Glad you enjoyed it

Awesome. I did not know that.

Thanks, will do!

Thanks 👍

Glad you enjoy it!

Appreciate it!

Thanks for the info

You bet!

We've been working on this thing so long I don't even remember anymore. That was 6 months ago. I guess we should finish it up soon.

It was there when Brad bought the sled. I don't have any details on it. Sorry.

Awesome! Thank you!

We think they "fixed it" after the detonation. Meaning they just threw a new piston in and ignored everything else. The more we dig into this thing the worse it gets.

Do you know what RPM they should run?

Pipes and follow the pipe manufacturers jetting and clutching.

@@nuttersspeedshop Any brand you would recommend, next is trying to find said pipes for that old of a sled.

I don't know if anybody still makes new pipes for 20+ year old sleds any more so it will probably be whatever you can find used. I'm not going to recommend a specific brand. I think they all work. You can search for dyno comparisons and maybe find some info there. I know when I was trying to figure out what my 650 pipes were I found a ton of info with internet searches.

And some water too.

Thanks! I will check this and clutch for the pipes!

It isn’t circumference, it’s length of barrel. The longer barrel ran around 8k rpm’s and made 30hp plus over the single. The short straight barrels ran 86-8700rpm for 43hp with slip needles, a timing adjustment and new 2.5, if I remember right slides for the carbs along with P-8 nozzles/ needle jets. If they where like PSI mod blasters, the Hi-RPM pipe also resonated about 9600 rpm and worked well there. I think pSI used Q-0 nozzles with a PSI needle. Supposedly similar to a 97 Ultra SPX needle. Or 1993 storm needle. And 11 degrees of timing versus 12 degrees of timing for the SLP HI-RPM pipe. I know this is long since figured out for this sled. It’s out there for others that may try and pipe an ultra in the future for a vintage muscle sled. I enjoyed many seasons on an Art Sever/Engine Tech ultra 800, with PSI mod blasters. Tried SLP hi-rpm on the sled stock and with the big bore. The PSI just ran more consistent. One of the few thing Bruce at Pretty Shitty Investment did right in the late 90s..

But how do you know it's really a good engine without tearing it down? This one was running and we never expected to find problems like that rod.

@@nuttersspeedshop thats true but at least you could compression check it? I guess i was looking at the overall monetary aspect. If he has the coin to drop on it then it looks like a crank rebuild plus at this point?

We do that on purpose with flooded motors sometimes. Pull the plugs and put a torch at the plug hole and pull it over to burn off some of the excess fuel. It just goes poof. Not even loud. It probably falls into the category of 'don't try this at home.' but we lived.
