I've installed a stage tres dynojet kit on the horse but I'm curious if I should insert the 155 or 160 main jet? Dynojet states that for a stock exhaust with pod filters 155 should be okay but with any aftermarket headers or slip on, you should use the 160. Anyone had any issues with this dilemma?

you have pods and an aftermarket exhaust, so go with the larger mains, as they instruct.1978 GS1085.

Alright thanks guys! I was just double checking because I was having idle issues initially. I don't want the air to fuel ratio to be crazy.

even if DJ recommend those jets it doesn't mean that they will be perfect for your application. you may still have to fiddle about with jet sizes or needle positions to get everything right, but you will be in the ball park to start with, saves having to guess a starting point and spend a fortune on jets.1978 GS1085.

I'll try the 160s first then I'll drop down to the 155s if I lose power. Before I would idle very high (3k) and it wouldn't start up if left sitting for long.

Second, you don't necessarily change jets "because you lose power".
Do measured runs at specific throttle openings (RPM doesn't matter all that much, it's throttle opening), then inspect your plugs.
THEY are the ones that will be the authority on whether you need to re-jet.
