Gotcha. I don't live too far from you. I'm 15 min south of Richmond. We plan to go up to LKA a few times this summer to check it out. I have been by it several several times but never been out on it but we plan to change that this summer. We were planning on staying at the state park. Any campground recommendations?
 
I think the park would be my 1st choice, then there's Christopher Run, Duke's Creek and Rocky Branch not sure which of those are preferred b/c honestly it's been a long time since I've checked them out and things change.
 
We will prob take a day trip up in the spring to check them out. We have always had good experiences at state parks.
 
This wear ring should be ok to use right?



Rebuilt pump, new fluid, and wear ring last night. Ready to water test now before I put time and energy into the cosmetics of it. But with the high of 35 degrees today I think the test ride will be put off for a bit

So I got the starter rebuilt finally. Bolted back on tonight. Dropped a good battery in it and hit the start button. Motor would turn over great. After trying for several minutes to start it and nothing, noticed a rookie mistake. So I turned the fuel to the on position and tried again. Choked it and it fired right up. Bogged for a good bit but then cleared all the oil out. She has nice snappy throttle response. But it was late so couldn't really run it. Can't wait till the 6" of snow in the drive way melts so I can roll it out and put it on the hose for a minute or two. And maybe if it gets above freezing here take it for a quick test spin. If all goes well then on to the cosmetics

Temps pushing 70 on Wednesday :). Water temps still too cold for my bones.
 
Lol. I hear ya. Don't plan on getting wet. I'm always a little nervouse on the old 2 seaters getting tipsy. 3 seaters not worried about. Just anxious to make sure she runs ok so I can get started on cleaning it up and ordering seat cover and some hand grips etc. where is a good place to get hand grips for the skis?
 
Well it was nice this weekend and finally had a chance to go for a test run. Bad news is I think I need to adjust the carb LS screw. (Bogs bad when hitting throttle from idle) but if I feather it she will then take off like a scalded dog! So am I on the right track thinking I need to turn in the LS screws?
 
If pulling the choke during the bog helps then you are lean on the low side and need to turn the LS needles out to allow more fuel in.
 
Sorry, forgot to mention I did try to pull choke out while it was bogging. Soon as I pull it out she dies almost immediately. That is why I am thinking the LS needs to be turned in an 1/8-1/4 turn?

LS screw is for idle only. Do not use it to correct a low speed hesitation. You need to check pop off and make sure your jets are the correct size and carbs are absolutely clean.

It's more of a bog than a hesitation. Carbs are clean. Jets are clean and I believe are the ones from the factory. If I'm having this bog as soon as I come off idle, would I need to raise pop off pressure? Also, would a restricted flame arrestor cause this issue? It was all out of shape but still together.
 
Yes a filter that is too restrictive could cause a rich condition but being a little bent up should be OK. Yes you can raise pop off to remedy a low speed hesitation but start with plan A and turn the LS needles in a bit. There is a lot of range there. Just never turn them out over 2.5 turns.

^this.

If it's loaded up off idle everytime then your pop off is probably wrong. Only extended idling should cause it to load up with the wrong LS Adjustment unless they are WAYYY off
 
i set the LS screws to what the manual said. If I remember correctly when I rebuilt them, the pop off was on the high end of the specs. (I always check pop off before and after) when going back together it was on the low end but still within specs so I figured it would be ok. The ski does seem to idle pretty well. But soon as I hit it even slowly she bogs unless I keep pumping the throttle till she takes off like a bat outta h*ll.

Finally had a chance to mess with it tonight. Pulled the carbs off. LS jets were at 1 1/4 so I left them. Checked the pop off pressures and they were both at 16!!! I know I didn't set them that low. But I guess it is what it is. Changed out some springs a few times and got the pop off set at 30 now. I'll let you know soon as I can test it again.
 
So I took it out today. Much better but something is still not right. Before it took ALOT of feathering the throttle to get it to go. Not you just have to pump/feather it 2-3 times and she goes. Seems 1/3 throttle wants to try to start to bog. Pulled carbs off and double checked PPP offs again. They were about 33-34. While I had them off set the LS screw at 1 1/8. Took back out and same thing. Any thoughts???
 
Sounds like the 3 transition ports in the carbs might be plugged. Mine xp did the same thing, I thoroughly cleaned these out and had a strong stream shooting from each hole and it ran great



96 XP800!
Keep the 2 strokes alive!
 
I did try to slightly pull the choke out when it was bogging. Just killed it. With all this info and the pop off raised and helped the issue does it sound like starving for fuel or too much?
 
So I have read a few different things on the net. What are the pop offs supposed to be set at for this motor???
 
Ok.....update...I pulled the carbs back off, made sure everything was clean and clear, holds pressure, pop off set at 23 per manual. L/S screws 1-1/2 out. Checked fuel filters in carbs. Checked filter under hood. Went for a ride and it was a bit better. But I would have to pump throttle 2-3 times then it would take off. Ran great as long as I was going and didn't let all the way off throttle. At WOT it almost sounded like it was hitting a rev limiter. Back on trailer, adjusted LS screw to 2 out. Back in water. Got a hair better. Now you can hold wot from idle and it will bogg got a few sec then take off. I was playing around with the choke. If I pull the choke out 1/4 way and twist it to get it to stay in position. It's fixed! Lol. Runs great off the hole shot and at wot it doesn't sound like it bounces off a rev limiter.......ssoooooo, what next? It has 1.2 N/S in it per manual and what was in it before. I have no idea what jets are in it. So what should I do?.
 
Was talking to some people today about this.....based on. The info in the above post should I lower the pop off a few psi or try 1.5 or 2.0 N/S? This thing is driving me nuts!
