Other pfp water box temp

[smrbum]

after riding for a few minutes my water box is sizzling hot the rest of the pipe is fine ,just woundering if this is normal or what could be wrong

think thats normal Bill

but you can change the jet in the restrictor on the stinger too

mine runs at 100 - 120 deg C , pipe is somewhere nearer 35 deg C, adjust flow valve or change jet in stinger to tune temp

thanks guys

yeah, mine was pretty hot too. I opened up the flow valve all the way and it helped a lot.

anyone have good pipe tuning specs for the PFP? wondering what the optimal temps are for the pipe/waterbox to run at for max power?
