I am trying to replace the fork seals in my 1987 Kawasaki ZX750F. They are leaking bad! I have the forks off as the manual describes, but it says that the fork tube should work out of the bottom of the fork after I took the allen bolt out of the bottom. It appears that the seal itself is the only thing holding them together. What is the best way to get them apart so I can change the seals? I do not want to put too much pressure on anything for fear of causing damage. Thanks!

Make sure you have removed the retaining clips from the top of the fork seals. You didn't mention you had done this. Try clamping the tube in a vise. You can use some blocks of wood to protect the metal. A good place to clamp the forks is where the brake caliper bolts are tapped. This way you won't leave any serious marks on the lower leg. Give the tube a good stiff pull up and the seal should pop out.

I own a 1986 Honda Shadow 500 and was wondering if it has a pressure relief valve or something on the oil pump housing. It is leaking oil from a perfectly round hole on bottom of shaft connecting it to block!

You've got a leak. Get yourself a repair manual and follow the repair procedure for replacing the seal. I suggest you check the oil level in the motor and the drive shaft unit before driving it any further. If you absolutely need to drive the cycle be sure to closely monitor and maintain sufficient oil levels until you can permanently solve the problem.

I have a 1982 CSR1000 Kawasaki, when I got it the owner said that as soon as you turned the ignition on it blew the main fuse. Now it turns on with no problem but it acts like the starter button doesn't work, but I metered the starter button and it's operating fine. Before I start tearing it apart, is there any known parts (starter, wiring, etc.) known to have any problems in this area on this bike. Thanks

You'll need to test your starter, and the starter solenoid. If you need additional help with this I suggest you purchase a service manual that will detail the process.

I have a 90' Suzuki 750 gsxr. when I started it this spring it wouldn't run without the choke on so I pulled the carbs off and cleaned them. me being me, I didn't take the jets out, I just sprayed them with gum out. I put the carbs back on, started the bike and was surprised to discover that the bike would not idle down (though it did run with out the choke) I turned the idle down (all the way) it made no difference. also when I cracked the throttle it would rev down very slowly
and would backfire (occasionally) through the muffler. also-the oddest thing- the 2 outside cylinders got very hot, while the 2 inside ones remain just get hot. as far as I can tell there is no mixture screw on the carbs. there is a pilot screw (I don't know what that does though). so-
I pulled the carbs back off, went completely through them (cleaning) including adjusting the butterflies so they close all the way when not open. I put them back on to reveal the same outcome. the only conclusion I can come to is that there is an air leak on the intake boot (manifold.) what do you think could be to blame?

I know you don't want to hear this but I think your carbs may still have some foreign matter clogged up in them. I suggest you either take them to a shop that can fully disassemble and clean or buy a book to tell you how to do it and then properly adjust the carbs for your bike.
