2008 Superjet Factory B Pipe Problems

[sfadchi]

Ok so I have installed the following on my 2008 Superjet:
Factory B Pipe (with recommended carb jetting)
Caps have been drilled off the carbs and correct settings for high and low
Riva Air Filters
MSD Enhancer
Solas 13/17
Works D Plate
Works Grate

I have installed everything to the specs they provided. The problem is when I take the ski out it's not really fast at all, feels much slower than stock most of the time. On the top end to will feel fast and then start to slow down. The bottom end is also terrible. It I kill it and try to start it up sometimes it will have about 1500-2000 RPM at full throttle. It will not go above that, then after about a minute it pops back to normal. What have I done wrong? Any suggestions would be greatly appreciated.

White wire crossed on MSD enhancer? Not quite dialed in on carbs?

Personally the FP jet specs were not what my motor liked, i ran a 75P 132.5M with a 115 spring. At this setting it was crisp.

did you mess with the adjusters at all or left them the same?

 

[Flat Brapp]

the high low settings..... yes i did. 1&1/4 on the high and 3/4 on the low.

I closed all of the adjusters except the bottom screw. Left it 3/4 turn open like explained in the instructions. I don't see why it sometimes has like a 2000 RPM rev when I'm trying to take off and I feel like im going to be stranded out in the middle of the lake. 60secs later it takes off.

I will check the wireing on the MSD but it was doing this same thing before I put on the enhancer. There is nothing I could have done putting the prop in is there?

60secs later it takes off.

Missed that.

So 1 minute at throttle and it finally rips?

It did that to me 3 times on Sunday when riding. Rode for about an hour. Does not do it every time.

OK talked to factory they have no clue at all what the problem might be. Does anyone know if I should disconnect the factory heat sensor? Could that cause my problem?

 

[SUPERTUNE]

Your heat senor is turning on just after you shut down the engine, so when you restart, the CDI goes into the 2000 rpm limp mode, then after less than a minute water cools the sensor and goes back to the run mode. Just disconnect the pink wire coming out of the cdi and tape it up. This will cure your sensor problems, just always watch your water bypass as a indicator of no water flow.

Thank you so much supertune! That is exactly what is happening! Now I just need to figure out the bad performance problem!
