    250 4rt crank

    Thanks for the help, I’m going to put the new bearing in and see how the crank sits and judge any play, unfortunately due to the make up the loctite won’t be an option. I’ll see if I can sort out the YouTube link and post as well ? edited post with link ?

    250 4rt crank

    Thanks both, piston and pin are all ok, to be fair it was more of a rumble than a knock so I suspect the bearing. I can’t find any tolerance measurement for the crank so will replace the bearing and keep fingers crossed. I have a video of the play I found before the full strip but it won’t let me add that.

    250 4rt crank

    Ok so having completely stripped my 4rt intending to put new crank bearings in due to a knock I have found a little wear on the crank, flywheel side..... is this terminal and a new crank or could it be replaced? Also does any one know of an alternative CRF250 crank possibly ?‍♂️

    4rt engine work

    Just in the middle of splitting my 06 repsol that has a mild knock. Looking to replace main bearings seals and gaskets and see what the piston is like and hoping the crank is ok. I’ve had the bike from new and it’s on its original piston, it’s done 4 SSDTs but been cared for. I’m reasonably good on mechanics and done cam belts etc ... is there any pit falls with the 4 rt I should be aware of ? I’ve got clutch basket and flywheel off as we speak. Any advice appreciated......other than take it to a dealer !!
