Umm... is this good or bad? -- jeremy '02 Fazer 600 in blue _______________________________________ jeremy at hireserve dot com
Thanks Rog, I've got to sort my bike out before I go spending out of phones and stuff at the mo. Cylinder number 2 is playing up a little, I think it may be an inlet valve or something that's a bit knackered.

Well, it is similar in approach to that taken by one of the US bike mags (I forget which) in their "Torn in the USA" article of about 15 years ago. They backed test specimens of various materials with a sack of powdered chalk, and dragged it along a road surface. When chalk appeared, they measured the distance travelled. The further, the better, obviously. Nothing wrong with it as such, and it does provide an indication, but knowledge and testing has moved on since then. Some fabrics will fare quite well in a drag test, but the initial impact in the EN 13595-2 test defeats them almost immediately upon contact; which is it was developed and then chosen for the standard, in preference to other abrasion apparatus such as the Darmstadt, Martindale and Taber machines. There is information on the Darmstadt machine in the BMF PPE briefing document (a hyperlink to which appears elsewhere in this thread). The Martindale replicates less aggressive abrasive effects, such as that between clothing fabrics and upholstery, so is more concerned with durability over long term wear. The Taber device cannot test multi-layer constructions, so can only give single-layer data. With "laminates" in clothing, as in other fields, the performance of the whole is greater than the sum of the parts, so using a Taber device wouldn't have helped at all with the developments in CE textile motorcyclists' clothing which have taken place over the past few years. So, I wouldn't wish people to misunderstand and think I am criticising Draggin' Jeans' approach, because I am not. It provides a useful indication and, as was said earlier by another contributor, it took some faith in the product for Grant Mackintosh to do what he did. My view is that, like Shoshoni Jeans before them, perhaps these and similar products (e.g.: Hood and Giali) currently occupy a hinterland somewhere between "caveat emptor" and "Conformite Europeen". Legally, they are the former, but it *might* just be possible that they could squeeze into Level 1 of EN 13595. We'll know for sure when we see the CE mark on one of them.

Whilst I have to admit that a practical demonstration is A Good Thing advertising wise, I have seen too many cowboys pulled along through cactus groves on their arses over the years to know that Hollywood is good at what it does. That was me said that that was. See, now, if you remembered to put in some attributions you wouldn't be having this problem. About right I reckon.
I checked that last week, all was ok on that count. I checked the carb float heights too, only one was out about 2mm. I noticed the other day[1], that one exhaust was cooler than the rest, number two to be exact. Maybe it's as simple as a coil fault, or a knackered plug. I'll start by checking the coils with a meter I think. [1]After starting and ticking over for a few minutes.
I thought you would modestly prefer not to have readers reminded of the gravity of an Auvache proclamation. ;-)

It's less pronounced when it's hot. Maybe I'll swap the coils round, and see if the fault moves too. I'll try putting a new set of plugs in.. Then it's on to the carbs to give those a closer look.
Muck says... IIRC on your bike each coil fires two cylinders, so I'd doubt the coil itself was the problem. You'd find the other cylinder fired by that coil would be exhibiting the same symptoms. I'd check the HT lead/plug and valve clearances before anything else. It sounds like a lack of compression or lack of spark on that one cylinder.
Clearances checked last week, maybe it's a plug cap or lead that's knackered. I'll throw in a carb ballance too, just for good measure.
Not necessarily glasshopper. Failing coils can fire one cylinder ok, but fail to recover well enough to give full whack to the other.

Champ says... Wasted spark principle innit? As Champ says each coil fires both plugs at the same time, so the other cylinder will exhibit the same symptoms.
