I just went through and watch I believe around 15 videos and I hit subscribe after number 1. I love your videos I have always wanted to have a fast scooter but never really knew where or what parts to buy. With all the videos you have now I have trouble choosing which scooter I want to buy and put all my money into haha. Anyway great videos man keep it up.

[@RollingWrench]

Sweeeeet! Thanks for watching:-)

[@matari7183]

Your videos are great, thank you so much. I wish your camera didn't move so much and be a little more steady. I have learn so much just from watching your videos. Very well explained. Always looking forward to see them. Keep posting

Excited for my used c3

[@jeffmullinix7916]

I use a cordless drill in seating valves . It's fast and simple . But be careful . Not to much . I dont use course lapping compound .

[@kaostheory2940]

Instead of using a piece of hose to lap your valves you can use that white poster tack the stuff that you use so you don't put holes in your walls and a small wooden dowel pencil chopstick it makes it a lot easier and you can put pressure on the valve itself

[@RollingWrench]

That’s a great idea! I’ll try that next time :-)

[@kaostheory2940]

Rolling Wrench yeah I thought you'd like that idea I did it a lot on my pit bikes and stuff like that makes it easier and you get a good even lap on the valve

I love your videos! I have a 2007 C3 I bought new and its got over 20k on it.I let it sit for a few years because I was working too far away to use in my daily commute.Anyways I decided since I am a Welder and have an addiction to turbochargers I should try turbocharging my C3 and get more speed out of it.Im using a Garrett GT0632SZ no intercooler and a bigger injector and will be buying your tuner to dial it in.Near the sparkplug on the head there is a 6mm screw for check oil pressure.My first question is: Are there any other places to hook up a oil feed line to the turbo to get good oil pressure?I have a modified dipstick tapped with hose barb for oil return but also second question: Is the a full pressure lube system that I can even do this with? ALSO A 3RD QUESTION: Do you know what the stock fuel injector is rated at in CC's?

[@hybridorbital85]

I was told the stock head wouldn't work with the 75cc cylinder due to water jacket. Where did you get the cam? What does this bbk and cam cost?

[@RollingWrench]

That is true, you can’t use the stock head. I found out the hard way. Follow up video coming this summer. Cam was purchased in Taiwan. Here is the kit you neeed: www.rollingwrenchdenver.com/products/stage-3-performance-kit-yamaha-zuma-50f-vino-4t-c3

[@reinertalens3651]

Hello. Do you have racing cam for sale ?

[@madblunted]

Don’t they make small valve lapping suction cups?

[@RollingWrench]

Maybe??? A piece of small hose works just as good :-)

[@jeffreygibson5071]

Where did you get the tuner from?

[@RollingWrench]

It’s our own custom tuner, we have them on our website
