my (dads) K1100 build ( Red Hot )
Hi All ,

Bought my dad a k1100 head for xmas , also the SC build Manual...

lost pictures of the head ,but most people know what they look like :)

anyway , dad just doing it in spare time and when he is bored , we had a spare 1275 A+ engine laying around so will use that as a base.

for now , he has got it stripped ,and has blocked off old stud holes in block.

still waiting for someone to send my dad me some long head studs (cough Ardonfast)

I coughs so hard I woke up in your loverly sister:D
I've pulled them 4 long studs out of the ( a ) block they was new in 1992'
And when I sat rolling up a snought the smell of the fag was the same as that day, ile post tomorrow

Dad created a tool for marking new stud centres , different bushes are required as holes in BMW head are different sizes, ( centre punch )


3mm pilot hole then drilled and then centre drilled to a diameter of .375


Centre drill stops larger drills from wondering , then drilled in steps of 1mm to 5/16 dia for tapping.

two more long studs required (ardonfast ! )
Head now slides over new stud positions a treat.

block now needs boring and onto next stage.

work out what to do about pistons now , make some , or buy some ?

Got some honda st 1100 bike cam pulleys. Dad is going with them for now

First job to bore bottom pulley to 1 inch dia. Dad made tool to old it in lathe. Not wood pegs :)

Matt, how comes you want the cams chopped up? I can cut them down to 6ins?

I know nothing about these k1100 setups

MattG 16-03-2014 09:36 PM

My dad only needs ends to make adaptors for Honda cam pulleys onto BMW cams Simpler to make if you allready have cam / locating slots etx.

Honda bike can pulleys are same as Honda car pulleys ( well mountings anyway )

Kam 16-03-2014 09:49 PM

Ahhh I see, no worries

Postman Pat will be processing them tomorrow...

some cam pulley spacers made up for testing positions


and the honda st1100 bike cam pulleys in place , also he has made one fit onto mini cam, but needs a spacer etc made.

looks really good :)

have a closer look on the angle of grip for the cam belt. in you case case it looks rather small.
do these pulleys all come from the same engine ??
the 3 big ones look a bit too big for me. how many teeth do the big ones and the small one have ??


what did your dad use to close the holes in the block that are not used ??

MattG 21-03-2014 02:56 PM

they do come from same engine , (Honda st1100 bike engine )

looking at other conversion pics , top pulleys have same gap..
