Stand failure has silver lining

I was tearing into my '12 looking to see if a faulty valve or lifter was causing my intermittent high speed stumbling. Took the car off. Removed the heads. Liquid tested the valves for leaks. None. Pulled the valves for inspection and lapping. Do the right head and put it on. Preliminary torque at 25 ft/lbs. Final to be 32.5 ft/lbs. Went back to the bench to get the left head. Heard a noise. Turned around and watched as the bike and stand did a slow right side fall. :shock: then :cry: then foul the air a good bit. Called the Mrs. for help and away we go.

Here's after the mess was cleaned up. Broken stand clamped to steel work bench then tied off to bench and mill base. Pulled the right head back off for reinspection. Seems fine. Preliminary damage report shows bent brake lever connector rod and bent valve cover stud. The front ground brace on the stand (removed in this photo) had tie down eyes that were held in with press nuts. The left one pulled out unnoticed and I suppose my working on the right head started her over.

THIS WILL NOT HAPPEN AGAIN!!!

A new stand was in order so here we go. I purchased a MaxxHaul model 70271 after one of my friends recommended it. Harbor Freight has something similar but after comparison this one was a bit better made. $69.00 at Amazon. Primed it in and set it up. Now how do I make it even more stable? The answer was to make the center of mass have to travel further (lean over more) to get to the tipping point. The easiest place to add a brace that didn't create a trip hazard was at the back of the stand but it has to be removable. Here's an early in-progress prototype. Te length of the brace tube is 26". It just peeks out from under the heads when the bike is mounted. Again, I didn't want to go much wider and create a trip hazard.

The leveling foot was converted to internal threads and a wing nut replaced the lock nut. I trimmed a threaded coupler and forced it inside the tube. Later a small 1/4" pipe spacer was inserted below the eye bolt head and the upper nut removed.

Here's the final look. The best way I found to use it was to mount and tie the bike in the MaxxHaul first then bolt the brace onto the frame and tie the bike to the brace. Lowering and locking the feet last gave the best result. Stable as all heck.

Can't use them both at once - or - I never figured out how.

I know someone who bolted an HF chock to a large 3'x3' square of doubled up 3/4" plywood.
Cut down a HF cargo strap to hold the wheel forward in the chock. That's it.
He uses it for maintenance and restorations on everything from 250cc classic Hondas to Harley baggers.
It lives in his motorcycle storage area taking up no extra space.
He just parks one of his bikes in it when not in use.

The MaxxHaul and Harbor Freight stands require you to push the bike forward into the stand, then at a certain point the rearward tire brace in the stand pivots up and 'locks' or 'wedges' the front tire against the stationary front brace - so it would then be challenging to roll the bike backward onto the centerstand without pulling the bike back out of the front wheel stand. Maybe there is a trick to do this that someone else can share.

WIth the bike secured in the front wheel stand, I suppose you could jack up the rear of the bike and then deploy the center stand.

Is this just a way to hold the bike up if you don't trust the center stand?

Yes 'tis. What I did was convert a truck bed/trailer stand to a floor stand that doesn't need to be bolted down. The bike is now safe, secure and can be left alone while I'm waiting for a new rocker arm assembly for the right head.

I was being sarcastic.
