    How many hours can be expected on the Honda engine before it’s rebuilt? Considering proper maintenance is done?

    Hello. How often do you have to replace the piston and rings in this engine? Greetings from Poland.

    One reason why I hate 4stroke engines, good job on the rebuild 👍 only smokers for me cheaper and easier to fix

      you got it I would buy 1 if I was loaded just for an extra bike for some 1 to ride etcetc I would take it out to of course but when I seen all the maintenance even the oil change`s its just as much or more than a 2 stroke which you would think shouldn't be

      @@mike300406 see I used to think that but all 2t bikes eventually required a complete rebuild due to wear.. mains and big end don't have the benefit of a lovely oil sump to keep em well lubed. I've done too many to count. Next bike is a mont see how I get on with it

    (I looked it up) it is a low compression bike vs. others and that is why there is no high end speed. It only needs to make you move vs. take off on the slopes...

    Did you replace the rod?If so what make and part no and where did you get it from?
    Thanks.

      We used Pro X conrod for a CRF250X supplied by Ecosse MX who sell on ebay.Honda don't supply a conrod separately ,its a complete crank from them.If you bend the rod then you will have buckled the piston skirt too.New piston required.All parts used were genuine Honda other than the rod.

    • @canadapainter658
      @canadapainter658 7 ปีที่แล้ว

      Steven = it is funny It got so slow top speed as 250cc. A 125cc regular 4Stroke bike can 110km/h top.

    • @Oldbrokenbones
      @Oldbrokenbones  7 ปีที่แล้ว

      It's down to gearing and the purpose it was built for, I'd like to see anything else ride up a near vertical waterfall..........

    • @canadapainter658
      @canadapainter658 7 ปีที่แล้ว

      Steven = vertical clime is not bike power it is momentum. Power is there to get momentum.Also I wonder what gearing has to do with it... since a big sprocket in the back can fix torque issue.

    what means Hydro Locked Engine ? thank's

    • @jvboy56
      @jvboy56 7 ปีที่แล้ว +1

      Hydro locked is when a engine has a liquid in the top end which will not compress resulting in the engine not being able to turn over and usually causes damage such as you see here (bent rod) a cracked cylinder ,head or gasket failure can cause this problem as well as the engine sucking in water through if the carb becomes submerged

      @@jvboy56 But, how did these get hydro locked? Once had a riding partner in an enduro that sunk his OSSA Plonker in a stream and we had to turn it upside down once on the banks, remove the plug, and turn over and over til it was relieved enough. Was a bugger to restart but he went on to finish w/no rod damage.

    Rod from a CR250! call Micky Oats in Glasgow, tell him you need the same parts for a rebuild, same as the Dundee guy's, he's a fine guy, and will have the parts listed........ 0141 332 7374, we ended up changing the piston too, as there was a little slap we couldn't live with?
