I see a few other looking for these, as I will be, as I take care of the more immediate stuff at hand.
If you change over to these, do you end up re-jetting, or having to retune the carbs? Would be good fo know before hand.
I'm sure it has been discussed at some point here over the years, but has there ever been a group by on these when there are several that want these.
I did not have to re- jet when I was using my Cobras. Bike ran just fine no loss of power. However it did run a bit rich until I went to a K&N air filter.
