clutch squeel

[onegreyghost]

Hey guys the sixdays is running great. I have a friend who has a 2010 gg 300 that the clutch squeels when the bike is under a heavy load such as when your a gear to high say 3rd when you should be in second. When you slip the clutch a very high pitch sound occurs. Anyone one here familiar with this issue. We changed the brand of oil from shell rotella 10/40 to maxima straight weight 65 and it still makes the noise. We called go fasters and they have heard from a couple of guys. Will it hurt the bike?

It's annoying isn't it....Not sure why they squawk like that, I think it's a frequency type vibration that comes out of the plates.
I wonder if a stiffer spring might quiet that down.
In any case don't sweat it...I'm on my 2nd clutch, I changed it at about 60 hours and everything still looked new.
The basket, hub and pressure plate looked fine...I didn't see any sighs of wear or damage....so just ride it.

There may be some posi-trac additives that would stop the noise but I'm in agreement with others that say it won't hurt it a bit to squawk a little.

I wonder if you are putting a full quart of oil in the case.. My friend has an EC 200 and was using the sight glass to fill with oil. It was not enough. I always dump an entire quart into the transmission. Most any two stroke can handle 25% more oil than the manual calls for.

Clutch squeel

I was just wondering why some of the bikes would make this noise while other would not. The manual recommends 900cc's of oil but I believe he is putting in 850cc's because he is a trials rider and people who ride trails recommend putting in about 50cc's less that what the manual recommends. We will add about 100cc more to get it to 950cc and I will let everyone know if that helps out with this annoying noise

Mine does it when I am abusing it (steep hills and slipping the clutch). I just figure it's a warning sign for me to ease up a bit.

Is he running a full synthetic oil? My old Husaberg would squeal like crazy running full syn oil. I went back to cheap dino oil and changed it frequently and the squeal went away.

My 04 model did that until I changed to the rotella. The 07 never did it. I always used just one quart of oil.

Clutch squawk

I am someone who really abuses the clutch, especially hill climbing. I am talking about the bike is bouncing off the rev-limiter and at the same time letting the clutch slip. I dont get the squawk that he is experincing when he is running the bike moderatly. We rode last week and I done some hill climbing with his 300, I thougt the engine was going to disintigrate under neath me. The sound horrified me, but if its not going to damage the bike then I see no reason to pull it apart. I was just nervous because the first engine in my 300 ate through the engine case because a clutch issue. Anyway here is the oil he is running in the bike. Its maxima MTL Trans/Clutch Fluid 75 wt. Here is what the bottle claims-MTL has been significantly improved with new technologically advanced additive systems that drastically improve clutch life and reduce slippage. While accomplishing this, MTL provides outstanding anti-wear protection and lubrication to the transmission as well. This new formula has been extensively tested on the race track by many of the nations top mx teams and tuners and is now available to the serious competitor.

I would stay away from any 'special additives' oils and stick with a full synthetic oil if you abuse the clutch. Like Motorex
A guys I ride with is like that. Right hand is locked full open and the clutch is being punished all the time.

Put in the full 900cc. Change it lots and Call her good.

Generally speaking.. never put in anything that says "energy conserving" on the label....lots of the good stuff like zinc and phosphorus are removed for extended life of oxidation catalysts......some even have moly added...also not good for a clutch...

like HD says stick with a recommended oil for a 2T gearbox it will have the correct additives....not too sure about going heavier than GAS GAS recommends....I personally stick with 10/30

looks like got us a bonafide oil thread going here.....

clutch squawk

I run atf automatic transmission fluid in my 300 raga trials bike. Talk about clutch abuse. Has anyone on here ran it in an enduro bike. Do u think it would hurt it. Must be good stuff because car manufacturers don't recommend changing it but every 50,000 miles. Automatic transmissions are full of clutches that are made to slip

You are giving me Deja Vu.

My 2010 300 squealed like a stuck pig. I run a full quart of 15w40 and also tried a couple of different oils. I am hardly a clutch abuser and my other bikes have never done that, riding the same trails.

I ended up putting a Rekluse in, problem solved.

 

[roostafish]

I used to run ATF in my bikes 'til I could afford gearbox oil. That's what my dad ran, and we had quarts of it on the shelf. We never had clutch issues.

As one guy once said: "How do it know?"

I emailed the guys at the factory about this. They are on holidays this week so I don't expect a reply until next week. Those guys have more holidays than work days!
BTW....I had a little bit of clutch squeal on my 2010 nambo but it went away after a few hours on it. I use Motorex 2T tranny oil. I really like Motorex products.

That's great to have you plugging into riders feedback!
I have an 08 EC 300 and 2 buddies I ride with have 09's, all 3 of our bikes have squawky clutches under heavy slipping.
I use Belray gear oil 80w, one guy uses the Honda brand trans oil, and the other uses Castro GTX 10w40.
I don't think it's an oil issue, it's something in the clutch design it's self.
My bike's clutch squawked with the stock plates/springs and still squawks with the Moose kit.
It also could have something to do with the torque the 300 produces?
