Lets hear about your Modded Hawk

I think I need to restrict some flow as max h20 temp is only around 150..QUOTE]

running water temp should be under 150,absolutly not over 150.you will shorten your engines life drastically if over 150 regulary....

You'll have to explain that one to me?? why is it that I want all my other motors that are water cooled at 180?? Ive never seen a thermostat below 165??
 
your thermostat should open at around 115 ,I dont know the why's and how's of temps on sleds but know the rules,your correct for bikes...cutler performance center has a good write up on temps for sleds they might mention why,moded or not same range applies.I know in my bike manuals vs sled manuals will both mention different opening temps to check for on the thermostat..120-140 is what I try for for operating temp....changeing thermostat somwhat regularly is inexpensive and helps to eliminate one of the factors that can shorten engine life...
 
RIP Twoskis!

I cant put into words that I can type how happy I am with my mod..
The machine feels and handles much like a bike and FAR better than origanal..ergos are fantastic.. chewed up a few new 800 xps coming down the mountain:D:D
Its going to be a great season!!

It was never just the machine nor the engine, it's the concept of the one ski snowmobile. In the right hands this design is going to turn the industry on its head. If the Twoski reader snickers at this show yourself at Hawk Fest and experience a whole new world.
 
Darryl my vapor reads like 115degrees when riding in good snow conditions. I have my temp sensor mounted in the thermostat housing. hope this helps

Thanks les.. I was getting a reading of 115 and an avg of about 125..with a high of 147 the other machines with us where boiling over or the light was coming on..
My cooling system seams to be working better than stock..we where riding a wet concrete like snow road for about 15 miles during the high reading..
water boils at the same temp whether its in a car or on a bike.. I would think the lower thermost on the sleds may help keep the temps lower..
a motor needs a certain base temp to run well, all my past exp, says thats higher than 150?? but it runs great and hauls the bacon..Now I just need to learn to ride it...
 
Ready for the silencer

Just started it yesterday night and tonight again without the silencer just to make sure everything works right, 14" track spins no prob, suspension feels good without any revalve. That Gen 2 Jaws is surprisignly quiet without the silencer by the way. She has been a real ***** to fit in the wider frame, looks good now though. She's getting the custom silencer treatment tomorrow then she'll be all good to hit the slopes.

Sometime this week I'll be going for a first test ride.

Let me tell ya boys, this is one ***** *** track right there ! It's been way too much work but I'm happy with the results so far.

By the way, Loctite SuperGlue Extra Gel is the best damn thing I've ever used to glue grips on. I glued the Dual compound Renthal Grips I got there with this glue and within 5 minutes, they were just like concrete, hardest assembly I ever achieved. Seem like I'll have to cut them to get them off which is perfect !!!

Thats looking good TLk!!! how about showing us a photo of that suspension??
 
Here's a shot of her 14" wide arze ! Of course it would be nice to have a 12.5 or a 13 incher right beside to see the difference but this photo will come eventually.

Took her out for the first time yesterday in about 2" of base and 1" of pow just to see if everything worked good. Indeed, everything worked as expected, the real test will be in 36" of fresh Revy pow going up against a 162 M8 or Summit ! The extra inch didn't seem to give me trouble steering or leaning at all.

Sorry no suspension pics for now... Oh and this part of the project worked grrrreat too !

what did you do about the belly to fit the widened skeleton?

What people have to understand is that this mod is about throwing away (or in a box!) most parts on the Hawk except the 2 main frameplates and fork assembly. So all the hooks out there have had to be properly redesigned, spaced/shimmed/bolted to fit the + or - 1/2" they needed in order to still fit the stock body panels hook system. The rest 1" longer like jackshaft, driveshaft, motor plate, all the cross bars... It is a major mod, complete dissasemby of everything is required. Sounds kinda simple to add one inch but how the hell did ran into a lot of problems to solve with this projects... Now everything seem to work great and I'm super hapy about it !

It was very important to me that the mod allowed me to run the stock bodyparts ... And I don't exactly know why, it would have been way easier to just not run the back cowling for example... I don't know maybe it's because I want people (sledders mainly) to relate this particular machine not to a true one-off mod sled (even though it kinda is) but as something out there that had potential but has never been taken to where it should have been for XYZ reasons. Kind of a tribute & ultimate respect to the potential of the machine to do it that way I guess...
 
13"x 144" VS 14"x 150"

How can I say that to sound right... "Unfair" probably. Well, you guys can judge by yourself. A 12.5" by 136" looks kinda funny beside it.

Full report to come... first results from the 2 days of riding I got on it is that it's just something else right there, another breed of bird, not sure how to call it still...

By the way Lox has my black plastics/graphics not to confuse anyone !

Funny thing is Lox's machine and mine are "grown-up twin bro" !
They're 1 digit difference on the serial number ! He has #18 of '08, I got #19 !!! Both came the same from the factory as 144" "MTN" machines.
