Morning Team, I have just machined a new batch of my Suzuki Katana ignition covers. These covers are thicker than standard, so stronger than originals. Cost is NZ$450 each plus postage. Message me if interested.

These are our latest offering. Engine ignition covers for the (80's) Suzuki Katana. I designed these and the talented patternmaker, Peter Van Rooyen from Auckland made the pattern for me. Have had a lot of interest so far. I will be very busy casting in the new year. :-)
UPDATE: Many queries on cost. At this stage they will cost approx NZ$400.00 per casting plus postage.

Have just made a couple of special brass Binks floatbowls for a Customer in Australia. I had to make the float level 6mm higher than usual to accommodate his carburetors. Customer is building an AJS V-twin racebike using 2 x early Bigport heads. I am really looking forward to watching his project getting built.

Here is of Dani Fink (The Blackburne Man) with his UT 1930 (Germany) with a 600 OHV Blackburne engine. He is planning to run his new Binks Mousetrap on this - and some of his other machines. Love the crash helmet Dani !!
