Look at those little connecting rods!! The stroke on this engine was only 3 centimeters. Mind boggling how the distance of half your finger is translated into incredible amounts of power. I love it thanks.
The cbr250 isnt a fireblade guys, title is misleading. Weirdly, i'm more inclined to watch it now i know its a cbr250(the proper one with 4cyl) as i love how rev happy they are
The cbr250rr was indeed openly marketed as a fireblade in many countries. It was to tempt new riders into its bigger brother later down the line. I own a 250rr and 900rr myself.
Where did you find all the parts for the rebuild? The pistons, rings, bearings, etc? I'm planning on rebuilding mine and this is a great example to follow! Thanks!

Never unscrew a camshaft this way. The valve springs are pushing from one side and try to bend or break the camshaft, even though these camshafts are relative short. The last bearing block may not take the force of this leverage.

U should close your workshop and open a chana papdi stall or barber shop 😂😂 Putting gasket and rtv together? Bravo 👏 and doesn't warped the cylinder surface and head. u will get success when the world's end.😂😂😂
No. Everyone with eyes knows its not firing. These idiots dont even know what a torwue wrench is for. They were torquing accessory fasteners. But didnt torque the cam journals. Or crank caps. They also didnt put oil on anything. I wouldn't look to them for any knowledge they do this only for money from youtube.
@@krotchlickmeugh627 probably wouldn't matter if they had torqued them. Their torque wrench is probably shot. It looked like they were using it to break bolts loose I stead of a breaker bar lol.
If the jets are clogged and they didn't clean and adjust the carbs, it will be misfiring. But there are also other 'issues', like valve clearance check that wasn't shown in the video. I see new pistons, new rings, but were the cylinders reglazed ? Or the valve seats re-cut and polished ?

@@alexanderkusaev1066 автор имел в виду не конструкцию мотора, а метод очистки его тех узлов да и его в целом, множество действий в данном видео показано в процессе чистки, которые подвергают мотор сильному сокращению ресурсу (грубая чистка, в некоторых местах и вовсе неправильная)
They didn't show the state of the bore, the crank journals, the valve seats, I can't even tell if they stuck new big end bearings in. I'd like to know why what was wrong with it to begin with to understand what they did to 'fix' it. My guess is probably ruined bores from overheating after seeing the broken water pump in which case new rings and a black paintjob aren't going to solve your issues.
I thought u were supposed to turn the engine crank with a wrench as rebuilding it? so it doesn't explode when you start it from the new grooves and lands in the cylinder walls? Or is he using the original internals?
I had nc29 cbr 400rr gull arm (baby blade/fireblade) and it had tons of head work for track days (and road use alike! It was dyno jetted, ported, polished, race ignition, the works.. I regretted getting rid of that one the most, and I've had dozens of every kind of bike from z 1000's to Harleys, magna to vfrs.. I had 2 cbr 250's, (both types mc19 and22) 2 cbr 400's the nc23 and 29, the cbr 600f, the 900rr fireblade and a cbr 1000f, and that little 400rr was my favourite of the bunch! The baby blade and the vfr are two of my favourite all time bikes, the gear driven cams are amazing, makes the engine run like a Swiss watch! As for the vfr, that v4 sound along with the gear cam whine sounds like nothing else
Might wanna upgrade the regulator on this model of bike, mine blew not long ago just from added heated grips and led lights. Not sure what to upgrade too, or even if I can just use any old regulator like one from an r6 or something that can handle more electronics, but definitely put some thermal compound on it once you install it so it transfers heat to the frame better.
@kennethconnors53 - didn’t you know, there’s a whole army of people out there dumping and trashing motorcycles just so restorers like these can “find” them on their travels (normally followed by another chap with a camera just in case of such a “find” - how lucky is that?). Furthermore, none of these bikes have registered owners so ownership automatically transfers to the restorers.
The babyblade awesome little bike i have one and a spare engine aswell going to do this soon my self thanks for the video guys i want to hear it hit at lest 18,000 rpm i have the unrestrided one hits 20,000rpm so sweet sound.
Crip Mac says this motor nifty but he said it only go 55 mph I said nah it'll break 100 he said on neighborhood Crip it's only hit the big 5.....if ya know you know. Drink water. Don't commit suicide. Stay alive. Big 5.
Hmm, bit of an unorthodox pattern for loosening cam bearings and head stays, ending up still fully torqued at one end of the head with all the other bolts loose is not really ideal, but anyway..
Yikes. I skipped about a few times and everything I saw was bad. 17:03 Use some bearing retainer FFS. I bet they didn't use thread lock anywhere either. 22:48 Sealant always goes to the INSIDE edge of the holes on a flange. Now oil will weep out from the bolts. A gasket as it would have had originally is much better. And who uses white sealant on a black engine anyway? 24:51 Please tell me that's not sealant on the head gasket...
@@Jason.cbr1000rr RTV is a silicone sealant... I couldn't believe it either. Yeah, they are poor, but they are wasting RTV putting it on a head gasket, and risking blowing up the engine. Poor people are driven to be creative and smart with their lack of resources, not lazy or unknowledgeable
To quote from Ryan F9: "If I were a Swiss watch maker, I would take one look at the CBR and then shoot myself". The whole rebuild from the pencil valve heads, camshaft, timing gear, clutch pack and down to the rotor got me speechless. Again, if I were to put those back together after disassembly, at that point I'd do the same thing like the watch maker.
The engineering on these Honda engines are truly amazing, just like a fine handmade swiss watch...Damn Honda u scary :)
Japanese beast❤
This is not a restoration. This is engine painting and assembly on dead spare parts. And that damn sealant, sealant everywhere. OMFG
Yes, I agree. Sealant everywhere, he even didn't tear off excess of sealant... And the old rusty coolant pump... Cylinders surfaces...
The people that don't know about engine rebuilding will look at this and think it's cool.. the few of us that know will cringe 😬
I cringed looking at the fucked pump. The whole video was just a facelift for a dying engine
Look at those little connecting rods!! The stroke on this engine was only 3 centimeters. Mind boggling how the distance of half your finger is translated into incredible amounts of power. I love it thanks.
lots and lots and LOTS of rpms, it is the only way also look how tiny those little pistons are, they look like free samples of a real piston.
26:02 my heart skipped a beat🤣
Different carbys, no valve adjustments?
Paint sprayed for good look, no more.
Que montón de piezas! Más piezas = más variables en la ecuación = más probabilidad de fallas. Excelente trabajo Señores. Mi admiración total!

Never unscrew a camshaft this way. The valve springs are pushing from one side and try to bend or break the camshaft, even though these camshafts are relative short. The last bearing block may not take the force of this leverage.
