    Done, the water cooled, twin powervalve cylinder.
    This one just gets a jacket welded around, it is just a one off after all.
    Cast along side some Subaru EA81 heads.

    Ok so how about an XL185?

    No, wait, I don't know what I was thinking.

    Back to plan A, rule change allows for water cooling now.
    So no need to hang on to the air cooled cylinder, the AG will benifit a lot from an upgrade to powervalve and water cooling. This cylinder Ive cast for the TF will fit straight on to the AG, exhausts and all. Time to make the change.

    The TF will now receive the new 54 x55 cylinder with proper cast in water galleries, a new crank required. I already own a 54mm single ring Aprilia piston. Still reed valve for the minute. Disc valve will have to wait.

    So my disc valve experience in tye dirt consists of a GP100 with skinny knobblies $40ea, but combined were well in excess of the bikes purchase price.

    Anyhoo, I did find that when going downhill on closed throttle, I wanted to blip over a small obstacle. Bwooar, clunk over it, bwaah(seconds too late).

    Reeds are good on dirtbike I concluded.

    Youve never ridden a proper disc valve engine, have you.
    Sliding gibb coupled with powervalve is a game changer.
    You should try it sometime.

    Cuppler things:

    1. Fletto has obviously written/writing the rules

    2. Where in the world can you still buy 2 stroke "chook chaser" bikes? Is Old Zealand still part of the world?

    Rotax256 in GP chassis seemed just fine as did a couple of KE buckets on longer tracks. (Shorter tracks were quite abrupt).
    Dirt is a different , but good to hear.

    Granted, a 1973 Kawasaki but, this is great fun on the dirt, even for the heavy pig that it is. No worries about what gear you are in just open the tap and point.

    Power band

    Got to say to say what impress's me the most about that 1973 Kawasaki is the wide power band 6000 to 9000. nice!
    Compare Pornography now to 50 years ago.
    Then extrapolate 50 years into the future.

    Rereading my post, the GP chassis mentioned was early 80s Ally short run 250GP chassis. . .not the GP100 I mentioned before. That would be just silly.

    No doubting a decent Rotary valve, but they, like piston porters have the potential to load up on closed throttle. More over an issue in the dirt on trail where long downhills are a thing. Reeds are so ideal for coping with this.
    You'd need some way of closing off the Inlet substantially to reduce this effect.
    Oh.
    Do you know how far you can practically close the gibberish timing? (Ha! Spellchecker error, but I'll leave it in for giggles).
