Flame Arrestor

[99seadoogtxltd]

I was doing some carb tuning at the river the other day. I noticed that if the flame arrestor was off, it would run a consistant 6880 rpm. When I put the arrestor back on, the max rpm went down to 6650. Should I leave it alone and let it run max rpm at 6650 or should I make adjustments? Im hitting 57 when the handle bars are turned slightly to the right. Digital says 62 but i watch the speedo constantly and NEVER saw it hit anywhere near the 60 mph mark. Ive never heard of a gtx limited hitting 62. Although I can prove it will do 57!

GTX limited will have a tough time hitting much higher than 57 on the water. Its big ! GSX can pull 62 yes.. but not a GTX.

other's might chime in on the flame arrestor issue .. is it jetted for stock FA ?

Yes everything is stock. The ski only has 78 hours on it now. Its running like a dream. I just replaced all fuel lines, rebuilt carbs, cleaned fuel selector, etc. I accidentally loosened the exhaust and it was he** to get everything back right after that! FINALLY got it though! Now it runs better than ever.
Im just wondering if the flame arrestor is an indication that I need to rejet. Should putting it on lower my rpm? Could I possibly drill holes in the flame arrestor to stop that issue? Just wondering if I should leave it alone and let it go.
I have about come to the conclusion if it isnt broke, dont fix it. with that being said, I said almost!

plug chop! see how the plugs look,ill bet they look fat with the arrestor on.

 

[99seadoogtxltd]

meaning its running rich with arrestor on? so back off hs air/fuel ratio

 

[donkey]

yep, then check the plugs again. but ,its always better to error on the fat side( rich)

Make sure the element is clean. The engine will spit back, and the oil fuel/oil will eventually choke it.
