With a Tapermeasure...

Cheers MIke. So that is what the Sine symbol must be about on scientific calculator or is that to do with a sine wave .

To revive old thread. I just received Dynojet kit EU spec for 97-99 bike, and needles are different from pictures posted by Crux and Varastorm. I was quite surprised, because shape of my dynojet needles is totally different from stock.

What version of DJ needles do you have?

My needle:

Wow I've not seen one like that before for the VTR. Looks quite fat in the middle and then tapers off again too. Maybe it's for a Harley It would be worth querying it as it could be a mistake in the packaging.

I just found the mistake, there is mark on the foil DNO227 instead of DNO277, thanks for point. I have to resolve it with the seller ...

We should ask Jackflash if he can turn some needle jets up.

Factory Fro HDJ needle jets are just that, replacements... and they work (way) better than the stock units ever did or ever will..... ask me how I know
