So those white pole doodahs were ceramic resistors ? Neat. What was the plug cover part numbers you requested ? What was the resistor value ?
Cheers Simon

Got a set of these Simon:
http://www.ebay.co.uk/itm/230778918900?s...1439.l2649 Darrsi on here was that fella that linked up first, but he and a bunch of other people have used them now. BLoody good news so far, I ran the bike a bit before swapping them over, as to be expected now it had a lumpy idle, and wasn't revving right (dropping cylinders); Old HT leads off, fitted these, fitted them back on the bike, it fired up first stab of the button (well actually it didn't, but I'll get to that in a second), and within a couple of minutes had a bloody nice strong steady idle! Did have me confused for a bit though, I had the coils back onto their bracket, with the caps on their respective spark plugs. Tank back on, attached that all up and tried to start the bike - no go. The engine was spinning, but it just wasn't starting. Of course after a couple of highly confused minutes, I remembered it would probably help if you connected the coils back to the loom! :rolleyes  (31-07-13, 01:21 PM)simonm link Wrote: So those white pole doodahs were ceramic resistors ?

You can always buy original spark plug caps.......only £52 EACH :lol http://www.yamahamotorcyclespares.co.uk/...AL+1&uID=0

Do you think the NGK caps would be considered as better than OEM or not ?
NGK are extremely well known for spark plugs and caps, would they produce better stuff than Yamaha or whomever makes it for Yamaha ? I think I might have to get some NGK iridium plugs and caps for the next service. Although, as an aside, the bird on page 2 looks even more mad than hot. http://ngkntk.co.uk/wp-content/uploads/2...le-Cat.pdf

I've always put iridiums in every bike I've owned, I don't find a massive running difference but they definitely make startups a bit easier (although admittedly that may be because they're new, rather than specifically because they're iridium), but they also last for AGES, which makes them a lot more cost effective than usual plugs! the caps are definitely better than the genuine yam ones I had - but then you'd seen how loose mine were! The seals on the NGK ones though are definitely tighter than the Yam ones (as in where the wire physically enters the cap, I don't have a gap any more so no more water ingress). To be honest at a tenner for the set, I don't really think you can go far wrong! And Darrsi, that is absolutely mad, Yamaha must just not want to sell any spares at that kind of price!

I'm guessing the Black is exactly the same apart from the colour ?

[/quote] I actually think that Yamaha don't want to be selling spares for older bikes. They'd much rather you went out and bought a nice new model, and sell you spares for that (maybe at a slightly less extortionate price!). Always used NGK products, always at least as good as OEM, if not better.

Well been out for most of the day so far on le bike, and I think I can safely say the issue has resolved itself - not a single misfire anywhere, even when I deliberately tried by opening the throttle fully from about 2k revs. Job's a goodun! Big test will be next time it rains, fingers crossed the plug caps do their job as they should!
