Jetting seem odd


Recommended Posts

I have stock cylinders with a dune port.  175 psi compression.  V force IV reeds.  Toomey T5 pipes.  PWK 35mm Air Striker carbs.  Carb mount air cleaners.

My bike guzzles gas and sounds like it is splattering in the 1/8 to 1/4 throttle range.  It's not the ting, ting sound.  Just kinda a splattering sound.  Thing is, it has no hesitation or performance issues.  If I'm idling along and nail the throttle, it is instant response.

My jets are 50 pilot, DCE needle, 140 main and 4.5 slide.

Does that sound right to you.  Doesn't that seem fat on the lower end and lean on the main jet?

The motor was ported and built by Kip at Dune Trash Racing.  I assume he jetted the carbs as well.  Most probably have not heard of Dune Trash Racing. He hasn't been building in 15 or 20 years.  This bike was stored for many years.
