Just curious to why Kawi suggests valve inspection/adjustments at intervals half that of the other major Japanese manufacturers?

For my '00 ZX-6R the service manual states inspection/adjustment every 12,000km while the 600cc counterparts from Suzuki/Honda/Yamaha get 24,000km between having their inspection/adjustment.

All of the bikes use a shim under bucket system, and I would assume the top end of each to be relatively similar, so why the difference? Is Kawi overly cautious?

Opinions/answers?

wow, i didn't know the others were up to 24k. i knew yamaha was 'cause of how light they made the valvetrain for the R6 when it first came out. but kawi, as everyone knows, haven't exactly kept up with the other manufacturers at making their bikes as "cutting edge"... :( personally, it doesn't phase me one bit.

My ZR is supposed to be done every 6000 miles (9678km) but I round it off and check them every 10000 miles (16129) so far at the last check (30000m/48387km) no adjustment have been needed.
I suspect the engineers put the engines through a battery of test and the earliest they could get a valve to fall out of adjustment is where they set the check interval.

I just had mine done and after a little over 10K miles, they were still good....and my bike is old (technology-wise).

Forgive & forget. Just never forget when I forgive.

Like ThirdNinja's, my 1995 ZX-9R just had her valves checked at the end of last season, with a tad over 10K (miles) on the clock. Everything was still well within specs.

yeah guys, that's a good point. often you find when you go to adjust 'em... they're still well within spec. and that's usually the "rule" as opposed to the "exception". :) i love desmos too, but jap bikes ain't no ducati that's for sure...!!! LOL the I4's (all brands, kawi included) are way more rugged.

regarding shamer's post - since 1996 the 6r has been undefeated in EVERY final round of EVERY 600SS ama/prostar drag race. electroplated bores,12.8:1 compression,K-TRIC,formula 1 type coils,4-2-1 header,hexagonal extruded swingarm,uni trak and 46mm tubes,ama 600 champ, fim 600 champ,prostar 600 champ. sounds pretty cutting edge to me.

I've been good...just busy...waiting for warm spring weather, along with the rest of the unfortunate Midwest people who don't have year-round riding weather! LOL
