  • Maximizes carburetor performance.
  • Includes step-by-step instructions.
  • Includes jets for both stage 1 and 3.

Stage 1:

Intended for motorcycles with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to allow the use of a well designed aftermarket pipes and stock replacement air filters like K&N. Stage 1 kits are designed to improve throttle response and drivability and in most cases power increases of approximately 5% throughout the entire power range can be achieved.

Stage 3:

Intended for motorcycles with stock or mildly tuned engines using a well designed aftermarket pipe and individual air filters. In most cases power increases of 10 - 15% can be achieved. However, drivability may be compromised particularly with short stroke, high RPM motors. On some modern engine and airbox designs, individual filters and proper jetting offer no performance improvement yet compromise drivability, in such cases stage 3 kits are not available.

Q: Jet sizes equivelent in inches?
1 year 1 month ago
I have an 81 cb 900F that I have tried to jet around a flat spot without loosing top end. Seems as though the answer is a tad bit bigger in the primary circuit. Tried the DJ 074 with the DJ 130 initially with the clip in the center... too much fuel-dies at 6,000-lowered needle ATW down and got top end but terrible dead spot at 6,000. Back to OEM primary jet, middle on clip and bad spot at 3,000. Raised needle ATW up, bad spot gone but it looses it at the upper range 7500 or so...I see you make no smaller jets if I'm seeing the chart right. What I need to know is, is the numbering of your jets arbitrary or does it somehow correlate to the orifice size? If they are in thousandths, and the OEM are also then I need .070 but if what I'm seeing of my jets this size that I already have ( Mercury O/B jets) , they are not..

A: The jets in the kit aren't numbered according to the stock jets. Dynojet jet sizing cannot be referenced by either Kehin or Mikuni jet numbering. Dynojet includes the jets and needles required to make the bike run properly after modifications and includes a jetting guide to help accomplish this.
Q: Does it have the o- rings for the float bowl & the float needles & seats?

A: This is just a jet kit and will not include any items to rebuild the carburetors. If you need the bowl o-rings, needles and seats they can be purchased from the OEM parts section :


There are also aftermarket carb rebuild kits that will include all of the required o-rings and gaskets, needle and seat, and some will even include new jets. Keep in mind the rebuild kits may fit multiple models and it is recommended to verify your jet sizes when installing a rebuild kit as the sizing may vary.
