OK here goes.
Had a problem with the plug wires just coming apart then crappy plugs.
So when I put the new coils go to start it and it would only run on full choke, when I backed off it would back fire.
It was already late and the V&H full exhaust it too loud at 11PM.
Pulled the plugs for like the 5th time and found 1/2 has some carbon 3/4 had the same but were wet. Then it hit me 3/4 were in switched. put everything back together and I was riding.

Now the problem is when I'm riding I find in that in the lower RPM range (1 to 3k) it feels a little rough, but when I give it a little more throttle it revs nice and smooth.

I haven't done anything to the bike and all I know about what it has is the full exhaust.

It's a 92 katana 600

Check your plug gaps and check your grounds on the coils.

plug gaps are everything. double check em

OK got new plugs to put in yesterday, just have to knock off some of the honey-do list before I can work on the bike.

went for a spin yesterday and it felt horrible doing turns from a full stop.
had to use some serious clutch control to get enough power to get through the turn.

I believe the gap is set at .025 where should it be???

I believe your plugs are supposed to be at .035 but you will need to double check that with a phone call to the stealer.

If you've replaced your coils, wires and plugs and you have a rough idle, how are your carbs? Here are a few things that can go wrong.......

- Gummed slides or partially clogged pilot jets can cause that problem.
- A vacume leak could also cause rough idle but would have a slow return to idle after letting off the gas.
- Carbs that are out of synch can cause rough idle
- If you have an ignition advancer in there it may also cause a rough idle too. That's the sacrifice.....rough idle but better mid range.

I haven't had a chance to work on the bike, but it idles fine.
I can rev it all day standing still without a problem.
It's under load that it acts up. It's like as soon as I let off of the clutch I have to gice it more throtttle than I use to. It feels like on a turbo when the boost kicks in, from no power to wohooo hang on.

Wohooo
Changed the plugs and set the correct gap and it revs smooth.

Took it for a test drive to get an new headlight bulb. The PO had on of those crap blue bulbs and I couldn't see at night.
