Hole In Engine
Hole In Engine
Well i gave the bike a real good thrashing last weekend and suddenly all came to a sudden stop. When i looked at the front of the engine there is a hole the size of a 50p piece where the two sides of the engine meet at the bottom. Dont know if it blew from the inside or something flew up and smashed it. Has anyone had this happpen and i presume it will be a new engine casing. Can you buy just the casing and has anyone out there got one.
I feel this could be expensive

there are some casings on ebay, theyre from an ar but should be ok for all. Not cheap but better than buying new.

Re: Hole In Engine
Very likely that something came up and smashed it. Have you got a bashplate
Cases can be welded but with such a large hole you would need the missing piece/s. You might get away with welding on one side though depending on hole position
.
You will have to look at the bearings inside. Possibly you have siezed/bent the crank; or knocked something inside to jam gears
. Depends on where hole is. Have you got a photo
.
Take the engine out and split it before you rush off to buy anything.
What Mk have you got

Re: Hole In Engine
i recently had a large hole welded in a cr500 casing. They are £350 each to buy. welding cost £50 and they did a great job :)

Re: Hole In Engine
Thanks guys, todays task is to get the engine out and asess the damage. Some very helpfull comments.
On the topic of a bash plate, yes i have one but recently did an oil change and didnt get round to putting it back on... Could have been a costly mistake. Oh well you live and learn. I was giving it some in a stubble field and think the front wheel kicked up a piece of flint.
