Twin Roundslide & CV Carburettors

Our twin carb service brings both carburettors back to peak performance. Both are professionally cleaned, fully rebuilt and bench-synchronised for precise fuel delivery and a crisp throttle response. This service is ideal for parallel twins and mid-range machines, whether a clean, rebuild or full restoration is required, we have a service for you.

Before you upgrade to the “Upgraded DynoJet Rebuild”, please ensure that DynoJet produces the right kit for you. To check if DynoJet supply kits for your motorcycle model and make, please click here.

Please note:

This is a standard cleaning service, we do not disassemble, rebuild or replace components as you would in a rebuild. We require the carbs to be sent disassembled. Unless the rebuild service has been selected, the carbs will be professionally cleaned and returned unassembled. If you require disassembly and rebuild, please opt for the full ultrasonic clean and rebuild service.

Disclaimer:

This is a functional service, not a cosmetic one. Your carbs will be thoroughly cleaned internally and externally but will not come back looking “brand  new” if the existing condition was already poor. Corrosion, discolouration and age-related wear will remain unless you opt for separate cosmetic work. 

If seized mixture screws and jets are encountered, removal is charged at £30 per screw. Due to the precision and time required for safe extraction, this may extend the estimated turnaround time. 

If you are looking for that “factory-fresh” finish, we offer additional cosmetic services or The Showroom Package:

• Vapour Blasting Service
• Stainless steel Nut & Bolt Replacement (Allen Key or JIS)
