Flat Track Adventure, Yamaha XS650 Special

Racing moto cross on KTMs, enduring enduros with state of the art KTMs, long distance adventures on big V twin KTMs...the list continues. Time for Jim to get a new bike...an 80's Yamaha!
Why the change?...Well perhaps Sideburn magazine and Dirt Quake 3 UK begin to have a bit of an influence.

Elbow to elbow, head forward and eyes locked on to the first bend and the starters flag, Jim is astride his latest acquisition, hastily prepared to make the first of many transformation steps from road cruiser to flat track fugitive set in a moment to become a battle hardened, dirt oval, sideways racer in DIRTQUAKE 2014!

 Now Jim's fledgling racer sits in my workshop for the second of many evolution phases.

Estimating perhaps an equivalent 1hp gain for every 10lbs in weight loss this XS is in for some weight reduction. Removal of the many unwanted road bike brackets and fixtures will start the process. Footrests will be reworked to save considerable weight and re positioned to tuck up out of the way.
Wheels will be changed to spoked items suitable  for the correct 19" Flat track tyres.
Handlebar controls and throttles are to be replaced and the quick removal of the front brakes will be facilitated.

New carburettors and Boyer ignition will provide an initial step up for the engine, closely followed by a bespoke exhaust system to exit to the right hand side.

The story will continue as we follow Jim's Yamaha transition from XS to classic Seventies dirt racer destined for Dirtquake 2015 and  DTRA 2015 (Sideways 60 mph and no front brakes)!
