hello well here is the nightmare..
first off i have a 06 wr450f that i have changed over to a supermoto. for to and from work and weekend fun time.
i do my oil changes ever 800 miles. and keep the bike mantained very well
only prob i have had is the timming chain tenstioner spring broke and me lucky nothing else was hurt... this was 800 to 1200 miles ago
i was riding to a buddies house had a very nice wheelie going (on a private roadway )
When i let it down and the front wheel touched down a sound of crunching and baging happen and killed the bike instanly.
after the tear down i found the right intake valve has been destroyed as you see in the pics.
the right exhast vavle dos not shut all the way.
the piston head has pretty big diggs in it.
the piston walls look fine as well no scratches.
and the front chain dampener was bent near the bottom.
but the chain tenstioner was fine.
now the questions
what could of cause this?
how can i prevent it?
is the head saveable ?
and cost of the save?
anyone have one for sale ?
if i have to buy new parts where is the best place .
what years share the same part?
i found on most big name websites the assy head for 700$
im i correct to think that does not come with vavles?
and as for piston any suggestions? is it salvagable
if not what brand would be best choice?
any and all help is welcomed . thank you for reading
