Basically on Christmas day the LH slide plate on the sport parted company and went om nom nom into the cylinder, fortunately at idle and it got shut down straight away (if it starts make a bad noise turn it off straight away!). So other than a small bing in the barrel not where the rings run most bits are serviceable, well as serviceable as something that has been flogged pretty hard for 140 000kms can be (90 000 odd miles). So its in bits we are going new rings cam followers valve guides, valves if required cam chain/sprockets or gears and possibly a cam again depending on the thing thats in there's condition. I'll get some photo's up shortly.

So thoughts turn as they do to making it go faster hur hur hur! Without making a nail bomb, looking at maybe a mild port and polish although someone over here in the west to actually do it seems a little thin, and it has been suggest the P3 cam the go to hot up cam for Guzzi's. Only I was under the impression, not ever to be confused with fact that the P3 actually detunes 1100 Sports some power will be regained as we've obviously got a bit of blowby on the rings.

Do you have any recommendations for a head man or lady on the east coast and a cam it mainly does country runs so we can sacrifice some round town pleasantries not that it really had any to begin with.

It was hard for me to understand your post but I think what you are asking for is mikerichmotorsports .com

I gotta ask: What's a "side plate" on a Spot?

Sport cam is virtually identical to the P3/B10. I'd be spending money on suspension.

When I read the OPs post, the only thing I can find that resembles "side plate" is the "slide plate" that went "om nom nom into the cylinder".
Not that I know what it is, but it sure sounds scary ! :o

Once the slides wear they will eventually snap off the leading edge of the slide. Pod filters don't help.

Ooooh.  The slide plate in the carb broke and was sucked into the engine.  Ouch!

We've already had a pretty good go at the suspension short of doing a complete fork swap and trying to fit some lighter wheels. I am aware of Mike Riches services but I'm trying to keep parts of my bike less well traveled than I am.

Kinda the opposite IME, saw it once or twice on LM 1/2 with unfiltered "bird catchers" but even then you'd have to have criminal neglect to actually keep riding with slide that worn.
Pod (unifilter foam) filters work well, I've used them for over 20 years on my own bike, I do change slides with atomizers and needles maybe every 50K miles, usually cos I can tell by fuel consumption that they're due but like new tyres, bike suddenly back to perfect running.
Only ever a slight ridge on slide you can just feel with fingernail. in the bin for that

So Murray
Just fix what's worn, with new slides, needles and atomisers it will be like new, you'll wonder how you rode it like that.
They are a maintenance item, yours should have gone in the bin years ago,
