Boggin prob....maybe.....

[Twin700]

Hey all... I think I got a Bogging problem... but I think I know what it is before I do so.

The bogging only happens in a short time from the beginning.
I mean like when I first start it from a COLD start... I gotta sit all the ski and tap the throttle barely a couple of times to get it up and then it takes off w/o any problems and is fine then.

Then there are times when it boggs when I ride for a long while and kill the motor just to chill and when I start it back up... it starts fine,, but I cannot just punch the trottle and go... Like again.... gotta tap the throttle a couple of times and it is fine after that.

Conclusion.... now I think its b/c the carbs are running too rich..maybe?? and its fouling the plugs... and it needs time to burn off the oil thats on them due to spark?? U think?? Should I run a little leaner on the crabs???

Thanks for comments...

Take a low-speed plug reading and see for sure where you are.

Bryan Glynn .. what do you mean take a low-speed plug reading ??

U mean cruise to craft at a slow speed and see if it boggs?? If thats it.. its fine... its only when I start it back up.. but once it is running.. low speed and top speed response is great... just when starting it up again,, I get the little bogging at first. when I pass the bogging the ski is responsive at all times.

thanks

Here's the direct link to the carb tuning section

does the problem go away when the motor is warmed up? An easy way to tell if its rich or lean, is to hit the chopke real quiock when it's bogging. If it bogs worse,then you are to rich. if it pulls through the bog, then you are too lean.

Bryan, CJ, Wetwolf or Sealion,

Ok.. I went out and rode today on a new set of plugs and rode hard for about 2.5 hrs and took it home and pulled the new plugs out, and took some pictures of what each plug looks like. Now the BOGGing still did not go away,, but only went away after tappin the trottle a couple of times. Now I do notice its blowing smoke out of the exhaust and its WHITE in color. I am thinking since the plugs does not look like it has allot of discoloring... its probably running lean. Can you guys go to my picture site and let me know what you think its running on the plugs due to color??

Hi,, I just took 3 more pics at the end. there higher resolution.... I had to turn on MACRO on my digital camera... since it was less then 3ft away.

thanks for the heads up

[Bryan Glynn]

You cannot test like that - follow the carb tuning instructions exactly.

[Twin700]

Ok,, I will ride on new set of plugs tomorrow when I ride and the lake and drive it for 5min at 20% trottle and will post pics. thanks

[Twin700]

Well,

went out riding on new set of plugs... and it looked the same as the pics shown here at my picture site... any1 know if its running lean or rich by the way it looks????

Also... I did notice that there were some gas spillage on the bottom of the carbs where they sit on the mounting bracket going to the reeds. But I am thinking why there were some gas there is b/c I did take off the flame arrestors and prolly did not tighten them enough when I went rideing today..

well if any1 knows why my POL is boggin.. please post.

here are the pics again:

I'm having a hard time deciphering what I'm seeing in the pictures (probably due to my monitor here) so I can't say for certain what's going on. But I found a pic that Bryan had posted a little ways back and hopefully it may help you read your plugs.

Thanks.. I was just there reading it. It looked like as tomsl750 was kinda having the same probs as I am having. I bet anything.. that I am running a little lean.

I guess I can turn the carbs adjustments clockwise 1/7 (of an turn) and see if the bogg goes away. I think When I purchased my 1st 2000 SLH I had really bad carb probs and even the mechanic at the dealership could not diagnose the prop.. by adjusting the carbs, pop off,, so he gave up and dropped a new set of carbs in my 2000 SLH... which now I have an 1999 SLH and having the same probs as my 2000 slh did.. but my 1999 was not as bad,,, the 2000 I owned... I really could not take off and get pass the start up of the bogg. at least with the 1999 SLH (I own now) once I pass the bogg... its fine,.... untill i kill the motor and start it up again,, and then the bogg is there ,,,, but like I said.. once I pass the bogg and the ski is running.... its fine.

WETWOLF.. I tried the choke thing when the ski motor was warmed up at idel speed and turned the choke on.. the ski just died out... when I kinda accelerated the throttle and turn the choke on... it just died out.. any idea by this diagnostic???

thanks all for your feedback and replies.. your help is really appriciated!!!

Purely a guess, but could the carbs be leaking fuel into engine while at rest?

Applying the choke cuts off air to the engine and allows fuel in. By doing this you are testing for a lean condition (too much air not enough fuel). If the bog disappeared when you did this, you would then adjust the carbs to run richer by turning the screws counter-clockwise.

The one thing that really concerns me is that the threads of the plugs seem to indicate a combustion pressure leak (the black sooty deposits on the threads), and in pictures 6, 7, 8, and 9 the crush gasket does not seem to be as crushed as it should be if the plugs were properly torqued in the head.

If the plugs are not properly torqued into the head, the plug will not transfer heat properly, and you will end up with false readings.

Also a photo or two from the firing end of the plug may be more helpful.
