Anyone got an Nth Moto clutch laying around

[Arizona Vipers]

******* EDIT: NOTHING WAS WRONG WITH THE NTH MOTO CLUTCH, THIS THING HAS BEEN BULLETPOOF FOR YEARS NOW! A GREAT PRODUCT! THE PROBLEM WAS A LEAKING MASTER AND/OR OLD CLUTCH FLUID)********
I've got an important track event this weekend and clutch is starting to slip. Nth Moto is at the texas standing mile competition but doesn't think he's got a triple in stock, just the quad. I don't need the extra weight of the quad. It's a million to one shot that somebody on here bought one to install and has it handy and can overnight it to me. It's possible that it's the slave cylinder as well, trying to get one of those overnighted as well.

Why would you think it is the slave. I could get you a slave if you do not have one.

In stock ready to ship anytime you need one call or email 775-857-1913 martin@tkomotorsports.com
next day air not a problem.

You have the Nth clutch in stock? The triple?
Here's the problem the car started happeing, on the grid, driving, hard to get into 1st gear. Then at times even pushing the clutch in the car would still feel like it was in gear. I'd run a session then after the session the car would feel fine, but then did the same thing when going back to grid the next session. Clutch is fine everywhere on the track, just have the problem in 1st gear on grid going slow.

do you bleed your clutch after track time? 20- 40 Min track time bleed clutch.

No I've never bled it. You have to pull the trans to get to it, right? You guys do this? I've tracked it for years never had to before.

[Steve M]

There is no bleeder screw on the Gen 5 with the stock slave.

[Arizona Vipers]

Yes we are a stocking Nth moto clutch dealer 3-4 gen viper triple clutch , 5th gen clutch calles crank or factory crank triple disc clutch in stock always.

Pully belly pan you can bleed factory clutch real easy. You dont need a piss cup just put rag and crack bleeder with some one pressing clutch. Top off reservoir and your all good. We bleed clutch on the viper track cars usually 20-40 min track time or 2-3 sessions same with brakes.

Do you have an aftermarket slave or something?

We bleed clutch on the viper track cars usually 20-40 min track time or 2-3 sessions same with brakes. We also us PFC 665 fluid, best brake a clutch fluid we have found so far.

While the slave cylinder/clutch line clip is disconnected, you have someone press the clutch to bleed?

Check the brake master cylinder reservoir fluid level, if necessary, add D.O.T. 4 brake fluid.
Release the retaining clip at the slave cylinder coupling.
Separate the line from the slave cylinder enough to create a leak.
Slowly actuate the clutch pedal until fluid flows from the open coupling.
Snap the slave cylinder coupling together until the retaining clip locks in place.
Actuate the clutch pedal several cycles until the slave cylinder releases and applies the clutch.
Allow the clutch to rest for a count of 20 to allow the fluid to stabilize.
Actuate the clutch to verify proper operation.
If necessary, top off the fluid level in the reservoir.

Those directions say to unclip till fluid flows then clip it back in then depress the clutch.

It would be nice to have a definitive answer about the proper way to bleed our slave cylinders. I have seen different people and manuals say different things.

Here's our transmission and the slave cylinder where the clutch line enters on the left side that TKO is talking about FYI. In this picture the clutch line to slave cylinder retainer clip is in the "up/loose" position.

No your right no bleed on 5th gen factory slave. We modded couple the 5th gen track cars so we could bleed the clutch
. My bad sorry about that. You can still bleed the clutch but you have to do it the hard way with the quick disconnect and its big mess and difficult which was the reason we did the mod.

Do you have any details about that or sell the modification? Sure would be nice to have a remote bleeder line or something to that effect

AZ, I realize it's a bit off topic, but understand that from the Mac forums that you're also bringing the 720S. Would love to hear you comment next week about the two cars. Good luck getting the G5 clutch replaced quickly!

Hey dude! I'll be running the 720 at AMP https://arizonamotorsportspark.com/ at the end of the month. The Viper won't pass sound there. This weekend just the Viper at Bondurant if I can figure out the clutch issue.

Could it be as simple as the fluid is old, has absorbed moisture and boils at the slave.

[Arizona Vipers]

Just an update on this, the problem was a master with a tiny leak. It was enough to cause the problem. It had been going on a long time and I didn't even realize it because now the clutch feels totally different, much better.

[Steve M]

Where was it leaking, and how did you find it?

[Arizona Vipers]

Internally. If you rested your foot on it with light pressure it would slowly go to the floor.

Interesting...that would certainly make disengaging the clutch a bit of a challenge.

The shop also took out the entire transmission just to bleed it. That fluid doesn't circulate much, I can't believe they made no way to bleed it.

I've always wondered how well the Gen 5's "no bleeder" slave would really work. Fresh clutch fluid is pretty important, especially on a car that's tracked hard.

I installed a remote bleeder on my Gen 4 when I put in the Nth Moto clutch just so I'd never have to crawl back under the car to do it again. The stock bleeder was a PITA to access.

Were your brakes affected?

[Arizona Vipers]

Were your brakes affected?

No, not that I noticed. But I only drove the car one session when the problem started on the grid before session and I only went 3 laps.

Clutch is fine everywhere on the track, just have the problem in 1st gear on grid going slow.

so is it slipping or hard to 1st gear or both? if all the rest of the gears work like butter, you have a bad pressure plate

[Nth Moto]

Glad you found the issue Cable, have fun out there!

[Jack B]

There are many confusing comments in this thread:

1. I have a hard time understanding how a bad master cylinder affects 1st gear, but, not "on the track" .shifting. Did I mis-interpret that statement?

2. In your comment above, I am not disagreeing, just explain?
