In my older years I have taken up the hobby of building motorized bicycles and my current project is an in tank frame, shocks forward and back, with an 80cc ported racing motor and a 21mm pwk carb and have been chasing down tutorials left and right and as of date I have found this video to be one of the best. Very comprehensive, to the point, and quite informative. Thank you for your time and effort. Outlaw Dog

[@connorcrago597]

I just love how you explain everything in such depth, and how you change all of your personalized settings for your bike just to show what it acts and sounds like to help your viewers. Your a great dirt bike mechanic. But I think you should do more riding videos also at the track feel like that would be awesome!!

[@Studdfromhell]

Hey Cameron. I have been working on and riding Dirtbikes almost 37 years. You by far have one of the best positive attitudes around. Your teachings on jetting throughout the video is spot on. Lots of people.do not know the correct way to jet amd blow top ends left n right. It truly is more than just replacing pilot n main. The needle is extremely important along with the air screw verse knowing when you need to up size or down size the Pilot. Also worn slide and other small air leaks go without being recognized as a possibility of cause. BBBRRRRRAAAAAAPPPPPPP!! BRAPPP

[@orijinalgamesta9738]

Thank you for taking the time and effort to move the needle and give a running example. This is exactly what my kids new ktm 150 sounds like in the mid range. KTM support and dealership were ZERO help.

[@AuMechanic]

Good video. Couple of things to add, some comment refer to AF ratio of 14.7:1 That is the AF ratio that will hold and engine at a constant RPM, to accelerate requires a richer mixture. 2 strokes don't run at that AF ratio anyway, they require an even richer mixture at constant RPM to help cooling of the piston and lubrication, if you set a 2 stroke to same as a 4 stroke using an AF gauge or Lambda sensor you'll seize it in a heart beat. Also the idle mixture screw, there are 2 types, the one Cameron is adjusting is an air idle screw and screwing it in is richer, the other usually under the throat is a fuel idle screw that screws out for richer, more common on 4 strokes though. Both are tuned using the same principle he describes. If you need to run other than centre needle clip position it is indicating you need to change the nozzle size and or slide cutaway. In general jetting always set the Main jet first and work your way down to needle and then idle, a rich MJ will cause some over run of fuel and effect lower end jetting on a quick back off and re acceleration at corners.

[@sidecarbod1441]

I agree. people bang on about 14.7:1 as being a magical ratio, it has no place in any engine! It is just the ratio that you could burn a fairly standard petrol (gas) in a chemistry lab and have no free oxygen left or no unburnt petrol. Even in a 4 stroke you can run the ratio leaner than 14.7 under cruise conditions and you would run richer than this when the engine is under load. 12.8-13:1 being about right for WOT condition at high RPM. I doubt that a 2 stroke would ever want to run leaner than 13:1 under any condition.

[@allannortje6440]

Yes Sir, well done professional video on everything carbs for a 2 stroke, I live in a rural area in South Africa and can make a ton of money fixing 2 stroke bikes and this is like one of those videos that teaches you everything. Also I guess a rich mixture would indicate a wet spark plug when testing for spark too, it would be cool if we could learn everything there is about these bikes enriching our lives. I don't care if these videos are like 5 hours long we need all of them !!

[@francobazzi2576]

You should definitely start working on 4 strokes as well. Excellent video Cam!

[@wasabiemans]

Kris Thistle don't forget to check the oil fuel ratio, because consider that more oil, is actually leaner because there is less gas so take that into account

[@sparky_zap69]

TheNoobStevio it’s a 92 KX250, owners manual says 32:1 so I’ve been using amsoil at 32:1. So what should I be checking with that?

[@wasabiemans]

Kris Thistle no your fine it's just some people test the bikes with different ratios and it's acts as like a double factor if you get what I'm saying

Check your reeds and crank seals too

You can also buy or make, (if you have a metal lathe), a little spacer to go under your needle clip to move the needle only half the normal distance of a clip/groove move.

[@tylercurtis441]

its ok to be a little rich. infact most of them are factory slightly rich because well being a little bit rich wont hurt a thing. being a little lean will cause premature wear but better performance. like cam said BREAK IN a new top end/ bottom end. one or two tanks. someppl say break in for one tank i say taker slow, check ur elevation and pressure and temps, those all change jetting. few things to keep in mind not covered here love the vids man, you work harder then i do on my bikes.

[@utdesertghost199]

Very informative video, I wish this was out when I got my first two stroke. One thing I didn't hear before making jetting changes is along with having a new plug and clean air filter I to check the intake boot for cracks, especially in older bikes and also ensure the clamps are tight before you do a preliminary test. I also have to say the Lectron is awesome. I got tired of messing with jetting because of the extreme elevation and temp changes I ride in. This this is awesome, I only made a small initial adjustment when I got it last summer and have ridden it through the winter and from 3000 ft to over 10000 feet with no adjustment and no sponge. Thanks for the video, I'm sure that took alot of effort to make.

[@Jacksonflax]

Just bought a Lectron for my CR250 and it changed my life... The thought of that old TMX keeps me up at night. However this video was top notch (as always) Nothing left out and kept it straight to the point. also cant wait for you to murder another CR... I could use some parts :)

[@dwightschrute3862]

I know this video is old, but you’ve commented on my comments a few times, so you may help here. What would cause it to rev super slow, but once it hits 3k rpm, it seems to just pick up and go.

On 4 stroke depends where air/fuel screw is located. Closer to airbox, tighter screw makes fuel richer and air leaner. If screw is near engine the opposite.

one has to remember, Idle jet impact as well up to 1/2 throttle, Main jet will impact the needle and vise versa. so you should be carefull if you need to lover your needle (to make it leaner) as it may make the WOT lean in combination with main jet, and vise versa, if you have reduced the Main jet you might need to raise the needle.

Hey Cameron great video as always! The part about the float bowl screws stripping or chewing out is spot on, mikuni and a lot of other screws/bolts on a Japanese parts/bikes are JIS - Japanese Industrial Standard and if you use a Phillips screwdriver you can easily cam out and chew up the screw. There is normally a small dot embossed on the screw head to confirm, but if in doubt and a Phillips driver is starting to chew it, stop and use the correct driver, available from Japan and it saves so much hassle drilling out screws/bolts

[@mijailfernandezr.5924]

What a great video Cameron, thanks for keep making videos of two stroke,please continue.

[@lancairw867]

A good example of lean is when you let your bike idle and then turn the gas off. Once the the fuel from the bowl is nearly empty, you get that racy climbing rpm before the Motor dies. Edit: by far the best and clearest explanation inner workings of a carb 👍🏼
