Why so big?

It all depends on the size of the wheel. They have TWO long case motors to accomadate the 16" wheel scoots. Alleyoop That I could understand I suppose..but this has 120/70-12 wheels. So maybe it is one of their 90cc Long Case engines with a 50cc top end?  So let me guess..special CVT and special clutch as well. But the 70 BBK will fit..will it not? I wanna figure out where the power that high comes from on a stock normally aspirated 50cc bore. Must be the port timing?? So the 70 BBK may not produce more power due to its timing..or will probably produce the same merely due to the larger bore size. All I know..only faster production 50cc Scoot I have ridden is the Aprilla SR50 with Ditch engine...this Adly...and then just below them..my old Bennelli X50 Andretti model. |

Why so big? Getting ready to buy an Adly Thunderbike 50 from my ex boss..who I was a Scoot mechanic for. It has 470 original miles.  Fastest stock 50cc 2T I have ever ridden. Which confuses me since it's Her Chee made...but still your standard Minarelli engine. 55+mph out of the box by only adding a Technigas pipe. Rest is stock. So I assume the Minarelli 70 BBK's should really turn the power on. My question is why is the belt so big?? Long Case Minarelli's use a 788 belt...the spare he is tossing in is 878 and what the lil booklet calls for. So why would the Her Chee Long Case engine use a longer belt than it's twin...the Long Case Minarelli?  |

16 on the clutch input shaft? Odd...what are the teeth count for the other gears. This is from a long case with 12" tires correct?..  |

DX Anti seize is great for CVT and Clutch nuts...sure beats eating up the crank or clutch input shaft threads from the impact wrench.

You might get some temporary help by installing lighter rollers in your variator. I found with my Xingyue 150 that 13-gram rollers act almost like your gear situation, but 12-gram rollers were way too light, running the engine up to near 6K rpm at only 45 mph. With some luck, you might find lighter rollers could be ideal with your present gears. Worth a try for sure! Sincerely, Leo in Texas Leo..tx..tried that..went as low as 5 gram even..vice the 8's that were in it....same thing. The gears are just insanely high..the 5's gave slight better take off...but engine rpm's still could not climb. The gears he installed come out to a 30% increase on my PC 's calculator!  |

hank is a guest now?.. well that sux...what did I miss?. Anyway he is right...2T's are quicker off the line with higher top speed. Just sold one and getting ready to buy a Adly. Bad side of 2T's is as prodigit said above....my gas mileage was less  Also they are so fun to hop up..you just seem to inherently keep installing performance parts...taking a test ride...come back grinning....and buy more Hi Po parts....until yer broke... ;D Piston rings and cranks also wear faster than a 4T.. But man are they fun... |

Desperately seeking stock 139QMG long case gears!! Bought a used 2012 4T Scoot. Guy put super tall short case gears in this long case engine. I am sure the gears would even be too much for the 10" tires..cause with these 12" tires it barely takes off...clutch slips for the first 25-30 feet since the ratio is so high. It feels like starting your car out in 2nd or 3rd gear.Can only rev up to 5,500 barely hitting 40mph unless going down a nice steep hill. Uphill it drops to 30 or less as the clutch slips and really heats up. HELP!!! I want stock long case gears...this is really straining my crank and clutch... |

DX I desperately need the clutch input shaft as it has the stock long case primary gear I need. Actually I need all the gears in the long case...cause the guy I got this new Scoot from put in short case 'Over the top' super high ratio gears. While that may be borderline ok for a short case with lil 10" wheels...you almost have push off by foot with those high gears in a long case with high profile 12" tires. That is the reason I can only reach about 40...the engine is loaded down wayyyy too much. Not sure what he was thinking. The 100cc BBK is only truly 83cc...and after a few calculations it would take a true 125cc QMI engine to get up to redline...and the speed would be 60-62mph....but even a true 125cc QMI engine I doubt could ever hit that speed even...
