    very cool,

    bummer about the power valves bro, didn't ya set em up when u put it back together? and do the servo check by earthing that spare wire (its how it gets done on the RS anyway)

    at least the valves were stuck open and not closed I guess? or you'd prob make no power hehe..

    whos wee NSR? i like them, cool shape - almost bought one over the Aprilia RS, but was more expensive and older.

    can get a sweet 300cc kit for those NSRs too

    I think i had them set up right but the servo stopped working, not sure why yet. Could be a loose connection, servo's fucked, sapc's fucked, will look into it this week.

    Anyone have a 22D30 sapc spare? i could defiantly feel the 22D70 i have start killing the power after 11k rpm.

    Or does anyone have the contact detail of a Englishman whose name i think was Paul. I was talking to him yesterday and he said he had 2 spare but i forgot to get his contacts, he was the owner of that #97 RGV in the 8th pic.

    The NSR is my mate Joe's bike, i will tell him about the 300cc kit; hes thinking of turning that bike into a racer.

    There's not much to go wrong with the servo - 1 power wire (that the SAPC contros) and it's earth, then 3 wires for the PVPS (position signal), 5v, earth and signal, all which go back to the SAPC. Those are easy to identify on the wiring diagram, and should be easy to continuity test back to the SAPC. I have a spare 22D30, I've only tested it on a bike but never run with it, $150 if you want it (same as I paid a few years ago).

    If you power up the 2 wire plug briefly it'll try and rotate the motor; only briefly, you're the feedback loop (instead of the SAPC). If you measure the PVPS, it should be a changing resistance across 5v and signal, as you rotate the pulley by hand.

    If the grey wire works correctly, then the wiring is presumably fine.

    The bike was good except for one thing; the power valves werent working, just meant i was down in power under 7k rpm.

    More to the point is what the fuck are you doing letting the revs drop under 7k on a race track???...what are you waiting for? Fasteddie to finish his RS???!!! Slap that clutch lever like it's going out of fashion and stop fucking about.


    By the way congrats on the build and excellent thread.

    Sure, also consider buying a Zeeltronic box instead (it comes with all the maps for all the useful SAPCs preloaded).

    Don't get it done here, get it done by Sean. He does exchange. He is cheaper iirc. He knows about bridge relieving. He'll make sure it's sized to the replacement pistons.

    Bascially, he knows his shit, and gives a crap about a good job. Even if it cost more than local, imho that is worth paying more for.

    nickasil, and its fucking expensive. potentially cheaper to get second hand parts than to recoat.
    are the cylinders removable? just resleeve instead?

    They don't have a sleeve. Nickasil (not convinced of spelling) is a coating of the aluminium to stop it distorting and melting at higher temperatures.

    Sleeving has been done, but it's not ideal as it doesn't cool right or some such similar issue.

    About $500 per cylinder and way better than sleeving, unless you're a total muppet you should only have to have it done once

    http://www.nzcylinders.com/ are the only place in the country that do it and are good to deal with

    Thanks guys, a guy I was talking to on sat had 5 pairs that needed replating, I didn't envy him.
    I had thought the zeeltronic boxes required a dyno tune, good that it doesnt

    Screw $500. http://www.thetuningworks.co.uk/asse...nditioning.pdf

    Sleeving it will fuck it.

    Second hand shit is just that.

    The Zeel box would of course benefit from tuning on a dyno, but you can have the same curves as any SAPC to start with.
