Petcock upgrade

Czakky · November 11, 2019, 07:47:27 PM

Looking to run a higher flow petcock on my R5 tank. I vaguely remember on the old forum guys putting Pingel valves but, I'm pretty sure there is no direct fit.

What's the cheat code?

I'm open to any recommendations.

Contra!

Pingles are really nice. Is your bike starving of fuel? I hear of people running with the stock petcocks without any issues with their modded bikes.

Trying to cover all my bases. I'm not sure where the stock petcock tops out.

No reserve on the pingle is the biggest drawback

DEPENDS ON CARB SIZE, FLOAT VALVE SIZE VS MAIN JET + PILOT JET AT WOT.

Chuck does a modified raptor petcock with reserve. Works good.

Only for 400's.
350's are different narrower bolt pattern...

My Pingle has a reserve.

yup. you can get em either way.

Anybody mount one to a 350 tank?

In doing some research there is a blank adapter plate that Pingel sells, unfortunately it looks like it might be a tight fit.

3/8" npt=9.5mm the r5 mounting holes are 20mm center to center, mounting screws are 4 or 5mm (?). It leaves me with less than 2mm between spigot hole and mounting screws. Not sure I'm too confident in that.

This is on TM32s with 280 mains Stage 2 Supertune treatment

thats plenty for support.

1mm = roughly .040", so lets say at 'less' that 2mm, thats roughly .070" per side. thats more than enough to support a petcock. 3/8" is a bit much though, just get a 1/4" or 5/16 strip of aluminum, drill 2 holes to mount, tap the middle for 1/4" npt, and use a 1/4" npt petcock. regular gasket material to seal against bottom of tank, case sealant, and stat-o-seal washers under allen bolts to seal up the threaded holes.
