Last night I popped out the brass plug over the pilot screw as well as installed the JT 44T rear sprocket. Took out 4 links on the chain and kept the piece/cleaned it up to use when I switch back to the 50 for family offroad weekends (yes, with an extra masterlink).
First impressions with the 44T/pilot adjustment after test ride last night and then the ride to work this AM--I like it pretty well! I can now cruise along at 65 mph in the 55 zone, which ALMOST lets me keep up with traffic...ha ha ha. At the big hill, I downshifted to 4th and it pulled the entire hill at 55 (which older Honda Civics seem to not be able to do), and it wouldn't do that in 5th with the stock sprocket. It would hold at 50 mph all the way up with the stock 50T, but 55 just wasn't there. Now that I also don't just have to hold at WOT the mid-range stumble is a little more obvious so I'm thinking...shim the needle. I haven't re-jetted for elevation and since I sit at between 7000 and 8000 feet I should probably drop down to a 112 to start. :-S Probably before I even try shimming. Most likely will still need to shim though, I'm guessing.
Almost forgot to mention that when I popped out the brass plug, the pilot was only turned out from the factory about...between 1/4 to not quite 1/2 a turn! I tried 2 1/2 turns out and it was a little finicky to start, so turned back in to 1 3/4 turns and it starts as easily as it did before...one kick. Also no more popping through the carb with throttle chop. :-)
Now that I can cruise at 65 I think the front wheel might need a balance. It feels a little "hoppy" but maybe it's just the stock crappy tread design. :-S
Thanks so far for the input guys! And even though the search function can be "interesting," this forum has been a big help so far.
