Even with being a bit rich, first will always try to come up with a quick roll off/on. Second is almost the same, though you have to be trying. If i accelerate out of a turn low in second it'll pick the front right up and power out. 3rd does not require clutching but does take some body fitness. I can get it up a little but I'm too chicken scat to try to ride a wheelie far (bad experience looping another bike.) I'm also crazy rich somewhere in my tuning (tm36) so I imagine second will be even better once I sort it out.

I guess when it quits raining I'm going to have to put on my big boy pants and pin it in first without leaning forward over the tank... and see what happens.

Wish the jets weren't such a pain in the sausage to change. Had the 128 in there forever and the 132 seems better - or maybe it's the weather. Also ride anywhere from 1200' to 6000' in the same day which doesn't really help I guess.

Default 331/wheelies

I'm at about 3,000 feet, with air box snorkel removed, stock exhaust and carb with dynojet stage 2 kit with 124 DJ main (DJ kit instructions followed to the letter), and a 38 Keihin pilot, stock 14/42 gearing, stiffer Barnett clutch springs on otherwise-stock clutch, smog stuff removed and lines plugged or re-routed appropriately, valve clearances right in the middle of specifications, still running conventional oil for break-in (please don't start another oil or break-in flame war...). My Bill Blue 331 will power wheelie in first gear with absolutely no effort, no double-blip of the throttle, no sitting way back on the seat, no pulling on the bars, no standing up on the pegs, no weight transfer, literally just sit there, let the clutch out, and then give it wide open throttle and the front will reach for the sky, and then up, over, and behind the rear wheel...if you don't let off the gas ;-D. Second gear is a different story. I haven't experimented with it too much yet, but so far second is a little hesitant to power wheelie, although it certainly WILL with GREAT technique. So far it has done a couple mild wheelies (maybe a foot off the ground) in second while sitting. I've done a couple stand up power wheelies in second and they seemed easy. So far everything with this bike/build is going exactly according to plan and I'm getting exactly what I bargained for before I started this whole project! Gotta love it when that happens because, in my experiences, it's pretty rare lol!

Broussard: I don't know if anyone's mentioned it, or if you've thought of it yet, but I bet your setup would benefit from a Kehin 38 or even a 40 pilot jet. If you're still running the stock Keihin 35 pilot, I think a bigger one would make power wheelies easier. Also did you check your valves when you did the big bore, or recently? If they are really tight that could make power wheelies more difficult. Also there could possibly be some other factor such as a tear in your carb intake boot, or a clutch that's starting to slip a little (but not necessarily enough for you to really notice). Let us know what happens when you try it again! Oh yes and, if you didn't already know, these motors make damn near max torque right around 4k RPM, so three or four thousand RPM should be a sweet spot to get it done. Also it could depend on how your big bore kit was broken in. If you sat there under 4k RPM for 500 miles and under 6k RPM for another 500, plodding along at constant speeds, in sixth gear, etc. While I hate to say it but that could also definitely have a negative effect on the power your motor produces. If this is the case, don't stress it too awfully much. Your bike will be ok and probably still run several thousand miles, just with a little less power and with more oil consumption.


Oh yes one last edit before I go...lol. Again, not to insult you if you already know, but make sure you cover the rear brake when you're messing around like this. If the front comes up too high or you get scared or whatever, give it a dab and the front will come back down.

OK - 1st gear, 5000rpm, seated normally, no leaning... grabbed a big handful so I could really get the throttle wide open, and layed into it... then about sh^t myself.

I think the main issue is the woosie attached to the throttle.
