wr 426 enduro gear change

Looking for some advise on my wr 426. Just recently got it plated so I can now run around the neighborhood legally:banana: Love my bike in the woods wish it was shorter or i was taller but thats another topic. Gearing is perfect for the woods but now that i am on the street sometimes the 60 mph runs seem a little to revvvy in 5th. dont want a sprocket change that will kill me in the woods. So that leaves 5th gear which i wish was doggin the bike a little more and increasing my speed. I know I know its not what Yamaha had in mind but it is what i am doing with the bike. Dont want to trade off for something else want to make mine better on the street and not effect it off road in gears 1 thru 4. gear change:busted: maybe. Do they make a different gear for it. talk to me people

You can have a suspension shop install spacers to lower the bike or you can purchase a lowering link. But first I'd make sure your sag is set properly. If you're at, say, 3.5 inches, you can get a half inch by putting in that extra to the recommended 100mm/4inch range. If you shave the seat do not take out too much; frame rails become your butt's worst enemy in a longer ride.

5'10 240 my butt needs no more enemies. sounds like one tooth in the front only. hmmm what about changing 5th gear. is this available? practicle?
You have a WR, so you already have the tallest 5th gear available. I put a WR426 gear set in my YZ426 as 5th in the YZ is lots shorter. You will have to deal with external sprockets instaed of internal ratios. I am pretty sure that the advice above will get you on a good path to finding the right final drive ratio. Front sprockets are pretty cheap (compared to rear sprockets) and you can fit up to a 16 tooth front, but only if you trim the chain slider where it wraps around the front of the swingarm. I have run a 16/40 combo (road racing) all the way to a 13/46. Lots of flexibility if you sort through a ratio chart.

Did you have to also trim or modify the metal case saver guard? Also, how much of a modification or trim did you have to do the the chain slider? As I stated above, I figured something had to me done to these two areas.
