i am getting a bit fidgety about the spacing on 998cc bores and the k100 head i have just bought but no yet received.

Anyone know the bore spacing of a 998cc? and/or the spacing of the chambers on a k100rt head?

OR better still can someone do a pic of a k100 head with a 998cc gasket laid over the top.

I was reliably informed that a 998 will work ok with this conversion but i am getting concerned.

surely if it works on an 850cc engine then it will on my 998(possible massive ignorance of the 850 engine showing there)???????????????

HELP set my mind at rest pleeeeaaasssseeeeee

You could PM STIG and ask him to show you a piccy of a K100 head with a 998 gasket laid over the top of the chambers?

Matt, don't worry, it'll be fine!

This link may help you. Im not sure which each colour represents though!

to be honest for the hassel of making it fit a 998 block, you'd be better off doing a short stroke 1275 if your wanting to keep the cc's down? Would be nice and revy too.

This is a 998 spacing. You can see the is a massive gap between cylinder 2 and 3 compared to the 1275 block and 850.



This is an 850 block with a K gasket on.

i am not desperate to keep the small bore it is just taht that is all i have and it is haerd for me to get a cheap 1275 here.

so 998 it is as long as i can get it to work. maybe i should try and find an 850 engine?

[miniboo]

well those are also the thoughts that i had, ratty.

i have literally just recieved the head and offered up a 998 gasket and it looks ok to me. pics to follow in my project thread.



VERY VERY HAPPY!!!!

might just be my imagination about he pics, but the top picture doesnt look like a 998, the gap looks a little too big between 2 and 3 , the bottom pic look smore like a 998

[miniboo]

botoom pic is an 850 cowboy and looking at my 998 block i think the top one is a 998

[Xiao_Bin]

my 998 is open at the moment and it really doesnt looks like the 1st one

[miniboo]

it does look a bit OTT but mine is defo simlar maybe not as big a gap on the centre 2 bores but then that one is nice and clean and freshly built and mine is covered in C**p.

[Xiao_Bin]

oh carp you're right, I was looking at my gasket
the block is the same

[matty...]

The bottom pic is from the miniman website (bloke that did the first K conversion) and he used an 850 block.

Im sure you probably would of read this before but just incase.
