Water is 25% more dense than oil. Even with the long columns I had to be careful not to blip the throttle too hard as it would turn into a water injection kit..... :-)

My 4-tube manometer just had all 4 tubes mounted to a single maifold and was mounted on a 4 or 5 foot plank of wood. I used 1/2 inch clear tubing so there was plenty of inertia and the common manifold meant that each reading was pulling against the other three.

Never thought about using oil. The water could be emptied after each use. Preety cheap unless you use Perrier......

Perrier? How about some red wine?.......
Never thought about making a manifold. I just wonder how sensitive that much water would be compared to a smaller amount of oil?

Been wanting to make a torque arm for the brakes, made this Saturday, mainly aesthetics, as it only weighs 1.8 oz less than stock; front will be less involved.. Made from some scrap 6061 alum on hand.

Well done, as usual. I don't know if you will be using a (relatively) stock centerstand, but if you are, make sure the tab that the return spring attaches to does not interfere with the brake torque arm. Regards, Chase

Thanks.
BTW, I read a post you responded to about a fellow you know who is reproducing stainless steel header pipes, I think in the UK - any insights on this?

Yes I found a nos center stand I am using - thanks for the caution.
BTW, where did you find the carb spacer vacuum fittings you will be using?

Guess I should have added the words "when retracted" at the end of the sentence. The clearance is certainly affected by what you use for an exhaust system aft of the header pipes. You may want to weld on some doublers (1/8" steel material, properly bent) to reinforce the bottom of the kickstand pads where they contact the ground. Lots longer life than provided by the stock material, and the additional height that's provided will help rear tire-to-ground clearance with whatever rear shock length and tire sizes you go with. I'll probably use the MotionPro 5mm vacuum fittings, just a tad larger tap diameter than your 10-32. Thanks, Chase
