I recently had the K&N cone filter, spacer mod with 152.5 main and a dyna screaming eagle II install done on my 97. I noticed I still had some backfiring and some coloring of the new pipe!! I went to the forums for tuning info to see if I could handle the adjustments myself. I found my brass plug had already been removed. I found my screw was only about a turn out. I brought up idle and adjusted slowly, there was not much change in sound but more black smoke the more I turned it out. Not being to mechanically inclined I figured to be safe ask the experts so here I am.
I'm having a hard time finding my sweet spot and need some help. I think my elevation is only around 250m. Anybody at a similar elevation?

My top battery cover was removed in order to get the K&N to fit, now my tool cover only latches down at the key and hangs out at the top. My tool cover is now in my saddlebag to prevent loosing it. Would a little more pressure on the battery allow the cover to go back on with the K&N? I read about removing airbox completely and shifting battery back but not sure I'm ready to go there just yet.

All your opinions and advice are greatly appreciated.

Sincerely

Yonuh thanks but have already been through there. The picture links are all broken. I just did not hear the change when looking for the happy medium between turns in and out. With the screw another half turn out the backfires were still there. I just don't want to mess anything up!!

The pilot circuit is the primary controlling factor for the backfire issues, and the adjusting screw is part of the pilot circuit.  There are several very small passageways involved in the system and they are easily clogged from time, dirt & fuel residue's.  You can try some of the fuel additives which may work if the clogg is small/recent.  Or you can remove the carb and shoot carb cleaner through as many of the passageways as you can find without taking it apart.  If those do not help it to run properly then plan on a complete disassembly and hard core cleaning.
Charlie and I spent part Saturday afternoon and evening (dinner and a stage show     ) redoing his carb and it even worked when we hooked it up afterward !  

Thanks again Yonuh.

Lancer, my carb work was just done a couple weeks ago so if it is due to clogging it will be recent. What do you recommend I try for a fuel additive?
Just to confirm my mix screw is located on the upper right side of the carb towards the engine correct? How many turns are there from all the way in to out?
Only 2 of the 3 washers from your kit were used w/ the 152.5 main and as mentioned my elevation is only around 250m so I was wondering if this was playing a factor??

Anybody have any advice or a solution for my battery and tool cover issue? I really dont want to create any more problems by just jumping in there myself. Not the most confident bike mechanic yet!

Thanks Mort, hope it does not come to all that. As I mentioned, not the most mechanically inclined and it sounds like a major job.

I will try the fuel additive first. Anybody have any recommendations on a good working product out there??

Anybody have any feedback on my K&N and battery cover issue?
