    White smoking

    Post by frank spencer on Wed Aug 10, 2011 8:56 pm

    A mate of mine has been offered a cr 250 that needs a bit of work.

    He,s not interested in it himself so im in with a chance of it.

    As i say it needs a bit of work not been mot,ed for a while (is registered) The main problem is its blowing white smoke? quite a bit.

    Idea on a post card please as to what you think is wrong with it and what i should be paying for it?

    thanks chaps



    definitely going to be out on the dirt this winter with a bit of luck.

    Is the bike using any water or gearbox oil?

    does it run ok?

    are the rads pressurising?

    It could also your crank shaft oil seals. Check your plug and see what colour it is.

    Should give you a good idea if its black and oily then its burning oil.

    Been to see the bike this morning and decided to give it a miss,

    There was very little oil in the gearbox and no water in the rads either.

    Did sound nice but needs a bit to much work for me.



    Thats for the sound advice cheers

    could be as simple as incorrect mix or blocked filter.....or something more sinister gasket or ring blown!

    Definately crank seals you made the right choice! Rolling Eyes
