westcoast pipe instructions
anyone have a copy of the instructions for a westcoast pipe for a 650sx? primarily need water routing, but jetting info for this pipe on a non ported motor with a 44sbn would help too

To save you the headache of going over to PWCtoday.com.....
I'm going to be running a stock 650 X2 with a 44mm sbn, a/f intake, prok air filter
Everything jetting spec I have seen posted falls within the following.
Single motor 650 doesn't need a maxxed out sbn, run 2.0 for your needle and seat. For the spring you want the 80g one (I think it's silver). That'll put your pop off at right around 20-22psi (ideal).
Low I was recommended 115-120
High I was recommended 150-160
Harry at group K said he agreed with everything except the highs, he said bump it up to a 180. Sounds like that's the jet you should be running.
I ordered the needle and seat, a 117.5 pilot and a 160, 170, and a 180 main... I'll end up somewhere good.
