I don't think you can complain if you have to spend a couple hundred getting it sorted. You wont regret it, but you would if you bought an RD!:roll:

Hey! I had an Rd before and loved it! oooh it sounded so pretty with allspeeds on!
Ive got me a volt meter now so I'll check the battery when I have her up and running tonight. also got her hooked up to an optimate, so that should help starting in the mornings... does anyone else run one?
run one ????????????:puzzled::puzzled:

I ran an optimate on my 750ss but winter months just made starting a problem. When not ridden for a week or so, even with optimate, the battery was just not up to turning all that mass running in lovely molasses (well, 15w isn't molasses, but you get the idea). Once things warmed up, the bike fired up right away with the same battery. Oh yeah, the nice cold soak also effect battery output. Optimate saves your battery, but doesn't insure winter startup!
If you're suffering plug fouling, try the Iridium plugs. They have a much smaller spark point and tend to be better self cleaning.
solved problems on a few 600's with them.

you can also change the heat range if you are careful. Used to foul the rear plug and went up a little hotter ending up with a nice chocolate brown instead of a wet plug. Course, Nelly may have a better solution!

Hmmm, these are a good suggestions....
Must fix the rgv first, then Ill be onto the duke in no time...!
Paul,
What plugs are you using?
NGK DPR8EA-9 are what you want to use. These come pre-gapped at 0.9mm (.035") which is a a lot more than the factory spec gap of .024" (IIRC). The ignition system is well capable of firing the wider gap which helps prevent fouling. I ran these in my 900ss for 5 years and never ever had difficulties with starting or plug fouling.
