went for a ride yestaday on the return leg from our forest loop the bike cut out .would not start as if to hot

:?: then had a look in the oil window full to the brim with white looking **** not good me thinks. talking to clarkies they said best to whip the head off and cheak out the head gasket rather than just change the water pump seals. any one else had the same snag any how i won,t be swapping to orange like someone we know dont we mr brooke :shock:

This is the exact problem that we had with a few of the 750cc kits as mentioned in my last post on that thread. We had milk (an emulsion of oil and water) in the gearbox, and the starting problem again like it was hot.

Once we fixed the head sealing problem it disappeared completely, I would say the head gasket is probably your culprit as well.

Best of luck your cow.

When you talk about switching to orange,please say you are not talking about the color of the radiator fluid. I have been running orange for three months. 8O

can i ask what model you are having the problem with some models have a o-ring in the clutch case that seals water it could be just the o-ring or gasket if the clutch case took a knock while rideing it possibly could disturb the seal just a thouht eay to pull the cver off than to pull the head off

I had the exact same problem with my 2001 FC 550. I replaced both the seals and the O rings at the water pump. It still leaked. i then replaced the cylinder head. It still leaked. I finally split the case and replaced the three O rings at the base of the cylinder. No leak now. I was able to remove the cylinder and replace it without removing the crank shaft. It's tight but not difficult. All in all an inexpensive but time consuming fix.
Good luck.
