My car was in the shop since last friday, they did solid motor mounts, sold trans mount, and the street twin with adj master cylinder.

First observation, noticeable vibes from the solid mounts at idle and when starting in 1st, other then that it's pretty tame, I don't regret going all solid.

As far as the street twin, some things are bothering me and I hope someone can shed some light on some of these concerns of mine.

First, it appears that the street twin has the same pedal effort to push, however the "slip zone" is much smaller and when starting in first it is very easy to stall the car out if I drive it as if it where stock. Is this how it's supposed to be set up?? With a minimal "slip zone" and more of a GRAP type action??? I can still slip it just alot narrower band of play. I thought that this clutch would have a "stock" feel.

Secondly, i want to test to see if the install was done correctly, so i kind of beat on it a "bit" even though they say 500 mile break in. I did a few full throttle bursts and a 2k drop. The tires spun on the drop, however it seems that in 1st gear if i give it 100% I'm not spinning off the road. It could be me, but it seems like the clutch is slippin however i could be wrong. Any good way to test this??? I'm not really a clutch expert, so is there a way that the shop could have fubared the install so that the street twin is not grabbing 100%?? This is my major concern, thanks.

 

it sounds like you might be messing up your clutch by not allowing proper break in before abusing it. thats not the shops fault.

 

The street twin is a no-slip clutch. It takes some getting used to, but what you're experiencing is normal.

I wouldn't play around until the clutch is broken in. Do you really want to glaze over and ruin a brand new $800 clutch?

 

way to go on your brake in time!!

glaze over rules guys, didn't you know???

 

i doubt i glazed it over by going WOT a few times. It seems to be getting better as I'm getting used to it anyway. It's just I'm used to the stocker and it's taking some time to get used to it. And if i DID glaze it over how the hell am i supposed to drive my car for 500 miles like a granny, lol. Damn, it's TORTURE. Anyway, blah blah glazed, it's fine. If not I'll buy new disks, no big deal, live and learn It's not like I have to buy a NEW $1000 street twin, they sell the rebuilt kits for them. So I'm not 100% screwed if it's glazed.

I'm not a total goon, i went like 80% in 2nd and maybe hit it 100% for like 1.5 seconds in first. Not like I did a whole 1/4 mile run, . If the clutch will get glazed because of that then it's gonna get glazed anyway.

Also, there seems to be chatter, more so then the stock setup. Is this clutch just noisier or will it "break in". Thanks

 

i had a lot of problems at first with my street twin but it was mainly my fault when it was all said and done This clutch should not chatter at all and it should be just a little more stiff then stock. I would not get on it for the rest of the break in period. and if it still chatters there is something wrong with the clutch which may be your fault, unless it chattered since you picked up the car then its an install problem

I don't know if it's just me or the installation, but my street twin is WAY stiffer than the stock clutch pedal.

 

well, come to think about it, I did put in a SOLID tranny mount so that could be passing lots of vibes which could be mistaken for chatter. I'll baby the clutch and maybe I'll switch out the solid for a poly this weekend to see if that helps.

I don't know if I'm describing chatter accurately, what I'm trying to say is that it has loud "tranny growl" like when u take off in first but in 4th and 5th now. I'll attribute this to the solid trans mount. Well, I guess I will see in 500 miles when i put on the slicks if my street twin is functioning correctly. I know the clutch GRABS in first cuz when i let off the clutch it will just pull the car forward like no joke.

 

You're not describing chatter accurately. Chatter is a clapping kind of noise from the clutch on engaging or disengaging. It comes from a lack of cushion in the discback. I have chatter in my McLeod Dual Performance, because it uses cerametallic friction material. Your tranny noise might be the fluid (when the last time its been changed) or the solid mount. Also, the way the clutch is dampened (spring rates and such) will affect what noises you hear. The stock clutch filters out a lot of vibration and noise, but with aftermarket clutches you get different noises. Oh, and take it easy for the rest of your break in period. I have 380 miles to go on mine and its killing me, but I'd rather take it easy for 500 miles than tear down my trans again and buy another clutch set.

 

Ok, well then i'm pretty sure i don't have chatter. When i disengage/engage the clutch it's smooth. I'm talking about when the clutch is fully engaged, and i apply power at low rpm's i get a "growl" and shaking from the tranny.

I'll check the fluid and change to a poly mount, thanks for the help. And yes, I'll be easy on the clutch.

As far as the directions for the clutch breakin, all it said was "no HARD driving for 500 miles" To me that implies no 1/4 mile runs and burnouts, not that i can't go above 50% throttle and if i give it WOT for more then 5 seconds my clutch will melt, . Since it seems all of you guys say to REALLY baby it I'll try to do so. Has anyone glazed over a new clutch and how much "abuse" did it take to screw it up???
