Thank you. Probably will use a combination of silicone reducers and tight radius aluminum elbows.

My goal is to keep ski as OEM looking as possible. I considered an inline resonator with water injection mounted in the left gunnell but want to use the original SJ components. I can always go that route if my design doesnt work.

The clearance under the manifold is even less. The starter and cooling intake get in the way. I will use tight radius aluminum elbows and silicone reducers to make a clean strong transition. Running parallel to outside of manifold gives me 4 inches of clearance.

I guess I should have waited for final assembly to trim the elbow. Lol. I have Gp1200 tubing I can use to extend the elbow. Ill give that a shot. Thanks

Not happy with the exhaust transition.

Stock exhaust pounded out and 2.5 inch holesaw for tunneling new channel 4 inches below OEM location.

Cut (2) 2.5 inch air vents for the demands of 1200 ccs. Holes will be covered with flow rite vents and modified dash. Lowered the exhaust tube angle to allow it to run along the bottom of the engine compartment. This gave me the room necessary to clear the carbs. Now I can run the reed cage...

Looking good.

Professional craftsmanship by Robin Haas. From 160mm to 115mm. Need to have him cut another 15mm.

I had good results trimming the 4.5 inch opening to created a tighter radius turn . That allowed a clean install with no Interference from the bedplate, manifold or hull. I will post pics of the finished elbow.

Yes. I find both sites have a wealth of knowledge. Just trying to share. Did you get the FX140 elbow yet?

Vumad - Thanks for the link. Madmat - Anytime. Might have both skis in Daytona.

I can't take credit for the forward mount with gflex epoxy. I copied that idea from another ski. That crap is strong. The mid shaft is OEM SJ that's cut back and rethreaded to 115mm by Robin Haas. The waterbox will remain OEM SJ. The exhaust needed to be moved slightly on the carb side...

It allows me the ability to move the motor rear to meet the shorter mid shaft. Creating room forward for the extra cylinder, fuel tank, water box and battery box.

Im squeezing a 1200 triple into my 2002 SJ. I started this build about 4 weeks ago and have been updating build on pwctoday. My build goal is to have a OEM looking SJ when Im finished. Im going to post all the pictures up to this point. And then start with a day by day progress report...

i just installed a Riva spring in my RN. I didnt keep the directions but I definately remember a reference to cutting a portion of the spring when used in an aftermarket mount. And BTW the spring was crooked on my stock setup until I smacked the bolt with a hammer. try suspending the handle...
