thanks that all helps so the tps connects to the cdi and i ask this is because on mine i have a cv carb and i want to switch to a fcr and so far that i have found ill need to upgrade my cdi to run the fcr carb on my cdi it only has a single port and wont have the extra for the carb so is this correct?

 

I guess as I've never swapped carbs on the Outlaw at the shop. Had enough problems just keeping the Outlaw and the Predator repaired and running from all the crazy people that bought em..

 

quick question on jetting my carb my evelation is around 2,600 above sea so what size jetting should i use i have a silp on and filter w/out lid?

would jetting be the same for both cv and fcr carbs

 

Two different types of carbs. Jetting will be different along with other things. If you're getting a new carb designed for this use it should have some sort of jetting guide.Plus this might be able to help you.carbkie.html, Keihin FCR Carb Tuning Procedures
