Odds n Ends / Re: Gun Owners?

Sweeeeeeeeeeeeet  :D

I'm jelly. I haven't gotten to go shooting for a long time  :cry:

It was the first time I'd gone shooting in something like 5 years.  Definitely overdue.

Of course, now that there's an ammo shortage I probably won't go again any time soon.  5.56 and 9mm are practically worth their weight in gold right now, so I'm sitting on my remaining rounds for the time being.

Thanks for the write-up on brake bleeding. It's something I've never done before, but will have to in the near future.

General GS500 Discussion / Re: Petcock set for Prime to run reliably. Is this an issue?

Also gets stuck at high idle or does not immediately come down from a wot snap.

This is usually a sign of a vacuum leak or otherwise a very lean running condition.  If it isn't getting fuel in the required volume this definitely makes sense.
 
If I put it on Prime,  It runs fine and I go around down no problem.  When I stop I set if back to On.
I cleaned the diaphragm,  I might replace the frame mounted petcock if I find one at a reasonable price.

If the petcock itself isn't the issue, it may simply be the vacuum line that actuates it is clogged/kinked.  Easy enough to test by just disconnecting it and seeing what happens.

The big question is:  Will there be anything wrong with running it on prime all the time. and shutting off when stopped ?

Other than the fact that it's bypassing/ignoring the actual problem?  No.  It won't harm anything, unless you forget to turn the petcock away from prime and your carb float valve is worn or out of spec. 
In fact, on both of my GS's my solution to petock issues was to remove the factory petcock entirely and replace it with a simple in-line ball-valve.  Unless you feel like getting creative with fittings you'll lose your reserve capability, but unlike the factory petcock a ball-valve isn't going to just break on you.  Even for someone that doesn't have experience with simple petcocks, it's not hard to learn an extra step in the start up/shut down procedure.  In truth, the MSF still teaches to manipulate the fuel valve when applicable.

General GS500 Discussion / Petcock set for Prime to run reliably. Is this an issue?

Good day,

Hey , I am taking a break from troubleshooting , just getting out and riding.  I bike a rescued had a horrible fuel rust problem 1993e left with water and bad fuel for 6 years, tank rotted out and fuel lines contaminated for years.
I replaced the carbs with used ones and rebuilt them just in case.  Replaced the fuel lines and replaced the fuel take with F version.
Vacuum line is connected from carb to frame mounted petcock.
Frame mounted petcock and tank petcock were cleaned of a white calcium looking substance.  All fuel line mounting tubes are clear and flow liquid. 
So here is the issue.  The fuel does not flow properly in on or reserve settings.  If I squeeze the feeder hoses for main and reserve from tank when in the on or reserve setting I feel a pulsing. 
The symptom is that the bike does not rev above 4,000 rpm , idle is ok,  and fuel starves after about 3 min of running. Also gets stuck at high idle or does not immediately come down from a wot snap.
 
If I put it on Prime,  It runs fine and I go around down no problem.  When I stop I set if back to On.
I cleaned the diaphragm,  I might replace the frame mounted petcock if I find one at a reasonable price.

The big question is:  Will there be anything wrong with running it on prime all the time. and shutting off when stopped ?  I have had bikes for years that have the regular on or off petcock, and I religiously turn them off when I stop places.  Is this any different just letting this issue go ?

Just curious.   At the end of budget so not looking to pay more than $30 for a new one, especially if this will not correct the issue.  Just like getting on the road for some riding.

Knocking down the list another notch.

Bled the front and rear brakes.

Covered up the paint before starting the job... brake fluid sucks.

I used a vacuum pump for drawing fluid samples from compartments. It works better than the mighty vac for brakes.
Bled the front about 3X more than necessary and it still had a mediocre feel at best.
Let it be and bled the rear. When the front brake lever was squeezed a half hour later... it felt very good.

The brake lever also was squeaking and annoying. A few squirts of spray lube (cable lube) and it quieted down.
 




The rear brake had a good pedal after replacing pads, but the brake fluid was old.



 
First the reservoir was sucked almost dry by dipping the vacuum hose into it. (no photo of that)
 
Then four refills, vacuumed out the rear caliper bleeder and it was almost clear.






Nasty old fluid removed.



Just a small job but the bike had no front brake and a grinding, metal to metal rear brake when it came home. Finally having working brakes is kind of a big deal!

Oh dang, been a while.

Well, since last year I put together a handy little carbine, spent way too long debating on optics and stuff, but finally got to shoot it for the first time today.


For anyone interested in the specs:

Bravo Company 11.5 pistol, enhanced lightweight profile barrel, MCMR (M-Lok) rail, Mod 0 compensator, Mod 1 grip, KAG, and rail covers
Scalarworks PEAK sights
Trijicon MRO "Patrol" on a Scalarworks LEAP lower 1/3 co-witness mount
Geissele Airborne charging handle
V-Seven magazine release and bolt release
Arisaka Scout 300 light with a Malkoff emitter on an Arisaka inline rail mount running off a SureFire SR07 pressure pad
SB Tactical SBA3 brace

I think I hit the jackpot on this little guy.  My friend at the range had two ARs that we compared it to:  A 16" Ruger AR-556 and a custom built 7" pistol.
For some reason my BCM felt like it had less recoil than the Ruger (possibly due to the compensator?) while being a little handier and quicker on target.  While the 7" was fun it was really blasty and a little harder to handle because of it's tiny size, you kinda gotta scrunch up behind it.  The 7" is definitely more of a range toy, and while the 16" is likely more accurate than my 11.5" it didn't seem practically so.
This BCM seems like the perfect little fighting rifle.  I might put a Geissele trigger in it but the stock BCM trigger is pretty decent.  Also probably put a SureFire Warcomp on it, but only because I want to get a SOCOM suppressor eventually.

Woah!  When did this get moved to the Odd and Ends section?

Damn, been away too long.


Nevermind, wasn't paying attention apparently. :technical:

General GS500 Discussion / Re: Knight Designs LLC lowering pegs
« Last post by Bluesmudge on September 23, 2020, 09:07:12 AM »
Is there enough adjustment in the brake lever to put it in the right spot?

On the GS I prefer the pegs be pointed forward rather than level with the ground. Since, even with lowered pegs, your knee isn't at a 90 degree angle so your foot naturally ends up slightly angled on the peg. Angling the peg to match your foot gives you more contact with the peg.

Those look good on the bike!

I almost ordered those for another bike, a BMW, but just wasn’t sure about fitting. Ended up paying a lot more for lowering adapters from Suburban Machining.
