 I'm sure this has been covered many times, I got a clutch spring from Randy great service. Changed the small clutch plate to the large one and removed the wire " what was that for " WOW can't believe the difference. locks right up and not that much of a work out, felt like a new bike again.
I'm no mechanic so if I could do it anyone can.

So much great info on here, thxs to everyone

Not quite, a new bike feel would have new clutch plates, one spring, a light lever and still have plenty of bite.

Sorry, couldn't resist!

As you may have guessed, I'm not a fan of this fix but as it is enshrined in FJ lore and cannot be challenged, I will likely be placed on a digital stake in the middle of the digital campfire and  burnt for saying so. That's what happens to heretics.

Many people on the forum have done this fix and it is very popular, even people WITHOUT slipping clutches are starting to do it.

Having said that, congrats on the doing the job yourself, it's very satisfying isn't it.

Now, go and ride it.

I don't find the pull at the lever hard at all, its little heaver and where the clutch was grabbing before the last inch and 1/2 its turned around and grabs the first inch as your letting out the clutch.
No slip at all even throwing a speed shift at 9 grand, its an easy fix and much cheaper, I guess I could of just used the new spring by itself but this worked out great.
Yes its always nice to be able to fix it yourself and save some bucks and I have been riding, its hard to get me off..lol

I also installed the uni pods a couple of weeks ago, didn't have to do anything to the carbs as in re-jetting, was running a tab rich before and now its perfect, nice brown tanning on the plugs and hell yes it goes faster..lol

I have done 70,000kms of recreational riding over 5 years and I still can't stay off mine. In fact it gets worse as I make the bike better.

You are sure to have a lot of good times on yours.

I found the same thing as Jim. Lever pull was not that much more than one spring, also this can be viewed as a preventive measure. If there was a spring that was about one and a half times the stock spring I think it would be perfect.

My clutch hasn't been slipping but the mod is on my "to do" list after the WCR. To late for me to tearing apart the bike.... I guess more of a pro active mod.

I am pretty slow alright :lol: I have to order the parts and my nature is while I have things are apart I usually inspect and investigate usually, leading to more parts :dash2:,
It's a problem I have......... :yahoo:

I just did the switch to larger friction plate. And Barnett coil spring pressure plate(going to use the used spring to double up in the 87) I didn't realize that the clutch was slipping, and was why it wouldn't do the power wheelies. I remember my first fj back in 86 doing . I put it down to the 60lbs I've gained since then.

Turns out it was the clutch not the extra weight!  Found the KOokaloo I remembered!!!

OK  I ordered the parts from Randy.....  :flag_of_truce:
The bike has 32K on her and I can see that putting a full size plate in the rear would be good and elimination of the little wire clip/spring up front would be less to go wrong in the future and the putting what I assume is an FJR 1300 clutch spring in her might be a good idea with 20 plus years and 32K on the original one. I don't know about stacking them, over 500 lbs of pressure seems like a lot. Guess I have a few days to think about that.  :pardon:  :lol:

George,

It is so easy to get to the clutch spring, and you don't even lose any oil, that you can just put the FJR spring in and see if its enough.  It was for my bike.
If it still slips, then open it back up and stack the 'old' FJ spring on top.

TNX Arnie. That's probably what I will do.

Mine is not slipping that I am aware of. My thought was to upgrade it a little to prevent a problem it the future. From reading it looks easy, cost is low, trading a narrow disk for a full disk can't hurt, getting that wire clip out of there is just one more thing I don't need in there to foul things up, the spring is probably not as strong as it could be after 32K, and last but not least I can inspect everything else in there.

Off topic but I sure like that F4i shock Arnie. Can't get over the improvement for 75 bucks and some time. TNX for your input.

George, you can fit and FJR spring, a second spring, hell, fit longer bolts and fit a third spring, but it ain't slippin' how will you know if it's enough?

If your clutch is NOT slipping why do anything?

All wet clutches will eventually slip. Unlike a dry clutch that slips when it wears down, wet clutch fibre plates become impregnated with impurities and oil additives and lose some friction qualities.

My recently discarded fibre plates for example were at the top end of the thickness range and the steels still had the machine marks at nearly 100.000k's.  I'm not hard on clutches.

When it starts to slip you can then decided whether you replace the parts that have become unserviceable or add another spring but if it's not slipping why worry.

Hi Noel !
            I see your point. I will probably only use one FJR spring. :good2: It was a used bike and I have never been in the clutch area to have a look see and inspect. I like to think the changes are minimal and in an effort to head off any near term problems. Very possably everything is good and with in spec as is. But "I" don't know until I look at it.

So while there it will replace 1 disk, a fresh spring, remove one wire/spring that can cause a problem and new gasket. When done I will know exactly what condition my clutches are in.  Not much different than if you pull the front forks apart you might as well do the bushings and upgraded seals....

I spent most of my working career around aircraft and we tried not to wait until a wing fell off (unlike Lockheed  :rofl:) before thinking about doing some inspections and modifications to head off a problem.  It's just my nature. I hate doing repairs on the road when I have a nice shop to work in and the time to inspect or modify.

Not to say that "stuff" doesn't happen, I just work the odds as best I can.
