Clutch question for RAC4IT

When you had those clutch lever rods break on you, did you inform Muzzy? and if so what did they say?. I ask cos my friend FK has just has his break on him aswell. I was all set to buy a lock-up too but I aint paying $550 for something that dont work.

I emailed Doug Meyer at Muzzys about it, no response from him yet. They are aware of it and Ryan Schnitz told me that He and Chip Ellis both have had the same thing happen and keep stock of the puller shafts on the truck! When I broke my third at Maxton I decided that was enough and sold the lockup. Went 204 without it. Went 8.85 @ 161 without it. Muzzys normally gives excellent support so this is kinda surprising that I'm not getting any feedback on the lockup. So I sold it and wasted the money on the trip to Rockingham which got rained out.

What Bergie did not say, it really happened at a very inconvient time! He had to pull out of line and not run during the best time of the day!

I think to be honest a stronger part needs to come with the kit. You can see the stock one is too sharp edged and brittle to take the extra tension against it.

Mine was already very slightly chipped from running the HD springs.

If enough of us tell them about it maybe they will fabricate something to sell with the kit.

A picture is worth a thousand words..

I spoke with a machine shop about making a billet steel replacement but it's too expensive (in excess of $100 per unit).

Just my opinion but...I think part of the problem might be...since the Muzzys clutch pack is thinner...the puller is at a different angle pulling on the pin...it side loads the pin some...which might stop it from spinning (freely)...
It's pretty obvious (by the melted metal) that the puller-pin/rod is spinning through the clutch puller...

John's did the same thing...TWICE...
After I replaced the puller AND rod at the same time...AND keep the clutch pack thicker (than the out of the box Muzzy kit)...we haven't melted one since...KNOCKING ON WOOD...

Once again...the LOCK-UP CLUTCH...will put INCREDIBLE pressure on the pressure plate at high revs (input shaft speed) so...IF you try to release the clutch (pulling clutch lever in)...that WILL PUT INCREDIBLE STRESS ON THE CLUTCH RELEASE PARTS!!!

I run 11 steels not the standard 10 on mine, so I don't think that was the issue. But if it's working for you, awesome! FWIW, mine wasn't breaking on the strip, it would break in the parking lot or on the return road. It only broke once while actually making a run.

Or waiting in line! Bergie, How do you shift! "Air" Quick Shift, or manual??

You know why I asked! It did not look like you had anything "Other" than your foot! If you used the clutch, Bingo for the reason!

Ya know what guys, what I find EXTREMELY odd about the picture of the broken puller shaft up above is that my buddy Dave was experiencing that EXACT, and I mean EXACT same breakage on a freakin' 1995 6R that we drag raced a lot, but it was primarily a street bike.
It had stock clutch parts, but gearing, pipe, jet kit, lowered, etc.

We broke about 3-4 of those suckers in normal street riding and NEVER DID FIGURE OUT WHY!!

I just assumed it was a "mis-alignment" of parts. He even bought a new hub bearing and the needle bearings in the clutch cover!
Never did fix that POS............traded it in on a new 2002 Orange 9R though.

I would think that using the clutch would do this sort of damage...and NOT using the clutch (ie powershift/airshift/throttleblip) would not even make the puller shaft come in contact with the lever thingymabob.

Dont you actually have to put pressure on the clutch to have the puller shaft and the thingymabob touch with any sort of force?

Small question, if you aren't supposed to use the clutch then how do you launch? On my turbo, i have to be above 4K at launch not to run the risk of bogging and turbo stall.

This is what muzzy told me, that it was not for street use and downchanging using the clutch etc was a no no.

Bergie,Doug Meyers told me that your airshifter worked perfect now(I guess perfect means you took it off the bike and through it in the garbage)!What I have learned is the shifter will work fine on a stock or around 200hp bike but after that it will miss shifts.I sure wish Muzzys would of tried to help with my shifter problems instead of insisting that i was the only one in the world that was having a problem!
MTC has a killer lock-up that is streetable and they modify your cover with a bearing so the shaft has support.Anyone else notice Chip ellis's bike doesn't have a muzzy shifter and they run the MTC lockup.The only high hp bike I seen at Gainsville running the Muzzy shifter was there shootout bike with a modified tranny and higher pressure regulator.

AIR SHIFTER PROBLEMS


Bergie,Doug Meyers told me that your airshifter worked perfect now(I guess perfect means you took it off the bike and through it in the garbage)!


Dan you're right it works great now because I'm not using it! I've been foot-shifting all Summer and glad that I did because getting solid 8s without it was satisfying.

Actually I spoke with a guy at MIR during the weekend of Gainsville and he told me how to fix the problems! He said that he encountered the exact same problem with the Muzzys airshifters on two of his own bikes and a customers bike.

The problem is two parts- the pickup tube in the CO2 or N2O bottle and the angle of the bottle. He told me to goto a paintball supply shop and get an "anti-siphoning pickup" because liquid CO2 or N2O is getting into the solenoid. He also made custom brackets that support the nose of the bottle at a slight angle to make sure you're only getting compressed air. He claims no problems ever since.

Combine this fix with disassembling and cleaning the solenoid itself as I demonstrated on my website as well as shortening the air lines from the solenoid to the shifter as recommended by Jason Miller and it should work! At least it was working for him and his customer and I saw them running all day with it no problems. In fact he showed me a 10oz paintball bottle configuration that they were using for TWO MONTHS of drag racing without re-filling.

I haven't tried to apply these fixes to mine yet. I'm going to wait out the season and work on it over the winter. I'll keep you posted if these fixes work for me.

That was done by Lee's Performance prior to installation and yes I gather that is exactly what the holes are for (oil return)

Whats wrong with liquid in the solenoid? Thats a good thing (when it comes to spraying nitrous anyway) Liquid is better than just gas

Bergie,I don't believe that is the problem.My bottle has no Syphon tube and i have also tried teeing off my nos bottle which is spraying liquid with no difference.This may have you saying that i need to clean my solenoid because it could be gumbed up with the liquid but i sent the whole shifter back to muzzys and they installed it on a bike at the shop and it supposedly shifted flawlessly.My bike will shift everytime untill i start spraying it.I just wish Muzzy would acknowledge the problem with bikes running over 200hp.Did the guy you met from MIR run nitrous??
