OK, so I 've had the WR for a couple of weeks. It ran so-so, and had bent and unfriendly controls, so I did some upgrades.

The JD jet kit went in, and cured all the running problems. Going from a 160 to a 170 main, and the Red needle really transformed how the bike runs. It will still bog if you go for WOT in low rpms, but you really have to whack it for it to bog. Throttle response is so good now, that I don't see a need for that anyway.

Tag 1 1/8" risers/adaptors with Protapers and Cycra handguards really cleaned up the cockpit. I re-routed all wires, attached brighter front turn signals to the headlight shroud, and checked all wiring connections.

Pics coming.

Who wants to go explore?:)

I'll go exploring with you. I just had my suspension done on the yz250 and want to go try it out (whoops, hills, rocks, etc...)

We both can get acquainted with our "new" (to us) bikes.

btw... I know how clean your X looks and I will be jealous of your cleaned wr450 cockpit. My wr450 looks like hell since I began racing it two years ago. I really need to reset it back to a normal appearance and start all over again.

Hmmm... there's nothing close to my house for this. I always have to trailer it somewhere.

Next time then...

Yes, I did the thick o-ring. It made my X sketchy as hell on hills, but it works great on the WR. The bog that is left could be tuned out with some messing with the AP duration and timing, and I will get to it some day. For now it runs good enough. It only bogs when I check to see if it bogs, not when I am just riding.

So, what is up with all the vibration? My hands go numb in 40 miles!

I'm running left overs for now. The left and right don't even match :)
I suppose off road the vibration will be less noticable, as I will not be in constant throttle mode. I rode the horse trails near my house for about 25 miles last weekend, before I did this first phase of the re-do. I can't wait to ride dirt with a non-stumbling, straight-barred, all-greased-up mount....

Next is the swingarm greasing, stiffer rear spring install, rub strip, and chain/sprocket change. I might need to re-valve the rear, as I am OUT of compression adjustment; it is all the way firm.......................................
