Greg, you do a great job with all your videos.I am almost 63 years old, and have worked on Karts since I was 9 years old, and only had older guys with little patience for kids to show me anything on "How to". These fault finders commenting are silly as all get out.There is so much knowledge online! They have no idea how lucky they are that people like you take the time to show them anything! I progressed to building dirt track late models, and now make parts for the Nascar world. I watched your video on the billet flywheel, cam, valve springs, and Mikuni VM-22 for guidance to build a Predator Hemi for my 8 year old Grand Daughters Jr. dragster. It ran almost dead on her required 11.90 index, her first ever pass down the track, on gasoline. Engine builders are charging $2000 for an alcohol engine to do that! A little jet and gearing tweaking and I think it could run low 10s ( when she has more seat time!). Keep up the good work! Proverbs 1:7

I don't even have a 670 but enjoyed watching because This really is an invaluable video for those planning a 670 build, rebuild or even just repairs down the road. Anybody with common sense and basic tools (&at least basic mech abilities) can confidently at very least open up the top end, remove, replace and repair or upgrade various components with little worries with this step by step walk through.. thanks for your time and effort

I didnt even realize this was for go karts until the comments lol I'm into this for it being my mud motor

Cameras on smartphones made it so much easier to do things like this. I remember when I had to write down the order of every part I removed and the bolt lengths so it would all go back together without having a mysterious bolt or 5 left at the end. Great job, excellent tutorial. Two thumbs up.

[michaellinner]

I commend your efforts to teach the younger kids out there. I wish there had been someone like you when I was a kid.

[stephensellers]

Man it's hard to believe you all blown up like you have own business I'm so happy for y'all y'all are good people and you deserve it

[tebeardenkahboom]

It would be nice to see a stock configuration performance and then a modified configuration performance to see what kind of gsins you achieved

[LITEWRENCH]

This is the most clear, thorough, easy to follow u-tube video I’ve ever watched. This guy needs to stop working on engines and start training u-tubers.😂👍😂👍

[davidelo]

This was a really well done video ! One of the best on you tube ! Thank you for the hard work making it ! I really appreciate your time and effort !

[steblo]

Hi Greg, watched your videos for years and I've never seen a Chanel make so much progress in the quality of builds and in the quality of videos themselves, you are one of the most informative people I've come across while being entertaining the whole time, keep up the good work all of you at RBG!

Sweet build. Cars and cameras will be jealous

[ollilehtonen]

I love these engines so much. Sound so good with a cam and open pipes. And last forever too. I really want one.

Years ago the guys at OCC built a chopper for a lawn mowing company. This motor mated to a five or six speed trans would be awesome on a bike. Great video guys, thanks for sharing.

[andrewstamberger]

WOW!!! I like the intro and I like that you show the tools needed in the bottom corner!

[williamlee]

They are not actually lifters they are cam followers but I know what you meant. You can actually take your smart telephone along with this video and completely disassemble this engine and completely assemble it back in running condition just using this video stopping and starting as you work. I don't know of any other video that allows you to do this. What a very concise and perfectly described video on how to teardown and reassemble this engine. Wonderful job. No needless chatter or comments just precise instructions. Perfect. I wish others would follow your lead on editing and finishing their videos.

[SportbikerNZ]

I really like your engine builds and I'm not even building anything. Your engine build vids almost make my mouth water over these engines. They're cheap engines, but that's half the fun.

Great build. Looking for and engine for my E/AB aircraft, original design was for a 1/2 VW. Just a tad but heavier but a lot more power.

[mercedesvan-doors]

That's a nice clean build and it sound sweeet. In the 80's and 90's I built and raced small capacity 4 stroke bikes and spent a lot of time tuning engines very like this one, for example a CB250k4 Honda revving to 14.5k. There's a lot of simple things that look like they would be effective in this type of engine, happy to pass on if you think it would help.

40 hp is pretty good. I put my 73 Harley Davidson Sportster XLH on a Dyno and it only had 45HP and that is with a 1000CC V Twin Ironhead engine.

[nojnoj]

Sir, you are a master mechanic. I would have to be reborn again to do what you just made look so Good job buddy, good job.
