The Bill Simpson Racing/Wes Cooley GS Thou goes into the crate bound for South Africa next week but I managed to get a few shots of the new titanium exhaust before she heads for warmer places —
The blueing on the headers happened on the dyno when setting up the carbs to suit the new smaller bore exhaust.
These are the bigger bore headers fitted previously —

Quite a difference —
The eight valve 1098cc motor was kicking out 108bhp at the top end when fitted with the stainless steel big bore pipes but that was reduced to 106bhp once the smaller bore set was fitted. The benefit with the titanium setup is a reduction in weight and a virtually flat torque output giving 77ft.lbs all the way from 4500rpm to a conservative 8500 which should work well with the old five speed gearbox.
Granted she’s a diesel – but a real nice diesel from a shop that knows their race craft.
These are TZ350 swingarms custom made in-house —
The big Susie has lots of clever touches —

Excuse me while I call my bank manager – he might just lend me the necessary spondulas to fund my own Wes Cooley Special 🙂
