Finally after fighting with Kaw dealer (they suck) I got the right jet for my carb. #150 main---installed new jet and re attached dial a jet and did my best speed yet at top of my test track--32 MPH!!! I again tried dial a jet in all positions and seems to run the same no matter where i dial it in at. Still cant say if dial a jet works or not but I promised myself if I get speed at top of my hill over 30 mph I would quit tinkering. I have a little hesitation off of start and some slight stumble between 1/8 and 1/4 throttle--thinking I am a bit rich with needle(still have needle shimmed with a plastic washer I found laying around)
Also increased my top speed downhill to almost 50 mph!!! Motor is really screaming at this speed.

80 hours on bike and will be switching to synthetic oil in motor and frontend at 100 hours. Maybe another 1 mph faster?? or so??

 

How steep is this hill and how long is it?? What is your top speed on flat ground?? you sound kinda slow.. I do 48 mph on flat ground (aprox 150 yard runway) I have hit 55mph going down aprox a 2% grade.. Infact I should be slower then you with the elevations I ride..

 

32 mph??? Maybe you've over-modded. Ogs 360 ran bot 45 on level ground. Do you have bigger tires? That'll slow ya down and give ya a bad speedo reading. Check the speedo against someone else or a gps unit.
