Might be time to consider a center main strap - comes with two new longer bolts.
Having done some research into main straps for 998s, I've gone down the route of steel caps and a line bore.
The product shown is about as much use as tits on a bull... If you machine the centre main down in the manner described (and as done for a 1275 strap) you lose your thrust bearing locating tangs, as well as drastically weakening the cap. My the time you've had the tangs re-machined, you might as well do it properly.
for steel
I've reused bolts for years - as long as the engine hasn't obviously been abused, I see no harm in it for road use.
take off is more than compensated for by the strap. As Keith Calver says "what is possible vs what is necessary" So yes it is possible
to spend some 200 GBP for a set of steel caps and what another 100 or so with the machinist; vs around 8GBP - 20USD for the strap kit
and then the machining ... but then I hear "road use" so all that is necessary is just the missing bolts - without the bull.

As for the line bore if required the bore will be restored to std housing bore size. Only the crank journals will have to do with bearing size. Have you decided which tranny you plan to use and are you keeping the floor mount starter button? Steve (CTR)
