Everything was replaced, updated, modified etc over the years.

Here is a video that brings us up to 2006:



Well the ESR330R motor was a good motor for what it was, it was time for a bottom end rebuild and that set the wheels in motion to build a motor I have wanted for years. I also found out that I had cracked my -1 Westcoast swingarm. While it made the bike a ton of fun to ride, it ultimately hurt me in a lot of races so it had to go.

So I pulled the motor and shipped it off for a rebuild. I rebuilt every part of the bottom end. All new transmission with Yukon gears, shift forks, an 8 plate clutch mod, all new bearings, new clutch upgrade kit, clutch pivot arm, billet basket, clutch hub, crank....everything except the main and counter shafts and the gears that connect the crank to the clutch basket. I sent the motor to FTZ Racing as they I have had good experience with them in the past. I will also be rolling out my old FTZ 250 motor in my 85 R this year, but that is another story.

I then started accumulating parts for my next buildout:

A Lectron 48HV from Packard Enterprises.....Dennis is a great guy and super helpful.

A Westcoast +2 with double coating of powder. FYI, if you use a glossy white powder, it is runny when baking and ultimately does not cover well. Look at my -1 Westcoast above. The powdercoater has agreed to repowder that swingarm again for free since that was only done a few years ago and should not have pealed so bad.

Well, once I started getting parts back in I realized that to acheive what I wanted to do, I would have to make some modifications to get it all to fit. The carb bowl is a 200% capacity bowl, but would not clear the kick starter gear so I had to modify the bowl to fit.

I also had to modify the frame to fit this monsterous carburator:

I then got the pipe in from Nick "NOS_350X"

I sent that out to be ceramic coated:

Next was the intake: I need to run an airbox when we ice race due to all of the snow and water flying around so I had to custom build a box. I built the box so it could be separated from the intake boot. That way, I can choose to run the box or just an aircleaner.

I also modified the case to fit a 16 tooth front sprocket.
