    I thought you were selling bikes not collecting more?

    Did you find the extra cubes you were talking about?

    Hi Speedy
    Can you send us pics of the porting made on your cylinder.
    Here's the answer Paul ( nice guy) made to me when I asked about porting
    430 ae cylinder.
    Michel


    PORTING 430 AE CYLINDER BY PAUL ROONEY

    Hi Michel. Ok it is no good porting an auto for top end power as the auto
    only changes gear at maximum torque, & only revs out once in top gear. So it
    needs to be ported for more mid range power which is of more use.
    Exhaust from top standard = 40.mm, take it to 39.mm.
    Exhaust wide standard = 58.mm Take it to 64.mm. Keep the sides of the
    port as straight as possible.
    Square off the top of the inlet booster ports.
    Turn the cylinder upside down & drill 2 holes 1 each side of the inlet port.
    Drill from the transfers to the inlet & then grind out till you make them as
    large as possible & a nice shape. Do not worry if you cut into the cylinder
    stud holes as the head gasket will seal it.
    Once all this is done then take .25mm of the top of the cylinder.
    You will need to go leaner in the needle jet & up one size on the main to
    test.
    Have Fun Paul.

    My 82 420 is on Historic Plates,that wont work for you as its needs to be 30 years old.Plus there not to keen on major mods.Maybe look for a sympathetic blue slip bloke,good luck with that.

    G'day from Oz,
    Well Micheal I hadn't planned on pulling it apart to look at what Paul did but I'll think about it in the next week while I'm at work as I also have to work out how to make the rear engine mount 17mm to accommodate the 07 swing arm bolt. Im at work for 7 days & I'll try & get some pics when I get back.
    Cheers,
    Speedy

    Gday Michel,
    I finally got some pics of the ports for you.

    As you can see paul is pretty extensive with his porting, as to performance it now starts very easy & has a fat mid range which has made it really nice to ride.

    Here's a shot from the base of the cylinder.

    Just a quick update, the bike & I have had a love hate relationship (I loved riding it /It hated my lack of skill in setting it up right) with it seizing due to my lack of knowledge,(too lean/incorrect timing/incorrect plug & not re-torquing) but with perseverance, a brand new 38mm Mikuni with the correct jetting & great help from Paul Rooney, I've been out riding & we both had a blast. Now it only takes 2-3 kicks to start from cold & 1 when hot, I've also adapted an OR390 kickstart to get the frame/footpeg clearance I needed.
    I've also had the suspension done & gave it a new set of wheels with black rims which I reckon look ace.
    I've also just been given a helmet cam so I'll try & get some video on here soon.

    Hi Speedy
    Can you explain more what has been made exactly and with some dimensions ?
    The 2 inlet central holes seems to have been grown in the down.
    Can you send more pics, and from the inside of the cylinder ?
    Thanks
    Michel

    & this is the side of the bars that confuses most,

    & this is how it looks with the other motor, a 85 CR 500 6 speed.

    Note the taller cylinder.
    Now to go out & use them :banana:

    Well I went riding the other day & was having a blast until it stopped, at first I thought it had seized but found out later that a spring had broken & jammed & fractured the outer cover.
    So I've made a cover to hold a spring if it breaks & reduce the chance of damage.

    I've a question can the outer cover be welded?

    here's a few pics.....

    Don't know exactly if it is Magnesium or Aluminium, but a good welder can surely repair that.

    Thanks Wayne, the video image turned to crap when it was edited so I'm trying to find a better way to do it.
    Love the idea of a NOS cover but it aint in the budget at the moment as I've been out of work for too long so I'm going to a few welding mates to see what I'm able to do.
