Wondering if all the mag flanges are the same or if some are deeper depending on year similar to the flywheel cowl different depths?

I ask as I have a S3 mag cowl with the rubber grommets and to get all the bolt holes lined up It leaves quite a big gap where it meets the cylinder cowl as the rear of the mag cowl has to be moved onwards.

If the lip on the mag cowl was about 1cm deeper it would fit perfectly.

a picture or 2 would help explain the problem . Are your mag and engine cowls OEM ? Innocenti ... SIL.... Spanish or aftermarket jobbies ?
I had to do quite a bit of butchery to my S3 cowl to get it to fit right.

I think the S1 is slightly different internally. But as far as I know they all share the same external measurements.

150 mag housings differ from 200 ones not externally though as far as i'm aware,recent new indian ones are a tighter fit than the original italian ones on italian blocks not sure if they are tight on indian blocks though or if the external diameter is different.Cowlings wise several different ones tbh look in stickys book for the differences see which one matches yours even some of the italian ones are pretty poor fitting wise.
the man don't give a f@@k

The 150 and 200 maghousing differ only on the cut out on the right side transfer the 150 is smaller and you can dremmel it to fit a 200 but not the other way round

The series 1 flange also has a larger diameter outer seal that is accessible from the outside. Sorry just saying.

The cylinder cowl can be a deep one to match the deeper mag cowl(SIL)as the flywheel has longer fins.
