Quick question, my shredmaster plate...

He was making up for the 8 years he was a member and never posted (almost). All those trouble free hours no time to go on the internet :D

Check the ignition box and see what is in there. What are the compression numbers for you on a fresh top end?

Dont think this thread will get much action on here. You may want to try PWCtoday.com there are alot more stand up riders on there that will have experience with that setup.

Down and back is most aggressive up and forward is least. I dont remember how much in between adjustment there is on that brand.

Ask Riva what fuel to use. May be worth checking the fuel requirements of the organization you are racing with.

Suggestion would be to try what you have and see if it dials in, if not then change them. Here is a diagram from Novi that shows the return restrictor



...

Sounds like a good place to start- a little rich. Novis need a restrictor in the return line usually recommend a 95 or 100 main jet in that.

Was the gp a big bore or triple pipe?

Report back when you get into them

Isnt the fuel pump on the carb?

What is in them now?

What is the installed spacing on the couplers? Thinking if they are too far apart it could cause this type of issue. Also how much does the hull weigh?

Yea I thought about it years ago. Was thinking of a vertical plate/bracket between the thru hull and charger with the tensioner and bearing holder incorporated into it. Seemed like would need a...

The guy who built the 15f I have originally ran the turbo setup with stock pistons + 1mm spacer + like 7 lbs boost before he switched to aftermarket pistons.

The shorter rods on the 12f crank...

On 12f rods makes more sense. Originally you said 15f rods and pistons in a 12f motor. They would be way down in the hole.

If you need a 250x rod and piston I have some. Just pay shipping

"I bet a set of high comp forged 250-310 pistons on 15F rods would drop right into a 12F and you would have a pump gas boost ready 12F for about as cost effective as you could get."


15f stroke...

That is setting for Buckshot 50. Your carburetors will need to be tuned to match your conditions. 150 + 115 should be close but you may want to start with bigger jets (160/155 + 120) to be safe. You...

That cylinder block will need to be re-plated or replaced. As for the the re-plating they usually have to do all 4 holes wont do just 1. Not sure if you have anyone over there doing nikasil to call...

Pretty sure the guy in the first 2 posts was running Buckshot 50s

Did you by any chance hook up a garden hose when you attempted to start it? The procedure for the jetskis is to have the motor running before the water is turned on or there is a chance the hose can...

After you do all this work to the 1200 would love to see a video up against a stock 15f.
