OK, so finally after broken engine mounts and rain delays SuperEngine is through it's break-in period and I can provide some feedback for those interested and thinking about a SuperEngine. 1. You will be disappointed here because everyone (including me) evaluates "performance" by top speed, and this engine in this Retro scooter is powerful enough that I'm not very comfortable running the thing at a those kind of speeds. Maybe soon I will, but until now I haven't. Sorry. (Riding this scooter at 80mph was never my goal anyway, so ...) 2. If you don't want to bother reading further: my scooter, with SuperEngine, is damned near P E R F E C T.3. Some feedback on the changes other than the engine: - Gears: The scoot has a much lower final gear set. The OEM gearing was 13/40, or about the highest gearing you can get at 3.1. Now it has 16/36 - very low ratio of about 2.25. SuperEngine has plenty of torque to pull with this low ratio, and no doubt 16/36 or so is better for highest top speed ~~~ but i don't care about that since the scooter's suspension simply isn't safe much above 60 or 65. If I had it to do again I'd probably go up a notch to 16/37 (about a 2.3 ratio) just to move the power curve down a bit .... but it's too close to ideal already and will not bother.
- Clutch: Thanks to GEH the scoot has a full NCY clutch (bell, pulley, pad assembly, 1,500 Contra spring) instead of the OEM setup before. To be honest, I do not see much of a change. The OEM setup had long pads like the NCY; don't know what Contra was in it. And the NCY clutch is a VERY expensive mod. I'd suggest people NOT spend the money unless they really do feel slippage (I didn't).
- Tires: Figured out how to install slightly wider Michelin City Grip tires using a 6mm spacer between the final drive bearing and the wheel, moving the wheel slightly to the right and creating a bit more clearance between the tire and the variator-side of the engine casting. These tires are MUCH better; hopefully will give more mileage too. No noticeable downside to using the spacer.
- Variator: Again, thanks to GEH the scoot is now using a K&S variator instead of the Dr. Pulley one I had in there (which costs twice the price of the K&S). Sorry, but have not yet had time to mess around with weights and tune the variator (using 12gr Dr. P sliders) ... but the K&S, untuned, seems at least as good as the twice-as-expensive Dr. Pulley. Will have more info here when I get to tuning.
4. Performance As I said, this scooter is almost perfect now. It cruises at 70 to 75 ChinaMPH at half throttle or so. That doesn't mean top speed would be a ton higher - it might be I'm using close to the full carburetor at half throttle - don't know how much more remains. But WAY off WOT this thing just floats along, at 6Krpm or so, effortlessly. Oil temp has not once been higher than 175 deg. Where I was before, with the 60mm BBK engine, at WOT to hit 60 or 65, this thing now just flies. I LOVE it. Going up moderate to steep hills the scoot continues to accelerate to 60 or 65 ChinaMPH. Before, on the same hills, it would slow to under 50. It's wonderful! Off the line takeoff is fast but not a rocket sled at first. There seems to be a 1 second or so period of good pickup, after which the scooter suddenly just starts pulling and does not stop until at a scary fast (for this thing) speed. The prior engine, with the ultra-high ratio gears, didn't have this "pause" in takeoff and at times would pop the front wheel up (not safe on this thing). Not happening with the gears I not have and with SuperEngine. However, after 5 seconds or so SuperEngine would have passed (flown by) and would leave the prior engine in the dust. I was always (prior engine) able to keep up with cars off a red light (unless they were racing me) ~~~ now they are far behind. Again ... perfect. So, overall .... for what I'm looking for ... this thing is close to heaven. It's gone from something that, before, would be screaming to keep up with traffic to a scooter that just effortlessly flows, at moderate throttle and plenty of power to spare. Hills are no longer noticed. Of course, it's still a Retro scooter and is crappy at high speeds (especially with the barn door windshield) and for long distances. I use my Goldwing for that. But the Goldwing is a at 900+ pounds, and it' getting almost zero use now a days. SuperEngine wasn't cheap, but my oh my is it great! I remember when I posted about my engine temps being between 170-200 or maybe 180-200 degrees f . I got mauled by some , lol. Some thought I was nuts . my scoot with a bad oil pump was running around 270. One even posted that near 300 was OK . on very short runs "10 miles" , my temps were down near 150-160. Its nice to know these scoots run very low oil temps. |

Gates are the best belts you can buy . it sounds as if you have some other issue . I've had v- slides break and fall out before , but it was caused by bad tranny bearings. They were so bad that they were causing extra stress on the CVT causing the slides to break. I never had a gates belt break do to a missing v-slide.
You really need to remove the variator and clutch to inspect both.
For some reason you prob have belt slippage caused by a number of possible issues in the CVT or tranny , causing the belt to heat up and be torn apart.

I took my side cover off to inspect the starter new ncy starter clutch and it was in pieces !! many of the rollers fell out when I removed the starter gear, and I did have a groove wore into the part of the gear" were the rollers grab " . I replaced it with a new starter clutch " stock type " and all is good . I'll have to watch it just in case it happens again.

My little girl just got a wish from " make a wish " we will be going to Disney world in Florida , probably in February. They came to the house a few weeks ago to talk with us and see what Victoria wanted to do. She is six years old now and we all thought she would really enjoy Disney. We will be driving down . they pay for a rental , gas and hotel for the trip down and back , everything is paid for at Disney , free meals and around $1500 spending money . she has hypoplastic left heart syndrome .

When I was about 17 , many of us use to play release at night . for those who do not know what " release " is , its a game somewhat like hide n seek for older kids , lol. You have 2 teams of however many , one team hides and if you get caught , your taken back to base . if someone from your teams makes it to base without being caught , they yell " release ! " and everyone caught runs free and hides again. Anyway , a buddy was hiding on a 20 ft roof . when someone went up to get him he climbed to the peek and grabbed a branch from the tree that was pretty much right against the house . somehow he thought he would just swing down " 20 ft  " and get away . needless to say it turned out a little different . at some point he lost grip and landed on his wrist snapping both bones above his wrist . you probably could have heard him scream a mile away , lol. His arm was broken at about a 60 degree angle and the bones were nearly popping through the skin . one of the neighbors called 911 and before they put him into the ambulance the EMTs had to put his arm into an air cast. They had to pull on his wrist and put the bones in place enough so the aircast could hold it in place. Most of us had to walk away because of the screaming . to be honest he was always sort of a cry baby " not that I don't think it sucked and really hurt" but he sounded as of both of his legs were being ran through a wood chipper, lol. The point of this story is that a couple days after he got the cast off , he was jumping on a big trampoline and as he caught himself falling face first into the center of the trampoline , his wrist snapped again in the same place !! He ended up needing to have pins to hold everything in place so it would heal correctly . so just be careful and do everything you need to do to let your bones heal properly. |

As long as it only sits for a few months it will be fine to leave the fuel in the scoot and use something like stabil or seafoam . just make sure you run it for a few mins so it makes its way into the carb. Also I would keep the battery on a trickle charge all winter . you can also do as lain suggests , there is no problem with using his methods, its up to you at this point.

Those darn deer suck !! After I hit my first , my scoot was on its side running for about 20-30 seconds . this burned my oil pump up . was the scoot on the left or right side while it was running ? Right side for sure. You should be good then. The pump should not have ran dry if it was laying on its right side . |

U may end up having to use the 15 gram rollers . let us know how it turns out!! The k&s ran my rpms up unless I used heavier weights . Yeah, trying to figure that out. As you know, George, I had 9gr sliders in the Dr. Pepper variator with the 60mm BBK. But that was with 13/40 gearing, which is a 3.0 ratio, and that with little 10 inch wheels. So now I've got SuperEngine, 16/36 gearing (about a 2.25 ratio) and your K&S variator. Before putting the K&S on - with the Dr. Pepper and before the gear change - I started out with 12 gr sliders but they were too light. So, when I changed gears (still with the Dr. P) I put in 14 gr rollers. They were too heavy -- a lag at takeoff and RPMs never, ever above 6K So this past weekend I put the new clutch in and the K&S, with a new set of Dr. P 12gr sliders. Way better than the last stop - maybe perfect for me - but also maybe not optimized. RPMs get up to 7K but normally are in the 6,500 range. I dunno. Really - I dunno much about variator tuning and do not know if I should keep messing with it. Your thoughts? Are you able to break the 7000 rpm range on a straight shot or is 7000 max ? I never tried sliders in the k&s . if 7000 is max on a straight run , I would hold there since your not looking for a speed demon . hat is your mph at 7000 rpm an a straight run ? Did you mark belt climb ? I'd like to know the different from the Dr p and the k&s. |

I've been having an issue with my electric start. When I try to start up my scoot I get this high pitch noise sounding like a baby elephant bellowing. I can stick my socket into the fitting on the fan and rotate it past TDC (like an old Model A) and the starter will engage and then it turns over and starts. I need to get a new stator ( the voltage is low on one of my wires from it) so I figured if it is the starter clutch I can tackle that while I have that side open. i am trying to get everything straight because I'm going to use this scoot to get my motorcycle license and I need it in tip top shape to get past the road worthiness inspection before the road exam. Any help would be greatly appreciated. You may have the same issue I have ? The scoot is making. Almost a weird noise " not really a wining noise but almost like an elephant noise, lol. " it seems like the starter clutch is not grabing like it should. If I give the fan a boost the crank starts to turn but not like it should . with the starter in the crank is hard to turn by hand , but with it out it turns easy. I think in my case the starter clutch may have been stuck " engaged" and wore out the rollers in the starter clutch or wore a groove in the crankshaft !! I'll know 2mro |

If your scoot is stock , go with the 26mm over the stock 24mm .
