    Got back from the Dyno outside of Chicago late Wednesday night.
    The bike is still in one piece....makes more power than it did when I brought it...
    But runs like crap on the road now... Carbs or my intake to mount them I think are the real problem.

    Need to talk to Brooks at Lectron and see if my runs make any sense to him.
    A/F is all over the place and adjusting it for one only make it worse at some other point

    Going to dig out a clean set of original 34's and intakes, and get them ready if I get no positive answers from Lectron.
    Mount up the air solenoids back on to make use of the Zeel's option to dial in mid range.
    Late in the season now. I will probably pull my pipes again, and when doing so, pull my heads and get a better measurement on how much room if any, the powervalves have to close tighter....just for my own curiosity.

    Start the next season with a simpler combination where I can use an airbox, as well as time tested carb tuning parameters.



    Greed for speed, doesn't always guarantee you'll find it.....at least I tried.

    I've never used Lectrons myself, they always seem a bit too good to be true being so 'easy' to set up. That said, if you want to move them on maybe we could do a deal for use on my TZ? At least they would look pretty :D

    I am losing my faith in my tuning abilities....
    Issues with this VJ21 project, issues with the RS250 I have been working on, tried starting my own RS250 Cup bike and have a failing/wet cylinder...RZV has troubles again....
    Might be time to move on.....possibly put the original RZV front end and wheels back on and say good bye to it...

    I look at this bike everyday.... closest dealer to me that has one is 4 hours away...
    I feel a road trip is coming soon.... the KTM has only 3 payments left..?
    Doubt I will be concerned for a lack of HP, and should be satisfied with a bone stock bike for at least a year or two....

    I will let you know for sure. :beer
    Depends on what kind of feed back I get from Lectron. I know they do work on most everything they are put on, but I think the way they have to mount onto a RGV engine is where some of the issue is. Possibly why no one ever uses anything but the original 34 Mikuni's on a RGV.

    not for the rest of us.
    Would love to see you go to work on that little jewel.

    Sale pending.
    Going to a true two stroke lover, so it will finally be put back into use.

    Buyer wanted me to try and get the RGV together as much as possible to transport.
    Engine off the shelf and in the bike, along with all the other bits I could find and bolt on where they were meant to go...
    Amazing how fast a bike can be built when not OCD....
    Should be gone in about a week...
    ....just that much closer to a 217hp roller coaster ... :bow

    I spend too much time staring at the expansion chambers/pipes on two strokes. I could have worse habits I suppose.

    Wow, what a bike you are looking forward to. Some of the new machines are so dialed in from the factory, nothing needs done to them. (Well, maybe). Just don't loose sight or your 2-smokes. We enjoy you here so much. My RZ hates it when I bring home a new 4-stroker. More time for them, less time for it.

    They cut a little off the top, and it was a start towards a deal....but waiting til first of Dec to see if Aprilia allows more leeway in the price.
    When I bought my KTM the dealer cut about $4500 off the bike with various incentives and .9 percent interest.....I couldn't say no.
    They haven't done that with the RSV4 yet.
    I have the loan with great rate on my own.....but with snow here I'm not in that big of a hurry and can wait a little more.

    Cleaned up a set of carbs to eventually replace the Lectrons.

    Also finally got my quick shifter 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...:loco

    Quick shifter installed, and wired up.
    Need to get carbs swapped, and then find some warm weather and get back to a bit of testing, to see if bike runs better and if I can shift without a clutch.

    One wire from the Zeel and a ground I made for the other end of shifter switch.... pretty basic.... so I’m hoping it works as intended.

    Really clean installation, but is there any way to get the shift shaft lever and rod at a 90 degree angle to each other ?
    It'll have a better mechanical advantage and should be easier to shift.

    When up shifting through the gears, the lever ends straight up and down when engaging. Downshifting take a bit more shift lever movement, but downshifting is way easier for my non functioning ankle than up shift.
    The GSXR rod was as close as I could find to work with my ankle limitations.

    They will be coming off soon... then some road time to see if the 34 Mikunis work better...
    I think they will.
    I believe that 38mm might be just to big for a RGV on the street.



    I also got word from the guy in San Francisco that my bought my RGV..... is in pieces, and parts sent out for work to be done. He might have that bike done before I get my damn VJ21 SP done....:dhorse

    So it has a reverse shift pattern now ?
