Blaster B1 revs but seems to lack full power.. anything would be helpful!!! thanks!

[jamesmcleod21]

so i just bought another B1.. it seems to be lacking power. it revs like it should but seems to lack power all across the board (low, mid, and top) it's still gets up and goes, but not like my other one (which is pretty much set up the exact same). really seems to be missing something.. any help would be greatly appreciated.. it has a riva pipe, factory w box, riva intake grt, skt trk prp.. compression is good... thanks!

are you sure that the props are pitched the same?

 

[jamesmcleod21]

i really appreciate the response...
no they're def not pitched the same.. the new ski has a 14/17 skat.. the other ski has a stock prop.. but the new one has less bottom, mid, and top.. if anything i would think the skt trk prop would help it out... is that the wrong pitch prop possibly?? other than the props the 2 skis are set up the exact same.

Sounds kind of what mine was doing. I found it to be the spark plugs. Change the plugs, if you have resistor plugs (Example: BR9ES) change them to non resistor plugs (B9ES). Yamaha used some coils that used resistor plus and some that didn't. Just give that a shot, spark plugs are cheap and easy to change.

gee.. wonder what fix he found?

Having the same issue?

I dicked around with mine for a week straight and couldn't get it right, then it started sounding like the pump was unloaded and it was bouncing on the rev limiter...

fouled plugs.

Threw new plugs in... like a rocket again.
