Hi Jimbo
I have a the TM34's on my build, purchased as conversion kit specific to the XS650 from Mikunioz here in Australia, getting close to first start up. Keen to hear how you go with yours, fitting the throttle cables has proven to be a challenge due to the dual taps being so close, I think I have it sorted,
I bought a pair of filters from Ramair in the UK, they have a good range and good prices, these fit well between carb and bat box, I had to mod the side covers a bit, I'm not keen on the pod type filters.
