305 Clutch Rebuild and History

[LOUD MOUSE]

Strange as it may seem I drink TOM MOORE whiskey.
Nothing at all to do with my last name being MOORE I just like the flavor.
I'll take your offer but you are required to bring it to TEXAS and we will enjoy it together.
Thanks for the offer but I help members where I can as I've learned the hard way at times and want to share what I know with others where a Thank You is plenty.
Now ya can ride!. ...........lm

I finally got all the parts: A Plate, two wire springs and five 020 aluminum core friction plates and got it back together.

I took the old dream out for a 20-mile test ride yesterday. I am getting a lot of clutch slip when I get into the torque curve, eg. going up hills or more than medium throttle in 2nd gear or above.

I am using Valvoline 4-stroke 10W40 motorcycle oil (it says meets JASO MA spec). Also, I put the clutch together dry. I read later that the fiction disks should be oiled prior to assembly?

Any thoughts or suggestions on a fix? Thanks in advance.

Ed: Just went for a ride. Nice crisp shifts, good pull from a full stop. I guess measuring the right thing makes all the difference. What kind of booze do you drink? I owe you. Many thanks!!!

Hi garncarz can I ask where you got your "wire springs" from, I am missing 2.

Call you local Honda (motorcycle) dealer and have them look up part number 22431-259-000 in their dealer parts locator. If available, they can give the the phone number of the dealer with stock.

Thanks I ordered them from David Silver last week, I was surprised to see he listed them now I understand why.

She started slipping again last week. So I changed the oil again (filthy after 50 miles, I guess its going to take a few flushes untill 50 years worth of sludge gets eradicated). This time I went to straight SAE30. Readjusted the clutch per our discussion. Good for 30 mile, now much less slip but still some on heavy accelleration. Maybe I should go to the white springs?

Anyone have the honda part number for the "white" springs?

This is a great thread but one thing that would help me is to understand what to aim for with a total stack width on the positioning of the outer most lip of the clutch pressure plate. With the mixture of 5 , 6 and even 4 disk clutch packs shown in various manuals it gets confusing.
I imagine if someone built up a 6 stack with 5 stacker discs the pressure of the springs would be lacking and it would slip?

I have looked through the manuals for a guide haven't found anything suitable. Given these bikes have been around along time and possibly been worked on by many the clutch variations of parts could be quite diverse.

I have bundles of pressure and clutch plates and some are obviously mismatched but would like to be able to construct something largely acceptable
