Running bike on a lift long-term
05/11/17 at 14:50:20

My first test run is going to be 3000 miles and I wanted to do this in a shop where it can be done in a day (please note that's an exaggeration). The issue of course is an air-cooled engine so I was wondering if I should look into some type of blower on the engine, or if it could just be run in open air for 3k miles?

I built a wind-tunnel years ago to test vibration on a 4-runner antennae and still have some high powered motors from that.

Kenny Yeah I know. The point is its a lot faster to run the miles in one spot and I don't have to find someone to go ride it.

A mighty Savage should be able to handle that!

I'm exaggerating, I mean its faster to run it at a shop than on roads and I don't need to find someone to go put the miles on. Just find someone that can add fuel and keep an eye on things.

Why?

You need a blower to simulate the speed at which you are running it.

At 70mph indicated, you will need to monitor the oil as well.
It's recommended to vary the speed during break in, so I think this would be a good idea as well.

I think I would tape the spokes to create fan blades so you'd have some load on it. Of course, this will create a side load that you need to brace for.

I would also monitor oil temp which can be done with an IR meter on the oil filter cover. And the head temp with the same meter. Otherwise there are bolt mounted temp gages that work well that you can attach to the sparkplug and the front oil pressure port.

How did we get from a whine in third gear to deciding whether to put 3000 miles on the bike on a stand vs. road? Please fill us in as to how you fixed the chirp. Inquiring minds want to know.

I haven't fixed the squealing front pulley, but the bikes in for a rebuild and Im having any parts related to it replaced.

So stage two will be seeing if I can get it to happen again and while I originally thought I'd put 7000 miles (the current odometer reading) it occurred to me that the rear tire probably only has 1000 miles at most.

Once I get the repairs/replacements done I have to put the miles on he new parts to see what happens.

I'm sure I have an IR sitting around, thanks for the advice there. I always forget about the oil.

Ive only got two, I already promised one to someone else. Would be cool though.

Those are not your goals. I'll cheer.

Maybe I am the weird one here - but I prefer to break in a rebuilt engine out on the road where the wind does the cooling, and I can vary the engine speed and applied loads to help ensure a proper seal on the piston rings, and enjoy the process. I can't understand what is to be gained by putting miles on a stationary motorcycle.
