Here we go finally.

My parts area is almost set up. My 83-cr250 crankshaft is going out tomorrow to O'Connor racing to have the connecting rod kit I received from HVA to be pressed together. Getting the bug to get going.

Good luck with the build, don't forget to put up pictures so we can see the progress!

I know him, he is only about 10 miles away. Stop by if you do business in person as opposed to mail.

Me too.

better get a big bucket..

You don't share where's my popcorn? I like mine with butter, bacon makes everything better too.

everyone is waiting on pictures Bill ! PONY UP !!!

Bill great to see you start a project or two !! We like that !

Yes, leave the PC, go into the garage and
put the hands in grease !

My garage is still packed with used husky parts. Need to move them to make room for assembly. In the meantime I'm getting my shop work done on the engines. My cr250 crank is done with the new HVA connecting rod installed. Ken O'Connor Racing did the turn around time very quickly. Plus his videos on you tube are impressive with his quality workmanship. The cr500 crank, bottom end will go out next for a new HVA connecting rod and to be balanced. Everyone says the husky 500's have lots of vibrations. We will see if we can remove some of it by balancing the complete rotating assembly. Fine tune it.

Rebuilding the Husqvarnas one engine at a time, one bike at a time.

Not the O'Connor racing I know. Maybe these guys do not get involved with copywright of names. Strange the guy I know had some flyers listing crank work maybe 15 years ago.

Is balancing it or are you?

I'm not sure if I will balance it or not I need to make a fixture. I know how the static balance is done. Bill

how will it be balanced, only having one piston? are you going to balance the crank cheeks like a flywheel is or even a tire?

They static balance the complete rotating assembly. I seen them balance it without the flywheel and no primary gear which is strange to me. I would put the flywheel and primary gear on the crank too. Since the primary gear has no key a scribed line must be added for a accurate alignment.

The crank, plus the piston assembly and the flywheel / primary gear.

I asked Ken O'Connor if I could post some of his articles he gave me the ok.
