Factory Pipe jetting

[surferdude345]

So i got a limited b pipe and was wondering if everybody basically sticks with the jetting off factory pipe or not, This is on a stock motor- stock flame arresters - screen removed, pump gas.
Thanks

Use the jetting specs from Factory Pipe, it should work.

No, I have my own jetting spec's that i came up with for stock carbs. :bigeyes: I also use a jetworks valve on the waterline for the stinger feed w/using my timing curve set with the ADVENT cdi's :cool2: This is a kick ass pump gas/stock carb/freestyle setup that works really good!

I think in most cases the specs from FP lets you use the stock neetle and seat but I found out that is not the way to go. I got some jetting recommendations from Paul L that were alot different from FP and it made a big difference. I guess FP saves a little $$ by doing that...I dont know....

I have a mate who has a pretty much bone stock SJ with a limited pipe and flame arrestors.

The low speed jet was pretty much spot on, but he is now at a 152.5 on top, and I'm pretty sure he's going higher. A 2.3 N/S was used as well.

I guess you just have to tune for what your happy with, as I've seen others use stock jetting with the exception of the 135's (130's?) that come with the pipe.
