Hello, my good sirs.
I've been quiet for a while, but Stella and I have continued to slowly rack up the commuting miles. 3000 since purchasing her in September.
Here's a bit of an update on how she's doing.
Way back in February I started the process of zeroing-in on Stella's preferred jetting for her stock 76/77 BS38s, OEM-style K&Ns, and stock exhaust. Beginning with stock jets, needle, and needle position, I've been going up step-by-step on the main. With both the one- and two-ups I felt an increase in power over the last with no discernable breakup through the mid/main transition at full throttle. This improvement was huge on the first step, less so but still there on the second. There was no significant change to MPG.
The 127.5s (2up) felt good, no complaints at all. I ran them for quite some time, but recently bumped up to 130s to see if I could feel the tell-tale breakup. Nope, still can't feel any. But, the bike does seems to vibrate a bit harder at all RPMs including idle. Maybe just a touch more power, maybe. The exhaust note might be a tad lower, but she's always had a pleasant growl. I don't know, it's all so subtle. I'll run them a bit to get some numbers on mileage.
That's going to take some time, though. This busy season is just about over and I'm headed to the woods for three weeks. 'Tis time to re-create this weary soul.
