Yamaha FZR1000 Genesis (2GH/2RG 1987) carburettors fitted with standard size 110 main jets amd size 20 pilot/slow-running jets – all ultrasonically cleaned.
Restoring and riding older bikes ourselves, we know how much difference clean carbs make and we’ve been ultrasonically cleaning our own carbs for several years with great results.
Our stock of used carburettors were removed from their donor motorcycles at least 13 years ago (2007 and before) in the days before petrol turned quickly to sludge. We are often amazed at how pristine our carbs appear with their float bowls removed, regardless of how they appear externally.
While we can’t guarantee that our complete banks of ultrasonically cleaned carbs won’t need the usual care and attention (setting up and new seals, etc), if you look at any close-up or open float bowl photos included in our listings you’ll see that you’d be off to a very good start with our carbs and carburettor components!
