removing coils for on wire coil?

[eye-p]

Cool. Thanks!

[Cutaway]

Not trying to be picky or anything but, there are 28.35g in an oz. So if my math is correct 272g = 9.59oz = 0.6lbs. Just thought I would clarify that!

Doh! I must have taken a left turn @ Albuquerque! Sorry about that guys.. you are correct sir 272g = 0.599657353lbs

What is the peak voltage of the coil itself, as in spark energy?

Jason... BOTH the HRC & OEM Manuals for RC51 & CBR1K rr put the Primary Peak Voltage @ 100V minimum .... If you want to do this get a hold of me off line.

Hey Guys,

FYI...
Last night I removed my front coil and weight it at work on my digital scale today,
My "front coil" with both mounting bolts & spacers weight 306 grams or 10.80 oz.,
I'll remove and check the rear coil in acouple days... I don't want to get too far ahead of myself, as I am waiting on
My RC51 "Coil mod. Kit" from the man that took this idea and RAN With IT, Scott! I also tested First:
cutting 1 of my "Old Spark Plugs" to size and then threading it this morning,... No problem cutting it to Size BUT I can see these being a pain in the arse, money wise with breaking the core(s) very easily...

So anyway, I'll be cutting my supply of S/Ps, 3 "9"s and 1 "8" tomorrow... so I'm waiting on you Scott

Thanks for these ideas boys "metalscorpio" an cutting the S/Ps to size "CBR400RR"

FWIW, the main reason I choose to do this "Coil Kit mod." is to clean it up alittle, "it" being the engine compartment and sub-frame.

I Hope this Helps someone,

Peace Jeff

I forgot to weigh those parts too, good job.

So the stock setup is 21.6OZ and the new coil kit I made is around 4OZ each so that is a good weight savings.

You guys rock. Finally something new to try. Don't want to high jack the thread, my apologies if I do, but:

Scott-

Will you sell sets of the turned plugs?

Which ones are in your kit, IFR8H-11 or IFR9H-11?

Anyone-

What's better to run the 8 or the 9? Maybe a combo?

Has anyone thought of possibly running two different heat ranges for the front-back cylinder? Would there be any benefits since the rear cylinder tends to run hotter? Flame on!

I can do either but I IFR9H-11 in stock and it would be $40.00 for a set shipped unless your in Ca then there would be tax on the plugs.

My pleasure and thank you Scott for taking on the cutting down too.

I have other ideas but for right now i'm just going to ride the bike the way it is as a control rider for NYsportbikeclub.com and by end of season i'll be ready to hit the shocker again

For those thinking of doing this mod...there are standard plugs out there that will get the job done. On the Rogue site, 2 plug types are listed--the NGKs that most people run, and Denso plugs. The Denso plugs have a removable terminal, whereas the NGKs do not. I did a search and couldn't find anything *negative* about the Denso plugs. Anybody know of anything? Both the Denso and NGK plugs are listed in the RC repair manual, so should be OK I suppose.
For me, not having to modify plugs at every plug change is a big plus. I'm giving the Denso's a try.

[pavementjunkie]

What is the Denso plugs part number your refering to? I'd be interested in running it also.

So if I understand correctly, this mod removes the coil packs from the sub frame(and wherever the other one is), the factory spark plug wires, etc?

Moving the entire assembly to the top of the Plug Boot that fits into the head, etc...

Curiosity asks, what about those of us who have the T1/Thorston box? Tolerences here?

Scott, if i just want everything but the plugs, for I too will be trying out the Denso's...$$$?

Nice work guys

[Redstar]

Jeff (Maverick) has a thorsten airbox mounted and he told me a while back that he installed the coil mod from Scott with no problem. Ask him.

[RVTMAVERICK]

Yep!... +1 with Massi,

Hey Ryan,

The SP2 "Front Coil" is mounted on the inside of the frame, left side, approx. same level as back of the front cylinder...
SP1.. I imagine it's in the same spot... ?

Rear Coil, you got it, sub frame.

Think about it, if you're get rid of the BIG OEM Coil and Thick spark plug wire,.. You'll Most certianly NOT have any problem with these new little things.. LOL

I like this mod. myself,
The ONLY down side is having to turn the spark plug tip(s)... but it's no big deal for me as I work in a machine shop.

Now it sounds like "RC51crazed" has a good IDEA\option in Denso spark plugs,... however that is something you'll just have to find out for yourselfs.. as I'll keep machining my NGKs.

I Hope this Helps,

Peace Jeff

[raceghost]

Maverick, and a BIG thumbs up my man. Sure does.

My shopping list is so horribly long...and dang, I have surpassed the value of my bike, stock...twice.... Oh well, it's all for science.


Oh Scooter....

[metalscorpio]

guys, stick around cuz i'm working on the next revolutionary idea for us to try.

Working with a designer right now in the idea and as soon as is finished and track tested i'll let you guys know

i'm sure you all will benefit from it just like the coils.

[thorsten]

Have read a couple of first and last replies.
Looks like it's all about an Idea og using Spark Coil Plugs for the RC .

Well, that is a difficult thing, as RC30, and RC51 are driven by real CDI's, no Transistor-Ignition, and CDI's do need Ign.-Coils with real low Ohms imedance, which ( as far as I know) no Transistor driven Spark Plug Coil has.

Thorsten, do you have a RC30 NLO CDI? i am needing some more RC30 goodies?

[dstewart]

Some one should test the max spark gap on both the OEM and CBR sticks. I had an adjustable spark gap tester, I may still have it somewhere. That would at least indicate if the CBR sticks are able to produce the same or similar voltage to the plug. Like this http://www.chain-auto-tools.com/electrical_auto_tools/AMB023L.htm There cheep, $10 to $15.

Hey Stewart,

FWIW,.. I've got one of those tools\testers but I never "CARED" to even test it because.. IF you check the Honda Service Manual(s) The "service limit numbers" fall within the Same EXACT Guide lines. For that matter, it IS the same as a 1993\94 CBR900RR as well and the numbers in My 1986 VF1000R Honda Service Manual>Yep, You guessed it= Exact same numbers!

I don't know why this is coming up again but what I CAN Tell You Guys is this.. My old RC51 is running like a friggin' BEAR!
She starts BETTER then Ever... ALL the Time... in other words Even when she's HOT.. She Still instantly fires up!.. Before doing this "Coil mod." when My RC51 was HOT.. it hardly wanted to turn over (Even bulking\kicking back to stop turning over and resetting my od!) never mind to Fire right up and I Know Alot of you know exactly what I am talking about.

Now when I started a thread about this mod., explanning that I was happy with it and the Thorsten big breather gasket,.. I was in contact with a member here who said His RC51 Fires up instantly all the time...? This to me seemed to the exception to the rule, as from everything I've read about you guys and your RC51s when they got HOT they didn't want to start for shit... So anyhow, there appears to be 1 guy with No Problem, I sure there are others...

I don't know what else to say\Tell you guys about this coil mod. other then it works exactly for what "I" wanted it to do.
When I did this mod., I was looking for it to aid the "Engine to Start Up" and to "Clean up the Engine compartment & sub-frame"! Anything else is just gravy
I wish I would have done a before and after dyno test BUT I know there'd be peps calling BS when it gained 5 to 10hp <jk>


I Hope this Helps,

Peace Jeff

[dstewart]

I am still curious as to the maximum spark gap between stock and with the stick coils. It would be a nice pice of mind to know the amplitude was approximately the same.
