Jetting Question

[papa_smurf49319]

So it seems very hardddddddd to get opinons about plug chops on here.

 

 

When someons melting down there bikes, or someone has a jetting problem the first question many people ask is did ya do a plug chop.

 

 

Ive been consistently trying to get info on a particular situation with plug chops.

 

 

My buddy and i are both having problems achiving a two millimeter smoke ring! It is chocolate brown but only measures 1mm to 1.5mm

 

Started out wit 155's and are now at 170's, is this ridiculously high for a motor with my specs?

 

Settin at 850 feet above sea level and its about 70 degrees out when we ride?

 

Bike has ran great with all the jets between 155 and 170's.

 

 

 

Thanks

well, some fuels, and even oils will affect the ring some....have you gone up untill it gets a wot sputter/breakup? that's usually about 2 sizes rich from what should be a 2mm ring

ya thats what jim from passion said, some fuels wont give you that nice smoke ring, it hasnt sputtered or ran any different but he seems to think we are way to rich?

im prolly wrong but do you think it could have anything to do with your timing being at +7?
