A little testing today.
So I went out to the desert today to do a little testing. Ok, it was a good excuse to go out and play but there was a motive to the plan.
I purchased a bunch of bolt on performance stuff and I did not just want to put it all on at the same time and not know what part helped or hurt so I did it one step at a time.
First I drove about a 5 mile course to get some varied terrain with a high speed section to judge the top speed change. All speeds were measured two up with my Lowrance Baja GPS in sandy terrain so traction was never 100% (so your speeds may vary)
Test #1 stock = 45.6
Test #2 Ignition box = 53.6
Test #3 Changed Jetting to 130 and 134 needles in secind clip Fuel screw 2 turns out = 54.0
Test #4 Removed spark arrestor 55.2
Test #5 Slip on exhaust 55.6
Next test will include modifying airbox and richening up the jetting again but I'll save that for another day.
Ignition is worth every penny
Slip on exhaust was not worth the extra noise.
With these mods alone this thing rips and the fun factor was increased substancially
I could barely tell the noise difference between stock and with the sparky removed but the slip on had my ears ringing after the 5 mile loop. I'm going back to stock and waiting for someone to build a quiet system that works. (maybe Muzzy?)
This may be old news but I feel better doing it myself.
