Getting more out of a 80LF

[motoXman]

Can someone give me advise on my secondary? I took mine apart because the wear pads for the ramp were melted and the secondary wasn't running true. When I unbolted the helix from the 3 hole cover the spring was in position 3 and it seemed to be preloaded almost a quarter turn. I reinstalled the new part (same OEM number) reassembled and now when it back shifts my motor looses a lot of rpm and power on the top end. What could I have done wrong? I tried position 2 and it mad no difference. It seems to me what is happening is that my spring tension isnt enough and the ratio becomes too tall too early on the backshift, where Im not sure is if i preloaded the spring correctly, or if the new pads just made that much difference. Any help greatly appreciated!

It sounds like you wound it wrong.

[motoXman]

What is the correct way to preload it? The book is vague, it just says to turn it past the proper ramp by one and lock it down. It doesn't even say which way to turn it.

[harleysportster]

Rotate the cam clockwise.

Thx harleysporster, after reading that again I think may have wound it past an extra ramp. The clutch is hard to work on when on the jack shaft. It would be nice if the clutch would fit on after assembly. I have the spring in position 1 now but I think I will have to put it back in either 2 or 3. Going out for a rip shortly to see how it performs

The clutch should go on after assembly.
I've always worked on them on the bench and put them on after they are together

You need to hold the clutch open or hold the cam in when trying to slide it onto the shaft to fit past the pan. Took me a while before I figured that out.

Thx again folks. It still isn't working I've tried this 4 times now. I have the spring in hole 2, limit spacer is in, helix turned clockwise to the ramp, posts are seated and its just lousy. All I did was replace the part with the plastic slides. This machine performed like a top until I did this. When I first get on the pipe it revs 8000rpm and pulls hard. When it tries to back shift it's delayed and when it does back shift it drops my rpm to 6000 and its a dog! I do not understand what is going wrong. I have taken it all apart, double checked everything and reassembled 4 times now. According to the book my symptom is that my spring is wound too tight causing a too high of a ratio and drops rpm. I have tried 1-4 on e adjustments and there is no change whatsoever. The only thing I can try is to not wind the helix to the next ramp, but if I do this the secondary barely snaps back so I'm sure I have it right. What else can I do? Maybe I should just put all the warn out setup back in because it rocked that way! HELP thx!! I've ruined my good running machine and the snow is coming down as we speak!

The secondary spring controls how fast the clutches shift back into a lower gear. If the secondary snaps back as you say it should be assembeled correctly. Since it doesn't- go back to the primary clutch and make sure the weights, rollers, and movable face move freely and are not worn. It may be that the primary is sticking not allowing the secondary to back shift like it should

[motoXman]

Primary looks ok without taking it off and apart. This sled ripped until I touched the secondary. I believe the secondary is assembled correctly so something else could be going on, but as a coincidence happened exactly timed with me tinkering around with that clutch. Just my luck.

Just to add to my post, I tested the clutches on the stand. Both primary and secondary open fully without hesitation so this issue is under load. Being the fact I changed my gear ratio it should have NO ISSUE pulling the top end. Any ideas?

[Matt]

How about the arrows mentioned in the tech manual, do they line up?

[harleysportster]

I have read that if you change the gearing as you did, you should install the secondary spring in the # 1 hole.

Funny thing is this Trailfire clutch has arrows but not the liquifire one. Wierd. Is there anyone out there that does LF clutching? I'd like to have mine done, or replaced by someone that knows what to do. If the clutches work then I guess next is to do the motor... Maybe it's just plain power loss

[motoXman]

I haven't tried the 1st position yet, I will try and let you know harleysporster thx

[motoXman]

Still a no go here. Any other ideas? I'm thinking my problem may be beyond my clutching now. Not sure where to look next
