Corn on the Cob or Crap in the Tank ?

The saga of awful fuel continues, the idiots on Wall Street and the other World Markets continue to play
and juggle the futures market on non existant fuel shortages while fuel companies, the dreaded green parties, and other gnomes keep adding dangerous chemicals to our ever worsening fuel quality.

No doubt the worst of these additives is the Ethanol mix which given time will eat and destroy all things
of a fiberglass, rubber or plastic compound. In terms of its dangerous capabilities the crap ate through
my BMW fuel line connectors spraying pressurized fuel all over my foot and could have easily gone the
other way over the engine with disasterous consequences.

From a trials rider’s perspective not only does our 2T mix go “off” with a marked loss of power but all
our after market pretty fuel tank units made of fiberglass all get eaten by this stuff with bubbles in the
paint and a soggy mess inside the tank gumming up everything from fuel cocks, carbs, reeds, pistons
and rings. All the known tank treatments from what I can see are only partially effective and eventually
break down themselves…… so surely there must be a better way ?

The number of TY Yams I see that used to sport the classic tank and seat unit have now been
converted back to bashed and unsavory looking old tanks and their $500 replacement units are sitting
in workshops decaying as more and more blisters appear.

What then is the answer ? Elementary my dear Watson, fabricate the style and shape the customer
wants and do it in ALLOY ! Now as Yamaha owners know the SM tank and seat unit was a pretty good
design for the TY250 but  perhaps the TY175 one was lacking as there wasn’t and still isn’t any rear mounting as the seat which is bolted on covers the forward mounting hole on the frame.  The only way
to attach at the rear is a couple of small holes and finish off with cable ties.

Latest TY250 unit, filler now on left and rear side panel removed? 

The new “Majesty” style ones made by Shedworks in Yorkshire DO fit the standard TY frame but again
they have a design flaw in so much that the tank portion goes back further than the mounting hole
meaning that yet again a rear mounting point has to be found.

This one is mine, the tank is still curving where it should bolt onto the

The following tanks are ONLY for Majesty frames and WILL NOT fit either standard TY 175 or TY 250
frames. They of course had the pleasing and distinctive “waisted” design that other Yamaha riders
craved but until Shedworks made one they were not available.

Majesty only tank in alloy at last !

So the thoughts are these, if interest is high enough to make it worthwhile WE, (well Ray actually)
could make a series of tanks giving several options. Firstly we could make tanks in the above alloy
Majesty style to fit both the standard TY175 and 250 frames. A rear section similar to that currently in
use would slip over the rear tank mounting bracket on both models or a total one piece unit could be
built, but here, other than looks, I can’t really see any benefit.

The tanks can be produced in polished alloy, or primed and etched ready for the customer to paint.
Finally a slightly cheaper option might be to produce a slightly smaller alloy tank whereby the current
bubbly blistered unit can have the underside cut out along the fiberglass side seams and slip over
the new tank acting as a shroud similar to the Honda designs on RTL’s and TLM’s.

If interest is high enough a prototype could be available at Turkey Rock (Jul 28/29) or Dolores for all
to see ……… however you need to GET IN TOUCH with me. ASAP

  1. An impressive share! I’ve just forwarded this onto a friend who was doing a little research on this. And he in fact ordered me breakfast simply because I discovered it for him… lol. So allow me to reword this…. Thanks for the meal!! But yeah, thanks for spending some time to talk about this issue here on your site.
