Maybe it's because governments are threatening to go electric in 10 years? Making these illegal to use on the street...

It just means anything new made will have to be electric, not that anything existing is illegal to use

First chance at getting a few miles in on the RGV to start the break in.

Only rode about 15 miles, as I am not very trusting with going much further as of yet. No leaks and nothing fell off or came loose, bike shifted and stopped as I had hoped. The carbs will need some looking into, as the low end take off is poor.......along with the close ratio and my gearing choice (15-45) it is a real bitch to get rolling. Keeping the revs below 6000 is hard because that is just where this thing feels like taking off like a rocket.

Time to pull the tank and have a look see.....

 

Sorry the picture quality sucks...I need a new phone, but keep buying parts for my bikes instead.

I love those rgv’s like I love Lego, picking my nose, wearing my wellies on the wrong feet, putting a full pack of hubbabubba in my gob.....

.....I used to walk down to Padgetts at lunch time just to oogle at the rgv’s then onto Woolworths to oogle at the Lego....

I am done with two stroke projects for a while. I have a 86 GSXR1100 GU74, and my 78 GS1000 AMA style bike both in line next for the table.

So this long term RGV VJ22 has to go....Either in pieces complete as a project to someone, or just pieces. I have had it apart for 12 years now, and I know I will never get to it for myself....or to fix for anyone else.

A few more miles on the VJ21/SP. Trying to get the Lectron dialed in. Above 6000 the bike runs pretty clean and seriously hauls ass, but still weak below 6000. So I need to keep tweeking the needle some more I think.

Have not put much time into getting the carbs 100% dialed in. Too many other things getting in the way, as well as just being lazy.

I have over 250 miles on the bike so far, without the slightest issue of any kind besides carb tuning below 5000rpm. And in all reality, when I decided to first build the bike, my concerns for pulling away from a stop sign were zero. So the bike actually performs as initially intended. But as the direction of use has changed some, I am still hoping to find a way to get the bottom end better for intown riding as well as 130+ on the back roads. 4.1 needles in the carbs now have given me some help between 5000 and 6000, but at this point I am just wasting time till I get a few A/F readings.

I did get some use out of it this weekend though, and took it into town to a friends house for a cookout

Fork lowers I used a scotch brite type of pad on the bare aluminum to give it a factory brushed kind of look....Then I clear coated and baked them

Sorry a bit late to the party 

Clear coat as in sprayed on 2K ? Not clear powdercoat ?

Do you have any experience on how your finish will hold up ?

Not powder coat. Not sure how well it will hold up, but I have used the same process on several other rebuilds and have no issues yet. But I’m sure if it got scratched or hit by rocks it would come off.

 

I had originally built the RGV/SP to go to Bonneville salt flats, but after I finished it....it was to clean to trash with salt after all that time and work. But I am taking my Hayabusa to the slats flats (bucket list kind of thing)

so....still Suzuki

The A/F went from terrible to bad... So it was an improvement....but way too lean in the middle and could not change it without making it too rich at the top...I could make Good power up top, but I will melt it down while riding it anywhere below full throttle, after the dyno now. 

The Lectrons were a very expensive experiment to try and get a few extra HP.....and I failed. 

I am collecting parts to put the original 34 Mikuni's back on.....

Honestly I was surprised you went down the Lectron path, I've only ever seen them on drag bikes over the last 25 years... I would have looked at 36 or 38mm Keihin PWK Airstrikers, Mikuni TMXs or Tz250/RS250 carbs... 

I know of a few people who are great believers in the "Smart Carb", the next generation from the guy that designed Lectrons, but their promises are smell awfully snake oily to me...

Cleaned up a set of carbs I pulled from one of my boxes of spares. Look pretty good now, and have new gaskets/seals and jets to go in depending on what I decide to do to the airbox. I am giving up on the Lectrons for now

Also finally got my quickshifter switch, so I can now adapt parts from 4 bikes to get it to work with my Zeel ignition. Foot peg mount is VJ21 with the peg mount recut at 90 degrees. Footpeg is VJ22 so the shift lever can pivot from it. Shift lever is VJ23, that threads into a GSXR600 shift rod, that goes to the switch, that goes to a VJ22 lever....

All so simple...

28 degrees a few days ago

69 degrees today.....so....I got some bikes out to try and clear winter from my head.

The RSV4 not only cleared my head, it nearly melted my brain....

Also got the VJ21 SP project out with the new shifter and back to stock 34 Mikuni carbs and air box.

Shifter works beautifully. Feels just as good as my RSV4....very smooth, and exact. Very happy with the settings the Zeel has for it.

Carburetion....started off with all factory settings/Jets...and stock airbox. Bottom end feels much better than the Lectrons, and once it’s warmed up and the pipes are cleared out a bit, it pulls quite well.

Although, when I have throttle at 100% open, it seems to feel like I lose about 1/2 the power...7/8 throttle, and pulls strong to redline....same issue I had with the Lectrons. 

I reset the TPS, with the Zeel, for the 34’s....so....maybe a TPS issue...?

 

always something....

 

Pics are in reverse order...sorry
