When trying to supply enough fuel to turbocharged and supercharged Yamaha engines, tuners are having difficulty getting jet sizes big enough to do the job. Thunder Products offers their â€œJumbo Jetsâ€ in sizes up to 200! These main jets are longer so they suck fuel from lower in the float bowl. Also, these longer jets have seven inlets; one at the bottom of the jet and one on each of the six sides of the jet, helping to prevent cavitation. Big engines with big fuel requirements to make big power can benefit from these big jets.
These longer, seven inlet jets have proven to be very effective in rough conditions and extreme inclines on the carbureted 4-strokes as well; RX-1s and Vectors. These jets are also available in the same sizes as the OEM jets, so you can replace the stock jets with the longer, seven inlet jets so they continue to pull fuel in even the most extreme riding conditions.
All of these innovative jets are available from Thunder Products; www.thunderproducts.com or 320-597-2700.
