Better than snowshoes

Man, brings me back.  I used to ice race a ZRT800 triple triple with pods back in the 2000s.  I always tell people that snowmobile acceleration on good panned snow is as fast as, if not a bit faster, than any sportbike I've ever ridden.  It's addictive. 

 

Some of those old zuk triples were real strong. My brother used to have a 700 SRX with a lot of bender ad ons and it was an absolute monster , no trouble making the skis dangle at 65mph from a dig. 
I'm not sure how I didn't kill myself as a teenager. 
Also I totally agree, when it comes to flat out accelerating from a dig I don't even think a liter bike can hold its own against a sled with good traction and clutching.

SAME.  Sometimes I think of all the stupid things I did on trail and the lake and wonder how I actually made it out alive, haha.  I remember being in Aroostook county, Maine, where the trails are pin stright through potato fields as far as one can see, and just going flat WOT for minutes... 110mph in a daisy chain of sledders.  There isn't much like it on earth. 

Today I replaced the first 5 bearings in the skid, the part inside the track, the wheels keep the track straight and reduce friction in key areas.

There are about a dozen of these 6205 bearings in the wheels. Most where trash. 

I'm beginning to think the seller may have been fibbing about when this sled last ran. 
 

Furthermore it's freakishly warm so no sign of snow in the next week. Womp womp. 

With most of the mechanical maintenance done on the big triple I still wasn't super happy with the amount of vibration when running it with the track jacked up. I pulled the secondary clutch and greased the bearings. All felt smooth from bearing to chaincase so tonight I went ahead and pulled the chaincase cover. 

The oil wasn't great looking , so everything got a good clean and it set the tension on the chain and put it all back together. Thinking the vibration may just be from the track that sat in one position for years. Thinking it's probably ready for a test ride once we get some snow. 

I had a little help from a family member over the Christmas break, the lights would only come on dimly on the triple. It turns out this sled has no less than 3 voltage regulators in the system! Sure enough when we unplugged the proper one the lights came on. New voltage regulator is on route. I was really worried I'd be doing two stators in a year for a minute there. 

With a whopping one and a half inches of snow we decided to take the sleds around the yard.

The good news is the rxl wanted to pick the skis up when it comes on the powerband! It needs the clutches serviced and a new belt is on the way. Weekend project I suppose.

Sadly the little 377 was running worse and worse until it would barely drag itself back into the garage. Upon further inspection I found the fuel pump was only pumping fuel to one carb. So off it comes , unsure if I'll rebuild it or order a new one. I'll price both out tomorrow and go from there. 

If the dead cylinder was the one with the pulse line connection, I'd pull the plugs and make sure the crankcase isn't full of fuel on that side. 

I've had the pumps fail with a leak in the diaphragm allowing excess fuel to enter the crankcase through the pulse line until the cylinder floods out. 

In reply to No Time :

That's a good idea, I'll check it out.

Had a rebuild kit in stock at work so I'll throw the pump together on my lunch break and put it back together tonight. Fingers crossed. 

We finally got some snow, enough to play in so I've had the ski doo out for a little fun around the house. Still chasing a high idle but I'm not quite ready to pull the motor to check the new crank seals just yet (yes I know I can do it in the sled with vacuum). 
 

Otherwise I'm sure you could get this thing stuck, but you would really need to try to do it I think. It's a fun little sled but I put it for sale to fund race boat stuff.

Found that the 380 was pulling air through the throttle cable of all things . Got that sorted and a friend who I owe many favours to wanted a sled to take his kids on so off it went to a new home. 
 

Can't be without a project though so let's enter this super rad 92 Indy 440! 
 

Since our winter has been absolutely terrible hardly any snow and it's calling for above freezing temperatures for most of the next week I figured I better wrap the 440 revival up before motivation is gone.

Step one , let's make the little 440cc Fuji motor come back to life. 
 

Step one, remove mouse condo and give the carbs a quick clean. 

Step two, find that the tank is half full of water and many year old gas. Flush the system, install new fuel lines. Put more fresh gas in as the first two gallons was now useless. Eventually I got it going...

Step 3, paint the pipe. Ahhh what have I exposed with my wire wheel? Step 3.5 turn mig welder to stun and play stich up the pipe. 

Needless to say the 440 wasn't taken on trade because it was mint. The chaincase had exploded and used parts needed to be sourced. They arrived last Friday so this past weekend I assembled a new used chaincase in order to make this thing almost mobile. 

Dang it Carl! Filled the chaincase tonight and despite a new seal it leaks profusely. Next step disassemble and coat in permatex ultra black! 

In reply to 1SlowVW :

Leaking from the cover and not the lower bearing I hope!

In reply to adam525i :

New sealed bearing and new seal behind it on the lower shaft. Looks like my cover is no longer flat. Ill disassemble tomorrow once all the oil has let itself out .
