    Hi Guys,
    this is a project I'm starting too early haha
    View attachment 6659 View attachment 6660 View attachment 6661
    Thought I would finally show my parts bike for those playing at home. Obviously I've pilfered afew thing :) it did come with the rest in a box and started and ran but the carbs were in dyer need of a clean and I have since used that set in my runner but this one might end up a street fighter yet :)

    I have acquired a terrible set of carbs from Tim today and my plan is to Frankenstein my 2 discarded sets of carbs into one good set.
    The 2 sets
    View attachment 7458 View attachment 7459
    Damage
    View attachment 7460
    Anyone have any ideas to get this out? I need this carb damn it!
    View attachment 7461
    These carbs were butchered, stripped pilot mixture screws WTH! and the main jetting was set left to right
    125,128,125,128 LOL how Tims bike even slightly ran with this is beyond me haha

    At this point in time I would like to say that I did not in any part do this to these carbs. Thank you your honour. Council you may complete your examination. Lol


    Also I'm saying go a track bike. Purely so we can finally test what yourself and kiffsta said about the kwaka being the faster bike.

    See how she goes on the road first mate, if it revs clean to 18000rpm and goes like a shower of **** you don't need new seals. If it bogs down then you might :) or tuning. I can help with both.

    Re the carb screw. Try an engineering supply shop for a 'left hand drill' about half the size of the screw. Carefully drill down the centre (with drill in reverse) and it should 'catch' and screw the brass bit out without damage to the carb.

    Easy outs and brass are not a good mix. Can you get the broken off bit out?

    Not easily I will have to get some other tools. It's on the too hard table for now, I'll come back to it.

    Ok with it being stuck best way is to edm (electric discharge machining) while as a fitter if a tap snapped in a job this was best way to remove without damage
