Is this something that is on the TE610's as well?

 

[HuskyDude]

I do not believe the 610s have a throttle stop installed.

Some one will read this and confirm it. But I'm pretty sure you're OK.

 

[CrankN]

Yeah nothing on the 610's.

So the 'stop' prevents u from opening the throttle to redline? Is that its purpose?

 

[HuskyDude]

Well yes...But I also believe it has to do with getting the bikes into North America or better yet California. Something to do with emission controls.
Also the emissions canister, O2 sensor etc.
Maybe someone else will chime in and agree.

Emissions & noise are measured in relation to the top power made by the bike. With a throttle stop they get measured at a lower throttle position where there is less of both.

Is there a throttle stop on a 07 TE450?

Yes!

There were 2 models in 2007, since you are in California you almost are certainly asking about the non-Euro bikes which had the throttle stop in the top of the carb.

For more information for that bike and the 2006 bikes:

I actually got my bike a few days ago, shipped from Oregon. Not a 100% sure, but I think from what i've read on another forum that I have the Euro3 version? It came w/ a radiator fan, does that sound about right? If that doesn't, I will definitely do this mod.

You may have the Euro spec version. I think there are only 2 types of throttle stops but am not sure. There were few 2007 Euro bikes in NA compared to the non-Euro.

If it has the throttle stop then the throttle will only turn 1/8 turn as opposed to the standard 1/4 like normal bikes. If you do have a 2007 Euro bike then be sure to specify that when asking questions cause they had a few things different about them. There is knowledge on CH regarding those bikes i.e. "wetdog" had one.

So, my throttle turns more than 1/4. Are there other ways to know for sure that it's a euro version?

Well that means there is no throttle stop.

I would start up a new thread asking "do I have a 2007 Euro bike?" because the people that know those things are probably ignoring this thread.

That's a great idea! Thanks!

Great info--thanks for the pictures ioneater.

And fwiw, my '08 TE450 did NOT have the stop installed. (Wishful thinking I suppose that more power would magically appear in that manner...)
