A bit of a follow up post to the last one which featured the GSXR throttle body velocity stack kits - several people expressed an interest in aftermarket trumpets for their bike carbs. So in response I can now offer kits for the following:

Carbs....

ZX6R (both Keihin and Mikuni Variants)
ZX7R
ZX9R
ZZR600
ZZR1100
R1

Throttle Bodies.....

GSXR600
GSXR750
GSXR1000
GSXR1300

Stacks are available in 50mm or 90mm lengths. All designs allow a Pipercross style baseplate to be sandwiched below the trumpets if required.

The stack kits are all circa £95. PX600 Filters and pre-cut plates to suit are £100 (add £13 for a compact PX500). Individual Stacks are £15 each and are standard Jenvey/Weber Flange fitment. Available in the following sizes (internal dia x length):

40x50mm
40x90mm
45x50mm
45x90mm
50x50mm
50x90mm

We can also advise on trumpet/spacing/filter combinations to ensure correct fitment:



Free carriage currently offered until end of Sept on any velocity stack purchase.
