Main Jets

#1 PostAuthor: Mick Hayward » Wed Feb 18, 2009 5:36 pm

Hi All

Does any kind soul have a set of 115 main jets to fit 28mm Mikuni VM 28SS carbs. I'm in the process of trying out some free flow air filters on my ST and am uping the mainjets from 110 to 115 (might work)

Thanks

Mick

I'd start at 125 or more to be safe :??
And on the 7th day... Zeds were created!

You'd expect about a 10% jet increase coz of K&N's.... , so try 122.5's :wink:

Trial & error, but if running weak.... Holed piston :shock:

Zeds were set up a bit lean as std anyway :!:

Thanks Pigford

I understand, best to start out too large than too small, dont fancy doing too many changes though. Be nice to get it right first time. I wish eh.

Regards

Mick
