Seriously who dislikes videos that are intended to help you out ?

Cameron, I am 41 with 3 kids and about 5 bikes (2 and 4 strokes) at any given time. Please provide more trouble shooting content. You are a great teacher. You teach how to think through the problem logically. And your videography compliments your basic instructios for a simpleton like myself and I assume many others. This will expand your subscriptions. May I also suggest a video on 4 stroke valve adjustment? Thank you for your content!

I just got myself a 98 cr125 it was in rough shape when I got it. It was used and abused by the last owner, I just wanted to say a lot of your videos helped me get it looking and running great! Keep it up brother great content in all your videos

..would have laughed it if it was the connection rod bearings... ;)
first thing to learn as an dirtbiker..always keep an aditional sparkplug ready!
well done!
love your vids..
greetings from germany

Keep up the videos I’m learning a lot from you so far

Really liked your 4-stroke (Yamaha) video on think that you left a bit out here. Might still be a little will bow to your knowledge on jetting. On 4-stroke the idle mixture screw controls fuel....so going out richens/in two-stroke it controls the air....going in richens/out leans. I know you know but some of your viewers might not. You are a super good teacher....others can really learn from you. How goes the health? Praying for you. Tom

Just watched!!! Thank you for the advice! Mine ended up being the needle on notch too rich! Leaned it up one notch and was perfect!

Best video I've found finally fixed my 2007 cr 125 absolute gem of a bike thank you.

[ryanarnettrealestateagent]

Your videos are the most informative videos on YouTube. I'm learning a lot about 2strokes, as I grew up riding 4 strokes. Keep up the good work brother!

Doing a project bike and can't figure out why it's bogging I cleaned everything and checked everything and got to my airbox and I'm missing a screw and part of the boot is clearly coming off the box, hopefully that's it ! Thank you so much man your videos have helped and continued to help me work on bikes

I have an 07 yz 250 that still has the stock piston, rings, crank, and plug. Put 100 miles on it last weekend and still runs great.

[aaronbright]

When a two stroke doesn’t rev out it is because something is causing it to be fat. So the plugged peacock and vet hose would not apply here. Crank seals would also make it lean. Being lean would make it high idle.

Info was great! Everything you mentioned is easily overlooked. The only thing I do not recall you mentioning is the carb getting gummed up from sitting, considering the poor quality of pump fuel at times. Ethanol can do nasty things when left to sit for extended periods of time. Just another easy item to check before I would consider tearing into the engine itself.

[trustnuffin]

Excellent video once again : )
Is it possible to have much success at all by cleaning the head of the plug with a small gas torch or have you found that to be pretty much a waste of time ?
Thanks

[NicoVisions]

Hey cheers for the video! What are the main symptoms of a leaking crank seal?

[joshmx]

Sometimes that insulator inside the plug will crack and it will look ok but will be sparking up inside the plug and not down at the electrode tip. I think it happens if the plug is screaming hot and then gets a dab of oil or fuel on it and the porcelain cant handle the thermal difference.
