I made a rough-up of the bracket. There's not a lot of room to play with, huh? Or am I missing something.







If I shorten those screws on the bottom of the guage I should have just enough room. I'll probably add a rubber gasket to the top and that'll raise it some. Let me know if I'm missing something though.

EDIT

On a re-read I see:

Think I'm going to figure out kinda a split-cup deal. A tall ring above the bracket to pull the gauge up, proud of the bracket. Then a shorter cup underneath for protection. Ah, I enjoy fiddling with things like this, I'll figure something out.

Got the LC-1 and G2 gauge wired-up and installed. The cup assembly I ended up with is a first draft. I'm going to re-build it and have the metal part powder coated, but here's what I have:





That's just black PVC pipe. Menards had some metal conduit that would have worked, but at $40 for a length of it I decided to go the cheap route.

I cut some ruber gaskets using hole saws from larger gaskets:




I used JB Weld to cap the bottom of the cup. An ugly job, one reason I'm going to take a second stab at it:

That actually looks really good. I hadn't considered leaving it raised, but it looks finished and clean. Nice job. Make sure to post some pics of it finished.

Resurected again !!

Hi all
There are quite a few threads on this so wasn't sure which one to pick. So its this one

Decided to go the AFR install route as fitted new exhaust and will be doing some other stuff later in the year.
Went with the Zeitronix Zt-3. Pays yer money take yer choice. There are a few to choose from, this was mine.



Hope to get it installed soon, however there are often unseen (but foreseeable ?) issues to overcome , not least where the bung is on the exhaust and room for the O2 sensor.




Comments and advice gratefully received.
Will update as I progress

Thumbs up First install

Hi all,

After a bit more searching I found the adaptor for the O2 sensor. It is an innovate 3835, as suggested in a post by Ventura I think.

I had to remove the exhaust to fit it as it is quite large. Installed with O2 fitted.

Now for the gauge. I took inspiration from you guys and made a plastic cup for it to sit in. I cut down the lid of a can of brake cleaner using the trusty dremelalike tool.
A/F Gauge install-img_20190217_154327.jpg

A quick tidy up with a file and attached together. A strip of insulation tape covers the join.

I cant decide where to fit it at the moment, however it fit nicely between the clocks and the fairing so held in place with double sided sticky tape. Not very secure as far as thieving bastards, but wont be leaving it unattended until a more secure fitting.

Forgot pics of the unit . Its under the seat. I will add that later.

So turned on ignition and the gauge ran through its start sequence

Started up and let engine get up to temp.

My idea was to use my helmet cam to record revs and readings. Good idea in theory, except I had forgotten about the LED flickering effect on recorded images. All I could see was odd numbers or parts of. Plan B time.
Getting a WOT reading will prove a bit tricky as I want to be looking at the road !! I did have a few quick glances at the gauge but couldnt see a stable reading with quick glances. The revs go into the red very quickly and so does my speed !!
Should I be going through the gears or just in top gear at low revs then WOT ?

More to follow.
Cheers
Jon

WOT ?

So I took a ride out yesterday to try some WOT ? readings.
I tried rolling on from about 40mph in top gear and then gave it "The Beans". Tried this a couple of times and have a reading of 11.5 -11.7 /1. Fairly rich then. I was a bit surprised as my butt dyno was going YEHAAAAA. Perhaps it needs recalibrating LOL. The missus offered to recalibrate with her boot . She's so helpful.
I was also a bit surprised as I had jetted with TTP long free flowing pipe kit. Perhaps the Arrows aren't free flowing enough maybe ?. I had previously been running Dunstall cans on the original downpipes.
I'm sure a quick call to @PieMan will give me an idea of which MJ's will get me in the ball park.

Cheers
Jon

Getting there

Hi all

Bought an air filter from TTP. Its a Uni filter that looks very much like a K&N. Not much difference in appearance, although the Uni looks better made.
Fitted it and went for a spin.
Have to say as far as I can tell there is no difference in performance. AFR stayed the same etc.
I then ordered 132 MJ from TTP and that has made a difference.
AFR at WOT is now around the 12.5 : 1.

So should I go for the 128 or 130 MJ ?

Cheers
Jon

BellaCorse has them: https://bellacorse.com/shop/keihin-cvk-main-jets/

These are real nice to have too: https://bellacorse.com/shop/cv-carbu...-thumb-screws/

I've bought the jets at the local Harley shop too. You need jets to a Keihin CVK 36 carb which HD used.

Hi Bonnie Black

Thanks for the response and the links.

I can get the jets easy enough as live in UK. I was wondering more what size to try, so will go for both and try them.

Those thumb screws are definitely the way to go. I changed mine awhile ago for some straight slotted ones. Much better than the D shape ones.

Thumbs up Getting There

Hi all,
I had an unexpected hold up. My reg/rec decided to cook itself and left me stranded. Fortunately a young lad in a car stopped to help me. Shame the 6 bikes that went by didn't stop. Anyway, managed to get home.
The stator was showing signs of over heating on one winding, so replaced that too.

Back to AFR.
Finally decided on 128 main jet at today 13.2 AFR. This was a bit surprising as I had jetted with TTP kit for my set up. This was a 138 MJ or 135 MJ with a 42 pilot.
Not sure what the actual size difference is, or what the numbers mean. Seems quite a large drop. Any ideas ?

As an aside, I was checking out TTP for some more tuning and it would seem they don't do the 790 cams.
Anyone got any to sell . How about some FCR's

Cheers
Jon
