No apologies indeed, I for one am very interested as a former Scrambler owner, I always thought the Monster was Scrambleresque in ways anyway.
As for the decompressor I don't think 250s were ever fitted with it, 450s definitely and I think also the 350.
I wish I'd kept mine, I gave it away after the big end went as I was moving house and couldn't be bothered to fix it...
