Can you put a 301 motor in a 250? The cbr300 is ugly AF.

I have seen the your video on MC Garage about new engine run in myth, but I still have doubt, those engines directly coming from factory are precisely built in machine process. Now since you have rebuilt this engine in your garage, did you let it run in for ideal for some time or did you just took it for ride like normal?

Hi bro Is it possible to fit CBR 300r fairing in CBR 250r

Would love to see more videos from you 😅

Make more cbr 250r videos

The fasteners you refer to as "bolts" are correctly called "screws". A bolt is used with a nut, and can have any of the common head types, socket, hex, torx, etc. Using the term "fastener" is usually appropriate. I worked as a mechanic many years and learned correct nomenclature only when becoming a mechanical design engineer. Do some research if you have questions!

Good to watch your CBR video. I just happened to have bought TWO 2012 CBR 250's this past month. My first one is red/silver and had set unmoved for 5 1/2 years. I got it running with cleaned fuel system and it also needed a chain and rear master cylinder. It runs beautiful and has just 6,408 miles on it. This one I paid $400. for. The bad news is the promised title may not be available anytime soon. Looking for an option on the internet I found another CBR in a red/white/and blue format in beautiful condition that has a rod knock for $500.. Later I will investigate why. Tomorrow morning the engine will come out of the red bike into my red,white, and blue Captain America CBR. I am a 75 year old retired auto mechanic whose only claim to fame is I won the National Alfa Romeo Mechanic's Championship in 1986. I really wanted to make the red/silver one into the best bike as I also own it's "Big Brother" a 2010 VFR1200f in the same color scheme. I have the perfect working environment for these builds in a large mobile home on my new property where my other 3 bikes are stored. Wish me luck! I, like you, enjoy making things because as mechanics we LOVED what we do.

what piston did you use on this built?

my 250r is having a knocking sound while accelerating even at neutral but It sounds normal at idle.

Hi can you help me will a cbr300r 2014 take a 2015 engine? Many thanks

I love the vid. I know it 4 years old vid. But this old cbr engine has really good base for tuning

Small 4 strokes aren't tough these days

Hey bro. I enjoyed your video. Just thought I'd say my 2012 cbr250r has a litle over 95000 km on it. Never opened up the motor. Have it for a litle over 8 years now.

Very good assembled Man thanks I learned very much.

I need your help!

If you got a spare head let me know if buy it

A million thanks to you. My 2016 KTM Duke 390 was poorly and just suddenly became difficult to start . Then, it dropped a valve or something similar resulting in a wrecked head , piston etc. I sourced the parts mainly from India . It was setting the valve timing that freaked me but after watching your detailed video of how to set the timing on a KTM RC 390 , I got inspired. Rebuild was completed last week with the help of a talented Philippine mechanic ( first time for us both to tear down a KTM ) Thanks again for your inspirational videos.

I know it's been 5 years, but I would love it if you did more videos like this.

7 count ligth

Honda cbr 150r engine light blinking what's problem

Another vote for there being more of these.

Great video. You make it look easy. I decided I'm not going to pay places to put new tires on my bikes anymore. I bought new tires, a tire changing stand with bead breaker and a set of tire irons and stuff. Going to give it a go in a few weeks when the weather warms up here in Ohio. I will be replacing tires on a 2013 Honda CBR 250R and a 2006 BMW F650 GS. Wish me luck!!

Hey Ari, thanks for the nice video on the CBR 250R engine repair! I own one at the moment but my 250R makes a high pitch squeaking noise when it runs and was wondering if you have any idea as to what it is? I've replaced the clutch plates because the squeaking noise gets louder when I engage the clutch. So, I don't really hear it while it's idling but I hear it when I'm in gear and driving. Please let me know if you are familiar with this sound on the 250R. Thanks again!

Email id please

Do you sale whole motors?

Only one video!? :( I thought I found the mother load of Ari vids lol

Ari needs to post home videos again, because this is a gem

Good insight

Your video is very educational!! Because the part of the world I’m at I don’t trust the mechanics!!!!

Also would like to know what you did with the air box? I have gotten rid a few of them myself over the years.

I know this is an old video but if you still respond to comments I have a 2011 CBR 250 with 190k kilometers, yes. It has never really been worked on and now the engine is tired. I am considering having a big bore done as opposed to just a rebuild, what do you think? Great video, your OCD and motorcycle skills combine nicely.

hi Ari.. I'm a fan from philippines and been watching all your videos in MC garage for a year now. before I always bring my bike to a bike shop. Now I decided to study it and do it my self.. because of your tutorials I learned a lot, and now I'm doing everything to my self except for Motorcycle wiring.. Can you please make a tutorial for this. I love the way you deliver your knowledge, It's so easy to understand,... Thank you so much and ride safe always..:)

They’re not the sweetest sounding bike to be honest but good work on saving another cbr from the scrap heap.! Do you know why the balance shaft sheared off like it did! Just bad luck maybe?

Ari , come on back. Ive watched just about every video of yours out there. Need more content and you're by far the best in the business! Maybe a cross over with Aaron Colton?

Why did I just discover this?

Hey I got a cbr 250 bike with a wrecked engine I'm looking for somebody to build me a race engine for it

We miss you, Ari.

Helps to have an understanding wife!!

That reminds me of the time I helped my wife fix her honda 305 dream

How can i store the bike for a long period time can I do that

Wow! Impressed and congratulations! I would probably have done a boat anchor with such damaged engine!

You are the only reason i watch mc garage videos even after its 7 years old , man love your videos , continue and we will support you... Love from india .

I know I'm late to the game, but that was a great video. I'm actually thinking of getting a little 250 myself. Keep up the great work!

You are the man. Hope to see more videos / adventures / challenges in the future. best regards.

Should do this for revzilla... take broken bikes and build it up... maybe a build up to track bike

Hi my name is joy . I want to know that can i fit cbr 300r block piston in my cbr 250r
