spark

My understanding is that the last "ring" of the plug indicates the fuel mixture. By saying last ring I mean the last section of the male threaded part that the ground strap is connected to. Correct? Anyone have any specific info on how to "read" the plugs to make sure all is goo? I've...

Hi guy's hope some one can help. No spark since I replaced starter clutch. Found I had nipped the wire from the pickup coil. had this soldered together. still no spark. put test meter on the connectors and I am getting 95 ohms

Take a look at this article: http://www.cyclenutz.com/repairtips/bat_coil_ign.htm After reading it, does anyone know how our systems are setup? I never did the test myself, but I'll do it when I get my new TCI (my bike is currently down do to frying the Dyna 3000). I've never seen the issue of...

Re: May have found a cheap coil/wire replacement option I'm not quite sure I fully understand the hotter/cooler spark plug theory thingy. Could anyone explain this properly? Also, how do you find out which is the appropriate cooler or hotter plug for any given motorcycle? Can you tell by...

Does anyone think that these would work for the max, of course the straight ones. Or what mods would I have to do? http://street.parts-unlimited.com/6/388/6027415

Hey guys - I saw that Mark (maleko89) listed the NGK part number as being DPR8EA-9. On the Outlaw site in the spark plug article the number is DPR9EA-9. I understand the difference is that the #9 plug is colder. In ya'lls opinion is there much of a difference between the two? Since I'm in...

Ok, so my '86 Max has great spark on the front and will run on the front 2 cylinders. However, the rear cylinders have no spark when the starter is hit. Now whats really odd, is that they will spark ONLY when I shut off the key switch. I turn the motor over, nuthin. I shut the key off and...

I have an '86 I'm working on and early on determined the pick-up assy was bad,but after getting what was supposed to be a known good used part,the ohms readings on the used one were exactly like the one on the bike.The original tested @ 245ohms on three out of 4 pick-up leads vs. the 110-115 the...

Today I decide to take the bike out for a ride. I start it up and drive out of my apartment complex, everything is just fine so far. As I pull out on to the main road I accelerate through 1st gear, and as I shift into 2nd the bike all of a sudden just dies. All the lights work and the...

I have decided to get some wire from Kingsborne, but do not know which type to purchase. They offer Mag-wire and Copper Core styles. Below are the desriptions. The boots that I will be using have 5k resistance built in so using the copper core shouldn't be a prob, but I didn't know if the...

I searched the forum for "spark plug gap" and it came up with 104 threads. But none actually discussed what everyone's thoughts are on setting the gap. So I thought I'd throw this out there? I know the manual says the gap is supposed to be 0.8 to 0.9 And when you buy the NGK spark plug the -9...

I have been looking at the ebay listing for the red V-Max spark plugs wires for awhile and decided to make my own. I purchased 4 NGK spark plug ends from a local motorcycle shop, but cannot find any 7mm red spark plug wire to buy by the foot. There were a couple finda on Google, but mostly solid...

ok im haveing a problem at idle my vmax only sparks on 2 cylinders but the minute it gets over like 1500 rpm it starts to spark on all of them whats up with that? thanks for the help

I ran my 96 Vmax with Stg 1 Dyno Jet kit, K&n, Supertrapp 4inch with no pucks. i dynoed 98rwhp and 75 rwtq on a 50degree day. at about 6200rpm when the Vboost kicks in, the graph gets pretty unstable. any insight would be appreciated...

Hope I dont start some kind of war here.:whistlin: I have read up on the subject and there seems to be quite a bit of disagreement on whether or not a higher spark voltage is good or bad. :confused2: Just wondering what the experts here have experienced. Reason for asking is wanting to get...

I have a bunch of spark plugs that got fouled when I had problems with my carbs, I got some of the black off, is there a solution or product that I can apply to clean them. Thanks, Ron :ummm:

Hi folks, I just installed my new HMF on my 06 max, it has 100 % STOCK carbs, with a K & N replacement filter. It seems to run fine. However I am unsure if she is running rich or lean...it''s really hard to tell ...so I snapped a picture of one of my plugs for all the Carb Air/fuel Guru's out...

Yesterday, the max run fine.....went to work.....back home.....no problem! TODAY....took the car, after work came home to take the bike out......went to start it.....just cranked and cranked. I pulled the plugs.....cleaned them.....tried again....NOTHING... (crank but no start!) I put another...

Just called the Yamaha dealership and they only sell wires WITH coils for 360.00 a set. :rofl_200: Anybody have an opinion on this item for sale on Ebay in regards to satisfying my spark plug & wire woes? Actually are the spark plugs even included...

What is a good "hotter" plug to run?
