Yeah i guess it's still pretty close to the original Gardner/Doohan VFR
The fender in red is right and looks best, alternatively carbon fiber
Currently the bike is naked again and some ignition and wiring upgrades are being installed. But to quickly further on the previous issues with the says some new oem style mounts/stays were fitted.
After a few hours of going over the wiring diagram a Deutsch connector had been purchased and delivered to replace all the existing connectors/pigtails of the same wire counts. I have soldered the terminals on the connectors instead of crimping them as I have had issues with crimping in the past, here are some photos of the Deutsh connectors, they are totally weather proof and great connectors in my opinion from dealing with this so far.
250ft of M22759/16 Tefzel 16AWG Wire was purchased along with a decent pair of stripers and some heat shrink.
Its great to finally deal with this wire first hand, the insulation and the wire itself is tough as hell, without the stripers I would be in agony as I tried with some scissors for fun and it took forever. I am also really happy about the heat resistance of the wire as to get the best possible solder connection to the terminals I heated up the components very high and the insulation didnt seem to care in the slightest, all other wire I have done this with the plastic coating starts to get a droopy face.
Some NGK HT leads and caps along with some 3ohm dynatek coils where purchased and delivered.
Now I know what your thinking, "What the f**k is this!!!? Damus up to his old tricks again cutting corners!"
But honestly I used proper terminals and caps on my bike and honestly once I weather proof around the cable ties I can say with 100% certainty after rough testing this is a MUCH more rigid connection and when pulling on the leads hard the connection doesn't budge in the slightest which I cannot say for the caps/terminal connection on my bikes dynatek coils.
Also something else I can say that I am super excited about is
Yep its an ignitech, pre-installed with the RVF400 HRC mapping, the ignitech wont connect to the pc unless the tci is powered by the 12v battery but I will be connecting it up to get a shot of the mapping up soon.
More than anything it will be fun to A-B the original vs the hrc mapping with the extra 1k rpm redline thats for sure.
Once all this is finished it will be back to the body work again to quickly finish up the fairings/fitment etc. All the OKI decals and other stickers have arrived so should all happen pretty fast.
Small update fair bit has happened but still pilled in things to do etc etc.
So I pretty much just made up my own bs wiring diagram to go off because I wanted to remove some unnecessary stuff e.g. clutch switch safety, kill switch, all the stuff the Aus import bikes have bypassed like the headlight switch, indicator parkers etc.
This was the quick draw up but it didn't end up being exactly the same, I made some late game changes but I'll put it up anyway.
Pretty much ended up using all 250ft of wire, if you considering doing a full loom for one of these old Honder's your looking at a solid 300-350ft of wire for everything to be exactly the same including pigtails coming from the bike itself etc.
Here was some early in the making,
There was a funny song that helped me not go mentally insane while doing the job because it was actually a bigger task than I originally expected it to be, being that I wanted it to be "life time wiring" and look the goods and be perfect in every single way. Anyway the song was "The white wire connects to the... White wire. The white wire connects to the... White wire, the white wire connects to the white wire *repeat*". Multi-meter was abused on the regular.
Ended up using a motorcycle battery charger instead of a 12v batter to hook up the ignitech to the pc which worked out fine, although I was quickly just checking the installed map and disconnecting so it wasn't plugged in for long.
The stock VFR400 map looks like this:
This is the HRC map for the RVF400
Now not being confused by the red line shapes lets quickly assess the numbers,
both maps are the same from basically 10° from 0k-rpm all the way to 25° at 4k-rpm.
However from 4k-rpm to 6k-rpm the HRC map remains retarded at 25° whilst the stock map advances its way up to 30° from 4k-rpm to 6k-rpm.
About 6.5k-rpm is where the advancing ends on both maps with the HRC map remaining 4° more retarded than the stock map. This was interesting for me as it was probably a no brainer that honda would over advance the spark timing to ensure safety and reliability. I will probably purchase an ignitech for my mc22 as im pretty pleased with the product and I will probably adopt a similar concept when mapping the mc22.
The HRC maps redline is also a few k-rpm higher than the standard. I will note that even though the vfr and the rvf have the same engine the RVF has a longer valve intake/exhaust duration due to the cams which could be effecting the numbers between the two bikes but realistically the compression ratio or internal cylinder heat would be far from self igniting the mixture so my logic says that difference is irrelevant in terms of more performance orientated spark timing.
ANNNYWAY heres me and the loom ready to fit to the bike for further work
The loom has since been fitted to the bike and now I am just waiting on some sheath and she will be ready to test out soon.
I my self am really curious if I made any mistakes either with cross wiring or an over site with my circuit but I am pretty confident so I'll let you know how things progress.
In other news mc22 things will be happening in near future.
Well good job to get it finished, keep it coming.
The puritans go psycho about soldering terminals but as you said with the Tefzel wire it is moot. I will be food for worms long before my any soldered joints on my harness fail (when it is finished).
I do my looms on the bike and sheathe as I go, but hey, if it works
ps: You could add a standard RVF map, if it can store multiple maps, and then compare.
Yeah the rest of the loom work will be on the bike, still got to do connections on the bike side etc. I just used the old loom as a guide as to roughly where the components where meant to land etc. It all worked out cool, just gotta do some soldering on the bike end etc. Yeah the ignitech can store different maps, but switching between them on the fly would be impossible unless you where running 2 with a button to toggle between the 2 LOL wouldn't that be something.
The owner will be going for a dyno the second I get it back together so I guess I will know whats happening with my man card at that point. But at the end of the day its not my bike so I am not going to be battling for every quarter HP like I would my mc22, the RVF400 already has plenty of power if it was me I would be aiming all my focus on suspension on a 400.
