Oh, I also made up a plate to cover my registration sticker for video after I finished playing with those main jets. Not that you haven't seen my reg sticker a million times, but also to differentiate the MHR vs the Peace for video. Malossi wins the sticker battle by a mile, but with a bit of masking tape, spray paint and time I managed to roughly represent Peace Pipes on the opposite side of the plate.

Drop the pilot down a size and see if the mid picks up Can also pull the clip down one spot to try and see what happens either good or bad.
Or get a needle with the same small diameter but a larger upper diameter and a more aggressive taper.
You CAN have it both ways.. it just takes a whole lotta effort... and needles.

I was doing slider weight test runs all afternoon. 40 miles worth. I've got video of 16 acceleration runs to time and average so I can figure out what the scoot truly likes vs my perception. The dude that lives near the spot that I used probably thinks someone was chopping down trees with a hopped up saw in the woods next door. What I can tell you is that the max RPM according to the Vapor was 13,750 and that shit is entertaining. Not that it's all that much faster, but it's an experience, especially if you've never rode one that revs like that. Actual RPM that it stayed at anytime was prob just over 13,000 somewhere. I rode through town for no reason other than to rip it in town for my own amusement.
I do have a spot where there's spark knock, but I think it's one fairly specific spot. Maybe 1/2 throttle? Not sure since my marks have worn off. At this point I'm not even worried about it. I may mess with it more later, but the goal ATM is to get it running well so I can try to race myself before too long hopefully. Part throttle isn't really needed for that.

The lightest weights that I tried yesterday (5g) actually did the best. I thought it was just screaming and prob not going any quicker. Looks like it was sticking around roughly 13,000-13,500 for those 0-50s. I'll be surprised if it continues to pick up, but I'm gonna go try 4.5g to be sure. If that goes the wrong way, I may mod some weights to try 5.25g. Yesterday I tried 7, 6, 5.5 and 5. 6 & 5.5 were the same on all average times (0-30,40&50), but 5s improved 40&50MPH times. Not sure that my 0-30s are going to get much/any better without clutch work/replacement or maybe not at all. I think my modified stock clutch was working well enough to get close enough to the power of the Peace Pipe on launch, but could probably use a bit later engagement. Even the Peace Pipe could prob go harder 0-30 since it does take a second to get to the powerband. It's just going to have to be close enough for now though. I'm not sure that the front tire would stay near the ground (or that the belt wouldn't just slip) with anything I tried anyway if it could get to the power immediately and I suck too much to ride out a big wheelie. From watching some other people with hyper race stuff, I think a lot of people actually slow themselves down by going faster because it gets to a point that you either have to hang onto it while it's in the air or figure out how to get the suspension/frame to better control it or work the throttle if the tune is very aggressive. Imagine a hyper race losing to a rental because it's like riding a bucking bronco.

4.5g was essentially even with 5g. What I can do since I film to time is to see RPM too. I noted RPM at 30, 40 and 50MPH accelerating WOT. What I see is that my first run of 4 is usually the highest RPM of all runs. Then it settles down a little. With both the 4.5 and 5g tests, the higher revving first run is the slowest of all 4 passes. Then with the 5.5g sliders the first run is the quickest of the runs and then it slows a little once RPM drops.
I guess if I wanted the quickest light to light racer, I'd prob choose one that runs the strongest on the first pass or at least err in that direction, going just slightly heavier than the average best.
Right now the data seems to show that it likes something around 13,200 - 13,700RPM the best.
If I make up 1.5g inserts for my 4g sliders, I can try 4.75g and 5.25g as well. I have a feeling that people on any route to my test spot are tired of hearing this thing screaming by now, but I think I'll do at least 1 more set.
Oh, max RPM with the 4.5g was 14,090. It feels like it's going to come apart to me. I'm putting around a 35-40MPH most of the time, still over 10,000RPM.

I've tried out 5.25g and 4.75g. I've spent way too much time recording and reviewing RPM and elapsed time. I think my best choices for acceleration are 4.75 or 5g. Those and the 4.5s are really close. Differences of 0.1 sec in one place or another when averaged. The 4.75 or 5g should do better on a cool pass. By cool, I mean the first drag run. The CVT is hot, from riding 4-5 miles to the test spot, but it hasn't been beat on with acceleration runs. I think the 5g may actually be just a tiny bit quicker light to light if the lights are spread out just a little. If it's warm/hot out and the lights are closer, then the RPM on the lighter weights may drop more and be advantageous. Hard to know.
The total range for best passes seems to be 12,600-13,700. After looking at more and more, I think probably 13,000-13,500 would be a good number to try and stay around.
I rode around a little to go do a flyby pass that a YouTube commentor requested in the next vid. The vibration is kinda nuts. Putting around at 10,000RPM and then goosing it up near 14,000RPM produces vibes that I'm not used to. I guess just the frequency feels strange to me. It's also disheartening, in that I feel like nothing can be expected to last like this. Even if all else is great, I wonder if the stress of RPM may be the actual thing that makes a hyper race terrible on the street. The aggressiveness is up there too. There is no leisurely ride now. It's fun to play with. It would be fun around the car shows (that I doubt will exist in May). I'd have fun around town. I had more fun on the back roads with the Peace Pipe though. Holding this thing at the RPM it wants to turn to cruise 50-60MPH just doesn't feel right.
I did see 70.5MPH today. The tail wind was strong though. I think I could have done about 73-75 sitting up. I had to let out because I was headed into a tight turn with both bumps and gravel. When I went to do the flyby pass, I had to ride around and find a wooded spot because, even with mic fur, the wind was maxing out the audio.
I had planned to race myself this weekend, but I think the weather is going to ruin it.

The meteorologists may have been a bit dramatic. It wasn't too bad today. Rain early, but then it was cloudy and kinda windy. Decided to give the me vs me race filming a try. I loaded up the truck inside and out with tripods, cameras, tools, cones, riding gear, etc... Even tossed the air compressor in the bed. I really need to get an electric impact. I hurt my back lifting that damn thing in alone... then realized I should have just pushed it up the ramp like the scooter. Anyway, I don't even know how much time I've spent thinking about this lately. I had a supplies list made up and a to-do list to make sure I didn't forget a step whenever I got to film. Rode about 30 minutes to a spot by a power plant with a dead end past it. Here's my little setup. Should be very close to 330ft (1/16 mile). The hill below the highway right behind my makeshift drag strip just happened to be in the right spot to shield me from a lot of the wind. Right after I finished getting the cones and cameras setup, 2 people came down the road walking dogs. The cones seemed to create a line that they didn't feel comfortable crossing. They walked up near the line and looked down at me for a bit before turning around and walking off. Works for me. I did a few passes and shots with the MHR. That thing wanted to get nasty today. The first couple of times that I tried to launch, I had to get out of it because the front wouldn't stay down. I had to sit as far as I could forward on the seat and lean as far forward as I could to keep it down so I think the tire was just skimming the ground. Not sure if it was the weather or the fact that it didn't have to ride 4-5 miles to get there so the CVT was much cooler than normal. Kinda showed me how close this thing is to the edge of really being a handful. I'd hurt myself sooner or later if it launched that way all of the time. Then I headed to my mobile pipe swapping station. I changed the main jet, swapped sliders and switched to the Peace Pipe in about 15 minutes total. One of the only times that spending years doing quick tuning swaps finally pays off. Probably would have been closer to 30 without the air power. Right after that, a full size Chevy truck headed toward me. Crap. I figured it had to be someone from the power station. I walked out to meet a man in his 60's who said he came out to see what's going on out here. I told him I was just filming the scooter going up and down the road. He said he tills the fields on either side, and I told him I definitely was not there to tear anything up. He said "Well, the road is a county road anyway, so have fun" and drove off. Nice. Guessing he either thought it was a dirtbike ripping up a field or a chainsaw cutting down his trees before realizing it was just a scooter dork. I did notice that the camera shot looked to have moved just slightly and I had a 10lb weight hanging from it so it was not wind. He was squeezing by everything so I'm not sure if a tripod leg could have got bumped or something. Hopefully the finish line view isn't ruined. Did the Peace Pipe tests after that. Then packed up. 2 cars came and parked there as I was tying the scooter down and about to leave, so that was good timing. I was there for 2hr40min total. Probably all of 30-45 minutes riding or working on the scooter. Otherwise, walking up and down the road and playing with cameras. If nothing else, I got plenty of exercise. Also staring at the sun, waiting for it to hide behind clouds. It was interesting to ride the scoot in such close succession with the 2 exhausts. I must admit that the Peace Piped setup does feel quite mild after getting used to it screaming and especially with how it wanted to launch today. That said, as soon as the Peace Pipe was on again, I was doing little wheelies while returning to the start line. It's so much more predictable and controllable to me. Maybe I can get used to it, and it may not bother a good rider, but the MHR at very low speed is way aggressive snatching the wheel up as I'm used to with the Peace Pipe. All I've done is very quickly overlay the start line camera shots and apply a rough mask to see if they lined up. Pic below. It will take a considerable amount of editing time, plus I still have to finish up other stuff for video. BTW, I listened to the flyby pass from yesterday. It sounds pretty damn good IMO. Between that and hearing the Peace and MHR together, put on some headphones whenever I can get this vid up. At least I enjoy what little I've heard so far. Sorry if I've bored everyone with my rambling about this little project. I was just excited about trying something different. That said, don't hold your breath for the next one. There's a reason that you don't see people doing this often, and a reason that most people would not go do this alone.

T2 sounds SO good. And almost 70 sitting up. Great job. And my Yasuni R did the same thing; changing colors on the header and stinger. Personally I think it gives the pipe character

Great video and drag race!!! Personally I think the Polini pipes are the longest lasting before the clear changes color. For whatever reason handmade pipes with oil occasionally are the loooongest lasting. They stay new forever.

The overwhelming response to that last vid has been great, but again I've got a few people that think the scooter sucks (slow) and my tuning is all wrong. Clearly I didn't put enough effort into the CVT tuning, because my weights are wrong. I would love to see the amount of data that they collect when tuning to compare to mine. I don't think most people that aren't actually going out racing bother to do what I did. The Malossi exhaust is wrong. A few people said that no one thinks the Malossi pipe is the best. TPR, Roost and Js Engineering were mentioned. Never heard of the last one. Either way, I don't think I'll get so much from a different pipe that it's worth another $400 exhaust. If someone wants to start sending me these things, I'd gladly try it, but so far the best I can do is a discount. I'm grateful for that, but the parts still are not cheap. Mixing 4g and 5.5g sliders is all wrong. One guy says his 86cc runs 11.6 in the 1/4, so I told him it sounds great and post a video since there's nothing on his channel at all. Another says I need to wrap the header to encourage overrev because I should be seeing 14,000RPM with good power, but I remember this so I will leave it be. WOW!Strange that pipe wrapping just came up on KiwiBiker,,the latest is to only wrap the diffuser and belly as Wobbly stated here; "Effective cooling of the Ex duct is certainly effective , with the proviso that using the coldest water entering under the duct is NOT the way to go. Wrapping the header is proven to promote deto due to the returned mixture in front of the piston being overheated , ruining the trapped charges effect. But wrapping the diffuser - and then wrapping the mid or tailcone , would for sure have a positive effect , if and only if , the result was that the average pipe wall temp was maintained close to that as was tested on the dyno. You could then extrapolate that, and I agree Ken , that designing , then testing pipes already wrapped on the dyno , would increase retained heat energy as well as protecting the pipe surface from wind effects. Edit - wrapping most of the pipe would result in one downside , backing off into a corner the surface will remain hotter for longer, this may affect off corner acceleration helped by lower wall temp generated by heat loss from radiation."
