I did the tracker some years ago. It came from a Transatlantic speedway challenge series in which Brits rode modified Bonnevilles and American's used Shell-framed Yamaha XS750s (bored out). The bike was acquired by Bob Berry, Editor of Classic & Motorcycle Mechanics magazine from the original promoter of the series. He claimed that this bike was ridden by Kenny Roberts but I think that it was probably Dave Aldana's.

All I got was the frame engine and wheel hubs. The bike was done as a series for the magazine in the late 90s. Photos are pretty much all 35mm slides so I'll try and sort something out for you.

Got the gaskets and am now back in UK - thanks.

You get incredibly wet and covered in sand but if you do it on the back lawn it just becomes part of the soil.

Interesting!
Do you just replace the pressure washer gun with the blast gun?

Yep - you get a replacement lance with a Y piece at the end. You dunk the plastic tube in a bucket of dry sand and the jet of water draws in the sand. You can buy expensive stuff but block paving sand will do as long as it's dry.

See http://www.pressure-washer-parts.com/k_620_parts.asp#

and KAR-22020 at the bottom of the page.

Thanks, G-Man,
I guess this method cuts down the possibility of silicosis also!
Do you happen to have any pics of parts cleaned by this method handy?

Only example I have to hand - the engine had spent quite a while outdoors.

I can vouch for the effectiveness of G's suggestion, Brew; I once had a Karcher pressure washer that came with the grit-blasting kit of which G speaks. It had a bucket of black grit with it and left my 15-year-old brick wall looking like new! Pretty messy, but what a result. Grit would be a tad aggressive on alloy, but dry building sand should be ideal. Test it out on an old casing, or similar, first.

Wear oilskins, wellies & goggles -- or a full wetsuit!
