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.
up up down down left right left right b a start.
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. :twocents:
yup. you can get em either way.
:twocents:
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. :twocents: 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.
:twocents:
The only dual output valve that Pingel offers is 3/8". Would there be much advantage over stock on a single output with a splitter?
single with a splitter is fine
Why not use 1/8" NPT or BSP thread? Or do Pingel only supply 1/4"?
easier to find a 1/4" NPT with reserve. bsp, not common here. ( I actually work in the valve industry).

I know NPT is the US standard, from endless issues with people mixing BSP and NPT on the offshore equipment I work with. Most all major hydraulic valve, pump and motor manufacturers use parallel thread BSP in their ports, due to the "wedging" action of the tapered NPT, which can cause minor deformation in housings.....
or sae ;) (at least here). I'm familiar with both, we get requests for BSPP and G thread on occasion, its just hard to source, which really sucks as we have missed out on a few good orders. as an fyi though, 1/4 bsp & npt 1/4 will interchange within 1 thread difference in engagement, that's the ONLY one you can really 'fudge' and get away with , ive tested it up to 5000 psi here . (air over water setup) :twocents:
boy did this drift off topic :dawg:
Well I learned something.
BTW my math was way off on the 3/8npt petcock. Even the 1/4"npt only gets at best 2mm of gap between screw holes....
