i have a cw 140 big wheel thats also based on the crf110. Im just wondering if you were to buy crf110 plastics off of a site like 24mx or something would they fit my pitbike?

I’ve just bought the m2r 160 it cuts out every time I kick it up before it cuts out it makes a bang in the engine can someone help me please

[@spaceggboysami9678]

Is ur m2r the dirtbike or the pit bike version?

[@alfiejones4253]

Hey mate. Is the rf160 any reliable and how long have u had it for. Also have you had to replace any of the parts

[@DarrenMcKinney1]

Hi Alfie, I’ve had this bike for a bit over a year now and it has been very reliable. I haven’t had anything break or wear out on it but the main let down with the bike is the carb and getting it setup right. It can be difficult as it’s a cheaper carb but apart from that I’ve had no issues even with putting over 500 miles on the road on her

[@andrewroberts7606]

Hi, just wondering what oil you use for the RF160 got mine yesterday and haven't haven't had bikes for years, thanks

[@DarrenMcKinney1]

I use a 10w40 semi synthetic in mine. Doesn’t really matter which brand but I use Comma in mine

[@rafirahman565]

Hi I have a question for the kmxr125 how do you put petrol in it do you just fill it up with petrol from the petrol pump or have to mix in oils as well

[@DarrenMcKinney1]

Hi, no these bikes have 4 stroke engines so you don’t need to mix with anything just you regular petrol

[@sugarboylewis7972]

Just read one of your reply’s to a comment...what did you have to change about your carb mate. Many thanks

[@DarrenMcKinney1]

Im not just 100% sure of what comment you mean but the main thing I had to do with the carbs on these bikes was get them setup so it would start hot and cold. They were an absolute pain to start with and with no real equipment to test or setup the carbs it took a lot of fettling but I eventually got it sorted. Main problem was getting the idle jet set just right but I found that around the 1 and 3/4 to 2 turns out mark was fairly close

[@brianruffner8116]

Do they ship to the us

[@ryanmenzies9490]

Just bought the kmxr and it’s not kicking well and cuts out before a kick into gear..Was told a need to tune it..could you guide me if possible?

[@DarrenMcKinney1]

Yes they can be a bit of a pain to get setup right. You will need to start by setting the idle mixture screw at the front of the carb to 2 turns out and set the idle speed screw so that it is lifting the cylinder inside the carb ever so slightly. You can see this by removing the air filter. If it still refuses to start keep turning the idle mixture screw a 1/4 turn at a time to see if this helps. It will take a lot of adjusting and I know it’s no fun but it’s the only way to get them setup

[@leighdee951]

I have kmxr with vm26 carb and it lifts in 1st and 2nd just from blipping no need to pull up at all it's an aggressive little thing I also was wondering where to set the fuel screw at bottom of carb I will try 2 turns out I currently have it 1and 1/2 turns out it starts 1st kick when warm but usually takes 3 or 4 when cold but great little bikes I must say

[@leighdee951]

Mine is 140 cc I forgot to mention that

[@DarrenMcKinney1]

Yeah great little bikes. I have mine at around 2 to 2 and a quarter turns out on both bikes. This helps the cold start although I found on the rf160 that it was then hard to start hot so I had to move the clip on the throttle needle one notch leaner and that fixed it so it started easy hot and cold.

[@leighdee951]

DMK Cycles ok thanks for that info so leaning the clip on throttle would be raising the clip one notch yeah?

[@DarrenMcKinney1]

@@leighdee951 yes that’s right. Raising it leans it out but just try the idle adjustment first and see how it reacts as they can take a bit of fiddling to get right and each bike reacts a little different

Hi not sure if you will reply as its an old video but im looking into getting the rf160 and was just wondering if the rf160 is smaller than the kmxr as i have a 125 at the minute but like the bigger frame of pit bike so dont want to get the rf160 and it be about the size of a crf50 as looking on fun bikes it shows its way smaller any help would be really appreciated 👍🏼

No problem. The rf160 has the bigger frame. It has a very slightly taller seat height compared to the Kmxr160 but they are pretty much the same size of bike. Hope this helps

Hi there i have a couple of questions first of all what bike would you recommend more and second of all would you say there is much difference between the RF160 and the RF140 thanks for your time.

[@DarrenMcKinney1]

Hi, in my personal opinion if you are doing off road only I like the KMXR better but for the road I like the RF as the seat is a little more comfortable and the position of the handle bars I like too. They are both great bikes and I would honestly recommend either but if I just had to choose it would be the RF. As for the 140 or the 160 there is a difference but not a massive one. If you are not worried about all out power, want to save a few quid and just want to have fun the 140 would be fine but they are both great engines

Billy if you’re looking a better value oil I use Comma Two wheel 4 Stroke oil and if your looking a really good oil I use Motul 300V 10w40 oil. I purchased all my bikes through Fun Bikes.

[@billywizz8562]

Thank you

[@fury8995]

Which one do you think is better for racing?Thanks

[@DarrenMcKinney1]

In my own personal opinion I would pick the rf160. I found it to be more reliable and easier to work around the carb (which is obviously important when it comes to racing) and in general I just like the way the RF160’s engine puts down the power. I hope this helps.

[@fury8995]

@@DarrenMcKinney1 honestly that helped so much mate,my dream is to go motorcycle racing and I've come to the realisation that road racing is wayy too expensive for me to start outright in so I decided I'm going to enter the British minibikes championship.I wanted to know which was the better bike and hopefully I'll be able to make enough from a part time job to get the funds for it(but even if I work long hours five days a week for two months during the holidays, I'll only make £800) but I doubt I'm able to.Thanks for the advice anyways mate.Btw I was planning on using this on an off-road championship aswell as a supermoto one, which bike I better then?

Ive bought the rf 160 i dint suppose you remember how many turns out your fuel screw is the one underneath the carb im trying to set it up for cold and hot starts thanks in advance if you can helo in any way ,cheers

[@DarrenMcKinney1]

Yeah sure i remember. Mines is just over 2 turns out. You will find if it’s hard to start cold keep it on the rich side and if it’s hard to start hot make it a bit leaner. It’s a delicate balancing act but it will generally be around the 2 turns out. If it’s brand new just check the valve clearances too as I found one of mine was too tight. I think the inlet is 0.1 mm and the exhaust is 0.15mm. Also if it’s hard to start in general I find screwing up the idle helps too

[@helenlinnel5746]

As a person waiting till their 16 to get a 50cc what should I look for? Preferablely street legal

[@DarrenMcKinney1]

Hi Helen, thanks for the question. Speaking from experience I would recommend a used 50cc scooter or moped over the like of a pit bike as you wont have to go through the process of registering it for the road. Plus you will have lights which will allow you more hours on the saddle because once you get your CBT you'll just want to hop on and go for hours. Then once you are 17 you can move up to a 125cc which will open a lot more doors for you. The likes of a little rf125 pit bike all the way up to 125cc cruisers and sports bikes, whichever style of bike you prefer and feel more comfortable on. I hope this helps and welcome to the world of motorcycles and stay safe on the roads.

[@nickcompton4772]

what are your idle and air screw positions ? on the kmx

[@DarrenMcKinney1]

The air screw is pretty much impossible to access with the carb on. It’s at the very front on the bottom of the carb. If you look up in you may just about see it. I have mine set to 2 turns out. As for the idle screw on the Kmxr you will want to remove the screws from the cdi or ignition unit on the right hand side of the bike. You will then get access to the idle screw when it is moved to one side.

[@DarrenMcKinney1]

I have my air/fuel screw set to 2 turns out and as for the idle get the bike warmed up then just set the idle to an idle the bike seems happy at. I leave mine a little high as it leaves the bike less likely to stall

[@robbiewoosey9959]

I can’t get the bike to start up mate had it 3 days I can’t start it up can someone help

[@zbit3423]

Quick question how long did it take to start your rf160, just got mine and it takes a while to start and it kicks back a lot, I got it started yesterday and it wouldn’t idle so I turned the idle screw and now it does idle but it takes a while to start

[@DarrenMcKinney1]

It took quite a while the first time. Then can be a pain to start unless they are set up just so. The kick back is usually caused by a mixture of low idle and timing too far advanced but mainly the timing too far advanced. If you have access to some power tools you can remove the gear lever and flywheel cover on the left hand side of the bike and you will see the sensor. It is not adjustable but if you can slot the holes and move the sensor as far up as possible this will retard the timing and should cure the kick back. Keep around a 1mm to 1.5mm gap between the pick up on the flywheel (the little square) and the sensor. This can be hard to do on the bike but you can easily remove the sensor bracket from the sensor to do it off the bike. I hope this helps

[@zbit3423]

@@DarrenMcKinney1 thank you

[@philiphancock8324]

The kickback is caused by kicking it wrong, you must go just past top dead centre with the kickstart, also you shouldn't be throttling it when starting that will increase kickback ditch the standard carbs on these things you'll never get it to run right the pilot jet is what you need to go up on if it's hard to start they should start one kick with no throttle

[@ryanmenzies9490]

My kickback is deadly and again just can’t get it to idle and kick into gear before it cuts out

[@zbit3423]

@@ryanmenzies9490 if your try to start it put the choke on and once it starts to heat up turn the choke off, also try playing around with the idle screw to find the perfect idle, you should notice once the bike has heated up and been left to idle for a few mins it’ll sound a lot more crisp and louder, I posted this comment a year ago but I’ve learned Alot about these pit bikes in that time of owning my first bike (the rf160). Hope this helps

[@liamharrison4821]

How much did it cost in total to get the MR2 road legal ?

[@DarrenMcKinney1]

Liam it wasn’t too bad really. I’d say with the paper work and the road tax, Speedo and horn it cost no more than £250 to put it on the road. The insurance was the worst part which cost a bit over £300. They said it’s nothing to do with the rider, it’s the fact that it’s an odd bike that’s not on any list that they can find

[@mattycod2358]

I got mine new and it only runs with the choke on. Can anyone help me? It’s my first bike so I’m learning everything haha.

[@DarrenMcKinney1]

Check the idle screw at the bottom front of the carb. It should be around 2 to 2 and quarter turns out. Reset it by screwing it all the way in until it stops (don’t use much force) and then screw it out the 2 turns or so to see how it runs then

[@lilr3280]

How have u got it road legal mate I got the rf 125 an wanna get it on road

Yeah I have it in the road this last few months. I have done a first ride video and a few more videos on it if you want to check them out it will show you how they ride on the road and also 2 videos on how to do the NOVA application and do the V55 form

[@sanesaint8725]

You need to get lights blinkers

[@AegisGGS]

What ones lighter as imma buy one and I live in a flat

[@DarrenMcKinney1]

There wouldn’t really be much difference in the weight of the 2 of them that’s noticeable anyway but the Kmxr feels a lighter bike when your riding it so I would say it would be the ever so slightly lighter one of the 2

[@baileywills0765]

I’ve ordered the RM is there anything I should know about

[@DarrenMcKinney1]

No nothing major. Just make sure everything looks right when you get it as they can be very hard to get on the phone if there is any mistakes. You will find it will need a bit of tinkering with the carb to get it started and running right. A good start is to screw the idle mixture screw in full gently and screw it out 2 turns. This will give you a good starting point to get you going

There’s very little difference in them Charlie but the KMXR160 feels more gutsy down low and doesn’t like to Rev out as much where the RF160 likes to be revved more. After owning the 2 of them for a while I would definitely be more in favour of the RF160 though
