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

So that's what them plug's connected to the bottom side of the carb's are... I had no clue and could not find any information on them..
Do I really need them operating ?

I had 1 of those. I stayed to the factory jets. The problem with that sled is it may over heat and bog with no power. To fix it I pulled out the thermostat and cut the guts out of it and put the remainder back in ( the spring and moving parts ). Disconnected the tors ( plug the wires in to each other on the harness to complete the curcit). Mine ran great after that. Hope this helps.

Also I never ran the sled with the carb warmers on.
