fuel mixture screw fitment

Hi there, does anyone know if the fuel mixture screw is the same on the yz400 and the yz426 im looking for a after market easy adjust one and all the ones on ebay are showing yz/wr426, yz450. I assumed they were the same as the OEM parts finder site i was on showed matching part numbers for the fuel screws on yz 400 and yz426. I just found one ebay auction now that says "Will fit all YZ/WR 250F, 400F, 426F, 450F" that was one auction but allthe others made no mention of fitting yz 400 i know its old but its not extinct yet :bonk: heehee

Hey Tam,

Yes it will as they are carb specific and not bike model specific. (Keihin carb).

thanx im buying one now....

cool! Make sure you keep an eye on the 'o' ring when you install, and tune the screw around 1800 rpm, warm engine. Whats up with your avatar, looks like you got hit by a train!!!

that was a snowboarding injury in the canadian rockies(2 broken arms, 4 broken bones) fun times.......i could be late for anything because i didn't have a watch and couldn't open doors well haha

.....took a guy to the emergency room last year, after a nasty 'loop out' over a double at our local track, he definitely had 1 broken arm as it looked like a crooked limb, when he complained that his other arm felt sore too, the Dr. suggested another xray as long as he was there, wouldnt you know it, 2 broken arms. The nurse came up to me later and said "I hope his wife loves him", as I didnt quite know what she meant until I thought it through, and then I figured it out when he came out of triage with two casts on his arms and said "geeze, I sure gotta go to the bathroom"!!!!!!!!!!!!!!!

haha thats funny because after i woke up from being put under to put my arms back in place the doctor starting saying "so do you live alone", "do you have good friends here" ...etc etc....finally he got to the point and my friend beside me starting laughing and said apprehensively "i'll help her" it was funny but in the end I was fine to do all that myself albeit just a little slower ...I could't wear button flys for a long time though......haha

well see, you have very good friends, because when my friend said "I have to go to the bathroom", I replied "hope your wife loves you, cause I only like you"!! Then I ran out of there and left him to fend for himself (just kidding). We work together and I think he was off for like 4 months. He still has 'post dramatic ride syndrom' my word for relunctancy to ride again. 1 steel plate and 4 screws to hold it in. But on another note I did both of my knees (ACL's) 4 years earlier, so we are both gimps haha. Jeff

Button flys are so passe, I think they went out with nylon parachute pants. hahaha
