heat exchange

[jack14r]

does anyone know how much can be machined safetly off of the heat exchanger?

[CRAZEDRXP]

Why would you want to do that? Just fill those holes in!

I just took almost 1/8'' off the front of mine to match the intake grate and did not go thru.

I would be very cautious of how much material you take off. The ride plate encounters extreme forces. It nearly has to support the weight of the whole ski when at speed, not to mention the pressure incurred holding the ski on plane.

i want to machine the ride plate to try to control the porpoise at high speeds,my rxp is undriveable above 75mph.

Jack, i am having the same problem right now. I'm going to try extending the rideplate back 2" I'll let you know how that goes.

kep us posted I want to move the ride plate or add trim tabs but I scared
of messing it up.

Find/buy one, and cut the thing down the center..............
Quarter it if need be...........
No more guessing then

As a side note:
I just priced a stock water box from my dealer today. He offered it to me at his COST,so he could see just what I was going to do to it

Jerry, setting the rideplate back further has crossed my mind too . I was thinking maybe 1/4 of an inch. have you tried shimming the rear of the ride plate down. I did that on my gsx around 3 years ago(I think I ended up at around 30 thousandth) and it made a big difference.because of the heat exhanger, any of these tests are going to be a pain.

You are right Mike. Rideplate modifications are not going to be easy.
I'm going to start with a 2" extension and then cut it down from there if need be.

I'll let you know how it turns out.
