@@user-vl2lz9fk9y cool. Hope it gets you speed.

@flintstone4208 chinese speedos are generally way off. Use your phone to do a speed check. If it is a digital speedo, you can usually calibrate it and there are good youtube how to videos. When my wife's real vespa says 72mph and the GPS says 64mph.

also does a 842 belt really make that much of a difference?

@speedymillz6675 watch my CVT kits are a scam video. Your next gear up step is a 115mm variator. Test that then add a 842 belt and test that. With a 150, you may or may not be Faster with both and have to go back to the 835 belt. Run that until you get a big bore prob. You need a lot of power to make a rear end gear set give you more speed. Personally I liked the bike better without the gear up kit and doing 68mph as it was a lot quicker to get there.

I have no idea. Have to know what RPM you are currently running and then know what RPM you want to be at. From there you can figure out the percent of increase you need.

@@GhettoWrench I have 30mm Carb and I keep the RPM at 1900 - 2000 since that everyone recommends to keep it at that number.

@spikonn I mean at full speed. What RPM? If you are not above 9000 RPM I doubt the gear up kit will make you faster

@@spikonn This one prob explains it better: kzfaq.info/get/bejne/etlhe6uZ3pObkXk.htmlsi=ob3eVfpzACJvHTM1

I would not think any. No clue what's in there stock. Are you hitting redline? 9500 RPM. If so, do you already have a larger variator? That is the first gear up mod I would try.

You have geared that thing very tall with the gear kit and large variator. Imagine being on the highest gear on your bicycle. Your legs are not strong enough to pedal and go fast. I would imagine your RPMs are low (6000 to 7000) as you bike is struggling with that high gear. What have you done to the motor power wise to push that that high gearing? I have a 171 kit, Cam and 28mm PWK. I also used the (smallest amount) gear up kit.

@@GhettoWrench I have the 150cc upgrade from cajun maddogs 26mm carburetor ,ncy ignition coil ,ncy cdi box that's it besides the Trans and cvt

@earlisfayette9061 so the NCY CDI is actually slower than the stock. I have videos proving that. The coil makes no difference on power. We don't have enough compression mods to need a bigger or hotter spark so spark is spark. The 26mm carb is an upgrade, but to what? You need a reason to need more fuel. More displacement or more RPMs or cam etc. Do an electric fuel pump and re-tune your carb, and you will notice a big difference. You may try putting the stock CDI back on and seeing which one you like better also. What RPMs are you running wide open?

@@GhettoWrench 7000 rpm max

@@GhettoWrench I was planing to order the electronic fuel pump and pulse from rollingwrench and a afr gage and a 172 big bore kit with cam and slide carb

@@kaddymorgan1625 prob just lower RPM and better gas mileage. I am not a fan of the gear rear drives on maddogs. They are already geared up with their big wheels

Stock goes about 50mph. You can follow these videos and see what it takes to go faster. The free mods are probably the best. kzfaq.info/get/bejne/ar6TapiEzdTVc3k.htmlsi=Xj0yvy9Dta2KowoQ

😆😆

@dons.hacchh Taida T100 Cam and 14g rollers in a 115mm variator

​@@GhettoWrenchso I'm putting in a 15/37 gear it was a pain in the ass to figure out I asked a few that did gearing no response. So I just went with 15/37. 🤔🤔

@user-vl2lz9fk9y worth a try though.

This one, bit I hear it is not working for download now play.google.com/store/apps/details?id=com.milejko.dragracer

No idea why this was recommended but i pissed myself at the start THIS IS GONNA GET SERIOUS hahahaha yea on fucking china 150 lol

@BIGSMOKE-bl2lq ya these things are slow AF. My wife's moped is still faster. LOL

@tedowen409 Yea, it looks like it's for an older version of Android damn! Thanks though!

I want to know too

Not even. Look at other videos. Big Bore kit, Cam, 28mm PWK, big valve head etc .

Well gear down will give you torque and going up will give you speed, but only if you can currently hit redline. Every bike is going to be different. You would just have to try some. I have not tried gear changing a 50 yet

Called "Drag Racer" but the link is dead. Which is nice cause no ads.

Do a 150 swap

Don't ask 49cc scoot, or rolling wrench. IV seen a lot of videos on KZfaq.

My buddy just went back to stock gears and went faster too. I have the very mildest gear up kit tho... only 14%. He had one of those more normal 20+% ones.

LMAO. I actually have a pretty solid background in built liter race bikes. You are correct tho. It's Def a moped.. just with the plastics off. Most my posts say scooter. I'm old and prob got confused.
