How the heck do you get the chamber into the coupler on the headpipe?
I am trying to put a Mod pipe into a SN.
They fit together out of the ski, but I cannot get the chamber
into the headpipe once in the ski
What is the trick, besides soapy water, busted knuckles and hours or yelling, cause I have already tried those!
 
how i do it:
1. attach attach rubber coupler to head pipe and clamp- put head pipe to manifold
2. dont need to do but is easier remove gas tank and lossen water box
3. Twist and push chamber into the coupler aided by soapy water then pull water box onto end of chamber
4. clamp and beer time

dont bolt the head pipe to the manifold

slide the mod chamber in, if its like mine it has to go to the right front down by the water box to get it in, the manouvere it back over to where its supposed to be

put the front of the mod chamber into the water box tube

now locate the rear of the chamber into the coupler on the head pipe

bolt down the head pipe

now you can do the coupler clamps up

wd40 helps

ive found if you bolt down the head pipe first it will never fit

this is all without the gas tank in
 
you need to carefully get a screwdriver up under the coupler and start working it around....make sure the hull ribs are ground off flush for pipe and chamber...

If you think the mod is hard, you should never get a limited. I use silicone spray. I leave the headpipe unbolted until everything is hooked up. I connect the waterbox end after the coupler end. I take out the gas tank.

I have run into this 1 time and 1 time only- the new coupler I was installing was a 1/2 smaller id than the old one. grease the id of the coupler, slide entire coupler over the end of the chamber and let it set in the sun a few hours, wash all grease off and then install using glass cleaner.

I just put on new couplers too. I NEVER use any lubricant that leaves a slippery residue. Windex, 409 etc dries up clean. I've used wd40 in the past and after some hard riding the exp chamber can and probably will come out of the coupler.

Water box, battery and tray, gas tank out, heat and windex works like a peach. New couplers are tougher than old ones.

Just my .02

X2-NEVER permanantly install using anything greasy-it will NOT hold! My idea of using the grease is ONLY to get the thing to slide over the chamber completly and allow it to stretch out a lil and then clean real well.
