Title: Reserve Fuel
Post by Beagle on 05/13/13 at 08:23:52

OK, this is funny and I should have known better but I thought I'd share.  I took my Savage on a ride on Sat. and was going up a steep hill.  Suddenly, my motorcycle starts sputtering and I'm like, "WTF?!?!?!" and it dies halfway up the hill.   I was able to get over on the side of the road and tried starting it again but nothing.  Than I think, "Duh!  I'm out of gas!", so I switched it to the Reserve but it still wouldn't start.  Why you ask? It was a steep hill and I think the fuel wasn't flowing to the engine, so I turned it around and head down the hill and started it right up.   ;D   Now I wish they had a fuel gauge!  I keep forgetting about the Reserve.

raptor or stock?

Steep hills have a unique requirement of WFO on the throttle.
at that position, vacuum is at a minimum.
vacuum operated petcocks then to turn off.

switch to prime on hills or raptorize.

I have the stock.   It was just funny that I forget I was low on fuel and had to be reminded of that on a hill.  Doh! ;D

Simplest cheapest reminder to get fuel is a grease pencil. Write the mileage +100 on the mirror when you fill up. Rain or moisture will not affect the grease pencil marks, but they wipe off easily with a dab of windshield washer stuff and a bit of paper towel at the gas station. When the mileage on the odo gets close to the mileage on the mirror start looking for a gas station.
I have not even had to use reserve since I started doing this 2 years ago.

RYCA folks use reserve often,.. and we never get very far away from gas stations.

fuel pick is in the rear, the deep end when going uphill.

Life has a series of little reminders like this  ;D

Definitely swap out for the Raptor, it will fail at the worst time and you also get a little further before needing to switch to reserve.

I got a raptor coming for mine but I was thinking back when I was in my 20s I didn't always remember to turn the gas on when I took off :o, I wonder why I think I will remember it at my age now  :-?

Don't sweat it...I never turn my Raptor off except during winter storage.

Title: Re: Reserve Fuel
Post by Serowbot on 05/13/13 at 12:59:28

Every bike I've ever owned had a manual pet... never turned them off unless I was pullin' the tank or carb...
I think I've had 2 times when the float stuck, and they leaked...

...  but, (I've had 4 Savages with leaky stock pets)... :-?...

When the float sticks with a Raptor,.. you turn it off...
When the stock pet leaks,... what do you turn?... :-/...

Post by Dave on 05/13/13 at 13:02:03

It took me a little while to start remembering to turn off my Raptor, I finally settled on a system where I turn it off as I pull into my driveway.  I never forget now.

For the original question or comment on this thread....I offer the following comment.  When I was draining my tank and testing the flow for the Raptor and the original Vacuum petcock, I discovered a little bit about the fuel flow from the tank.  When the tank is full the fuel pipe and vertical screens are completely submerged and fuel flow is great.  As the level of fuel drops there is a point that only a portion of the fuel screen is submerged, and flow is drastically reduced.  When the fuel has dropped and only a bit of the screen is below the fuel level it may provide enough fllow for cruising on level ground - but on a climb, while accelerating or on the interstate at 75 mph it may not keep up with demand.  As the fuel drops.....so does your ability to make HP for extended periods.   When I did the Chaptor on the Raptor thread I commented it took 2 min and 34 seconds to drain the first gallon, and over 7 minutes to drain the last gallon.

remembering to turn on is not too bad, a sputtering engine will remind you.

remembering to turn off... well there could be issues there, the sudden need to change oil for one, not enough gas to get to the station another.

So, to remind you flip the raptorcock to off when you switch off, tie a rubber band to you key ring and hook it to the raptorcock when you put the key in.  might help you remember to turn it on too.   ;D

So, where's a good place to get that Raptor Petcock?

Title: Re: Reserve Fuel
Post by Dave on 05/13/13 at 13:45:35

Ron Ayers was selling the correct Suzuki one for less than $ 19....Here is the link.

http://www.ronayers.com/Search/N/687/Criteria/5LP-24500-01-00&adv=5&kw=fiche.ronayers.com

This is the correct one with the correct outlet size, correct offset from the tank, and brass inlet tubes instead of plastic.

Title: Re: Reserve Fuel
Post by DavidOfMA on 05/13/13 at 14:07:42

Just got one from Ron Ayers. Quick shipment, right part. Put it on while I bad the tank off to check the valves. Only hard part was getting the vacuum hose off the carb, where it was welded by age.

Using it sends me back to the 70s, which is the last time I rode until last year.

Title: Re: Reserve Fuel
Post by Badass94Cad on 05/13/13 at 14:34:19

Quick reaction is the name of the game...Same thing happened to me going up a hill one time, basically 2 pops and it quit.  I barely had my hand by the petcock by the time the engine quit, in gear mind you.  Then I had to maneuver to the side of the road, one handed, with the rear wheel locked.  ;D  Great way to start the day!

I hardly ever have to switch to reserve, but when I have, it's usually with more warning.  Going uphill gives you like no reaction time.  :-/

Title: Re: Reserve Fuel
Post by Beagle on 05/13/13 at 21:37:04

OK, for those mechanically challenged (like myself), it would be strongly recommended to get the Raptor Petcock to replace the stock one...however, it's a manual Petcock that you have to turn on before riding and off when you're done, right?  

I've read where it makes it easier to remove the gas tank too.  How is it easier once you install the Raptor petcock?  

This is the Raptor petcock I should get, yes?
http://www.ronayers.com/ProductDetails/N/687/SKU/808680

Finally, here's videos that show you how to replace the stock petcock wit the Raptor one:

Part 2 - http://www.youtube.com/watch?v=FUWI0ID-3so

Title: Re: Reserve Fuel
Post by Badass94Cad on 05/14/13 at 05:41:03

The Raptor petcock is manual, so you have to turn it on and off.  It is more compact than the stock unit, so if you have a clearance issue removing the tank, it should be resolved with the Raptor.  I didn't watch the videos, but it's a fairly simple and straightforward swap...2 bolts.  You probably couldn't do it wrong, but if you did, post pics.  ;D

The stock petcock has a vacuum diaphragm on the back that take up enough room that it hits the frame when you try to take the tank off.  You have to drain the tank and remove the vacuum petcock before you take the tank off.  The Raptor takes up less room and you can leave the fuel in the tank and the Raptor attached when you remove the tank.

Yes....the link you had for the Raptor is the correct one.

I didn't inherit my Dad's mechanical aptitude although I do sound like him whenever I'm doing something mechanical.  My wife hears a lot of swearing coming from the garage!   ;D

It actually looks really simple.  I watched the videos...2-screws, 2-hoses....should be OK.  

What is everyone using to stop up the vacuum line after the Raptor is installed?

Post by justin_o_guy2 on 05/14/13 at 12:26:33

Thers a hundred ways. I took about a 2" piece of dowel rod & put a dab of silicone on it to make it slide in. Silicone & vacuum arent recommended, but I dont think this is ever gonna suck out,,

Title: Re: Reserve Fuel
Post by Dave on 05/14/13 at 13:03:51

I just went by the Auto store and got a pack of vacuum plugs...they come with several in a pack.  I put one on the carb nipple, and another one in the toolkit as a spare.

Post by Boofer on 05/14/13 at 21:24:10

As for keeping up with mileage, I just remember the last three digits when I fill up. I have not ridden as much lately, so I sometimes forget. I generally check my gas and oil before I leave on a ride. I rode last Wednesday (Five days ago) and filled up at 115 miles. I see it as 1:15 on the clock. Sometimes if it's within a few miles of 25, 50 75 or 100 I just round up to those. Works for me. With the Raptor you get a little further on a tank and a little less on reserve. Of course, here in the South we have a station literally every 15 miles at the most. I know this is not the case for some of you guys. Plus there is always the lawnmower gas on the carport of 50% of us down here. I would ask first and offer to pay for a splash and run, of course.   :)

The stock petcock has a vacuum diaphragm on the back that take up enough room that it hits the frame when you try to take the tank off.  You have to drain the tank and remove the vacuum petcock before you take the tank off.  The Raptor takes up less room and you can leave the fuel in the tank and the Raptor attached when you remove the tank.

Yes....the link you had for the Raptor is the correct one.
[/quote]
At lease on a 2007, you can take the tank off without removing the regular petcock, though you have to lift, pull back, and wiggle the tank to the left before it will clear the frame. Much easier to do with the Raptor installed, though. And now off is off and on is on, which my ancient brain finds more logical. I used a rubber nipple from Autozone to block the carb port. I think it was 7/16th. Fit perfectly.

On some bikes you can wiggle the tank a bit and make it clear - on others you can't.  It is not a year issue - it is more an issue of manufacturing variances....some bikes just have more room to clear the frame than others.  On my 2007 the rear of the vacuum petcock hit the frame rail.....it could not be wiggled off and the petcock had to be removed if you wanted the tank off.  There have been previous posts from owners that have had several bikes.....and they commented that on some the tank could be taken off with the petcock still on....and some they could not.

With the petcock I got I had to raise the tank a little to get the fuel hose to clear the choke after I had it installed.

7/16 is .437. I measured mine and the OD of the shaft is .220. So I believe the 7/16 will be way too big. :-?

Title: Re: Reserve Fuel
Post by DavidOfMA on 05/15/13 at 08:45:00

Have to check when I get home. Must have been 7/32 (which would be a perfect fit), unless for some reason that manufacturer is referring to the OD of the nipple.

I am just waiting for the Raptor to get shipped to me.  I guess they order it from the vendor and then the vendor ships it to them...and then finally they ship it to me.  (sigh)  So, maybe I'll get it next week.  No worries though!  We've been getting rain almost everyday, so I'm not going to go riding in the rain.  :)

If the tank's close to empty, you may not even have to drain it. I ran mine down to reserve and was able to make the swap just by tipping the tank.

The only way I have seen it screwed up......is when someone used regular washers to install it.  The screw threads do not seal into the tank, and fuel can seep past the threads and screw head if you do not use the sealing washers.
