Oh here we go. It's impossible to say without being bias. I will say this, I never have to this day got Hendrix or the Beatles for that matter. My fav guitar player however is and always will be Mr Blackmore for his choice of notes and his tone.

Thats interesting Nic, I've seen Mr Blackmore twice and he was one of the messiest guitarists i have ever seen live...{John Lord was awesome 8)} Without doubt the best guitarist i have ever seen live is Steve Vai, he is a master of the guitar and just amazing live.
I have a couple of photo albums full of concert tickets from as far back as the late 1970's, first band i ever saw live was Thin Lizzy. Hendrix was innovative but not brilliant....

Well there you go mate, I never saw him live, he was known as a cantankerous ice hole and a total PITA at times. I saw a video where he threw a jug of water at Gillan, if he got out of bed the wrong way he would carry it to the gig that night, I know a bloke like that lol. Can't fault his recording though. The Vai's of the world are very impressive but I get bored pretty quick, Paul Gilbert's another one, magic to watch for a short time, this is just my opinion though. When Hendo was doing his thing I was into Fogerty and his guitar playing, E7 anyone BOYN ON THE BAYOU~~~~~~~~

I'm with Nic on this one, Ritchie's the man, or WAS until he went all medieval and started wearing tights. Do any of you guys watch/listen to Phil X on the Fretted Americana website?  Mad as a box of frogs but boy can he play! Listen to his "combined" songs where he plays Stairway to heaven whilst singing the lyrics to Highway to Hell.  Awesome.

Yes, Phil X, very talented. I don't mind that Ritchie wears tights now, I think he's happier than he's ever been and at his age he deserves it. It's a bit dull hearing the missus sing Purple tunes though.

I can't compare Gilbert and Vai, Vai's been doing it a lot longer and puts on a fantastic show as well, Gilbert becomes very repetitious to me, he is good though.. Vai's not just a shredder, he's an amazing composer as well. I should have said that the best guitarist i have ever seen live "technically" was Vai, he's not my favorite, i prefer hard rocking bluesy types like the Allman brothers, or even Ozzy's old guitarist Zakk Wylde, who has guest stared with the Allmans quite a few times, pentatonic shredders are the ones i like the most, kinda like blues on steroids.... ;D 8)

Wow. The thread really got away from me here... Sunday night I took the bike out
Around the neighborhood for 2 hours. Nothing changed. Then all of a sudden the bike was stuttering hard up until about 3k and then was fine. Well riding through the neighborhood it's hard to be above 3k so it was really jerky. Caused me to stall out for the first time. Bummer because my electric starter doesn't work an I can't kick it while sitting on the bike. Got it going again and got it in the garage. By really sure whee to go from here but I'm using it as a sign to finish the two guitars I've been putting off.

Every single item inside the carbs is new, so it isn't wear and tear but I'm curious if  dirty gas isn't clogging the slow jets. Or I'm fouling plugs and misfiring. Or I haven't set my timing. Or I haven't adjusted my tappets. Like I said when I goose the throttle it was fine it was only just as I have it alight throttle. Sounds like a carb thing but I have all the aforementioned things to do still. I also noticed my oil was getting pretty muddy  and murky already. I need to change it and run seafoam trough the gas and oil. Can't so anything yet until I get some money I am very close to flat broke. Just figured I would update and see what you all think.

I also still have the speedometer issue. I believe the cable is stripping inside the speedometer. Cable spins just fine but nothing on the speedo works. When I had it apart I could turn the gear by hand. It's like the square peg is spinning in a round hole. Can I just get a speedo gear unit and swap? I'm not dropping $200 on a new gauge :/

Maybe a float stuck, you were very clean to start with ! Very easy to check just drop the bowls

I have a question on your front blinkers. Why did you mount them on the head light bolts?

That's how they came to me mounted since they are k3 or later ears. I don't have the extra pins/bolts to attach the winkers separately from the headlight mount. When I actually have money to my name I may purchase the hardware I need to mount it correctly. I don't have money for new ears that's for sure.

Thanks for insight on the carbs. Read a few threads people asking similar questions. Gonna check my boots for a leak too. Lots to check and no time right now. These guitars will be paying future bills ;)

Sounds like plugged idle jets to me. Pretty easy for a bit of dirt or crud to clog up one of the tiny passages. It happened to me last year a couple days after I cleaned my carbs... I was thinking it couldn't be the carbs but ended up pulling them anyway eventually and I could see a small bit of junk in one of the pilots. Does it take a bit more choke to start that it did previously? Or more kicking while choked? This is usually a sign of clogged idle jets.

It's worth a check anyway. You could even do it on the bike if you wanted.

Since it was running fine and then just suddenly started doing this I wouldn't suspect that the oil has anything to do with it or adjusting the valve clearance. The timing wouldn't suddenly change, however, you could have a sticky advancer mechanism so check that. One problem may be that I don't think you can really check that very easily without pulling your points plate (and thus having to time it again when you put it back on). You may just be able to grab the timing cam (cylinder that sticks through the middle of the points plate) and try to rotate it back and forth. See if it wants to snap back into position or if it feels gritty or sticky.

I also wouldn't suspect spark plugs if it is only a low RPM issue. Generally spark plug issues would tend to be over the entire rev range.

Thanks IW good stuff to think about. Definitely something I don't k ow too much about. I would rather have 15 potential things to check so I can get used to diagnosing and fixing :)

I have a pamco electronic ignition.

sso one or more of my floats is definitely sticking. tried to fire it up last night and it started pissing gas all over the floor. could not trace it from the hoses as I was more concerned with cleaning and stopping the flow first. that hopefully explains my strage stuttering behavior. so now I have to determine why my floats are sticking when they are brand new. my first and unfortunate guess is the gas is gumming them up from the POR15 coating in the tank. I can't imagine there being that much debris in gas naturally to clog up the slow jets and make the floats stick. gumminess has to come from something not normal ie. the Por-15 coating. if this IS the case I'm not sure how to proceed. how can I be sure the coating is coming off?

it was really suck to try and recoat or just strip out the existing coating because of my fresh paint on the outside. I am 100% the application was done correctly, my tank was super bone dry before the coating went in. if it is failing it is failing though, no getting around that.

I also ordered the starter motor brushes, 3 8x14mm metal dowels, and a stator cover gasket.

Make sure the floats are not sticking to the gasket. New gaskets will swell. Had this issue and the fact I bent the float that got stuck to the gasket.

A sticky float valve won't necessarily make your bike run bad, just doesn't stop the flow of gas. 
Tapping on the float bowls will sometimes handle it or pull the bowl.
My 550 runs fantastic but occasionally #1 carb will overflow if petcock left on.
If carbs start leaking, turn petcock off and let motor run, the leak will stop in a min.
Does your petcock have a screen?

I reckon a couple of fuel filters would be a good idea. They'll block up eventually if your sealer job is coming off, or, you might just have a little bit of crap in the tank and filters will keep it out of the carbs.
I'm not sealing my tank, I just don't like the sound of it, I have a little rust that I'll treat but will also be adding filters. Shame to cut up my fuel lines but I think filters are essential with these old rotten tanks.

well I dont know if the liner is coming off, I have to check that (still working on guitars and cant get in the garage really). good to check the bowl gaskets for swelling. maybe I need to shift them or trim etc. I just think its odd that they (maybe just one) started sticking after 4 hours total of riding. this is all new to me. I make sure to turn my petcock off when not in use.

I will report back when I get a chance to drop the bowls and poke around in the tank too. I still have that terrible top dented bare k1 tank that if need be I can bondo it, prime and paint it, and not line it. thats the last resort as its going to take time and it will literally be the exact thing I did NOT want to do (wait on the tank to be done) thanks for reading and suggesting stuff :) now its like the bike is done but its not....slightly frustrating.

A carb leak is a very minor issue, easily fixed.  My K5 leaked too right after a rebuild and never did again.
Shine a really bright flashlight in the tank, maybe you are expecting the worst.
Always turn your petcock off if motor not running!

thanks Stev-o. yes I am anal retentive about the petcock. I just shined a light in the tank, doesnt seem to be any peeling or floating debris, just about 20 very small black particles. like grain of sand small, but nonetheless I can see them sunken to the bottom (very visible against the bright silver lining). i was able to take my fingernail and scratch against the lining on the neck of the gas tank and it did not come off or feel gummy. thats a feeling of relief I think.

It could be a tiny piece of the fuel hose too. My #3 pissed gas on and off and it had just the tiniest little piece of fuel line rubber that most have been working its way in to that perfect spot at the needle inlet

If it is leaking try taking the spring clip off, lowering the bowl just a little kinda wiggling it and put it back in to place. Sometimes this fixes it up. Give it a shot before you go crazy thinking you ahve real problems

Another trick give the bowls a couple good raps with the handle of a screwdriver. Can help if the bike sits more or less due to tuning and stuff

tanks for all the suggestions. I do jump to conclusions. I'll get working on this meticulously like I've done everything else. excited to get it roadworthy, the 2 hours I rode it the other day were an absolute blast. since my speedo isnt working I don't know how fast I was going but I got it up to 7k in 3rd gear. absolutely terrifying. puttered around the rest of the time. gotta practice taking off from a stop without taking forever and a day ;)

The small particals could be your issue, possibly from bad gas.

Sound like a carb issue to me. I will think about a little more and post later since I'm celebrating with a beer, but I had a misfire issue that drove me nuts after I switched coils and replaced the pickups on my Dyna ignition. Turned out I was getting some arcing from the wires to the frame. Easy to check looking under the tank in the dark with the bike running. ;)

Do you have filters? If not, I really think everyone should have them. Some of the old timers seem to be against them saying that the petcock screen should block out those particles ... I don't buy it. The 40yr old screens just don't cut it for an old tank I don't think ... even if it is lined.

Get some filters in there, pull your bowls, and clean your pilots and needles/seats and I think you'll be off to the races once again.
