LOL you guys are too much....thanks sincerely. :) I commented last with a smiley never thinking anything of it. Sorry if I threw you guys for a loop.
Rimshot, I can give you lots of help here but it depends what YOU consider "faster lead licks" as well as what style you may be looking to borrow from. I'll take it you are most likely looking for rock stuff.
For example, I've always admired Terry Kath (R.I.P.) from Chicago. He was MY first dose of guitar lightning years ago. The Chicago Transit Authority version of 25 or 6 to 4 is absolutely frightening for the times.
Then there are guys like Joe Satriani that sound faster than they really are due to legato techniques where they pick one note and roll 3-4 notes in one shot. This is really cool sounding but takes a properly set up guitar as well as some finger strength because you need to play notes without picking all of them. When you glue some cool scales together and put some feel/bends and a style behind them, you can really come up with some awesome lead solo's. Another guy (most will laugh at me for this) who actually helped me to nail legato was Warren DeMartinni from the band Ratt in the 80's. This was one cool thing about the early 80's...there were some monster players that were getting good tones as well as some killer lead playing. The problem was there were too many of them and not enough good songs.
As Ben noted about the pentatonic scale, most of those guys used stuff like that but they really took it to another level because when then got done, for some you couldn't tell they were "as pentatonic" as they really were. A lot of my style is based on that too. But the key is to paint and tell a story while in that mode...and this is where it gets hard. The key is to try and not make your solos become too scalular. It's really hard and sometimes there is no way around it. However, if you add a little something to it so it doesn't sound like a verbatim scale you learn from a book (though some have used that and it's worked...the solo to Tom Petty's Refuge is all pentatonic to where it's almost right from a book) it at least masks the scale a little showing you have some style. :)
Anybody can show you scales and techniques as well as tabs. All that to me is like having a guy teach you how to use a compressor that you don't own on a song while using a console that you don't own. LOL! It's all moot until someone shows you HOW to apply this stuff in your realm. When you learn a scale, it's nice to know 2-3 different ways to use it and WHEN you would use something like that or it just remains a "practice scale".
There are guys like Yngwie Malmsteen that do the stuff Jeff talks about with the sweep picking...and he also picks EVERY note. This is super clean sounding but takes a decent amount of time to nail because in order to be fast and precise, you have to be slow and productive first. Unfortunately, playing guitar fast is sort of like being an Olympic athlete until you get the mechanics down. It's all repetition and memory. Most of all it's knowing something so good slow, that you speed it up because you're bored and know it well enough. The worst thing is going too fast too soon because then you can pick up habits that are really hard to break. So whatever you do, go into this taking your time and be selective with what you learn. Challenge yourself but don't talk yourself right out of learning this stuff. Some of it can really be disheartening. LOL! But again, it depends on what YOU are particularly looking for in the world of faster guitar passages.
If you like the bluesy side of the speed spectrum, a few of my favorites would be Gary Moore, Joe Bonamassa and Eric Gales. Really killer players (I'm sure you've heard of Gary...some of his older stuff was really killer) that use speed in a good way. Eric's first two albums were his best in my opinion and Joe is just a mutant. But until we can sort of gauge what you're looking to do, it's hard really to set you in the right direction. What players come to mind for you as far as "fast" goes? If you could play like any guitar player...or even a few, who would you name? Stuff like this helps us to see what direction you should be going in. No sense sending you to listen to Tommy Emmanuel or Michael Romeo from Symphony X if you're not into that style. Then again, go listen to Tommy anyway. He's absolutely one of the best players of our time. :) Good luck man.
