Posts: 2041 Cumbria,England Gender:	Spark plug 11/02/04 at 03:22:59 I'm going to go on about spark plugs again, strongly reccommended is the iridium if you can find/afford one, if not platinum comes a close second. They can be gapped at max std or + 4 thou and will give better starting,response,torque and power. The down side is the price. I got mine for christmas last year !!! Clive W

Well, okay. I've decided to try some different "things" this winter. My general rule has been to do what I know works, but others seem to think some (unproven to me) products are beneficial. So....

I will explore the use of some of these "performance" plugs. I don't have any reason to expect any difference, but a new plug can't hurt. So why not? If you recommend it, I'll give it a go.

As well, in the 4 years since I experienced clutch slippage with synthetic oil it appears that more and more manufacturers are producing oils that clearly state compatibility with motorcycle wet plate clutches. That was NOT the case when I last tried it. So this time around, I'll try that again too.

I already have new filters anyway.

I just went out to www.ngk.com and the appropriate NGK iridium plug for the Savage is the DPR8EIX-9. I was planning on changing my plug out and adjusting valves sometime in the next couple of months, so I thought I'd try the iridium.

They better work, or there'll be 2 of us doing a little "Kaw tippin'" in England, I think" Grin

They have a Spark Plug 411 that is pretty interesting. The iridium plugs I ordered were $6.95 each.

Iridium? $6.95? Don't sound like a bad deal to me considering that you only change plug once a year, max. How many ground electrode does it have? The easiest path to ground is the one of least resistance, so if a plug has 4 electrodes any one of them will be the path of least resistance but not always the same one, consequently having the optimum spark at all times.

It has a single ground electrode and they cover that topic too, though they state multi-ground plugs often perform worse than others unless in an engine designed specifically for them. I don't think I've ever actually seen one in real life but I've never worked on anything but fairly basic engines either. To that point, I'm so easily impressed that when I spent some time one summer as a teenager working on Mac trucks, I thought glo-plugs and timed fuel distribution (vs spark distribution) on a diesel engine were just neater 'n hell. I still think it's kinda cool.
