Lean vs Rich - 4T vs 2T methods....
Posted: 01:51 pm Mar 03 2016
I have been a 4T guy all my life. Every one of the many bikes I have owned (aside from a brief, disastrous and forgotten about venture with a RD350LC a very long time ago) have lived by the suck, squeeze, bang, blow mantra.
My KDX is my only long-term 2T ride. I am having fun learning more about 2T's as I go along, but jetting remains a bit of a mystery, and I think some of my 4T background may be hindering me..??
4T lean - blip the throttle from idle at rest - the bike revs soar quickly and they hang, taking their sweet time to return to idle.
4T rich - blip the throttle from idle at rest - the bike bogs instantly, and depending on how rich, either stalls or clears its throat and then revs rise.
Does the same apply to 2T engines?
I am using the jetting guide here on the site.
I think my pilot is right, or really close at least. I recently replaced my jet block gasket in case this was causing any issues that make jetting extra hard. Once the weather improves I can see if the bike is behaving better, or whether it's the same-old-same-old.
Any advice or comments are really welcome.
