Exciter 570 ( 1989 ) carb set up / jetting ???

[Lasse]

Hi

I need some advice on how to set up the carbs on a Exciter 570 ( 1989 ) for a friends sled.
I have read in many forum that the OEM jetting is a big joke & only BS and sucks big time

What jetting should I be putting in them ?

I'm really lost here.

The sled is 100 % stock and has the Mikuni VM-38 with the heated carbs and so on,
except that the oil injection is deleted and the sled are running pre mixed gas.


Riding height : 250 m <--> 800 m ( 820 feet <--> 2650 feet )


Present carb set up :

* ? PowerJet ? : 200
* Main jet : 350
* Pilot jet : 42,5
* Needle : 6FL68
* Needle jet : 480 P6
* Air screw : 0,5 turn out

.

i have mine 290 main, 1 turn on the air screw. havent messed with the pilot jet or looked at the needle size i went leaner on the clip position one notch. i haven't been able to find much info on the powerjet . just got to play with this sled a few times but i ride in minnesota and i think i will be pretty rich if temp get below 0 ....but i just picked up a psi single pipe for it so that will change im sure
