Same as the other post, for the injector!
If you are importing parts from Aus, why not go straight to Rajkot? I've found that I can place an order with Devprecision on a Sunday night, have it confirmed Monday morning, pay with Paypal - nicely protected - and the Fedex truck rolls down the drive, Friday lunchtime, prices are reasonable, compared to the uk, even taking postage into account.
I had a problem with an injector pump and after a bit of a moan on here, followed by me sending a link it was all sorted free of charge, no I don't have any other connections with the Sub Continent!!
When I built my 'bitza' I had terrible trouble with balancing, eventually I came to the conclusion that as it was a 3/1 bottom end, with the larger barrel and piston, the flywheels were weighted differently. I had an alloy 8/1 piston and rings sent out from Devprecision, it was a near perfect fit, and the engine is now as smooth as, at 650 rpm. Just a word to the wise for when you are putting the big pile of bits back together......
Cheers
