Custom 340 Snojet Astro
The original 340 fan cooled Astro was designed as a trail sled. I selected it to meet racing rules for VOLS racing in Minnesota. It met the class requirements of 'older than 1985-fan cooled engine-under 400ccs'. It was extremely light at something like 330 lbs and was/is probably the lightest sled available for that class.
I blew a total wad on it and discovered in its first race (as we were lapped quickly) that you can't build a nice stock sled and expect to win. My competitors were really dialed in on clutching etc. or they were cheating like mad. I never went back and sold the sled at a huge loss (what's new.) Here is what I did to it.
Chassis
Polished the aluminum. Added giant non-boot grabbing aluminum foot stirrups. I had stainless steel spreaders made. And we deleted the ski shocks as they were not needed for oval racing.
Suspension/track
New track with hard-to-find old style short pick studs were used for traction without being so long they would destroy the tunnel. The suspension was thoroughly rebuilt. I used the best new bearings, new slide material, cleaned and painted aluminum pieces. Small idler wheels were added to compensate for low snow conditions and to take pressure off the slides.
Gas tank
My business is making fiberglass tanks and fenders for motorcycles so making a custom tank to replace the broken plastic tank was not all that difficult although it took a ton of time. I had the top covered in carbon fiber and the sides were painted to match the seat. It was coated on the inside to withstand the leeching effects of ethanol. A quick-read site gauge was added for racing. (The team AARP sticker is a tongue-in-cheek adornment as my racing brother and I are old.)
Seat
I custom made the entire seat; wood, foam and trick custom cover.
Dashboard
I made a carbon fiber dash board to match the tank and added graphics to give it and the sled a professional look.
Customized hood
The stock hood had some great lines but was hidden buy an ugly windshield and a protruding headlight. I did extensive glass work to mask the old hood. I made a super low black windshield and painted a three-color scheme.
Handlebars
Since I am a motorcycle guy I used a twist grip and motorcycle style brake lever on broomstick bars. I have used twist grips on all my snowmobiles to and never had one problem with them.
Engine
Engine was professionally built to my specs. Porting and all internals were bone stock to comply with the rules. The engine's exterior is coated in Swain's BBE-a black body emitter which draws heat out of the engine. I used the stock exhaust chamber. The engine was painted so the under hood looked as good as the exterior.
