I know there are a million entries on the site on jetting & adjusting carbs, but I am a little frustrated - I have been through many of them, honest!. Though happy to do other work, I am "carb shy" so after fitting following took my '96 LS650 (with 10,000 miles)to local bike store for rejetting -
K & N slot in filter
Hard Krome slash cut muffler
took out snorkle
brand new spark plug - a DPR8EA9
After doing the mods the bike would pop occassionally on shut down (it made no noise with stock filter) and surged a little @ about 30 mph in 3rd (never did that before, either).
I ran it for about 100 miles before I took the bike in, having looked @ the condition of the plug - not a bad color with only a bit of soot - not as dirty as I thought it'd be due to over lean running.
I got it back from the shop with a 150 main, the stock pilot & the fuel screw backed out 2 & 1/3, being told "that makes the pilot size correct" (question - does it?)
I was told it had been worked on before & had "two washers under the clip" which I've never heard mentioned on this site. I was also told filing off the white spacer would make no difference as it "is above the clip"(I had earlier suggested this may need to be done per this site) What does this mean? Everyone on here seems to file away.
I found it still popped a bit so called back - was told to back off fuel screw 1/2 turn but may have to live with it. Still pops a bit & I think overall the smoothness is gone.
So - any advice? I don't want to spend more $$ @ this shop on this job & moreover my friend here with a S40 took his to the Suzuki store & did not feel 100% satisfied. So I will work on it myself now (got place to change out the soft head screws for stainless allen heads - ha!)
Would an iridium (spelling? plug help in anyone's opinion?
Would appreciate feedback with one important thing to NOTE - unlike many of you I am not at or relatively near sea level but 4,200 feet up in the high desert (dry & hot, mild winters). So please take into account altitude, etc if you can when making any advice.
Thanks, George
