Get a set of gauges and do it yourself. "There is a certain satisfaction in knowing what's going on in between your legs."

Here's a pic of the gauges I use. They work great. Be careful about buying a cheap set of gauges. I had a set and they were not at all accurate. Ed

650ed brings it to the point, good tools save money and save yourself trouble.
As I always say, buy cheap buy twice
my set of sync gauges made in Germany

do you have a source with prices for sale on those nice lookin gauges? friends have multicylinders bikes, may come in handy...

The idle issue isn't really an issue anymore...I Had the old KZ out n about today for awhile and she was very well behaved. So maybe what worked on my single cylinder jap bikes thru the decades works for my inline four also...a little bit of seafoam and run the balls off it for a few tanks of gas...she's gettin' about' 25 MPG lately..and I changed the oil n filter, judging by what came out, it was due, black...The KZ sitting with my sons Helix, which has been a very reliable mount for him, always starts n goes, the small wheels makes it kind of squirrelly for me to ride, no gears, just nail it n go...
