This got me through my rebuild woulda been lost without it! Precciate ya bro👍
Solid video. I lost it at the screwdriver bit part 😂
Great video dude... just finished rebuilding the top end on an 09. Thanks for editing out all the non-critical pieces of vid and keeping the good stuff in.
I just got one of these just a year newer. When it blows up im gonna refer to this
Mine blew up yesterday
@@motomash6143 oof goodluck homie
Great video, thanks for the information it was very helpful
Thanks
great vid!
Helpful video, thanks bud
very helpful vid thanks
No mention about shimming the valve clearances, very important on this model. If that head came set up perfectly, that's worthy of mention, because normally they won't.
4:10 so fucking hilarious. I’ve never heard someone speak the truth like the way you did😂
2010 and 2011 crf250r blowing up fast because when you push the stop button the fuel injection still give fuel to the engine and then it thin the oil. Change oil every 1-2 hours!
If you could properly spell.
Nice video. Did the bike already have a new crank in it when you got it? Im thinking about replacing my crank and just wondering if its a nessesity when i replace the piston. Its a 2012 crf250r with 100 hours. Runs great now but i want to make sure it stays that way.
I did not. Generally if the crank bearings feel right I dont tear stuff apart. Of course when you are flipping bikes vs. something you bought to keep long term the priorities are a little different.
Ok thanks for the reply. I havent ever replaced a crank in any 2 strokes and havent ever had a problem with them but ive heard for some reason 4 strokes cranks dont last as long. Ill probably just buy the full kit though. Thanks.
No checking ring gap or piston to cylinder clearance??
Hi, did you have to remove the left side crank case to remove the cam chain guide? I have a 2010 crf250 and im about the do the top end
No i did not.
Working in the dark need light on the engine so we can see what you are doing
Like the shirt bro
Hey, Maks. Just out of curiosity, how much (ball-park) did it end up costing for the replacement head? Did it leave you with enough profitability to justify all the labor you did?
Thanks!
Mike
Nice thing about dirt bikes is that they come apart quick and go together quick. So not much labor involved especially if you have done a few.
used jug - $75
used head - $328
gaskets - $70
Piston - $135
Plus i got some extra parts i will sell. My guess is when all is said and done I will have around $850 in the bike. So to me its worth it.
Head bolts on these bikes don’t have to be replaced they aren’t torque to yield. Now when it comes to honing the cylinders, it’s debatable on these in specific. All the race bikes have nikasyl bores which is super super thin. You shouldn’t Hone them just clean them really really well
Hi i am now doing a top end on a 2012 crf250 can u help with the torque settings for head bolts and cam caps in nm
Check out carlsalter.com. they have manuals
Screw driver bit in the cylinder.... whao
What website did you find a bike that looks that nice for only $350?
I get almost all my bikes via private sale. Like craigslist.
Ive never seen one that cheap even blown up
I wish
Even blown up they are always over $1000 around here .
Also i have a question i want to buy a used 250f but im on a tight budget
How important is it to get a fuel injection bike?
Im thinking i want fuel injection for easy starting but how , much of a performance difference is there ?
And if you could get a really good price would you consider a bike that didnt have fuel injection?
Tarz Thomas believe me, I just got a fuel injected 250 and they are so much more better than a carburetor 250. Carburetors are so much work to get jetting right. Spend the extra money for convenience and better starting you won’t regret it
When did joe Rogan become a bike mechanic
Over rev? Lol
