Can I jack up the rear of my minibike and use the hydraulic disc brake to load the engine? If going to use a TC that shifts at 4000 RPM, I'll check at that RPM.

If I want to check 1/4 throttle A/F at ~4000 RPM, can I adjust the brake lever to give me 4000 engine RPM when the throttle is at 1/4 position? Put a new plug in, run a 15 second test, kill the engine, read the plug.

Then squeeze the brake lever harder so I need 1/2 throttle to reach 4000 RPM and repeat the test with another new plug?

I don't think I'd want to run 3/4 or WOT tests like this.

Any chance I'll be able to tune the clip position like this? Seems as though this would be more controlled than on the street. Think this would somewhat accurately simulate street conditions and at least give a baseline for a new engine, or new carb, ...? This is what they do when tuning on a dyno right? Only they read O2 sensors and torque measurements - and I'd be trying to look at the spark plug (which I have little experience doing).

Think this will boil whatever junk brake fluid that came shipped in this system from China?
Or does the TC belt just slip and burn up?
