Merry Christmas! So merry we are here instead of spending time with our family's! :p

I believe there is a new years day ride happening there.

Or he could spend the same effort on something that pays significantly more. Problem our sport faces. Luckily people like the guy doing the PJS stuff, torrent, and Waxhead are keeping parts availability alive. :)

I talked to him a while back. He is building high end drag racing parts and put the pwc stuff on the back burner.

That sucks. :(

Start searching and reading everything you can on the forum from impeller/pump tuning, carb tuning, exhaust tuning. Then start a thread with any questions and your ski specs etc.

Great idea!

Looking great!

Check out the zeeltronic ignition. You can adjust the timing to give you that bottom end power you want before it gets on the pipe. @Jr. sells them with customer specific tunes.

WHY?! :eek:

Similar setup with laydown pipe. I run an antigravity battery above the waterline in the back of the hull behind the exhaust manifold.

Looking good!

If real they are a great deal. However, make sure and compare to known real ones or email pictures to ngk to verify. *I ordered acdelco plugs from amazon for my truck that turned out to be counterfit. 30k miles and the plug gap more then doubled...

Line that doghouse with some 1/2-3/4" sound deadener :)

I use both.. But thinking a restrictor is probably enough. (Drill out a seat to 2mm and it fits perfect in the bpipe stinger. )

I have had good luck with a cone spring off mcmaster I think I had to cut it to fit though.. Problem is I ordered a bunch of different springs and balls and dont remember which ones I used. =/ https://www.mcmaster.com/catalog/128/3935 https://www.mcmaster.com/catalog/128/1428

How about some guesses on the next big old thing? Jammers, Jetmates, Chickens; vintage 550 racing seems to be getting more and more popular as well.

Installing my new wax manifold and headpipe, figured I would check my fcv for any debris/sand etc and to my surprise found that the spring inside the fcv had rusted apart and broke in half. So check your springs before spring. :)

I have had good luck with having the uship shipper guys look over the item and send pictures of it then confirming its loaded onto the truck before sending over paypal. Not 100% but better then nothing.
