That new shock appears to be for a linkage type rear suspension MX bike, short travel and stiff spring.. Yeah, it's not the sort of thing that I really thought that I should use. Some time ago I was watching vids of my scoot vs racers and noticed that mine extends the shock back up as I take off and racers that launch well have little movement. I thought if I put something very firm on there that didn't sag much, that maybe it would improve launches. The idea was to go stiff, but not as bad as a solid steel so I could use it. I think it's very near a solid bar. Went a little overboard. Regardless, it's not doing what I hoped AFAICT. Currently considering taking T2 to a 9/11 ride on the Ocean City boardwalk. $10 donation to enter and there's a memorial service at the end. It's basically hundreds of Harleys and little else from anything I've seen in the past. I'd like to ride the boardwalk and I'm happy to be the one totally different thing there. Problems are; it's a drawn out event with registration and lining up starting 2.5 hours before riding the boardwalk. It's a 9/11 memorial, so I don't know if it's mostly Harleys because of some patriotic thing (as if their stuff isn't made in China now too) or if that's just because Harleys are everywhere. In addition, I see the Harleys revving and stuff... but maybe there's a limit on a memorial parade and you can't put me at 10MPH in front of crowds on the boardwalk (or all alone for that matter) and think I'm not gonna hop and rev it. I don't mind pissing people off in general TBH, but I don't want to be disrespectful to a 9/11 ride and I know that I don't just creep around and slow roll. Could be that no one cares or they're up for it, IDK. Plus, I don't know how long before OCPD intervenes when some jackass is playing on the boardwalk. I'd really like to ride the boardwalk and this is the only event that lets bikes do that. Could take the TMAX so I can't do anything but rev like the Harleys I guess, but I'd have more fun being on the small scoot that's nothing like anything else around. I'm probably gonna pass. Don't wanna spend a couple of hours waiting just to get booted out immediately and acting like I have good sense would only be an act and can only last so long. lol I grew up going to ocean city a few times each summer and still go occasionally and I am so surprised you are aren’t regularly shaken down by the fuzz down there who are usually just Salisbury students on a Summer power trip. Maybe you’re just really disciplined at keeping it below 40 on ocean highway but with ORV tags on T2 and not full MC tags, I’m just baffled LOL.

Maybe you’re just really disciplined at keeping it below 40 on ocean highway but with ORV tags on T2 and not full MC tags, I’m just baffled LOL. I don't really speed around. If I run it up a little, I slow right down. The strip is one big stretch of intersections and entrances/exits essentially and all of them are full of tourists. Not a good place to ride fast. I learned real quick not to take congested stopped intersections for granted too. People will let someone through and you don't wanna be going even the speed limit when they magically appear in your lane so I slow down for that stuff. I'll get into it and/or get the wheel up and other scoots better watchout if I see 'em... but I'm not actually trying to wind up under a car. TBH, and I hate to jinx myself, but I've been surprised as well. They pull over rentals all of the time. Those things can't go that fast. They do ridiculous things like jumping on and off of sidewalks and burnouts and trying to do wheelies and stoppies and just anything that sounds fun to what are usually teen-20s dudes in a group. Even I quit doing burnouts for the most part because I don't want to be sitting in a cloud of tire smoke waiting for police to see me. In a car show vid from last year a trooper told Ryan and I to "STOP!" when we were hopping around right in front of him. I got the wheel up pretty good before he said it. My only guess is that they don't take scoots that seriously in general and maybe actually wearing riding gear helps. My sport bike pal got pulled over right in front of a school in another area and got a warning. The cop told him that he was glad to see someone wearing gear... so maybe that matters to at least some? Bicycles will ride right past cops with a wheel up for a long time and I haven't seen them get pulled over... and scoots wind up lumped in with bicycles around here... but then also with motos/autos... so it gets a bit weird and it's hard to know what anyone thinks about it.

I didn't wind up going to the Memorial Ride on the boardwalk. Figured it's better use of my time to get other things done.
My runs the other day averaged 10.16 in the 1/8. Prior good tune average was 9.86. RPM was averaging between 12,958 to 13,124 from 30-60MPH, while the previous best results kept average RPM between 13,245 to 13,500.
I switched from 1mm of shimming to 0.8mm for a belt with roughly 0.2mm of wear while doing earlier testing. I tried going back to 1mm to see if that got RPM up any. I averaged 10.13 with RPM between 12,915 to 13,175. Essentially no change there, but it seems to like it better. The road was wet and I still averaged a 2.29 60ft with roll in vs 2.35 with some of those runs being very quick to WOT.
I swapped from 5.25g to 5g. I averaged 10.17. So 10.13, 10.16 and 10.17. Not getting very far here. This time 30-60MPH averages were from 13,698 to 13,873. Now too high, so I'm sort of dancing around the sweet spot.
I have inserts to do 5 and 5.5g so I may have to make up a few 5.25g inserts and try to hit it in the middle.

I made up 3 5.25g sliders and mixed those with 5g to average 5.13g. Naturally, it didn't go as data seemed to say it should...
5.25g = 12,915 - 13,175RPM = 10.13 1/8 5.13g = 13,623 - 13,813RPM = 10.05 1/8 5.00g = 13,698 - 13,873RPM = 10.17 1/8
It knocked off another tenth roughly, but RPM barely changed. If you averaged out RPM from 5 and 5.25g, you'd think you'd get 13,306 - 13,524. That would be about perfect based on best results. Instead, I go halfway and barely change RPM from where it was a 5.25g.
I can get into it quick and it's not getting the wheel up off the line so I think it's slipping. At this point, I'm prob gonna call it good enough to play with Harleys. Maybe I could swap in a new belt and get more grip, but since the belt still has life in it I kinda wanna use it and save a little cash there. I could try to make 5.2g or something, but less than 1/8 gram tuning is getting a bit too precise for screwing around on the street. Another option may be to go back to 0.8mm of shimming (from 1mm) again, but my 60fts averaged 2.29 so it's moving out well.
On paper I know it seems too slow to even play with Harleys, but I've done it before and I've seen some of them running 7 second 1/8 miles at high trap speeds with 60fts similar to what I'm doing. That's them at the track trying to drag race. Not all of them... some do way quicker 60ft than I ever will. Now get one at a red light that thinks the scoot revving is a joke and their old lady is on the back and they don't ever do actual drag racing, plus I'm quitting around 40-50 anyway... then suddenly it's not so easy. Now imagine Ryan there too, who's quicker/faster than I am. 😁
I am thinking about using a BR9EG plug for the show. I use BR10EG all of the time now. It's just a little hotter than the Denso that Malossi recommends. I was thinking maybe the 9 because most of the day is creeping around town where it's super rich. Generally just enough throttle to hop the wheel up regularly, a few seconds of WOT passing people, and less than 10 seconds of WOT if anyone wants to play from a stop. I'm not gonna be rolling down the strip at 80. I normally change the plug right before because it may foul one otherwise with all of the low throttle. Seems like it should be fine with a 9 series vs 10, as long as I don't forget to take it out when I go back to normal riding after Bikefest. 🤷♂️ If anyone thinks that's a terrible idea LMK.

If there is a tool or sensor to quickly pick up detonation or pre-ignition (not sure which one is induced by a too hot plug) you could adopt that and run a hot plug permanently. Its would be a nice addition to the bike anyway especially if you even want to venture into diy timing curves.

Since you know it runs rich at low part throttle then the hotter plug should be fine.
And yep, the street is the greatest equalizer in stop light drag racing. Will die laughing when you start carrying vht in a small squeeze bottle, waiting for the red light and you are prepping your launch pad 😆 🤣

I got this comment on the vid where I was port matching and smoothing out the RC1 cases during initial assembly :
"All stock banshee are weak and slow. If you think putting pipes on them makes them fast they don't. The porting, head work and airbox mod is the RPM killer with banshees. Deliberately de-tuned to be sold in the USA. Guys like me know exactly what to do about this. Eat my dust."
No vids on his channel. No, there was no prior conversation.
I refrained from calling him a turd with mostly mouth and ego, but I almost hit send before thinking better of it. lol I have much more respect for the folks that want to help everyone be faster.

Yeah we all know putting a performance pipe on a two stroke will never work.

I've made it into a few vids from Endless Summer Cruisin'. This one made me laugh as the dude filmed me and then said "What the hell is that?". 6:46 if it doesn't start at the right spot for you.

You should come up with a snappy comment to leave for him LoL "That's a bad ass 2 stroke scooter"

Someone caught me lined up with an old big tire van and a modified Trans Am. I left them when it turned green, but you just hear me in the background because the person filming was turning around. youtu.be/zTpNL_gn56A?si=_t-DDi4AXPU2E81W&t=1100

I guess my next attempt at more performance will be a big Polini 34mm PWK carburetor. I saw a Stage6 bell mouth/70mm air filter adapter and figured I’d try that. Turns out it’s for smaller PWKs and too small to fit over this one. When taking the carb apart for some work, the bowl was tough to remove and I found this bent tube. I thought it was a flaw so I texted Ryan and he said his is like that too, but should go on with a little finesse. Mine required forcing to try to put it on so I bent it just slightly and now it goes on alright. I have put the carb in the lathe and cut the lip at the edge off and just skimmed the filter mounting area to turn the cast part into something a little more concentric. I cut the inside diameter of the adapter and a bit off the back so it would fit. Then the ID of the bell mouth but was too small and had to be cut and blended. All of the cutting pit the set screws right on the edge, so I had to drill and tap for new set screws. I don’t think the bell mouth will accomplish much, but I ordered a 70mm filter so I needed it to fit or would have to return the filter and get another. Now I hope the filter isn’t too big to fit on the scoot. I haven’t done any installation yet, but here’s the 34mm PWK beside the 28mm VHST. I have already swapped the jetting and needle to specs from ryan_ott because it’s the same carb that he uses. That should save me a lot of time.

It makes sense to use a similar carb to Ryan. It's nice to be able to compare notes. I guess the internet will be happy now you have a bigger carb? 🙈

I guess the internet will be happy now you have a bigger carb? 🙈 Let's hope so. lol I'm truly curious if there will be any difference as I've always been happy with carbs on the small side of suggestions and the only flat slide I've used is the Lectron. I used an OKO as the first carb that I ever put on my first Triton, but didn't like it. To be fair, it was too big for my setup (though part of a full performance package that I bought) and I wasn't very good with carbs at that point so I don't count that. IIRC it was a 28mm for a sport 70cc setup.

I think you'll have much better luck with it now on this setup too, If I was to be a betting man I would say your carb troubles might just have ended...
(let us pray) 🙏
