3xv: Project Phoenix

[Warwick]

If you are still using the -00 ignition for the time being it might be wise to connect up the TPS electics, strap it somewhere out of the way and wedge it in the full open position (just take the cover off and wedge something in to hold the arm in the full open position) as the TPS impacts the ignition curve (possibly powervalve operation too) as well as the VAJ. 

[Steveog]

I was planning to go to the Zeel with the pre-loaded curve, Warwick. I've had a look at the software and the TPS can be turned off. Believe you or Phil advised that. 

If I run into a shit-storm of confusion with the Zeel, the -00 ECU, TPS and VAJ/plugs would be easy to re-adapt. Thanks for the advice on the TPS. I would have never had know that.

I know my basic set-up pretty well. I'd probably go to #12.5 pilots, (adjust air screw and idle accordingly, #2 clip on the needle, and 260/190 mains if I went back to the stock ECU.

I'll keep the mains at 200/270 with the Zeel. The needle and pilot and pilot stock. 

Ran into a problem with the new temp gauge, but was able to get a new pattern sensor bolted up to the new rad, using the stock temp gauge.

Also, need to mod the mount for the RH coil, as the new Rad hoses now get in the way.

Lots to do, but feel good about the reasons for this work.

Have a good evening.

Steve.   

[Warwick]

Ah, OK. You should be all good in that case. I don't have any experience with the Zeel myself, but you should see a significant improvement in performance right off the bat with the programmed curve Id think as you will be getting rid of the current restricted ignition set-up.

Exciting times!   

[Steveog]

Yes, I'm jazzed getting to this point. HA. Guess it was Phil who advised on the Zeel.

Regardless, thanks for YOUR support throughout.

Let's see how happy I am with the 3xv and my work come Monday.

Grandson will be here Saturday. Trying to corrupt him with a little bike, but his mom has a major "Jones" against motorcycles. My son (who rode earlier in his life), wisely supports her, while knowing the day will come when Ben wants to "ride around the yard like grandpa."

Best to you.

LT50, gateway drug

[Steveog]

HA. Thanks Karl. Good suggestion.

I was planning on getting the grandson(s) on the 1986 RM80, but it now has no carb, not to mention a violent power band.

My Best.

[Steveog]

Its lunch break, here. Took the morning fabbing up a new RH coil mount, as the stock mount would have jammed the coil into the new rad hoses. Not good. That may have restricted the water flow (unlikely, as these a HD hoses, created a "wear point" and/or just looked like sloppy prep.

I modified the stock coil/faring mount, using 1/4" polycarbonate. Great stuff. It can be drilled, tapped, reduces vibration and never rusts or corrodes. Just need to get a ground back to the frame.

Need to check the faring clearance. That new radiator is bound to cause a problem.

Steve

Sorry about the typo on the picture.

[Steveog]

Got the faring fitted. The TZ Rad is much wider than the stock version. The faring is fiber-glass so pretty easy to trim, but it had internal air passages molded in that had to be cut back. No big loss, as I'm not running racing air boxes. It was like working on a full-scale plastic model. The pics were done right after I roughed in the faring for fitment. I sanded down all the ragged edges. It's tight, but it all fits. Thinking of adding some heat resistant, thin padding to the spots where the rad touches the fiber-glass.

I also mounted up the Zeel. As you can see from the pictures, it talks to my laptop. I turned off the TPS, Warwick.

All good today. I even got a letter from Scitsu saying they will fully replace their temp gauge and sensor. Its a long story, but working with people who make good on "your" problems are to be applauded.

Good Evening All. Its beer O'Clock.

Steve,

How are the airjets currently programmed in the zeel? You want to be careful with that! If one is programmed to open at high rpm that could kill your engine.

Take a screenshot of the zeel pages after pressing 'read'. We can advise from there.

I'm hoping that I can eventually teach the Zeel to control the VAJ's.

Steve,

Firstly; I'm glad you didn't have to look far to find an RM80 carb top.

On the topic of air jets; If you want to ditch air jets completely (i.e. both variable and fixed), you could convert the carbs to 1KT Formula 3 specification - you'd never have to deal with air jets again!

Regards,
James

[Steveog]

Thanks for looking out for me, boys.

Dan - Yes. I'll get a picture up within the the hour. I'm currently set-up to use only the fixed air jet in the VAJ. The VAJ blocks have been disconnected from the loom. I'm working under the proposition the simpler is better for now. I've read through Phil's "Zeel Set-up Stickie" many times and the idea of using the VAJ system for precision control of mid-throttle jetting is a long-term goal. I do appreciate your WARNING. The program was preloaded at the factory. I only turned off the TPS. Pics included. Obviously the bike was not running. At the moment, it has no carb. New pic coming soon.

James. Yes, I've considered eliminating the VAJ block altogether, but as I've explained above, there is an attraction to keeping the entire VAJ system. Maybe I'm wrong and that kind of programming is best left to guys like Phil. The nearest dyno I would trust with a 2T is about 3 hours away.

Can you explain the 1 KT Formula 3 mod?

Here"s what I found in the Zeel. I didn't see a VAJ control, but that's why I need your advice. Thanks.

Here's a couple of zeel settings I have used in the past. Have a compare to what you have. I think you can download the .zee files if you want to. These were on my RS so may not be spot on for your bike, but at least you have something to compare with

Hey Thanks, Phil. Very generous. You can read about my set-up. Do you believe the preloaded file that came from the factory is a safe start?

I'm 200/270 on the mains. TPS is loaded as "off", per your recommendation.

Very kind of you to share curves you obviously spent time building.

Steve

[Steveog]

As most of you know, when removing the TPS from the throttle system, extra slack is added to the cable at the point of mounting to the lower carb. The stock adjuster can't take up all the extra cable.

Here's a solution. You will need two stock TM28 carb adjusters and lock nuts, as well as a an extra heavy-duty shrink-wrap. The stuff I found also has "hot glue" on the inner surface. This junction is tight and solid. Believe the picture will explain how it all works. The open ends of each adjuster are just butted together. No drilling or re-tapping was needed. All parts can be used again.

The end result is very smooth and you can also retain the the TPS adjuster for future use or re-sale as a unit.

Now to get it all in sync with the rear carb.
