What's to be perplexed about?

It's a series 1 casing welded and machined to 200 stud pattern courtesy of Oiltek....

the casing i am using has good threads and the mounting brackets for the exhaust are rubber mounted and probably the best design I have seen , mb rev-tour. just another idea some jonny come lately told me about was to tap the engine case side casing and put the studs in there ?.

I thought it was a reasonable idea, cant see any major drawbacks with this idea ??. just to add the threads are very good in my case. so I don't need to repair them ........... yet.

I'm thinking that Innocenti changed to 8mm studs as 6mm wasn't up to the job, even on the piddly little standard boxes available at the time.

Just an idea...

Hi, think that there might be some mis-interpretation going on the comments. The case looks very well prepared (have seen the oiltek method and am impressed enough to go same route). What I was trying to say was that when you stated:

and showed a picture with reinforcements on the chaincase side, rather then additional material on the main case stud surrounds, that tea5ive might misinterpret that as sufficient despite your comment

Being under the impression that it was an oversight on tea5ive's behalf, the engine was done and that a full strip to get the main case welded and planed back on the gasket face was not on the cards.

In this case I thought the stepped studs would be a better alternative to plain M6, and that with a correctly installed rubber mounted floating exhaust system, there was a good chance that there would be no issue. With the fallback that if there was then there would be no more work involved than at this point in time?

Yes with you now - I'll whip the cover off and take some more pictures.

No misinterpretation from me

Just a wee oversight then! So what is the plan?

Here's the plan first drill out the side case to clear m8 studs and use the stepped studs m6/m8 as the mounting bracket will also be m8 cleared. If this fails I will have to strip, weld and re tap to m8 . I fitted a few dev/rev tours in the past and have fitted with no problems, even when using packers under cylinders. Will also try and find some high tensile stepped studs or turn down some m8 bolts to m6 just on the ends, high tensile. What do you think..?
