xs650 Billet Aluminum Intake Manifolods

XS650 Billet Aluminum Intake Manifolds allow fitment of aftermarket 34-36mm Mikuni VM Roundslide carburetors to 1970-1984 Yamaha XS650 and TX650 models.

Get rid of your cracked and leaking rubber intake manifolds and replace them with our super trick CNC machined billet aluminum racing intakes. These are very sturdy and improve flow to your motor. They are perfect when installing aftermarket carbs. Your stock rubber intakes are not designed to support the weight your carbs without your stock airboxes installed, causing them to crack over time. Our aluminum intakes are much stronger and will not crack.

Kit includes stainless steel hoseclamps that will never rust.

These will fit aftermarket 34-36mm Mikuni VM Roundslide Carbs ONLY. Will not fit stock 34mm CV or BS, stock 38mm, or Mikuni 38mm VM Roundslide Carbs.

Sold as a pair.
