Rough Riding

[boyallie]

I have a Kewlmetal Air box...Hindle exhaust...and a Juice Box. Hindle went on about 2500 miles ago. VERY rough running when accelerating at around 3500 to 4000 rpms..or around 50-60 then it smooths out. Hesitates in that range....kind of sputters....answers?

What was the last thing you added, the Hindle, JB? Make sure that you have settings 5 and 6 on the JB different and about 2 settings apart otherwise some of us are getting what you describe [stumbling or cutting out at full throttle in that rpm range].

Hmmmm

The Hindle was the last thing changed. I tried to enrich the mixture on the JB but I couldn't get any changes to stick. I tried to enriching...(yellow?)but the instructions I have and what the JB was actually doing are two different things. Is it running too lean? I didn't install the JB or Hindle and purchased bike used. However, I know for a fact that the Hindle was put on right before I took the bike.

To set the JB, while idling push the mode button quickly to adjust the 5 settings[#1 is fixed]. If your not quick it will go back to the beginning. I have the following settings with mine: #2=3,#3=4,#4=4,#5=1.5,#6=3.5. Since you bought it used I recommend calling a dealer and see if they would look up to see if your Spyder[vin#] has had all recalls done. If it was me I would remove the JB if you can't get it to work or if it does then set it to zero's and take it to a dealer for a performance check.

Interestingly, I reset the JB to stock...then pulled the negative wire off the battery terminal for an hour....hooked up the tupperware and now it rides better than it ever has. Go figure.
