Le Mans 1000 jetting

Le Mans 1000, open bellmouths, 40mm Lanfanconis

Running rich, any comments??
Actually forget “any comments” coz that’s open to abuse, change to: any experience???

How Big did you go on the main jet?

Cant just think if they had an airbox…wheres it rich…?

My Mk V has been fitted with 155 main jets and 70 idle jets since 1989 with Lafranconis and K&N filters (Ian SmaiI/Bristol) and has always performed well. I recently changed to open bell mouths and I fancy it’s a little leaner, which makes sense, and now has a bit of an ‘edge’. (relative term of course!)
When you say it’s running rich, has this suddenly happened?
