    My 86 250R ice racer has evolved again! This time it's a monster!

    Many people on this board have seen my R's posted over the years. I go through the bike every few years to update it, fix broken or worn out parts, try new set ups and pretty much play with my favorite toy. I got this bike as a parts bike in 1997 when I bought my other 1985 R. I built it up from scratch. There are only 6 original parts left on the bike. 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:

    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.

    Damn, every time I see this bike it's more amazing than the last. And every time I think nothing more can be done to it.
    Keep up the great work Chris.

    TORKER.
    THOSE WHO SAY IT CANNOT BE DONE, SHOULD NOT GET IN THE WAY OF THOSE BUSY DOING IT...

    I also had to swap out the HRC Mugen rear suspension for a Works shock because I could not get the larger intake tract to fit with the reservoir.

    I also had to make sure my large carb was getting enough fuel so I invested in a Pingle fuel valve. I also put a pulse port in the cylinder for a fuel pump if I need it. Right now it is capped off.

    Well, the motor was something I could not do myself as I just don't have the tools nor the knowledge to build this motor. I have been through the bottom end of my bikes many times over the past 25 years, but epoxy, case boring, decking, setting port timings are way out of my league. FTZ did a nice job on the motor, so we will see what it can do. Introducing the CP Industries 431 Puma motor.

    I am waiting for files to upload so you can see it all together. Thanks for the kudos! To avoid the tramsmission explosion as much as possible, EVERYTHING in it is new with brand new Yukon gears. I can't wait to get it on the ice.

    Did you run it yesterday????????????????? we would have drove 4 hrs!!!!! lol
    No, I didn't get it out yet. The ice was sketchy there. It is also 4 hours from me too as I am in Maryland. I will be going to our place in GWL next weekend, ice or nor ice.

    Love how u kept this a secret. Even posting about my 370 and how you are just going to run the 250. Hahaha. Got me thinking since my motor is still in pieces that I need to step it up already. Doubt I will make this ice this year anyway. Nice build for sure chris.
