coils

My 02 vmax has 3 cracked coils seems to run great also noticed when i removed the nology wires to get repaired that the 1 coil was corroded pretty bad as well as the wire,Should i replace the cracked coils? JIM 3933

I have had a set of nology wires on my vmax and noticed no changes in performance,but i see on ebay they are selling the nology coils to anybody have these. I did notice that i have a coil that is cracked but its still working. JIM 3933

Anyone know anything about the msd I coils for the max? What is the best value/performance option for replacement coils? :ummm:

Hello Recently switched to COPs and I now have four ignition coils in excellent working condition. I listed them on ebay for $25 each (seemed appropriate given other auctions) but got no hits. Anyone have any idea what they are worth? Anyone else in dire need of replacement coils? PM me...

Did the test as indicated in the book (for an 88) but I'm getting 3 readings at 230 and 1 at 110. According to book all should be under 126. I happen to have another alternator cover I got on ebay with pick ups and i'm getting the same readings..what's wrong here?

Hi All, A while back Mark (birdoprey) mentioned coil choices using the Haltech ECU. Popular coil's used with the unit are the GM LS1 and LS2's. He also mentioned that LS2's have their own heat sink and we're real flame throwers. Something I need for the race bike running methanol. Sooo I...

How cracked does a coil have to be before you would recommend replacing it. When inspecting my coils I noticed a hairline crack in one that does not seem to go right through the casing but it is hard to tell. The ohm meter shows proper reading but I was having a sudden stall issue that seems...

I'm changing out a bad pick up coils, but you can use the steps below if you need to work on your starter clutch, flywheel, stator or slave clutch master also. First put your VMax on a work stand or center stand. You can lean it to one side if you want to minimize the oil loss. The...

Ok so i got my battery up and going after a full night of charging. I started taking apart the wiring harness tape to find the crimp underneath and i noticed there are two fine stress cracks on the underside of my coils under the seat. They are not deep just white cracks. I will post pics later...

On the left-hand side, I made sure that the COP wiring (arrowed) was in front of the V-boost servo, so it wouldn't get in the way of the V-boost cable or cam movement: the wiring is routed through the opening in the heat shield (arrowed) that the HT lead used to go through: Now the left...

Ok so back to fitting the COPs, finally. Here are the front wires prepared - notice that the #4 wire has to be longer to reach down to the right-hand cylinder from the connector on the left which is pretty close to the main harness: Here's #4 connected... ...all taped up... ...and fed...

To remove the front coils, the only way to access all four coil mounting screws is to move the bracket that hold the CDI, ignition vacuum advance unit and V-boost servo. Here's a full view of it; the blue arrows shows the #4 coil screws, and the red arrows show the bracket mounting screws (x4)...

As I went to do the front COPs, I thought there was no way I would leave the original coils in place - after all the COPs mod is as much about saving weight and space as it is about better performance through less resistance in the coils circuit and better reliability through removing those...

Ok so since I couldn't ride today (missing that front wheel spacer) I went ahead with Birdoprey's Coils Over Plugs mod. Thanks for sending that wire harness Mark!:worthy: I got a set of COPs from an '05 GSXR 600 ($10), and another set from an '01 CBR 929 RR ($5) as spares - both ended up being...

Here is a pictorial of the install for Birdoprey's COP's . I apologize for the poor pic quality and the layout. This is the only way I know how to set it up. There are 10 pics, Numbered from the left, top row-#1 - #6, bottom row #7 - #10. #1- COP and wires with crimped spades #2- Factory...

hi,im new to this site so please be patient.i know ye guys have probably discussed this topic over n over but im doing a much needed re build on my 93 vmax (been abusing it since 94)and its turned into a bottomless pit as far as money is concerned.where do you stop? i have taylor leads,dpr9...

I just finished testing the 4 coils I got from Pinwall and 3 coils Morley sent. I also just tested a set of p/u coils from Morley. I'll post the results of everything: My '85 (on the bike) pickup coils: B-O: 119.9 ohms B-W/R: 120.4 ohms B-Gray: 121.6 ohms B-Whi/Green: 120.5 ohms Morley's...

Hello All Ok here is a copy of the last post. I just boought a 97 vmax. Stock box & jets. Kerker 4 in 2. 9900 miles. Problems: 3000-4500rpm blog...Fixed thanx VMAXFORUM! Rusted gas tank & trash in carbs. New filter, new tank. Cleaned fuel pump & carbs. Carb sync. Oil & filter changed. FRAM...

I did a search for "nology" and "coil replacement" sorry if I missed it. So I have three cracked coils, not bad- but not like they are self healing. the dealer price on the stock coils is higher than a set of nology coils. I know I read about another replacement here on the forum as well. I...

After a long, long, cold winter for the max parked out in the detached garage this winter, while replacing out the battery on the max, I notice both rear coils now have slight cracks to them. Did the "cold" temps this winter cause this or? Could it be that short 10 amp jump start I did with...
