i don't believe we have any of our own pictures... nor do i have any helmet cam video since i couldn't find it before we left... im not totally sure where the track got the idea that i am 29, the sled is 29 years old... im 30.... actually since im sure the sled was probably made in late 83 (84 model...

its pretty short notice but anyone who can should come out and show the track they need to make this a event happen more than once a year... http://www.sharonspeedway.com/events/137/snowmobileatvside-by-side-races/ even if your not racing, come thru the pits and say hi, its all access admission for $5

18-24"? ! that would be a ton of snow here! must be nice, some years i wonder why i even have one of these damn things. We have a dusting this morning, it will melt by noon.

btw chuck isnt going to have a jack shaft like you want... when I a pondered this a couple of years ago I decided the best method would probably be to cut a yamaha jack shaft and a polaris jack shaft basically in half. The yamaha shaft is hollow so as far as I can see you should be able to machine t...

he is busy building lighting machine's and screen printing shirts. also shooting a coyote 40min into deer season and a small doe on the first saturday. http://www.youtube.com/watch?v=ob0oACD-gWA&feature=c4-overview&list=UULSZ_YozKf-iW02yh4NMZEg https://www.facebook.com/pages/Black-Dog-Ink-Sc...

use yamaha head gaskets only... and preferably base gaskets too

the serial number on the water pump housing is really the only way... there are also numbers cast into the bottom of the crankcase but i believe they will only be 8M6 ('81) or 8U9 ('83+)

technically 5hp briggs should be run the same way hahaha

that dude has a ton on info on his site that is really eye opening (porting and such) its just a shame he seems to have dropped off the face of the earth

aqaaaaa 2 stroke pipes hurt my brain... 4 stroke pipes are hard enough haha

i have read some about pulse waves and such.... but i dont have the tools or skill to actually make anything to try... luckily i also dont have any reason to..... yet haha

wow looks like 2 very nice sleds... kinda makes me want to tear down and rebuild my 84... if only i had the time

i believe every word this guy says....

read it...
then run it like you stole it to 3/4 throttle for the first tank of gas... dont start it up until you are ready to rip on it, not even just for a bit...

do you have experience building 2 stroke pipes bob? i have oven wondered if you could "straighten" a pipe out and still have it perform the name as long as the diameter at any given length from the piston was the same? or do the bends also affect the powerband?

i deleted the parts about 10 july, 2013... when i read this before i thought we missed it. i still cant go tho, i have lawnmower testing to do... we have parachutes now haha

actually i just re read your post tony... i thought you were trying to say that all of the jets went in the bowl... what your are trying to tell the OP is: Someone probably took the the jets out of your carbs and never put them back. You most likely need all of the jets, including the ones (power an...

your probably going to have to post some pictures of your carbs so we can see if they are stock or off of something else
