bikeman 940 with jaws big shark?

It should work great! We have them running on other brands of 920s and 925s and they rock! I think the 940 is actually close to a 920 cc. I thought it was 92.25mm bore and the RKT 925 is 92.5mm if I remember correctly.

Works great on the 925. I never ran the 925 without the pipe and can so I can't tell you what it is like just adding the pipe. I had a problem of pre-det when bleeping from WOT to get the skis down. That was cured by adding fuel to the 1,2 and 3 stages of the throttle in the higher RPM range on the BD fuel box. Was it worth the grand? Ya, only because I made them throw in a hat. Getting something for free makes you feel better. Good sound also. Not too loud but sharp. JMO
