I have a Lamberto Collari hand modified Sirio .21 7 port buggy motor with Sirio tuned pipe and header. It's modified by M. Collari. Not yet broken in but it has had 4 tanks so far very rich. You still need to break it in a lot more. I'm willing to let the combo go for $550.00 shipped. If you pick it up its still the same price. I paid over $800.00 for the combo, cost not retail. PM me for more information.
Take Care,
Cheers, Patrick
