two stroke jetting
I was curious on how you tell if your carb is jetted properly I have over the years changed out parts as the stock ones have worn out or got tore up including pipe and silence, reed petals & top end I have never really had a over heating problem or plug fowling problem but bike is hard to get to idle.

What kind of bike? Jetting 2 Strokes depends on if stock pipe and siencer is used, where you ride. The C clip on the needle usually is a good pace to start for idle.

Aftermarket pipe and silencer should br jetted richer. On my DRZ 400 E, I went from 47 main to 61 main with FMF silencre and powrbomb header, ported and polished head. I would do a search on Thumper Talk Forum in that area.

I've used Spankey's Jetting guide for years. It works very well when followed. It doesn't matter that it's on a Kawi forum... same procedure.
Here's the link.
