    Yes I have 2 of those PV1200s and I agree with "Myself" on the need for maintenance. But why in the world did they make it so you can't even get to the the carbs to do the maintenance or...
  2. I have been doing a little more research in this...

    I have been doing a little more research in this rotax design and reliability. Looks like we may have the only 2 or 3 rotax fans chiming in on this thread. And they all are in business of fixing...

    There are a few of these for sale in my neck of the woods. I may get one and put it in my Jonski. Just don't have any experience with a Rotax. Is it sort of a supercharger or something? This...

    Hey Myself. The NADA says this motor puts out 110hp. That's damn good for 782CCs for back in the 90s. How did they get that HP out of it? RPMs? Do you think it they were honest on this HP? You...

    That is what I am thinking "myself". HAHA I crack myself up sometimes!!! Another pun. But is it worth putting money into this old 787? Probably going to need a new crank.

    i am in SE HSV. I am constantly messing with motors as a side hobby. My latest project is a Jonski powered by a 500 yamaha. I am of polish descent and thought the ski at the end was fitting. Got...
  7. I guess you may be replying to me here. If you...

    I guess you may be replying to me here. If you can't turn it with the strap wrench, the piston is hitting something, and there is an internal problem. You should feel a hard stop in this case. ...
  8. Ghebert probably has no compression in his...

    Ghebert probably has no compression in his cylinders now that he has had the head off. I don't think his starter is that bad since it turns it when he is testing his front cylinder - as he said. ...
  9. Hey Oleg! Yes, sometimes his starter bendix does...

    Hey Oleg! Yes, sometimes his starter bendix does not catch. You may have a point that the compression is stopping him from turning it over by hand, and the starter maybe to week to push it through...

    I don't know much about the sea doo motor breakdown of that vintage yet. Yamaha man here. Is does sound like a knock. Anybody know the thickness of the head gasket should be or what the piston...
  11. Hey RipCuda. If you ever get into those carbs,...

    Hey RipCuda. If you ever get into those carbs, look if you see a red dot (square body diaphragm) or light green sort of yellowish (round body diaphragm) those are Mikunis. I got buy with the...
  12. I rebuilt the 3 carbs on a GP1200V with...

    I rebuilt the 3 carbs on a GP1200V with aftermarket, and yes it ran, but I noticed that the hull was getting gas in it - which I believe the aftermarket diaphragm is the culprit here. To bad that...
  13. I have looked at my carb more and I believe I...

    I have looked at my carb more and I believe I have a BN34 that came with a 165g spring and a 1.5 needle and seat. It probably has these high of pressures as you see in the Mikuni manual. There is a...
  14. I agree with Oleg. When you first mentioned you...

    I agree with Oleg. When you first mentioned you got 150psi out of a 96 SP - that is pretty high for this old ski unless someone modified it. (pistons or head). Why the bendix would engage when...
  15. So tonight I did some testing. With my running...

    So tonight I did some testing. With my running ski Mikuni diaphragm and spring, in an old Wr500 SBN carb (92) and I was getting way over 47psi and it still was not "popping". I said what the heck...
  16. Like nmpeter eluded to. When you get the jug...

    Like nmpeter eluded to. When you get the jug off, better check the connecting rod for play. I think your piston is hitting the insert or your pressure tester on your the PTO cylinder. All starters...

    OK ghebert you started this - what did you find out???
  18. Sounds like your bendix is not even kicking in...

    Sounds like your bendix is not even kicking in now. Take out the pressure tester threaded insert you have going into the rear head. Make sure when you have it out that the rear cylinder pumps with...
  19. Understood on the pop off pressure. I will try...

    Understood on the pop off pressure. I will try to adjust to the pop off pressure in the Mikuni manual. There is not much written what the pop off is with the diaphragm installed, but it sounds like...
  20. OK - I just registered and I am going to get in...

    OK - I just registered and I am going to get in on this old aftermarket discussion of Mikuni carb diaphragms. I have been looking at these discussion forums and no body ever gives a why they don't...
