You DID say you have a 2 gallon tank though, maybe it was just left over gas.
I know you said it's purring pretty good, but did ya get a power increase with the 93 and new head? More top end?

Well, to tell you the truth, its been sort of a combination of things. My mother-in-law passed away just over a month ago, and I have been staying home with my wife, because she was very close to her mom and she took it pretty hard.Also, the bike needed work done to it, and I tried not to take too much time away from my wife to do that, so it kinda got done in bits and pieces. I wanted it to be done close to perfect before riding it much, cause I'm starting to get really anal about every little detail. Yes, the bike does seem to have developed a bit more power. This may seem kinda strange, but I think its sorta like a break-in process with the high compression head. Here is why I think that. I did ride my bike a few times after installing the hi-hi head last month, but not very far. And it didnt seem that much different to me the first few times. Coming home yesterday after filling up, it still didnt seem that much different. Today, I went to the same place where I filled up yesterday to return some dvd's to redbox. On the way there, didnt notice much difference, except she pulled a little better. On the way back, I began to notice a definite difference in rpm's. I wasnt flying at warp speed, but I felt a little more oomph. I am betting that after a few more rides, especially a longer ride, I will begin to notice a bigger difference. Once I get out for a nice long ride, I'll take my speedo with me so I know exactly what kind of speeds I'm hitting, and I will report back.

Pictures didnt show up I dont think, but I will tell you this. It wont run good for long with a straight pipe. At first, it will seem like you have more torque and probably better speed. Eventually, what will happen is the open pipe will mess with the port timing. First you will lose power intermittently, as if your clutch is slipping or something. Eventually, you may lose power altogether. I'm just telling you the fact is that ported 2 strokes need back pressure to maintain proper timing.

they dont need back pressure for proper timing, timing is controlled by the ports in the jug and do no change unless you do port work. piston ported two strokes need back pressure to keep the motor from over scavenging the fuel charge from the cylinder.

I'm afraid Moon is right Big, I've been running a "fake" straight pipe on mine for MONTHS, YEARS if I include all of my bikes. What I mean by fake is that I take an old used stock pipe, cut the heck out of it, leaving the honeycomb baffle for a little back pressure. Just a peice of pipe with NOTHING inside (no pressure at all) will allow the fuel to flow directly through and simply spew unburnt fuel out the pipe. 2 strokes do enough of that without using a true straight pipe, add a completely unrestricted pipe and you double that problem.

I did a number of things today. Fixed a broken pedal (too cheap to replace them, plus they are vintage and I like them). Also adjusted my bottom bracket and my chain tensioner, which is on the pedal side. Lubed my chain, fixed a broken wire connector on my batttery that powers my brake light, put some air in my tires.
