Description

Details

Retains the factory side panels for a classy, original look with all the benefits of Mikuni VM carburetors.

Breathe new life into your Honda CB450 twin with this high-performance Mikuni carburetor conversion kit. You can toss those leaky old Kehins, because this kit offers quicker starts, rapid throttle response and a better top end utilizing the legendary Mikuni VM32 – the choice of racers and custom bike builders worldwide.

This is the only conversion kit currently available utilizing billet, CNC-machined manifolds specifically designed for the CB450. The stock manifolds on the CB have always been a problem. The rubber breaks down and cracks, causing air leaks, leading to a lean condition that can rapidly destroy your engine. Some folks try to use CB350 manifolds for their conversions but they just won’t work. Not only are they the wrong size, they create numerous clearance problems with the petcocks, cross over tube and side panels. Our beautiful billet aluminum manifolds solve all these problems. When mated with the VM32 and our heavy-duty rubber adapters, this kit will provide years of dependable, trouble-free service.

This kit will fit Honda CB450 K1 models (1968-74) and CB500T models 1975-76.

What this kit includes:

  • (2) custom jetted VM32 left and right Genuine Mikuni carburetors
  • Left and right billet, custom-designed manifolds
  • Manifold gaskets
  • (2) Heavy duty, long-life rubber manifold adapters
  • (4) Hose clamps for manifold adapters
  • (4) Hose clamps for fuel line
  • 30”of heavy duty fuel line
  • (2) Manifold base gaskets
  • DIY cable kit.  Requires assembly
  • (4) 6mm stainless steel button head screws
  • Fine tuning jet assortment
  • Two tapered American made air filters with hose clamps

Questions & Answers

  • Do you sell the kit without the carburetors?
    If so, how much?
    thank you

    I'm sorry, but we do not sell the manifolds/gaskets and hardware without the carburetors. However, if you have purchased a this kit from us in the past, we can sell replacement parts.

  • I just received this kit in the mail. I thought the cable supposed to be fully assembled, but the cable that was sent with my kit requires me to cut and solder the ends myself. Did I receive the right cable?

    We used to have the cables custom made, but our cable manufacturer has been unable to keep up with our demand, so we had to find another solution. Our listing does say the kit includes a "DIY cable. Requires assembly." Our photo in the listing shows an assembled cable, so we're going to change that to a photo of the unassembled DIY cable kit.
    We are sorry if this caused you any confusion.
    I have provided a link from my website on soldering cables. If you have any questions, please feel free to contact me at rick@nichecycle.com

  • Would these fit an 1983 CM450? only concerned of billet manifolds and my frame design. Stock frame btw

    We have never attempted to fit these on the CM450, but it is a completely different frame and head design from the CB450, so I doubt it would fit. We do not sell the manifolds separately from the kit.
