water pump and trans squeal

Recommended Posts

WOW, i just picked up a new 06 450 and mine is making the same noise and is also lunging forward. i have ridden mine twice, the first day i heard the noise and then it went away,yesterday i pulled off the track heard the noise. i put it in neutral and it was making the same noise, i blipped the throttle and the bike jerked forward. i shut it off and restarted it. the noise was gone. i rode the bike 3 more motos,,, no noise. a friend said he heard three other bike make the same noise. i called the dealer and they said they have never heard of this. my fear is hitting the face of a big jump and have the tranny lock up,,, wouldn't that be fun? i am taking mine back to the dealer, but my fear is that they will not get it to make the noise.

Everyone says to add 40-100cc of oil and it will go away (as long as it was not the same problem mine had).

I am running the extra oil in mine just in case though.

Let me know if it stopped your noise if you choose to try this.

my 06 does the same. I have learned to ignore it. You should see the looks I get at the track when it starts squeeling

I am sure that McGrath or Windham would not be impressed if their factory bikes started "squeeling" and pulling ahead on the line while warming them up in front of the tv cameras. Great advertisement for Honda. I would imagine Chad Reed whould fall off his bike laughing! Why do some do this, and some not, and what fixes it permanently? The 40cc of extra oil?

UPDATE: I did put exrta oil in my trany and went out to the local moto track today. I didn't hear a peep out of it all day, but it was in my mind when I was hitting the 70' double. Anyways, I really think the idler gear making the noise is not true and tend to believe the main or counter shaft gears binding on the shaft to be more of the real problem. The idler gear wouldn't make the bike move in neutral. As for the extra oil??? I still want mine torn down and Honda to flip the bill.

My dealer is putting my old one back together. I am curious to see if the problem was solved. Will keep updated.

If there are so many people with this problem, why does Honda deny knowing anything about it?

My brand new 06 did this in the first 15 mins of break-in. I added some oil and it seemed to go away. I still hear a little squeal though, but not moving forward in neutral anymore. Adding 40cc more from what? What is the total CC's you are running?

Id be willing to be the original problem was the tech that filled the trans the first time. I bet he filled it up, checked the oil level screw, oil came out and he was probably 300cc short of oil.

There is a procedure youve gotta use to check the oil level in the trans using the check hole.

Thats why its a hell of a lot easier to just pour in 625-700cc of oil and be done with it.

Shawn - how many times would that statement have been made in the CRF forum? It's got to be the most common statement made.

Measuring and just pouring in the oil is the only way to go for safety.

      I just bought a Magura hydraulic clutch for my 2014 CRF450R.  Bought it thinking install would be easy, and I'm not sure that's the case now that I have the product in my hands.  I have searched the forums, YouTube, etc for install help specifically for my model year (2013 and 2014 are same really), and haven't found anything specific for the 2013-2014 model install at all.  Instructions from Magura are TERRIBLE, and are not specific at all to the Honda - generic instructions - so I'm debating if I want to return the product, cuz I don't want trouble or a big install job.  Question: for the 2013-2014 CRF450R install ONLY of a Magura Hymec hydraulic clutch - other model years are different and thus it won't be helpful for other model years - do you have any tips or feedback?  My concerns are below...
      1.  The 2014 model has a sleeve behind the clutch actuation arm that the Magura clutch slave cylinder fits into.  Stock, the sleeve holds one end of the cable, with a nut on the other end to keep the cable end tight in the sleeve.  The Magura slave cylinder, however, slides into the mounting sleeve  - but does NOT have a nut: the tension from the clutch actuation arm pulling on the metal Magura slave cyl tip end is apparently supposed to keep the Magura slave cylinder tight in the mounting sleeve.  Q: Will the Magura slave fit in to the mounting sleeve easily, stay tight, and is there any adjustment needed in order to keep the 4-6mm of freeplay that Magura recommends?  How easy is it to get the Magura slave fitted into the sleeve and the metal tip in place?  Is there enough freeplay between slave and tip end to mount in actuating arm AND the holding sleeve, so that the holding sleeve doesn't need to be unbolted?  
      2. The stock clutch cable and OEM setup runs out of the mounting sleeve (see pics marked "metal starts", and then runs through a metal sleeve that routes the cable through the engine compartment - keeping the cable away from the hot parts of the engine case, so as not to melt the cable insulation (I believe).  That metal sleeve is about 6-8 inches in length.  The Magura clutch cable, on the other hand, exits the Magura slave cylinder at an angle - yet has no such metal routing.  I don't think the OEM metal routing sleeve will accept the Magura cable either, so a) the OEM metal routing sleeve would have to be removed first before installing the Magura - and then b) you have to hope that the Magura cable can be routed in such a way with zip ties holding the hydraulic line that line will not touch or be close to the hot metal engine casing as you route it through the engine.  Q: how easy was it to get the OEM clutch cable and metal routing sleeve out?  Easy as unscrewing the nut on the other end of the OEM cable, on the other side of the black rubber cable flange in my pics?   
      3.  My stock clutch pull isn't bad.  I just like the feel of a hydro clutch.  Any feedback on how much better feeling and easier pull will be with the Magura?  What's your feedback on the difference?  FYI, I'm leaving my clutch plates and springs stock.

      We have a 2016 CRF450R with about 11 hours out. never ridden hard always check the oil and change when needed along with the air filter. Took care of the recall that was required as well. Well when riding the bike was stalled out. Went to try and kick start the bike again. the kick start lever just back up jamming my knee into the handle bars and some how ended up cracking the case right by where the kick start goes through the case. Has any one had this happen or heard of this happening? What is the cause?

      Any advice on what should be replaced while I have the top end off for a valve replacement. Will do headgasket and springs of course, anything other parts you would recommend while I'm going at it?
       
      Thanks!

      The dirtbike is on it's forth year right now on the same motor job. I have to jump start it. Is it worth me trading for a 2009 650 brute force with7000 miles? Need some expert advice. Thanks

      Just wondering what you guys do to remove black marks on your seat. My 08 crf450r has the red/black seat, and after each ride there are some black marks on the red from my riding pants. Not scuff marks, more like patches of black residue from my pants rubbing on the seat. I’ve tried the magic eraser which seemed to do the trick, but lately they seem like they aren’t coming off. Also tried scrubbing bubbles with a brush and no luck. Not too worried cuz I have an spare OEM seat, but I’d like to keep this one nice. Any ideas? Maybe I shouldn’t wear black pants?
