  1. Hi Guys, I sincerely for your replies. This forum is great.
  2. I removed the right crankcase cover of my 2002 YZ426 to replace the water pump impeller shaft (impeller would not unscrew). I noticed that along the top inside rim of the cover there was what appeared to be a machined groove, or more of a band of metal that was machined off. I assume this was caused by the clutch. I'm the second owner, and have no idea if the clutch has been replaced and perhaps installed improperly. The machined area looks to be about 4" long x 1" wide. Has anyone ever seen this type of thing? Thanks for your help. I've never tried to attach urls to images, but the urls are as follows: http://tinypic.com/view.php?pic=25gzbiu&s=4 A close-up of the area of damage is at: http://tinypic.com/view.php?pic=34e280z&s=4 The "machined" area is silver, and the normal areas are darker grey.

    Fuel Screw

    Like flintlock28s response above. Just to add, I just received a Zip-Ty fuel screw from JD Jetting. Same concept as your MSR. JD recommends to seat it (screw it in all the way), then back out 1 1/2 turns. Then start it up and fine tune with 1/4 turns in one direction, blipping the throttle at each setting.
  4. I stumbled into the WZ forum and found the following message posted there. I thought my fellow YZs should benefit too, especially those without manuals. The link referred to in the message below didn't come through in my cut and paste. The link is http://www.yamahaownershandbook.com.au/?r=0. Kevin Posted by Clark4131 in WZ forum: Free Yamaha Manuals On .PDF Since a lot of folks want to get a .pdf version of the manual to save on their computers, here's the link to where you can find them. They're from the Australian Yamaha site, but this link will take you there without having to search. Keep in mind however, they are the international versions with French, German and Spanish supplements. You can edit those pages out if you have a password removal program and Adobe Acrobat. IMHO, these are actually better versions than the US, as they have tuning sections in them that go into proper carb adjustment, engine management, etc. that are omitted from the manuals given out in the States. Enjoy ...SC
  5. Hi Guys, thanks for the replies. I've seen blow-by out the radiator cap within 15 seconds of starting up a cold engine. The header is within 1/4" of the bottom of the radiator, and I think that focal area of heat steams things up quickly, builds a quick spike of pressure, and blows a little fluid. Air flow of course is the trick. I just wondered if anyone knew of something that would act as a heat shield for those times when I want to stop for a minute on a trail, or work for a short while on the carb with the engine at idle. Thanks again. Kevin Encinitas, CA
  6. Can anyone please suggest a simple heat shield design/material to stop heat from the header from boiling the coolant at idle? I'd like to stop along a trail for 30 seconds or so at idle without loosing coolant. I also worry about heat damage to the rubber radiator hose that's so close to the header. There's various insulation materials that could be wrapped around the header pipe, but this would look pretty tacky. I'm wondering if there are some other more clever things that others have used. Thanks.

  8. I'm a newcomer to dirt biking, and to this forum. For the last year, I've owned a 2001 YZ426. I've adjusted the valves and performed other things that I never would have attempted without the benefit of this forum. So I am grateful to those who take the time to post. I don't know how many readers out there might be interested, but I recently came across a web site that contains .pdf files of factory parts catalogs for what seems to be all Yamaha products. The site address is: http://www.yamaha-motor.com.mx/Manual_Partes/Catalogos/. It's apparently based in Mexico. I found the YZ426 under the directory "Competencia". As you may know, the Yamaha corporate web site (http://www.yamaha-motor.com/sport/parts/home.aspx) also provides access to part catalogs. I find the catalogs useful because I can print out a page with an exploded view of the assembly that I need a part for. Helps take the guess work out of defining the exact part you need for the parts guy at the local shop. But logging in is a pain, and I don't find the site that user friendly. Now that I've downloaded the file for my 2001 YZ426FP, I don't need to hassle with the Yamaha site. It also comes to mind that when I read some forum posts, it's sometimes difficult to understand exactly what screw or widget is being discussed. For those folks who are software savvy, I assume that a jpg can be made out of a page from the .pdf parts catalog. By attaching the page/jpg to a message, it might be easier to articulate exactly what part - or order of assembly - is required.
