Hi guys.

I got out a broken spark plug, and when i tried to put on the cam chain cover / valve cover. this one broke:






One guy on this forum sold me a set of these, coming in my mailbox any day know.

So i really need some help from you guys, how do i get them out ?
I are they linked togheter, so i have to unscrew them all and take them out ?
I tryed taking the screws of one of them and i can get it out..



Hope someone is able to help me ..

It is not many of these bikes in Norway..
And if i get it running, i am going to repaint it and make it a special one !

Anyone know how to get them out ?
Is it any thing i should know about, when i do this?

The cam caps are pretty much non replaceable. Reason being is they are machined individually for each head. So in escence you need a new head with cam caps that came with it. Buying the caps on thier own might work but i beilieve its the oil ways which wont line up.

When removing or replacing the cam cap the bolts need to be done up evenly like when you torque down the bolts on the head of an engine. tightening/undoing one all the way and doing the rest will stress the cap and break it.

the pictures is hard to see, but if its just the screw-hole for the rocker cover then you should be able to get one TIG/MIG welded on.

they will weld a rod of aluminium on, and then tap it so you have your screw hole.

if not, as rob said, its new head time...but i know which will be cheaper, a welder will charge no more than £50 to make you a new screw hole.

So in other words i have a big problem ?!

I already bought the second hand cam caps, and will try with them..

If not, i really dont know what 2 do

Thank you guys so much for replying .

will this fix my problem ?

It is from a H1 bike
