XS650: Right Hand Shift   Leave a comment

Somewhere in my shed I have a right hand shift conversion for an XS650. Came off a sidecross machine. Conversion done both to allow higher gearing (larger front sprocket) and prevent clogging around the front sprocket damaging the shift mechanism.

Also found stateside on flattrack machines. These are raced anticlockwise. Left foot, ironclad, generally run along the track. Left shifting prevents quick changing and is easily damaged when dropping the bike (unless you high side of course).

taking the curve

Relatively easy conversion. Separate the shift claw from the shaft. Turn the shaft around so the spline faces right. Reweld to the correct spacing. Add a boss with seal to the right hand case. Bolt in. Stateside Hoos Racing provides this service.

foot brake and gear shift-rhs … I’ve seen the ‘replica’ … a nice bike but NOT a replica, more a watered down image of what a street legal version could have looked like … nevertheless—


My old Triumphs and BSAs are all right hand shift too. As is my Ducati GT750. In truth I have no problem transferring between right and left shifting. Have more of a problem changing from Triumph to BSA. Triumph-1st is on the bottom. BSA-1st at the top.

XS650: XStraordinary   Leave a comment


What’s an Apache AH-64 worth? Around US$30 million – give or take a few thousand XS2-GS650/750s?

‘Falling Through’ on ‘Return to Target.’ Pretty dumb really. A helo fly-by at high altitude-in thin atmosphere. Was that a 1st Cav emblem I saw? There are old pilots and bold pilots but no old, bold pilots.

Officially no one was killed. However that bloke, at the end, running to the right, looks like he has other things on his mind than failed burger flippers. Maybe that bloke by the 44 gallon drum you see in the rh corner during the approach?

The pilot will probably get promoted sideways. To a desk. The cameraman? Will probably go to jail.

XS650: XS-Sport…Phil Little   2 comments

XS Storm … conceived as a quick makeover for late model 650 Specials

Phil Little. Racer turned Glasser. Omar’s Dirt Track Racing. Sold-on, 2008.

“ … street trackers were largely personal and scratch built projects up until 1988. Bill Birchenal mentioned that in addition to making dirt track tails for 650 Yamahas I should make full conversion kits … and it was the success of Omar’s Dirt Track Racing … around 1988 was the nexis for street tracker  popularity … at that point they were easier to build. The kit approach to street trackers includes Sportsters. Storz was the first to do this and I came along, a johnny-come-lately with my cheaper and easy-build SXR street tracker …” Phil Little

Yamaha 650 Street Tracker

This is the very bike that started the world wide street tracker trend. A complete ground-up makeover including stock engine rebuild. The engine is stock.

Norton Manx conversion … Yamaha 650

“I built this bike and developed a complete conversion kit (under Omar’s Dirt track racing name) to transform a Yamaha 650 into a Norton Manx look-alike. A simple conversion, completed without removing the engine from the frame or repainting the frame. Best using a standard model with wire wheels. 1974 to 1979”.         Omar’s DTR .

As Phil Little Racing he wants to market a ‘Sport’ kit. A la Craig Vetter and Tracy Nelson.

XS Storm .. Vetter, X75 Hurricane … Tracy Fiberglas Works

Neither street tracker nor café. “Sport Custom”- Craig Vetter, X75 Hurricane! Tracy Nelson, Fiberglas Works. 70s.

Relegated to Storm,  “conceived as a quick makeover for late model 650 Specials. Cast or wire wheel model. For an X75 replica, select a 650 Special with chrome trim. Black themed bikes suit later Heritages. I want a X75 replica, 19″ front, 18” rear wire wheels from a Standard on my show case bike. Of course means a swing arm and brake parts conversion.

  •   Body parts will be offered in coloured gelcoat – no painting.  Orange, Yellow or White (for repainting)

X650 Storm conversion kit for Yamaha 650 Twins.“Now the entire idea here is to offer you a cheap body kit that looks terrific and is easy to install. I think the kit will sell for under $900 but I can’t be sure yet. I know I will be able to make tanks for less than ever before because I have found a new anti-ethanol resin from a secret supplier (don’t ask, I won’t tell). This will eliminate the expensive interior tank coating process which I have done for the last seven years.

The tail design uses the stock rear fender and taillight. This saves too because I don’t have to include a taillight into the design or price. Another thing that will save you a ton of money is the fact that I will make the body parts in orange and yellow gelcoat. You won’t have to spend $400 bucks on a paint job. I will make the body parts in white for those of you who want to do a custom paint job. I will have a graphics kit which give a professional, finished look to your conversion.

You should be able to install the entire body on a Saturday. You pull off the stock tank, seat and sissy bar. You’ll be cutting off some seat rail tabs but the rear loop stays. Once you’ve sprayed your cuts in black you just slap the body on and hook up the fuel lines. I’ll supply the petcocks and gas cap. By Sunday you should be riding”.

no seat … no rear guard
