Freestyle Jetmaniac ported 701 - 210PSI - too much for regular pump gas? (PROBLEM SOLVED)

[stefan]

Try a stator coil crank test ther is a thread about it in the tech sektion

Hmm - can you link it?

This might be a silly question but your spark plugs....you are using BR8ES right? Are you using the solid post version (ie, they don't have the removable tip?)

I can't tell you how many times I've switched out those solid post plugs for the regular ones and fixed a very similar problem. Check that, and also change the plugs when you start testing again.

Your jetting specs should be fine now, but the video tells me that is an electrical problem.

I've always bin using the ones with the removable top - tbh I have never seen anyone run the BR8ES with a non removerble top. I've used different sets of plugs, also tried BR7ES. The last electrical problem that I can think of, and that haven't bin changed is the stator coils. Waiting for respond from jetmaniac, and then a new set is up for order!

I only run hard tops, I have try the screw ons come Loose a couple off times. Here is the stator coils crank test http://www.x-h2o.com/threads/37800-Electrical-Ignition-System-trouble-shooting It have help me one time. ATP can revinde your coils too bee better than new cost mee 800 DK turn around time was 7-10 days

Have you check your plug cable ?
Just put some water on it and feel them with your hand if you take the spark don't look else where...

Sorry about not replying on all threads, but many of your suggestions has already bin tried and replied to But keep the suggestions coming. Trying to get a hold of some new stator coils - that's next up for try!

im in the same boat. starving for fuel past half throttle... but only sometimes. gone thru 3 stators, different eboxes, different cdis. im jetted right, brand new fuel line all around, new external filters, cleaned internal filters, cleaned pickups, clean bottom of the tank, fuel selector bypassed, new check valve, tried a different carb. its not electrical. its a fuel delivery issue. the next things to do is check the reeds and reseal the bottom end. if it still doesnt work just build a new motor

 

[Waldbjoern]

Have you seen the YouTube clip - does it sound the same aswell?

Remember to use OEM stator coils new or refurbished from ATP (NOT WSM!)
What kind of fuel line are you running, OEM or transparent type? Sorry to say it Chris, but the transperent fuel line i bought from you was very nice and soft, but 0.5 or 1mm to big, to get it really tight with cable ties. Oem fuel line is the way to go.
If you can and will, we are going to the lake in Esbjerg wensday 10th so there would be extra eyes and ears.

Exactly Matt, thats why im only running Shell V power (octance 99/100) http://en.wikipedia.org/wiki/Octane_rating
Can you get the engine/ski to rev higher, when only opening the throttle 30% or will it still "buzz"
whats the carb settings ?

shell v-power
RON 98.5
MON 86.5
=
PON 93,55.

that actually pretty good. terrible that they started mixing v-power with etanol.

Still waiting to try out the new stator coils. Updates on the matter will be posted here. :bump:

 

[Waldbjoern]

Problem solved!

After getting a new (used stator) things were looking good!

We tried measuring the resistance in the different coils, and found the pulsar coil to be off tolerance!

After trying out with a new one things worked smoothly!

BIG thanks to all who came with ideas to fix the problem, and a special thanks to Chris from ATP for the correct answer to the problem )

--> This is the bad boy who caused the problems!!
