Yes, you're right of course. A good belt with the Karcher and a scrubbing brush would do the job nicely and the ground would dry out again by the next weekend so this Sunday afternoon I'll do that. I'll put a tarp under the car as well to keep the run-off running off. Oh, for a two post hoist!
OK, now it's time to discuss your tank. How big is the tank itself? How long is it, how wide is it at its widest point and how far along is that point?
If it's so small that it has to be backwards for you to fit in it I'd say it might not matter much aerodynamically (don't quote me) but if it is going to be a motorcycle streamliner you might find it wants to swap ends at speed when the aerodynamic pressure exceeds the traction, particularly if you suddenly got some high speed wheelspin on a soft patch. Plus you'd never hear the end of it from most observers! If you decided to build a lakester with it instead you would get a lot of bulky componentry out of the tank space and have much more resistance to spinning out. And as I once suggested to Dr Goggles, if you put full wheel covers on it you could run as a streamliner too. Any favourites in the engine choice yet?
And just for the Queenslanders, Hare & Forbes at Coopers Plains is having a sale now until Saturday. No, they aren't paying me for this.
