I did a quick search but didn't find anything so I apologize if this is a bit "teaching your granny to suck eggs".
I was adjusting the primary chain today on the Silverstone and it occurred to me that a tip I found many years ago may not be common knowledge, especially for new owners of Challenger/Silverstones. I have modified the shims that fit between the engine and gearbox by cutting out a slot, making them U-shaped so they can be slipped over the 4 studs without having to remove the engine from the frame. Makes the job much less laborious than the "approved" method.
It is just a matter of slackening the 4 nuts that hold the engine/gearbox to the frame and doing the same with the 4 aluminum nuts (I made a thin spanner for this as a regular spanner will not fit in the space) and the gearbox can be gently levered back to provide enough space between engine and gearbox to insert an extra shim if the chain is slack.
