Not a good comparison, but I had shorty's on my old YZF1000 trackbike - only got to really experiment with them a few times at the local roadcourse, but I felt that they did help me keep good grip on the bike in the turns - had more confidence with throwing the bike in deep, maintaining throttle control, and maneuvering myself around inside of the bike with the extra grip - but for drag/street use, they're probably more of an acquired taste.......would assume in a drag application that you'd lose clutch feel with a shorty. Have been considering ASV shorty's for my 14, but unsure about streetability with long rides and hand fatigue - at least with the clutch hand, brake hand would definitely be a plus as I only 2-finger it anyway.
I'd almost go for these myself, but alas.......I'm addicted to quality more than saving money.......still a good find Rook!
Seems like decent bang for the buck

Speaking of that clutch sensitivity, I don't know that two finger clutching is something street riders would do a lot because we would squeeze our other two fingers under the lever. I guess some develop a partial clutch modulating technique to maintain traction under hard decel but I have only done this a few times on the street. That would be an absolute all out high speed technique or maybe a slippery road precaution. I'm sure a standard length clutch lever is perfectly adequate and probably even preferable for most riders.

No, I brake 2-fingered not clutch......but I have tried it and smashed my fingers a bit -- I keep my brake lever adjusted out so I can get full pull without hittin' the grip or my fingers

OK, I'm resurrecting this thread with an update on the ASV clutch lever issue I had (and I think others did, too). The clutch seemed to be preloaded too much, so when you whip the gas open too fast, the clutch would just spin up. When I put the OEM lever back on, it was fine.
I spoke with ASV and the head of tech support said that some early levers (that would be probably anything ordered last year) had that issue. The replaceable barrel in the lever has a blind hole in it that the plunger seats into. That blind hole needs to be deeper. He did NOT say by how much. But he is sending me a new barrel (free) with the deeper hole.
I can measure the difference if others want to drill out their existing ones.
I hope this helps someone out.

I wouldn't drill them out, I'd ask for a new pair like you did.

I would expect returns or replacements on ASV or Pazzo but these Chinese levers? Forget it. If they do not work, they go in the trash and I'm out $41.
Got the levers last Friday. Delivered on time. They look nice. Only complaint I have is that the blue of the grips doesn't match the blue of the levers. The busa.org boys are all over these. Only complaint I heard was that a chrome pair would not fit into the notch they pivot in. Turns out the problem was that the chrome was too thick. Had to be milled down by hand and then they were fine. How about that? $41 levers that obviously have a good heavy layer of chrome on them. Cheap and high quality. I'm impressed. One of the org guys had access to lab equipment microscopes and press. He determined that the Chinese levers were higher quality than the OEM levers.
Here's mine for the 14

The results are just about in at busa.org. they have a engineer member doing some independant testing pazzo v Chinese levers (we have dubbed them "Chazzos"). The Pazzos are about 3.5 grams/lever lighter than the China levers. The guy is testing the standards; not the shorties. He suspects the Chinese levers will be stronger. They are thicker than Pazzo which prolly explains the additional weight. I can't wait to see what he comes up with tonight after running the numbers.....he said he is quite surprised, himself.
I'd love to be able to list Pazzo in my list of mods but for the money, I'm sticking with Chinazzos. They seem to work for the busas...still have to wait a little while to install on the 14---chain sprocket work is priority now.

I put the Chinazzo clutch lever on tonight. Fits great. I am just the slightest bit concerned because some people have complained that after market levers cause clutch damage.
This Chinazzo has a small divot where the clutch pin goes and it seems like it could have been a tiny bit deeper. It seems like the pin is pushed in a little bit all the time, even if the lever is not pulled at all. The OEm is the same but I do not believe it is pressing the pin as much
My fear is that this new lever may not be allowing my clutch to fully engage engine to transmission (like riding around with the clutch lever pulled a tiny bit---preloaded). Is there any way I can test this?

I've heard of a simular problem on the ZRX board with these levers. I believe they just drilled the whole out a little to allow the pin to fit it correctly.
Rook, how many people need to say that they had an issues with those exact levers? I understand your concern but I promise you that your clutch is slipping just a bit. The only way I figured it out was because my bike was down on MPH at the track and my 60ft times were horrible. You asked for advice/opinions and disregarded the opinions givin. I told you I had a problem on two different ZX14s so good luck!!! I don't think you would even notice it street riding unless you hammered the gas which would cause it to slip. I just don't get it man!!!! 32 hits on a lever question...I just beat my nuts flat with a rubber mallet!!!!

I don't think we established that these are the same levers as anyone else had purchased in the past.. far as I know. Me and jlewis are the only ones who have bought these recently and I do not even know if they were the same manufacturer. Mine were The2wheel.
Looks like the same issue with piston rest as others have described. Just looking for confirmation. I wouldn't bother if I were disregarding what was already said.
BTW, Sorry about your nuts.
I'm looking pretty hard comparing fit and movement to OEM lever.
As you can see, the Chazzo has worn into the brass and even a little bit into the sharp edge of the alum. The piston pin rubs.
The bottom of the piston hole is cone shaped from a drill bit tip. OEM has a flat bottom to the piston hole and the pin drops in there perfectly.
The brass pin rest part comes out easily enough if I wanted to drill the hole deeper. Just use a needlenose to pull the spring clip. ..but I don't know if it is a good idea to mess with the design.
Does the Pazzo lever also have the brass insert with drilled, cone shaped bottom of hole for a piston pin rest? If so, I guess this is no dif than using a Pazzo.

"Those levers on EBAY will not allow the pin to fully extend which in turn causes clutch slippage under a load. For street riding you would not notice it but it would wear a clutch out fast, espeacially once it has a little wear on it. I pulled my clutch cover and tried to push in the release bearing and could not even do it with those levers on."
Leo. Looks like your first post on this thread describes EXACTLY what is shown in the photo above of the wear pattern. This was after about 30 squeezes of the lever.

Actually I missed my nuts barely!!! It sucks about those lever because the quality is really nice and I really wanted to use them. On a street application I would just dremel the hell out of that hole and call it a day. You should be fine, but have a good day man.

Well, it almost looks as though the flat front of the lever is perfectly perpendicular to the piston pin. If I put a blob of hot glue on the bottom of the brass to hold it from turning in the lever while I drill, this might not be too difficult. Line up a drill bit, same size as current hole, sink it a little at a time and then test it on the bike.
Sits stable and looks perpendicular to pin travel when set on front of lever.
Couldn't ask for a better surface to support the piece while I drill press it.
even so, it starts to become apparent why most people would rather just pay the price of a Pazzo rather than screw around like this.
Now that I think about it, I remember seeing pics on zx14ninja.net (before they pulled the plug). Some guy had the same pics I am showing. Wouldn't the manufacturer have adjusted the CNC program by now? I guess we ask that about a lot of aftermarket parts. A bit of a challenge for a manufacturer when they produce stuff for so many models/years/make.
