144 vs 155mm pump

[blitza]

so i'm wondering, has anyone put a 155mm pump in a superjet or blaster? after mad acceleration for surf riding..... and the first useful Yamaha post!

I got better results with a mag pump of course but yea....with good results..

so you've done it then? much of a task? seems to be reasonably easy to do, and should have a bit of gain.
