    2008 YZ450F Slipping Issue

    Grayracer, Thanks for the response. There is some free play of the clutch cable, as determined by some wiggle room of the clutch lever before I begin to feel the resistence of the clutch springs. The amount of play (i.e. distance of clutch lever movement) obviously depends on the distance from the pivot point, but there is probably 1/4" of play in the lever in the middle. It's about the same amount of play as I've always allowed. I did read another one of your posts where the heating of plates, subsequent adjustments to compensate for it, and then the lack of readustment once the plates cool can cause premature wear. However, that's not likely my issue as I rarely adjust the clutch - it's normally fine exactly where it is. With that said, I'll go back and check it and probably add a little more wiggle room. I'll change the oil again, just to be safe, and see if that fixes the issue. If that doesn't work, then I'll repalce the clutch plates and springs. Does that seem like a reasonable approach? Could I have caused the clutch plates to harden by letting the bike sit without oil for 5 weeks? Thanks again, J
  2. Hello all. There are a number of facets to my issue, so please humor me for the long post. I rode my 2008 YZ450F yesterday and noticed that my clutch seemed to engage further out than I expected it to. I haven't ridden much in the past 12 months so I do not have a great reference point to describe the change. I estimate that the clutch begins to engage when the clutch lever is approximatley 75% let out, rather than the 50% or so I normally expect. (I didn't notice any slippage issues the last time I rode, which was about 1.5 months ago, or any of my other 5 rides in the past six months.) Additionally, while I was riding, I noticed that when I got on the gass the engine would rev and the bike would accelerate, but it did not pull like it should have. At first I thought the rear tire may have been spinning since the track was a little dry and hard, but then I noticed it in the softer sections too. The bike did go, but it did not seem to fully engage. However, there are two additional pieces of info that are probably relevant: 1) The last time I rode 1.5 months ago I noticed coolant leaking from the water pump weep hole. When I got home I washed the bike and my four year old daughter "helped" me. When I went to get something from the garage I came back and noticed that she was at the rear fo the bike with the hose and I didn't have the plug in the pipe. She admitted that she put water in the pipe. (I can imagine from her perspective that it seemed like the perfect place to spray some water!). I don't know how much she put in. After it was washed, I tried to start the bike to flush out the water but it wouldn't start. In retrospect, I should have taken off the pipe to drain the water and inspect, but I didn't. (Insert clever emoticon here.) I drained the oil and antifreeze in preparation to fix the water pump leak issue. 2) On Saturday night, my buddy came over to help me replace the two seals, bearing, and water pump shaft that was causing the original leakage from the water pump weep hole. (Thanks again, Brandon, for your help and to Grayracer for posting what needed to be done.) When we removed the pipe there was water in the low section of the header pipe, which I emptied. Other than that, we didn't notice anything wrong and the job went well. Since the right side of the case was was off, we inspected the clutch basket and there was no cupping (or whatever the real term is) to speak of. We reassembled, refilled the fluids, and went to the track the following day (yesterday). When I got to the track the next morning, the bike started just as it normally does, so I figured everything was okay. It was not until I hopped on the bike to take off that I noticed the engagement issue, and then noticed some apparent slipping while riding. BTW, I rarely use the clutch and I never feather it to control power. I use it to start moving and to shift. So, there are a number of factors that happened that cloud the issue for me. I'm not terribly mechanically inclined so I'm in need of advise on where to start investigating. My thoughts: 1) There was some residual water that leaked into the case that caused the slippage issue. Change the oil and try again? 2) The clutch plates / springs need to be replaced. (It may have been an issue for some time that I'm just now noticing all of the sudden, but this seems unlikely.) 3) Transmission is going bad all of the sudden - although I've never noticed an issue before. 4) Other???? Thanks in advance for recommendations on how to go about investigating / fixing. J

    San francisco sx race links

    My AT&T U-verse still isn't showing the 450s race today at 11 am CST...and that's only 35 minutes away. I hope that this is just a program schedule mistake and that the 700 Club telethon really won't be preempting SX...I would be so disappointed!

    Dungey, lookin Fr3$h

    I'm with ChadK66...RD wouldn't need any help. I bet RD didn't even make the call. As soon as Fox heard RD wasn't happy with his ONE contract, they were hitting the speed dial to get him on the phone. You'd be crazy not to try to get the top lites class rider in your gear! I bet RD got calls from everyone. That's biz folks.

    Dungey, lookin Fr3$h

    Obviously you're entitled to your opinion, but I completely disagree. If he bitched about it and told One to drop J-Law and keep him, then I would agree...but he didn't. He acted like a man. He confronted the issue rather than running from it. He dropped the contract, (and must be dealing with some penalties for breaking his contract, but isn't whining about any penalties), and got a different deal. That's dealing with the situation like a man...not a little girl. Too bad though, because his gear last week looked much better than the Fox gear shown in the link above. JB

    yz 450 title ?

    I wouldn't want any chance of any time in any prison. Perhaps you're not familiar with what happens in those places!

    2008 YZ450F Radiator Question

    Thanks for all the help/info. I checked out their work...impressive stuff. I'm not sure how they do it, but it's pretty sweet. I ended up buying a new left side radiator, but I am going to have my old one fixed too. My mechanic here in Austin is very good at fixing anything...so I'll see what he thinks. If he can't do it, then I'll send it to Mylers. I'm not sure why I didn't think about letting my local mechanic give it a shot before I bought the new one. I'll be surprised if he can't fix it, but it doens't hurt to have an extra one laying round too. Thanks again, Jeremiah

    2008 YZ450F Radiator Question

    Thanks gray. I'll give them a call. I'm curious to know how they could straighten one out. That seems difficult to me, but I'm open to anything. JB
  9. Hey gents (and perhaps ladies)... I bent up my left-side radiator during a get off the other day. I was looking on eBay to see what was available, and found a couple of new radiators from independent sellers, both with good ratings based on thousands of feedback responses. For example: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=350138433652&ih=022&sspagename=STRK%3AMEWA%3AIT&viewitem= and http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=200288934185&ssPageName=STRK:MEWA:IT&ih=010 Anyone have any experience with anything like this? I'm inclined to give one of them a chance based on the feedback scores, but thought I'd check with y'all first. Actually, I haven't called the Yamaha dealer yet, so I first need to see what they're getting for OEM radiators, but I'm guessing they're 2x the price. Anyway, thanks in advance for any input. JB

    08 frame changes?

    I read the yama website, but don't remember the details. I just wanted to say that Langston is not short on complaints...never has been.

    Is a brand new 2005 YZ450F worth $4999?

    You can buy an '07 for $5,300-ish. (Seems too good to be true.)

    help for skid plate install on 426

    My skid plate has three bolts and spacers between the plate and the bike's frame. Sorry, I'm not familiar with the one you purchased. Perhaps they can order the one you originally wanted.

    Question about DB Dawg...

    The insert shouldn't have anything to do with the smoke and black soot. It's likely that your valve seats leak based on the age of the bike. I have a 2000 YZ426 too and I've got the same issue. If the bike sits for a while then it smokes when I start it up as oil has leaked past the seals and into the chamber. The oil burns off quickly and after 30 seconds of running the smoke is gone and does not return. I read your post because I wanted to know about the db DAWG. A track being built near my place is gonig to have AMA sound restrictions and my Dr.D exhause certainly won't pass right now. In fact, I doubt anything will help it to pass, but I'm curious to know how much the db DAWG helped reduce your sound level. J

    New 02 426 project

    I'm always so impressed with grayracer's knowledge. What a good man to share it with everyone!
