I bought myself & Girlfriend a Matching pair of the 96 XP's and I finally got hers running like a Champ! Now, Mine went Crazy at the Lake over the Long Week-End! It Starts fine and Idles Fine and runs fine, Some Times, Then, I would try to give it gas, all it would do would Bog Down and I noticed when I would hit the VTS trim button up ~N~ Down, it would try to take off... After a couple of few minutes of doing this, it would run great for 5-10 minutes only to start doing the same thing all over again!!! I unhooked the VTS and it never would run right so, I plugged it back up and, I would have to Hit the buttons up ~N~ Down all over again to get it to take off.... Anyone ever experience anything like this? Like to drove me nuts! Any help would be appreciated...... Thanks...:confused:
 
Do you still have gray fuel lines?


If you do... replace them, and clean the carbs, fuel select valve, and the filter.

DO NOT CONTINUE TO RUN IT! A 2-stroke engine is lubed by a small amount of oil... and it's transported into the engine via the fuel. If it's bogging... you aren't getting oil into the engine, and you can seize it.

I pre-mix my Oil at 40-1 Ratio Using the Bombardier Synthetic.... That's why I'm thinking something is shorting out cuz when I push the Trim Button a few times it seems to straighten up for a few minutes only to do the same thing all over again.......:confused: It's really weird..... Thanks for your input though.....
 
check all your grounds. I think we all know water and electrical dont exactly get along lol. Pull the cover off the VTS box and see if its filled with water. Seems to be a pretty common issue with those. Hope i shoot ya in the right direction and good luck!
 
I took the VTS box apart last Night and to my surprise, it was pretty much Dry! Just had a very little Moisture in the bottom but not even a puddle....
I'm thinking I may have a short in the VTS Switch cuz when I took the VTS box apart, I was thinking water was going to come running out but, the Unit looked nice ~N~ Dry....... Thanks for the input! :bigear:
 
I realize this is an older post but I have this same problem and about drove me crazy. So I thought I would let ya know what I found. 96 xp would crank & rev good for first few seconds then would bogg & sound like it was hitting rev limiter. You could hit the VTS up or down & would rev making me think something in the VTS was shorted. Long story short I had high voltage. By making the trim motor run and pull the voltage down a little would make it clear up briefly. Hoping new rectifier/regulator will fix it.

Very good troubleshooting...I was reading this thinking how the heck would the VTS screw with it...it has to be the carbs. Well I think you make a very valid point.

You can easily test a rectifier by putting a volt meter on the battery and reving it up...if you see the voltage jump to 15-16 volts, you need a rectifier.
