Running really rich
Posted: Thu Feb 02, 2006 8:16 am
Hey guys for the last couple of months I have had the troble of tuning and getting my YZF705 upto good running standing. Here is a list of what needed to be done:
-Compression was below 90psi on cyl #1 valve clearances checked and corrected and replaced intake valves
-Carbs cleaned out and re-built, using Factory Pro 3.0 kit since I have a K&N pod filters and fully synced
-Floats set @ 14mm found air leak through pilot, changed pilots and stopped hanging up
-played up and down on needles and floats and pilots still running 18-30% (using gas analyzer)
-put back oem needles and jets, still rich
No leaks, strong compression valve clearances checked, running on dyno will only make power higher in the rpm's, but rich as all outdoors. Any one have any ideas??
