both are done actually if it was me I would do both the venting is pretty easy I beleive its in the tech articles and when you route the fuel line put the filter really close to your petcock and route over the manifold then down to your carb to keep it on a pretty steady downhill slope least that is what has been working for me

My experience was that I had a low fuel stumble once with the Suzuki valve. I went to the Grizzly valve soon after and I've never had an issue with it. Even so, I did add a vacuum (pulse) pump later... but that's just because I love tinkering and modding the bike.
Has anyone ever had this issue using the Grizzly valve?

Nothing is more irritating than a machine that won't work properly. Several times the pump left me stranded in hot weather. You know, 110*, full riding gear, and always an audience of other bikers. Stop to get a drink then come out of the store to see gas boiling on the engine case and flooded carb. It wont start until WOT, pipes popping, lots of black smoke,and everyone is watching. Not to mention the danger of someone flipping a cigarette down.

So.....I removed the not needed junk and went pumpless. Vented gas cap, stock, but new petcock and screen, automotive style glass fuel filter, new fuel line, removed the brass carb screen, and installed the Grizzly valve.

I'm extremely happy. Never an issue. And without a doubt the engine runs cooler. I rode 2up, loaded with gear, 90mph +, for 15-20 miles with no starvation. The fuel gauge is not very dependable anyway, so when I get down to 1/4 tank or the light comes on, I fill up. Or when it cuts out I flip to reserve then fill up. Not that big of a deal for me.


I could see how when the fuel gets below the pick up you could go slightly longer before a sputter due to the fuel in the extra 10"-12" of fuel line and the pump itself.

Went pumpless when I put the hsr 42 on along with a modified Nemesis manifold and a Pingle petcock.

No problems whatsoever and I have run it dry on purpose to see if I would have any problems with a low fuel level.

I didn't need to put the Pingle on, But it is a one finger operation to open or close it.

It also opened the engine up for better cooling when I did this

Do you have a fuel filter on the other side of the manifold, or is it just fuel line all the way to the carb inlet?

I just put the grizzly in about two months ago pumpless awhile back no problems switch to reserve about @ 180 mile mark on odometer. Guess I'll find out when I get back to mountain road riding in Co. nice steep climbs will tell me whats really happening.

Is the move looking more and more like a reality?

Yes! I will be hitting the road on the 20th of this month.

The best of luck to both your wife and yourself in Colorado. I thought I saw where you said Amarillo was home at one time. This will certainly get you back in the west.

No filter, The Pingle has a very fine screen on it and I never had a filter on any other bike I owned and the only problem I ever had was with water, Which will go thru a filter anyhow

Thanks coot.

I have a question about the pump less thing, Why do you have to vent the gas cap when there is already a tank vent?
