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.

^^^ To the rescue!

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

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?

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.

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

Going to first gear from neutral/park requires the input shaft (which is spinning at engine idle RPM when clutch is engaged) to match speed with the stationary gearset in the transmission without any output shaft speed (vehicle not moving) which is very difficult to do without the clutch operating correctly by relieving the drive speed from the input shaft. Whereas, shifting between forward gears with both input and output shaft speed already in motion is far easier, therefore requires the clutch to function less. In a synchronized gearbox the synchros themselves will do a lot of the speed matching, but it takes a toll on them much quicker without the clutch releasing correctly.

It's the same reason you can technically shift gears without a clutch if you're talented at timing shifts, but you still can't get it moving or into a motion gear happily if it's not operating correctly.

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.

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

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?

It was just a tiny internal leak. Not sure how to explain it, but replacing it fixed the issue. And it only affected the car when it sat for awhile. Like when I would come off track then first gear was fine again.

That sort of makes sense, but, is it possible new fluid and bleeding fixed the problem

It was just first, slippage and hard to get into 1st, but the new master fixed it.

[Arizona Vipers]

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.
