    Hallo.
    I have sportster 883 converted to 1220 (wiseco). With new pistons - I restored my 883 heads.
    After conversion my bike runs fine but on low RPM and when RPM lowers from high RPM - my back exhaust pipe is shooting with blue fire.
    Anybody knows - what is the reason of my problem?

    Leak at flange gasket, intake leak, carb TOO lean, pushrods not adjusted right. Start with a compression test on BOTH cylinders, check intake for leaks
