Grey Wire Mod On '05 WR

[Seabass]

I just picked up my new '05 WR and the mechanic said NOT to cut the grey wire, but do cut the throttle stop. Is this guy high?

Looks like it is still a valid mod in 05

Why is it that no matter where you go Yamaha dealers dont know f#ck all of nothing!

Luke...

You are soooo right. ?

As official factory representatives with tons of resourses at their disposal, it never ceases to amaze me at how screwed up so many dealers are. ?

Thank goodness for ThumperTalk. ?

I just left my local dealer and he looked at me like I didn't know what I was talking about when I mentioned the grey wire mod.......... ?

I rode my 05 wr450 yesterday for the first time since I cut the gray wire and the throttle stop, it makes a big difference, now it runs like it should.

I pulled mine. Runs better. Took the advice of others and pushed it out of the connector (6 wire on '05) instead of cutting. Thought about taking a picture for the "didn't-have-a-clue" dealer but decided ...naaah, f'em.

However, if you do the t-stop and gray wire along with exahust baffle removal, be prepared for hard throttle backfire (at least at my elevation/temp - 500ft/85 deg). Thinking of re-installing snorkle until I can get ahold of the "JD" jet kit ..............sounds much better with snorkle out.

ENJOY the bike !!!

I can't understand it either, surely they can create some kind of knowledge sharing database. Unorganized dirtbikers are doing it all over the world.

Texas I highly recommend the JD kit but if you think your getting a lean backfire when your winding it on hard you can adjust the standard needle up a clip (put the circlip down one notch) rather than putting the snorkle back in.

Lukes right and a richer pilot jet will also help. ?

[Texas4play]

Yeah, it's definitely lean. I've also wondered the possibility of just tweaking the fuel mix screw out richer some. Did anyone experiment this step before going into carb.?? Results?? I know I'll do the JD kit but I'm just curious.

The JD kit is obviously a good thing, but based on my experience the zip-ty is all I needed to get my bike going 'right'. I took the snorkle out, did the air box mod, throttle stop, etc...all I had to do was install the zip-ty and all off throttle back fire stopped. I think some people get a little carried away and don't take baby steps when doing this work themselves. Just my opinion... ?

Ditto, think I'll give that a try.
