Ahhh.. now I know what Moofus meant when he said they use a mix of 2T and 4T parts on the stator. Thanks Brent! That link may have just saved me $100 in the future!

If you have a large taper 2t flywheel and stator from a parts motor with the right plug on it you can swap it all over to the adly but you will need to find a 3 bolt atv fan from a Polaris and get rid of the weird adly stuff. Standard scooter fan is short and atv is taller but the adly fan is 4 bolt Sent from my SPH-L720 using proboards |

I pulled an all nighter last night since I had the day off work today.
I watched Brent's crank videos (that sounds bad lol) about 4 times over and headed to Walmart to get a three pack of "Electronics Duster". After aborting at least three times during the process of getting the bearings installed and getting the crank set I finally got er done. Got scared multiple times that I had things stuck halfway on. Not as easy as it looks! Glad I went with the three pack of freeze spray because I used two full cans.
Nearing 5am I was running out of steam and realized this E-ton crank wouldn't work with the Adly stator and flywheel... seriously, what would I do without the help of everybody on this forum?! Luckily, I had just gotten edumacated on this subject and switched everything over to the Zip stator. I'll use the Turbofan for now and order a proper 90cc (three bolt) fan.
Now I'm back to where I was yesterday- ready to hang this 90cc! Funny- I swapped the 49cc motor into my scoot yesterday and only used it for one quick ride to the post office. Now I'm ready to try again again for some 90cc fun!
....There goes a TaoTao down my road.... wanna race? muwahahahahaha

This is the "freeze spray" I used for the crank bearings/crank install. I got them in a 3-pack at Walmart for around $11. The cans obviously aren't labeled as freeze spray, but they're basically the same thing. Just shake, tip upside down, and release -65 degree fury! I used a combination of the oven/freezer/heat gun/freeze spray method. I wanted to get the install done without waiting overnight with parts in the freezer and the electronics spray was capable of getting the parts much colder too. After a couple of aborts, the bearings needed to be re-frozen as they'd quickly absorbed heat and warmed up. Everything came together in the end with a minimum of abuse on the crank so I'm hoping for the best as I don't have the cool crank truing gauge yet. I've seen them at Harbor Freight and I may just pick one up next time I'm there.  |

IT'S ALIVE!!!
I got the 90cc all squared away and mounted back in the scoot. I meticulously put locktite on every bolt and squared away every wire neatly in preparation of keeping this motor in permanently from here on out. As I winced during first start-up attempt waiting for some kind of major dissapointment- again- she fired right up! Even sat there and idled nicely! Sounds nice and smooth. Yeeha!
After a quick ride to test her out it's obvious I have lots of tuning to do both carb and CVT. I have the stock vari in for now with e-start as I was anticipating it being a bear to start up...
I only hit 45 mph at 6k rpms, but the belt is way down in the clutch and I wasn't expecting much... she's purring like a kitten now and I can't wait to get everything dialed in!

These were 17 pages of pure pleasure and learning for me and I look forward to read more of the tuning part. Gratz on your swap, not everyone would attempt something like that.
Especially while wearing flip-flops.  |

Did you know if you mix acetone with dry ice you'll get extremely close to the equivalent of liquid nitrogen. My father showed me this when I was in grade school. He grabbed a frog out of the pond in our front yard dropped it in pulled it out and hit with a hammer & it shattered like glass. Then it defrosted in about 60 second and you can use your own imagination as to what kind of mess it was. Food for thought if you want something frozen super quick. Oh and if you do this make damn sure you're wearing insulated rubber gloves. I work with Liquid Nitrogen and even Liquid Helium all day long at my job. Liquid Nitrogen is somewhere around -195 F and evaporates really fast in ambient temps. But boy does it make for great fog when you pour a dewar of it outside on black asphalt in the Florida heat. No, we don't stick frogs in it though. But sometimes we submerge candy bars in it for 30 seconds and make fun frozen snacks. This is what happens when nerds get bored. |

Haha fellas the joys of instant freeze! Clank, you're like a mad scientist with a beaker in one hand and welder in the other lol. I used to work with dry ice when I was a "mixing tech" at L&L Products in MI. We had all kinds of fun with it blowing up pop (yes pop! not "soda"!) bottles etc. I also enjoyed many a instant frozen snickers  I wasted the third can of freeze spray with my 11 year old daughter. We froze a banana, a piece of cheese, and some old easter peeps! lol it was a much better use of the third can instead of freezing boring ol' scooter parts hehe. P.S. as a kid we also had much fun with "the works" toilet bowl cleaner or even sno-bowl and pop bottles... I won't give the method here, but for all the kiddies out there- don't try it at home! |

Brent, once again sir, you have hit the nail on the head! I put the new off brand belt in. After maybe 50 miles the belt has already started to de-laminate in one spot. It also doesn't seem long enough... Don't know if the stock Bando that was in there was just stretched out or what, but it's at least an inch longer than the china belt which sits low in the clutch even after getting my modded Hoca vari on and dialed in with spacers. So I'm using the Bando and I'll just keep this China belt under the seat for emergencies. |

Happy Monday fellas! I started writing an update to this build thread last night and it went something like this: "Dear scooter diary; I don't know what more to do with this 90cc motor as I've been tuning on it literally all weekend, yet, my 49cc motor still outperforms it..." kinda sad huh? However- I have great news! As of my ride into work this morning, my update now reads like this: "Woohoo! Yeeha! Finally! This baby rips! She nearly bucked me off the seat at takeoff and the scoot speedo reads 65 MPH top speed! I'm sure that translates into more like 55 actual MPH.. will GPS on my trip home for lunch. After tuning and tuning all weekend I finally had to accept the fact that my compression tester is not reading incorrectly -90psi tops. But why? She's got new crank,bearings,seals,cylinder,piston,gaskets, etc. Etc... WTF only 90psi!!?? Well, in the end, I did two things and I'm not quite sure which one it was that solved my problem...
#1: I laid on my back on the garage floor and literally went over every single mm of the case seam and cylinder base... nothing- no leaks- everything is sealed up meticulously with Permatex ultra grey- the good kind, the Moto1 stuff that says its fuel resistant and can be used as head gasket sealer, exhaust seal etc... wait... I see.. a teeny tiny little drool of oil coming from the case seam- just under the starter motor. Could this be it? Could this be the cause of all my 90cc woes? I didn't do a leak check as I don't have a 2T leak tester assembled yet. I was very careful to seal everything real good. Especially the intake as I always read they are a pain to seal. Hmm... I scuffed the area up real well and mixed up some steel putty and sealed the area..
#2: While waiting for the steel epoxy to set up I checked my squish clearance... too big to even squish the solder! Another hmm... at this point I am getting desperate-and it's getting late- after midnight Sunday night. I need to figure out something fast or enjoy a 37 MPH ride to work in the morning- blah. So I did something desperate- wish I would've gotten a pic so you can see... I went to that beat up wasted 49cc squish head you've seen a few pages back! Desperate times call for desperate measures lol. So I did a 10 minute sloppy "retool" of it, widened the squish band out to as close to 50mm as I could... it looks really bad haha. Smoothed it out with a quick spit of saliva and 1000 grit sandpaper and threw it on... 220 psi! Holy high compression Batman! So I pulled it back off and relieved it of some more aluminum. 190 psi now. I added- drumroll please... another head gasket. A 49cc one that I trimmed out with tin snips and annealed with the propane torch in hopes of getting it softened up enough to seal... copper spray between the layers in there too. I left it at that. Started it up for a quick second to confirm I had a ride to work in the morning- it idled way higher now. That's where she's at; no compression check and retorque after heating up. I rode it to work like that and just crossed my fingers I didn't hear any detonation... add to that the fact that I left off with an 80 main jet... I think I liked the 85 the best- I put the snorkel in to richen it up and took a gamble on riding it 5 miles with zero test run. Flippin screaming demon I tell ya! 90cc power baaabbby!
Sorry this entry is probably hard to read. I tapped this all out on my phone- at work hehehe....

Glad you got it back in and running better! No engine will perform without the right components and tune no matter the size. So many are fooled by displacement alone when a smaller engine in a better state of tune will out perform it. On that note, it sounds like your on the right path now tho! a leak down tester is worth its weight in the 2T tuner world! Its a must for me. Only way i can guarantee its sealed up tights from crank to intake! If i do end up with tuning trouble i can rest assure its not a primary comp or case leak. Sometimes a case leak will form out of nowhere but they become pretty obvious the more you tune. Sometime a case leak can be tuned around with richer fuel settings if the leak is consistent. Reading your thread i know you have the skill to make a very useful nice little tester that will help you out years to come in the 2T building world Nothing like the feeling of more power under the scoot!!!

Congrats man, I'd give a kidney to get 67mph out of mine!
Back off dammit! I NEED MY KIDNEYS!
This does make me scared though to attempt the BBK and such on my own though.... I'd lose my mind having to buy more tools and not having my own garage. Ugh. But I'll keep this thread in mind, leaks... leaks..

Thanks fellas! I am soooo happy I finally got this thing ripping like I knew it could. It's a bone stock 90cc cylinder and the cases are untouched as far as trenching etc. That means I have more to look forward to in the future! 103cc, 54mm big big bore, case trenching, big fat carb, mean ass Peace Pipe etc.! I already had a bit of an "incident" with it hehe. While firing it up at work to come home for lunch, I was d!(king around and goosed it coming up the handicap ramp leading into my Mtc. shop. The front tire came off the ground and I got a handful of throttle! lol it was all I could do to get her under control before going into the back wall of the maintenance shop! haha I'm pretty sure nobody saw me nearly crash there so no blood no foul. I love this scoot! |
