I need some help. - Motorcycle-Journal Forums

My friend and I are about to tear into his '90 CBR 600 to change the fork seals. We can't find a good area to support the front end of the bike. Does anyone have any experience with the '87-'90 CBR 600? Here are some pictures.

This appears to be the only sufficient support for the moto.

The underside of the bike is all exhaust manifold.

Can anyone help?

Not sure if this is of much help, but viper94bite has a '91 CBR600F2. I believe 87gsxrnut has experience on older Hondas too. Shoot them a PM.

Thanks.

Tie (anchor in some method) the rear of the bike down, and use the center point of the manifold (where it is the thickest) to jack from. Use a 2 x 4 between the jack and the manifold if you want (you can cut a semi-circle groove into the 2 x 4 to make ot fit more snug against the mainifold. Otherwise, you can use two jacks, one on each side of the motor. Or, you can get front and rear stands and have no worries.

I do not recommend jack stands working on motorcycles. I have had them fail (retract) due to the weird angles sometimes they are used at.

Thanks for the tip.

This does not put too much strain on the manifold? That was our main concern, and also why we didn't lift the bike tonight (the jack stands did not provide sufficient support on the right side of the bike).

What about straps to ceiling beams to lift the front end?

D_Klein · 05-02-2006, 12:14 PM

That seems to be the best (and most cost-efficient) solution, but the ceiling in the garage is drywall. I wouldn't have a problem punching through it if the house weren't a rental.

I wonder if some of those threaded hooks would work, installed into one of the beams.

Do you have access to an automotive engine hoist (cherry picker)? Not sure if it will work, but if a friend/neighbor/nearby relative has one, it may be worth a try.
