Jet kit?

its not dynojet but has anyone heard anything about the company?

According to authorities, a good-running gen2 benefits not much from jetkits unless many other mods are in place aNd may require some carb tuning to get back to running as well as stock. If someone can find dyno data the matter would be settled. Typically, a tuned jetkit on most bikes would lift the curves a certain percent. To optimize it you'd need dyno time and a few runs. A couple of washers and turning a screw might get you to the same place.

Twenty-four years after owning my first VFR, i'm still practicing my riding to the point where i think i need more hp.

 

so jet kits are just crap?

 

For the most part. Unless there is other work done like exhaust,cams, bore changes or unrestricted air cleaner (may be). If you have the correct A/F ratio now, what's a jet kit going to do? No offense but unless you really really know carbs and the proper way to read plugs (not the porcelain) with unleaded fuel most guys end up screwing up the A/F ratio. If you have a dyno or a lot of track time (drag strip) there's no real way to tell what has been done with the A/F and the power curve.

That's why they state each kit is different depending on what has been done to the motor/bike.

 

Squirrel and Grey have sound advice, more grief than power to be gained.

 

this one time I jetted this crappy ass bike I had it ran okay for a few weeks then I was forever tinkering with it... some folks swear by re-jetting after they put on an after market exhaust, but I have never "had" to re-jet

 

I believe the reason a jetkit doesn't help a gen2 is due to the very well-tuned and refined setup that the bike had from the factory. Can't improve on perfection, eh ??

I've seen needles from a gen2 VFR Dynojet kit, and unlike the gradual taper of stock needles, they have very abrupt steps along their length, with maybe 3 different diameters.

 

If your stock needles were wore out and you weren't sure if the jets in the bike were stock or drilled, do you think a dynojet kit stage 1 would make for a good set of replacement parts?

I think the dynojet kits are about $110 for 4 needles and 8 jets (4 114's and 4 118's)

The oem needles are hard to find, but I found some for $17 each and oem jets are $7 each. So the same number of oem parts is slightly more at $125 or so.

 

Spend the extra $15 on the OEM stuff and save $$$ in headaches later trying to figure out a good A/F ratio with a jet kit. JMO
