Hi all,

Still having issues with my jetting.

I'm running the Dyno Jet kit and wondering if a 160 main, 3rd clip on the needle, and 2.5-3 turns on the AF screw is a good place to start?

Is going down to a 155 too lean?

Having trouble starting it and unsure if its jetting or not. Starts fine once its been warmed up.

I'm about 350ft above sea level and temperatures are typically about 1-5*C in the winter, and 15-25*C in the summer.

Cheers

Hard start when cold is almost a sure sign that the valves need to be adjusted.

That jetting may be on the lean side with a pipe and intake but it could be rich if you are stock. that spends on on your pipe and intake. What do you have.

I agree with Leo, usually if they are hard to start when cold, its a valve lash problem (or a plugged pilot or starter jet).

Im running a standard airbox with a K&N Panel filter, and a slip on Pure Polaris exhaust.

Does the jetting sound off for that setup?

I'll check valve clearances tonight.

That sounds about right. I would start with the valve clearances then try jetting up, run it. try jetting down run it but only after the valve clearances are dead on.
