How to install a scooter gear set (final drive)

[@donbarcomb5913]

6:09 ……. from the back side, I’m just gonna TAP it!” (Grabs “BFH,” proceeds to swing, and beat drive gear like it owes him money!) Love the vids tho man! U don’t miss anything! Any question I have working on my “Scoot,” I don’t have to go searching for answers! U answer any questions! Plus, u show all kinds of little secret tricks I never knew about! Keep it going man! I know plenty of ppl who have spent THOUSANDS at local scooter repair shops, over real simple things, and all they gotta do is watch one of ur videos!

[@RollingWrench]

Thanks dude for the support! Anyone could do this stuff! Just need to know how :-)

[@Robvdh87]

Nice informational video. I would advise to always check (or preferablely change) the final drive gasket. Especially on older models because there's a big chance of leakage. Ask me how I found out 😉

[@LeVuUy]

What is the difference ratio between the original and the new gear?

[@AlbakrySalehuddin]

Need an opinion here, on my commute to work on my 2018 Yamaha NMax 155 its mostly highway speeds, should I go for a bigger front pulley or a smaller final drive dropping from 35 to 34 teeth. I can only do one at a time, which one will you do first? Thanks in advance.

[@robertorochamartinsrocha7041]

super video...i need to put another gear ratio on my suma 125i ... for velocity 🙂🙂🙂.. thanks man

[@andyb9994]

Thanks great videos and instructions. Very easy to follow.👍

[@jasperdomacena6491]

do they have a final drive set that has higher ratio? I'm gonna build a 150cc off road trail scooter and I need all the intial wheel torque i can get

[@ninoechavez1402]

Hi, is it normal for the gear oil to leak on that small hole/vent under the case just beside the drain bolt after replacing the gear oil? It started doing this after i replaced the oil.

[@heritagehillsecurity8778]

Thank you.

[@alexcalderon9021]

If I did your big boy bbk and changed the gears on my C3 .. what kind of performance can I expect? Top speed? I want this for city commuting...but I live in Socal, so I'd like to be able to do 50 mph fairly easy

[@RollingWrench]

It will do 50 but I would say 45 would be a cruise speed

[@YamahaCubed]

My C3 will do about 45mph top speed with 3 gram Dr. Pulley weights with the restriction washer BEHIND the variator. No big bore kit or special gearing.

[@williamhayesiii8031]

@@RollingWrench could you do one on a 2 stoke beammer

[@williamhayesiii8031]

@Tommy Dogs beamer ii is what I have is a fast bike on top and bottom its . Easy to rebuild if I ever have to the bike cost 1800 new I picked it up for a good price.

[@psychouki]

So it'll make the c3 hit 50mph but what do the rpms climb to when installed?? Is it safe to pull the throttle all the way back on these c3's and ride it like that or will it eventually kill the engine in time?? I just picked up a c3 today and I'm watching your videos to see what all I csn do to make it a little more peppy.

[@RollingWrench]

These motors are super reliable when upgraded. I haven’t had any issues. My C3 goes 67mph . This is the kit: www.rollingwrenchdenver.com/products/stage-3-performance-kit-yamaha-zuma-50f-vino-4t-c3?ToPasteboard

[@psychouki]

@@RollingWrench so no porting neccessary of these kits?? just bolt on??

[@vladyoftana8503]

Sir any recommendation of my gy6 QMK 171CC engine, i want gear set like 15/37 to gain some additional speed.. Where i can buy those kind of gearing on my gy6 qmk 171cc engine.?

[@shinos9917]

great video! I see your belt does't go all the way up (I noticed the groove of the belt on the variator). Is is because the sliders or rollers are too light or the contra spring too stiff?...or both? For sliders what weights did you use?

[@RollingWrench]

Thank you 🙏. It’s because the sander was installed before the mod. After I removed it, it would now go to the top. Check out my other video on free Yamaha c3 Performance mod.

[@gizmo1252000]

nice precise video ,thumbs up .

[@SteelRoninTT]

Is there an equivalent to this that would work with my 2009 Honda Scoopy (Metropolitan)?

[@RollingWrench]

Yes

[@SteelRoninTT]

@@RollingWrench Where can I find that please, I've been looking for so long!

[@Doc842]

you didn't show how if you remove that space or sometimes you have to add additional one behind the starter cup

[@Doc842]

sometimes with performance parts if you don't install that washer when you go to tighten the nut it'll just cinch down on the splines not the drive face

[@shawn2755]

Does anyone know of a gear up kit for a 2013 kymco super 8 2t, all the gear up kits I have found did not include the super 8 2 stroke only the 4 stroke

[@jaysonr123]

On your web site when looking up enuine Scooter Company Chinese scooters 49cc/50cc (QMB139 ENGINE) Taotao 50 Transmission / Cvt You have these gears listed as fitting Are they going to fit?? Or is it for only the scooters in this video?

[@farmboy694]

Just give it a little tap! Tap tap tap it in

[@gabrielflores4224]

what should I use if I dont have a press?

[@N8DE420]

How do you ride that there’s no seat or front wheel

[@thegooniverse495]

How much of a difference does just this make?

[@RollingWrench]

This mixed with a big bore kit is a giant upgrade. Like 67mph top speed

[@Cito_Fiytb_617]

Can I use the gears on the stock motor without bbk?

[@Bert439]

You would decrease performance, the stock motor does not rev high enough. Upgraded gears are meant for BBK builds.

[@JK-xq3qe]

I'm looking for performance gears for my kymco agility 50 4t. Will these work or is there another kind I have to get?

[@RollingWrench]

Those won’t work, but these will: www.rollingwrenchdenver.com/products/qmb139-transmission-gear-set-18-increase

[@trapp7763]

If I put 18/36 gears in a stock 150cc scooter, will I see any more top end speed?

[@buzzfeedright4154]

Tra vis yea but it would accelerate slow as all hell.

[@mrantone916]

Duuude i gotta change those primary gear bearings. 😖 Fudge.

[@conroybaptiste59]

What size was the bearing

[@sean7058]

How well does this do on steep hills

[@RollingWrench]

Terrible with the stock engine. Great with our 76cc big bore kit

[@monty81567]

Where can buy the center kickstand,that your using on that GY6 motor?

[@Tradeofjane]

It's actually a Minarelli motor. The stand is stock on a Yamaha C3/Zuma 50F/ Vino 4T.

[@mimo33437]

👍👍

omg please put that variator in the trash and place a new one
