Title: i know, i know. another jet kit question. Post by: gery350 on January 22, 2006, 07:32:26 PM i just got my son a z400 with a yoshi exhaust and i'm not sure the guy jetted it(he says he did). i took the carb apart(unrelated problem) and all i can see on both jets was what looked like a number 60 but not sure. does anyone know where i can find out what jet size it should have and what jet kit works well with a yoshi trs titanium?
thanks, gery Title: Re: i know, i know. another jet kit question. Post by: kfx400rob on January 22, 2006, 07:38:07 PM i think it was sposed to be a 150 mj? for the pro series
Title: Re: i know, i know. another jet kit question. Post by: Old_School on January 23, 2006, 09:09:12 AM Gery, I assume that's a Keihin carb? The 60 is a pretty big idle jet. I have a 55 on my zilla. It's a tad lean but doesn't Keihin go up in sizes like 2 then 3 (55,58,60, etc)? Does it pull on the top end or after mid range does it kinda fall on it's face? How is the throttle response from 1/2 to full? -Mark

But to be safe, give it a quick blast then shut it off and pull the plug and check the color. 2 strokes are easier to tell if they are running lean/rich by how much they smoke but 4 strokes are harder to tell. The spark plug test will tell if your jetting is good. -Mark
