Just curious, it seems a goog number of guys installing a dynojet have nagging performance issues. Backfiring, hesitation, etc. Is the perception sckewed because this is a tech forum?

Anyone with a dj please respond as to wether you have problems or not.

 

Dynojet's instructions are bad, they tell us to put too rich of a needle setting. Stakk helped me get my needles right. I have been telling everyone I can to set the needle one notch leaner.

You always have to fiddle with jetting when something is changed. The more experience you get, the quicker you get it right.

I believe my 650 with a dynojet runs better than any stock one. I really don't think they did a good job with the stock needles. But, it took a little messing for me to get it right.

I would get the dynojet again.
