Saweeet!!

WOW, you got hosed!! Looks like a whole pile of fun stuff to play with!! We just got or pipes for the hurricane project today, I had to go tinker with them.

[Rodneyae]

Would like some opinions on domes. I am thinking about using the sl650 (25.9cc) domes vs the 780 (28.5cc) domes. What dose eveyone think? I know it will raise compression and I will have to use 93 or higher.

Looks like UPS didn't . . . er couldn't play soccer with those boxes! They look intact.

Good luck and keep up posted

Oh yeah, I think the domes will need to be machined to the piston size for clearance.

I dont think a 650 head will bolt on a 780 cylinder, I would have the 780 heads cut.

They will bolt up. But not sure about the squish. Might have to cut them out slightly. Or use ones that I have for a 750 (30.3cc).

WOW, those parts have a lot of miles (UPS miles) on them now. I know many of us will be watching to see if they get any watercraft miles put on them. We love projects Keep us all posted.

[Rodneyae]

Hope to have it running by spring. So we can get some mile on the water. So I will be probly be needing some help. I will be taking a lot of Pics and writing info for anyone else that wants to do the same thing. I am also doing several other mods to it. So there is going to be a push to get this done, because as soon as the warm weather hits I will wanting to hit the water. And I really do not want to ride on the Sea doo.

[ph2ocraft]

Maybe you could post the year and model for the project?

[Rodneyae]

This is going in the "General" 1994 Polaris SL650. I will be adding heaveily ported 780cc cyclinders, triple pipes, pro carbs, not sure if I will use side draft manifolds or down draft, 780 CDI, extended pump, and if time permiting a custom transom exit exhaust.

Day #1

Ok, I did get a few things done this morning, inspite of the 29* temp and the sleet. I removed the fuel tank, floatation foam, and polished a couple peices of the pipe. Not as good as Beerdarts. I am also finding that the filler neck might be a problem, so I will have to modify it or do a custom tank?




I did find a couple of parts for the fuel pickup in the bottom of the tank. Other than that I haven't found any other mystery parts or bounus tools yet.



I also cannot figure out why the stingers have three hose connections on them. Any help would be helpful.

[Rodneyae]

Beerdart, I have seen that. But mine has three pipe cooling ports that connect to the pipe cooling chamber and one for water into the exhaust chamber for a total of four connections. Also the head pipes have two cooling ports each, for a total of 6, the head pipe couplers have no cooling water at all. But the Jugs them selfs have two fittings each, for water lines to run into them. So I am going to have one hell of a plumbing nightmare. Any and all sugustions are welcome.

Thanks,
Rodney
