2000 GP1200R Rebuild

[Oleg Russia]

as far as I know this piece should not be there. And if you are planning to make a free exhaust, I would not advise you.

Did you also do the return line / drilling the carbs mod proposed by OSIDE? Trying to see if I use stock jetting or the recipe but keep accelerator pump intact and drill the air box.

thanks!

Here ya go

Yes I have heard the free flow is not needed unless you have a heavily modded motor so I am not planning to do that.

Yes I am planning to do the Oside recipe 125 mains, 110 pilots, 1.5 Needle and Seat, 95 gram spring. I was planning to disable the Accelerator Pump, Drilled Return Pressure Balancing Mod with a jet in the return on the #1 carb. I have not done the carbs yet but they are on the list to happen in the next month or two.

I need to see a pic of where that ? Styrofoam piece fits then, it has to fit somewhere.

[bainer1290]

Figured out where the styrofoam goes!

[WFO]

that piece goes on the right side (battery box installed) btween the hull and box

we usually discard those 2 pieces of foam

Sounds good thanks!

What's the best cooling setup for a stage 2 modified GPR with the holeshot kit installed?

As I will be using Riva heads I have 3 outlets on the heads along with the stock single pipe with 2 inlets from the heads.

1) I have seen some people use a tee to connect the 1st and 2nd cylinder, and feed the pipe like they do in a stock configuration from this 1&2 tee and the 3rd cylinder.
2) I have seen some have 1st and 2nd cylinder feed the stock single pipe and run the rear cylinder to a separate pisser overboard.
3) I have seen others only run the 1st cylinder to the pipe, cap the 2nd pipe inlet and then run 2 separate pissers for the 2nd and 3rd cylinder.

What's the preferred setup or what advantage does the one give over the other?

[WFO]

just run #1 into the pipe and block the other on the back of the pipe, then 2 and 3 overboard.

running the pipe hotter helps with scavenging
