Here's a link discussing the SH775 Polaris RR: Shindengen SH775 Regulator. Read the first post.

I would recommend changing to a series RR to accommodate the change. There are several out there, one for a Polaris ATV/snowmobile that is a series RR but the older non-MOSFET technology that may be easy to fit. This would reduce the issue of how much power gets shunted to ground.

Was going to use a series RR before the stator went for a trip south. Changed to the external alternator mod. Have LEDs now, but using an automotive alternator is different than the 3 part alternator system that uses a stator. Know of one 1200 that has the SH847 series installed. Know this...

I'll dive in here. There are two types of RRs, shunt and series. The OEM RR is a shunt style, "shunts" excess power to ground. A series RR starts/stops current flow. Both types of RRs have a reference voltage of approximately 14.2 VDC. This is the electrical system voltage that an RR tries...

It's getting very interesting. Doing some short road trials at this point. Want to determine where the engine MAP starts to be a non-supporter. The CFI system uses SD and Alpha-N fuelling profiles. There are four 16X16 fuelling maps, two for SD and two for Alpha-N. Alpha-N is used in the...

Had another road test today with new plugs, the ones I took out yesterday were quite black. As with initial tuning, the VE table is the key. This is the VE tables from today. The VEA table is an analysis of today's road test, the ECU VE table is what I have been tuning to. Very neat what can...

have started a new thread about road trials at: 1985 GL1200 Limited ECU Replacement/Upgrade - Part 3 - Road Trials

New thread needed. The Part 2 thread is at: 1985 GL1200 Limited ECU Replacement/Upgrade - Part 2 Mentioned this in the last thread: "Good news and a milestone. Went for a 7-8 Km ride today. No sync losses, but the O2 sensor is indicating a rich mixture. Had it up to about 80 KPH. The engine...

Good news and a milestone. Went for a 7-8 Km ride today. No sync losses, but the O2 sensor is indicating a rich mixture. Had it up to about 80 KPH. The engine operating temp went to exactly where I thought it would. Four bars on the temp dash temp gauge when on the road. Noticed the rear brake...

Not really patience, but definitely not letting go. Road trials will be starting soon. Have the tablet platform installed and trialed: Tablet Install.JPG (77.37 KiB) Viewed 1 time New tablet battery on order, used tablet to be expected. Have a car charger coming as well. Think the battery...

Thanks for the "(y)". Staring the final document regarding this project, lessons learned. The key issue with this project was not being as patient at the start as I should have been. Thought it would be simple and pushed ahead at the "high port". Not a good idea. Slow and steady wins this race.

Had some time today to make some progress. Front brakes have been serviced, front wheel turns freely. Will still need a good maintenance period before the summer. Good news, bike is out of the garage: GW out of garage .JPG (77.52 KiB) Not viewed yet Will have to wait until after Boxing Day to...

Thought I’d do an update before the New year. Lots has been happening. Have the bike ready for road trials, but have to do some maintenance on the front brakes, seem to be dragging – next week before end year. Want to do a trip around the block before the New Year. Have had to do some mods to...

Thanks for the likes. Still a novice with this new ECU, the EFI world and the physical change. This is like going back to college/university after a prolonged period for the course "1985 Honda ECU Replacement"; however, the different classes that you must take at the same time to get to the...

Short update. I mentioned that the mig/stick/lift tig welder came in. Great for the small projects I have. Bit rusty but welds are getting better. Grind the welds flat and paint black, can hardly notice. Bought an auto darkening helmet as well. New tech is great. Have all the small brackets...

Have a short update. Have the COP units fitted, not an easy task with the limited space available. The wiring is just about done, mostly routing and securing. Very busy wiring where the OEM RR was located. Changed where the fuel pressure regulator gets its vacuum from. Had a separate...

Not very good myself. This is a picture of the bracket material I'm doing first mig welding on, not a lot to it. Going to do a bit more practicing to get a better product:

The welder came in as did the new helmet. It's been a long time since I did any welding. Decided the mig option would work for the small welding projects I have. Tested on a pice of angle metal I have, and didn't do too bad, but there is lots of room to work with. Did some mig welding this...

Welder came in yesterday. Nice little 120 VDC unit. Does MMA (stick)/lift Tig/Mig. Not commercial quality but good for DIY garage use. This YouTube video is interesting: This is the unit: Now to look at auto darkening helmets. Have a cheap $15.00 one, but my eyes are worth more than...

Bear on a bike comes to mind!o_O
