Reduce WaveBlaster B1 porpoising

[KPC]

1996 Yamaha WaveBlaster B1

Unless I'm hanging myself over the handlebars, I can't seem to keep it from porpoising at anything above 1/2 throttle, even on glass water.

Although most of my riding is burp, turn, burp, jump, etc.. there are times where I want to open it up just to get from point A to point B.

I've read about d-cut ride plates for improved handling, ride plate spacers for racing application, etc.. but in all the searching I've tried, I can't find someone that has discussed this exact problem for the blaster.

Any advice?

You would want an extended ride plate, a d-cut wouldn't help proposing.

Worx grate, extended ride plate and swirl...

you need to lower your ride plate in the back...put a thick galvanized washer in between hull and ride plate in only the rear two bolts...

while shimming the rear of the plate does help with porpoising, it can make the already-sqirrelly b1 get even more squirrelly.... in a bad way.

id get an extended plate. i have a protec on my b1 and porposing is not an issue at all.

An extended plate and a top loader grate to keep that pump hooked to the water .
