  1. Don't know if you have tried this. Unhook the light blue wire from the CDI box. Doing so will give you more spark.
  2. If you haven't already go on ebay and order the hole kite for 65.00 from Hot Cams. this way you will have all the sizes to get them just right. Take your time on the change of the cam. I just did mine a few weeks ago and love the change. Follow the directions to the T its pretty simple.
  3. Texan, I just did my cam mod this week. As you I spent a lot of time reading other notes. I spent around $200.00 on mine. I ordered a 450cam od ebay w/ shipping was $105.00 I then ordered a kite of shims of ebay for $ 70.00. both came in in Friday. did the mod on sat. 2 kicks fired up. Its GREAT. on the sprocket the cam is ready to drop in.If you read old notes you will see that you may have chain ware. it will depend on your riding as to how fast or if any.If you change the chain the you will need to change your other cam. all thats not Worth it to me. The only issue I ran into was getting my shims right. Every installment including Yamaha's tells you to put the shims in the bucket then install. If you don't get them in right then you may end up with a bent valve. I set mine in on the valve then snugged the cam cover down and checked. if it was not .20 - .25 I repeated the proses. It may take longer but like I said 1 kick. good luck on yours.
  4. OK guys I got my cam and shims and am ready to the upgrade. But thinking about it last night and re reading alot of the post. I'm not sure why you need to measure the valve clearance before removing the old cam? seems to me if your installing a new cam it would not matter what the old cams clearances are. Am I not thinking of something?
  5. Thanks again for the help:thumbsup:
  6. thanks for the reply. How did you determine your shims without the right gauge numbers?
  7. Ordered all my parts last week , should be in this week. However after reviewing the valve adjustments I checked all my filler gauges and found out none of mine match the books mm numbers. the book on the exhaust stats 0.0079-0.0098in or 0.20-0.25mm all my valve gauges start w a (.) not a number. I checked the clearance anyways and a .008in/.203mm fits snug. is there a difference in bike gauges and auto? of am I not understanding. thanks.
  8. Thanks !!! Everyone for the replies. I'm going to order today and go for it. Let ya know the out come when I'm done.
  9. Thanks for the reply! Did you us a Hot Cam or a Yamaha Cam? I found a New Yamaha Cam on Ebay for $105.00 Not sure what one to use
  10. Mark I am thinking of doing the cam change on my 02 YZ426f also. Why did you go with Hot cams in Lu of Yamaha's cam? I'm trying to find the best way thanks KEG
  11. I have a 2002 YZ426F and have read a lot of the old postings on the exhaust cam change. I am looking for any new replies and also trying to find out if it matters or not if I have Titanium Valves. And for sure if they will require shimming. any and all newer info and photos would be great. Thanks! Keg6262
