I also hear the worm cog is longer ? Maybe if I swapped the whole side casing it wouldn't be a problem what do you think ?

Use clear tubing to see it go from the pump to the inlet.

Or turn the engine on, hold the pump open fully, and the bike should SMOKE!

If the inlet side is scored, you can imagine the exhaust port will be worse...

That is bizzare. As I always say, pictures tell a thousand words.

Yeah that's alright mate, you're posting in the right sections so It's not an issue. That's what we're all here for.
