MackDaddy: I've been running 42/125s with Thruxton needles and no shims and the set up is pretty good (Long Cannons, stock airbox, K&N filter, homemade bellmouth) but it always seems a tad lean if I try to hit the rev limiter. If I was to go back to the stock needle I think I'd at least have to put in 135 mains. We're pretty much at the same altitude, I'm around 1000ft at home and it goes from 800 to 2000 ft here where I ride the most.

Did you spring for the billet tips?




Oh man Ed, you just had to throw some more in the mix, eh?!

Well, maybe I'll try my original thought then. TBS needles, 42 pilots & 130 mains first. See what she does... read the plugs like a good wrench should.

I didn't spring for the billet tips... yet. Probably won't take me long before I bite the "billet-bullet" and get them. For now, they look & sound so darn good I'm pleased as punch.

Thanks all,
Jim

PS - Keep the variations coming. This will be a good reference thread for contemplation.
