Has anyone droped a tooth on the front sproket. My wife doenst care about top speed so we think it might give her some more power around the dunes

 

Did it on my raptor, made a world of difference and only lost 1 mph on top end. Go with it, but make sure you get a quality sprocket.

 

My friend did it on his Z400....he went with the 13 tooth and honestly you cant feel anything different....and I have not had a chance to drag race him to see if it did anything...but as for noticing anything different its not there.

What kind of Quad? It made a very noticeable difference on my lt250. I went up a tooth a few months ago. Since then, I rejetted, added a FMF silencer and replaced a weak coil. After that, it pulled as hard with the 13 tooth as it did before with a 12 tooth. A week or so ago I put the 12 back on and can really feel the difference now.

 

Sorry about that,it is a 2003 z400. I did drop a tooth on my raptor and it made a difference so i hope it would do the same on the z.

 

I would think that due to the wider power band, changing 1 tooth wouldn’t make as big of a difference on a 4 stroke. Front sprockets are cheap and easy to change so I would buy a -1 tooth and a -2 tooth and try them both.
