Nice ride today

[89 burban]

Everything went good after the carb rebuild. New handlebars are nice! When i was going along at 1/8-1/4 throttle and gunned it, the ski would gurgle a little so i turned in the lows a little and it went away which was good. Got the tach hooked up but not sure how good it is at lower rpms it seems to be on the high side, but at WOT it reads about 6940 rpms. Brought the GPS but it wasnt working for some annoying reason.....

Porpousing is still an issue but its hard to get rid of when riding 2 up. The first day i had two thin washers in the front and one in the rear, making the ride plate almost even with the intake grate. With this setup the ski really porpoused. Today i took them out and just added one to each rear bolt just to try it and it seemed a little better...still does it at around 30-35 mph

I also got a riva extended steering nozzle from ebay

all in all it ran great!

yup i put in new batteries and now the speed works....grrrr


cant go out today, raining and thundering.....

What is the best way to shim the riva ride plate? i know i have to test by just having one rider

I mainly am riding on the CT river and its mainly flat to a 4 inch chop when its windy

should i shim the front or rear? riva says to not shim the front

what do you guys think?

shim the front so its just above the intake grate (two 5/16 ss washers) and add one or two of the same washers to the rear?

ive also stepped the sponsons and have protec trim tabs


thanks

If you are trying to prevent porpoising, the back of the plate needs to be lower than the front, this will keep the bow down.

ok and for most speed topend with one rider is it flush? or shim the front until it is flush with the intake grate?

[97GPSLEEPER]

For topspeed, shim the front down as much as you can without the plate hanging below the intake grate. My R&D plate hits the pump nozzle before it hangs below the intake grate.
