1998 with backfire issue
Sounds like a real pain in the posterior. You seem to have a plausible theory to go on.
it is always more difficult to trace back the work/thought pattern of someone whom you don't know.
while it is disappointing to me that I picked up a lemon, it is very satisfying to be able to trouble shoot it down to the root problem, repair and ride again.
I know you obviously have a ton of issues with your engine/bike etc. But i Just cant help thinking that alot of what you said sounds like the issue I had with my bike recently. I was getting alot of backfiring etc. It was mainly in the low and mid range. I had a heavily carboned front plug. What I ultimately found was that the slow jet in the front carb was quite a bit plugged. The bike ran better with a bit of choke etc, but just overall ran like crap.
I have owned this bike for like 6+yrs and put maybee 1k miles on it. I started it up regularly etc., but with what I was going through in life, the bike was fairly much ignored. I just recently got back into the bike, and it didnt take me too long to decide that it was a carb issue. I pulled the carbs, and pulled both low speed jets. Looking at them into the light showed the problem in no uncertain terms. I sprayed the jets with carb cleaner, soaked them, and then hit them with high pressure air, and it didnt do squat. I finally reamed it out with some very fine copper wire, which did the trick. After finishing cleaning it up, and installing te jets, the bike ran like a raped ape. I just dont think these carbs like to sit idle for any length of time. these are some of the biggest carbs ever put on a production bike. Look at your low speed jets just for kicks and giggles.

Have you tried to figure out women?

I have a second hobby that will for this weekend take me away from the bike, however tonight I will be ordering all the needed parts depending on what I find here, someone offered a complete set of heads with valves that would save me a ton of time so i have to check into that, then new cam chains and gaskets, ape cct's and a few misc items like the superbike bar setup i can sneak that in under the wifes radar while i am ordering and buying parts!!
hope to be able to get it back together next week
thanks again everyone for the help!!!
