The res. locater doesn't do much cosmetically except move the res. to a safer location that is inside of your frame a bit. I wouldn't mind seeing the kickstart cut either. I believe Woody_YFZ has the res. locater kit, but not sure if he's installed it or not.

i cant find anything with a full view photo in it. if ya do a search you may find something though. i almost forgot to mention, welcome to the site, i hope ya come back often. enjoy your stay. we do our best to make everyone feel at home here on ATM.

something i found incase ya didnt know:

Retarding the exhaust cam timing

You'll want to retard the exhaust cam timing if you want to move your powerband a little more toward the top end. If you elect to switch to a kick starter, this mod is a must do. The cam timing cannot be left stock if you want to kick start it.
This mod simply moves the power a little more toward the mid-to-top end and away from the bottom-to-mid end. This is basically a personal preference, unless you elect to bolt on a kick start system, then it's mandatory. If you like your power a little more on top, it's safe to move the exhaust cam one tooth from top dead center.

To retard the timing on the exhaust cam first find top dead center (refer to shop manual), relieve the pressure from the cam chain tensioner, pick up enough slack in the cam chain in order to move the exhaust cam one tooth on the chain in a clockwise direction. Know that the intake cam will have to be moved in order to create enough slack to move the exhaust cam. In this diagram, at top dead center, you'll notice that on the left (stock) there are 14 chain link pins from the white dots that we painted on the chain. On the right, after we moved the exhaust cam, at top dead center, there are only 13 cam chain link pins from white dot to dot. As you can see, we're actually retarding the timing by one tooth. This lets the motor rev a little more on mid-to-top end of the powerband. When adjustment is complete make sure the horizontal timing dot on the intake gear is visible and horizontal with the gasket surface on the cylinder head.

Follow these instructions for the cammod -> [Only registered and activated users can see links. ]. Hardest part is getting enough slack to actually move the cam. Only took me about 20 minutes to complete following those instructions though .... DON'T FORGET THE LUBE!

How much are you paying for the kickstart kit? I'd love to get it, but don't want to be paying $350+ for it my self.

shaneyfz450;
As was mentioned, welcome to ATM. It is good to have another ATV enthusiast on board!
Hopefully you will find this place helpful and friendly.

Thanks for giving him a hand guys.

Here is a link to a ton of good info from some good folk (the Dogriders) who spent a lot of time modifying, and recording/writing down the results. Feel free to check it out!

I tried installing it and it won't work because the bracket to hold the plastic wasn't even close to the hole in the plastic. I worked on it for about 2 hours trying to get it to work and finally took it all back off and left it in the stock format. So anyone interested in a reservoir relocater kit? $25 plus shipping. It also has a cover for the master cylinder.
