i got 4150 not 4510... was that a typo or did i get the wrong ones?
got the cops and harness in mail.
Got the wrong ones---4150's will open your vboost at 8000 rpm's----:bang head:

Just wanted to add a lil update:
So far, i've run across two types of Denso COPs. The type that the Hayabusa/GSXR's use work very well. There is another type that is a little longer and they neck down just before the rubber boot that sits over the plug(The Honda F4 and F4i use thes). These work well, but their length makes it harder to get on the plug. They both use the same electrical connector on the top. They are not a ton trouble, but personally i like the looks/ease of install/removal of the shorter type.
Here are the bikes that use the SHORT COPs(that i've found so-far):
98-2000 GSXR600 SRAD
01-03 GSXR600
98-99 GSXR750 SRAD
00-05 GSXR750
01-08 GSXR1000
99-08 Hayabusa(GSX1300R)
02-08 R1
99-02 R6
04-07 R6
03-08 CBR600rr
03-06 ZX6/ZX636(maybe the 07-up as well, just have not verified that yet)
98-03 ZX9
00-05 ZX12
06-08 ZX14
I found one set of R6 coil sticks that said they were 03 and they were the long type. Not sure if that was a typo or what. So, on the R6 coil sticks, i'm not 100%. Might be good to shy away from the R6 cops anyway due to the previously posted problems with some of them, at least on the 03-04 R6's.
These use the longer type COPs:
CBR929(all years)
CBR954(all years)
CBR f4/f4i
CBR1000rr(04-08)
98-02 ZX6
Looks like the wiring harnesses from ANY of these bikes will work on any of the coil sticks(long or short).
Just wanted to pass the info along. Hope this info is helpful.
I bet your pilot jets (fiche #42) are clogged. Your description strongly-suggests it. It's worth-it, learning how-to clean them, because having a competent shop do them will probably cost you several hundred dollars in labor. You are required to remove the carbs, and to-remove the float bowls, then the jet blocks, to do it. I suggest replacing screws with allen-head cap screws for the diaphragm cap covers for the CV slides, and the float bowls, at a minimum. A well-stocked hardware store should be able to furnish those.
Removing the carb blocks often will result in torn gaskets (fiche #35), so I recommend having those on-hand before the tear-down. You may get lucky, and be able to re-use them, but if you have them on-hand you should be able to remove, to clean, to reassemble, and to re-mount the carbs in a day.
An ultrasonic cleaner is what I find to work best for cleaning, one big-enough to do the assembled carbs together costs $$$. You can use the one Harbor Freight sells, if you split the carbs into two pairs. Take lots of pics to guide yourself in the disassembly/reassembly.
Usually the left front cyl is prone to becoming obstructed because of using the sidestand, and the migration of fine particulate material from a corroded gas tank, or bad gas. Because that's a low-point on the fuel delivery system in the carbs, the crud stops there. Does the 'dropping the cyl.' occur at idle, and off-idle, but not occur at the upper-half of the rev band? The temperature of the exhaust pipe using an infrared temperature gun would reveal a very-different reading on the cyl cutting-out, and would quickly come to temperature once it begins to fire normally, and then drop in temperature as the revs drop.
The pic is a pilot jet with a single strand of stainless steel wire being used to clean an obstruction. Might as-well check the float levels while you're in-there, it makes a difference in fuel economy and smoothness if they're off.

In my original post, I said it was the left two cylinders not firing right but I mad a mistake on what side was causing the problem. It was the right side giving me problems. I m very sorryleft
If you get an R1 COP set with the wiring harness, are the large & small wiring plugs plug for play? Or do you have to hack them to connect to the old Vmax wiring harness?I agree. The factory style connector is very well weatherproofed and has a lock to keep it secrure.
