k&n air filter, again
- I was going to install the k&n pod filters but chickened out. So, I
ordered the k&n (TB-9095) filter that fits in the stock box. I have
the off road pipes, dyna jet needle with the clip on the 2nd
posistion (I think)and the oem jets. I think that I turned the screws
out 2.5 turns. I live near the cost of NC, I don't know what the
altitude is. I still get a little popping when I let off the
throttle. What results have the others had with similar set up with
the k&n filter. Should I change jetting? Just don't want to have to
pull the carbs/ air box several times to get it right.

and occasional, I really wouldn't worry about it.
That having been said, to my mind the easiest way to check your
mixture is to do a series of test runs and, at the end of each test
run, pop your plugs and look at them. At the end of each run, pull in
the clutch, kill the engine, and coast to a stop. To test the pilot
mixture, run at about 1/4 throttle for about 30 seconds. To test for
proper needle height, run at about 1/2 throttle. To test the main
jets, run at full throttle. When reading the plugs, a white insulator
indicates a mixture that is too lean, a light tan or pink is just
right, and dark brown or black is too rich.
While it's a sequential process (check your pilots, then needles, then
mains) and it does take some time to do the test runs, most of the
time you only have to change one or two settings to get dialed in. In
my experience it's amazing (given a properly operating carburetor) how
well a bike setup using this relatively easy and straightforward
process will run.
- Hi guys,
Just wanted to let you all know that I mailed some photos from this
group to Shawn at TriumphRat.net to post on his site.
hope that's cool. they were such good photos that I thought they
should be propogated.
