    I had looked at those but they only do 35mm, a little spindly for my peace of mind.
    Jim Lomas though probably more famous for expansion chambers, another thing I have to think carefully about down the line.
    Lomas moved from the UK to Czechoslovakia so I'm not sure how they would fit up for a one off.

    I remember seeing an RD with hydroformed pipes years ago, they really have the anaconda that's swallowed a capybara look so I may well have a crack at that. The pipes will need to look slightly 'retro' though I think, we'll see, it's a way down the road yet.

    I always liked how the stock Banshee chambers looked, not the best for power.

    Stripped the cases with only one minor incident.
    I had to weld double nuts and put a load of heat in to get studs out, they all went with a loud crack in the end though.

    The rubber engine mounts caused me a moderate amount of grief. I tried a press and damaged the front mount on the case slightly, this stuff is soft as sh1t. Then I tried pulling on stud bar with heat and no luck. They actually seem ok but being 30 years old they can't be in great shape really.
    Finally I went round each one (of four) with a drill until I could get grips and pull the middles out.

    Then very carefully hacksawed the outer sleeves.

    And out. You can see the damage here on the front lug. I'll dress it out a bit better but still pissed off. Could have been worse, both cases now have all studs and bearings out ready for cleaning up and some port matching.

    Nicely done.

    I started on port matching today but my compressor just can't keep up even with the smaller 3mm. I roughed out with a 6mm but that just killed the compressor, I'll have to visit another workshop down the road, there's a few hours in this and the cylinder.

    I fitted the new dowels and dremmeled the ally gasket to match the transfer ports on the base of the cylinder.

    Then transferred the dowels and gasket to the case and marked up.

    Then I started but gave up due to lack of puff. I'll carry on tomorrow using a shop with proper compressed air not my under powered garage flavour.

    Goosebumps every time. I love Vale's expression when the pack flies by. He can't be an easy guy to impress.

    Finished the transfer ports today.

    IMG_2008.JPG


    And they match really nicely.


    IMG_1995.JPG


    I did some work on the inlet and transfer ports on the cylinders, not much but the photos don't look anything like as much work as I put in. I wouldn't even post the transfer ones as it looks like I did F all in an hour.
    All I've done is clean up any flashing from the casting and knife edge the ports where possible. I'm not touching the port timing as I don't want to change it and don't have the confidence to tackle it anyway.

    The good thing about stickers is that they can be peeled off...not just stuck on.

    I'm jealous, your dremel works. I came from a tool deprived childhood.

    Yes my Dremel works, it's in its case with its key. I was tool deprived from an early age (although I had my first torque wrench at 14...) but that's why now I try to keep things in order.
    Exhibit A. Every time I look at this I think...' You know what, you're nearly a grown up'
    I've nearly finished this can and the red tube is attached !!!!!!!!!!

    Useful tip of the day...... I once complained to WD-40 as I never got the last bit out ( and not been spraying upside down.) They informed me to look on the top edge where there is an arrow (triangle) pointing up, you need to align the nozzle to it! Been doing that and now get empty cans!
    And they kindly gave me a free can as well!:-)

    Great work as usual Wilde!
