Knowpig Posted December 6, 2007 Report Posted December 6, 2007 I am looking for some jetting advice on the Alien system. Bike is an '06 Stock head I think it has stock reeds. Stock carbs. Pro-flow adapter w/K&N filter & outerwear No lid. Has the 6 clip needle. Running in Glamis. The problem I have is this- The jetting instructions say 30 pilot and 280 mains........with the lid ON. They recommend 320 mains with the lid off. That sounds a bit fat. Do I really need 320's? It has 280 mains now and it felt lean. Raised the needle 1 clip and put 2 strips of duct tape over the box to get it smoother. What do you guys think? Quote
wesw Posted December 7, 2007 Report Posted December 7, 2007 4th clip on the needle and 310s would be a good start on the mains depending on temps and elevations. Quote
Knowpig Posted December 7, 2007 Author Report Posted December 7, 2007 That sounds like what I was thinking. I was thinking 300-310. 320+ just sounded like too much. I'll try it out. Thanks for the tip. Quote
