Why do Yamahas come so plugged up? No other mfg does.

Just wondering why Yamaha cant sell a bike ready to ride. The new 450X dosent come all choked up and I dont think anybody elses do either.

yes, the 450x does come plugged. just not as much.

i say its a good thing all bikes come plugged, keeps dump people from going to fast :)

crf230, crf250x, 450x, drz, wr250/450, they all come plugged up .......

Well, at least I have full throttle range on my 250X & 450X :):D

It is only a matter of removing a screw to open it full throttle. I guess that may be a little complicated for some people.

I like your thinking Simon!

I think it has something to do with those silly green stickers.

Its a bit of work and a few bucks but its worth the effort.

not to complicated...just asking why? :)

They come so plugged up to pass emissions so that the bike's friendly to our environment. Yamaha has a unique 5 valve head design that might take some extra "plugging" up to pass the standards... Most late model, high performance four stroke bikes come with smog pumps and lean jetting just to pass...

Yes my X has a smog pump and was lean....but WRs have had that throttle stop since 2000??? right?? why. they were concidered Red sticker back then

No smog pump..

Then why the throttle stop if they were Red Sticker?

To pass noise standards.

To pass noise standards.

Back in 2000??? I dont think there were any?

there is no justification for it in this country. maybe yamaha is trying to pass noise standards somewhere else. note that ktm and husaberg seem to be able to sell a bike that will run, and is reasonably quiet, and has no air-pump b.s. and they were among the first ones to have green sticker bikes that weren't toys.

The WR's stock throttle stop was designed to help it pass noise regs, not emissions.

Sorry to burst your bubble. I have over 150HRS and 10 H/S and Enduros on my 250X and the only time I had to shim them was when i put a Hotcam in it....my valves havent moved at all

I am just kiddin....I knew that would get you a bit bothered. I thought better of sending that...but hell what fun would that be. I know that some honda's have had issues glad to hear that you are not one of them. I have buddies that have the CRF450R and I have had the chance to ride it. Sweet rigs for sure. No hard feelings but since you are on the Blue fourm had to give a red rider a bit if grief..... someone had to do it. :)

No worries Bud!! :):D

450xs get the smog pump INSIDE the engine so you can't remove it easily. :D I'd much rather have more stuff to remove but actually be able to. :):D:)
