Wicked tutorial. On the 2017 250r the owners manual says 0.008 for exhaust valve clearance, which is a misprint it should be 0.011, like the 2014. The misprint might be just in manuals for Canadian bikes but just wanted to post this some where that people might see it before taking it all apart like I did!!
Also could you link what engine oil you used when reassembling the bike. Also could you link the took you used to measure the width of the shims. Thanks!
How have the valves been on your bike? I just bought a 14 rode it twice and now it won’t start cold. I’m assuming my intake valves are tight. But I’ve been reading a lot of mixed reviews on hondas valves. I’d love to hear your experience. Thanks
The bike has been running stroung since I made the adjustment. I have a 2015 CRF250R bike has never had it's valves done and still starts first couple kicks cold. My buddies Kawi is having issues with cold starts I believe his valves are off the fix should be a valve adjustment.
Hello I've got an issue where it wont run after doing the clearances, the cam is not 180 out and the clearances are writhin spec all the timing Mark's are ok but it will only fire and then cut, anybody help?
I have a 14 model too, would this be the cause for the hard time cranking at cold weather? I can tell it wants to, but never does I have to roll start it. I was thinking of a wiseco higher compression piston too, would valve and shim and piston upgrade help? I think it should, or maybe for now just valve adjustments
Yes the valves could be too tight resulting in difficult start. Do your valves first and then upgrade. Remember higher compression piston requires the use of race fuel.
Unless you’ve had your bike sitting in your garage or whatever for a year waiting for a response, it doesn’t matter where your chain is as long as your top dead center marks on the cam gear and on the bottom crank line up
i got a 2014 crf250r about a year ago and it blew up the first time and i got it fixed during covid and it took 8 months. So ive been riding it for about three and it blew up again 3 days ago. Possibly the worst bike ive ever owned
