There are the numbers for my K8 I recorded before I installed sliders.
RPM........Speedo (km/mph)
5K...........72/45
6K...........87/54
7K.........103/64
8K.........118/73
Relatively flat road, wind speed less than 10 kph, 170 lbs. in the saddle, and laminar lip installed.
Speeds are what was indicated on the speedometer which has a 10% error when compared to GPS.Are those indicated or actual (via a GPS, corrected speedometer, etc) speeds? They look like actual...
No, it improved very slightly as the engine was running more efficiently in the area of revs the engine is used most. Suzuki also, I believe, remapped her from what I can see to take advantage of the higher revs. There is a different power curve and output on the dyno when I compare the earlier 2007+ machines and the newer 2010 models.Interesting, did fuel mileage drop on the post '10 machines?
My 2008 is almost exactly the same. I have a 7% error on the speedo. I get around 70 mpg when running relatively flat 2 lanes at 50-55 mph actual and high 50's mpg when running 70-75 mph actual on the expressway. (I sure get tired of having to add "actual" and "indicated" to a post.)my bike gets worse mileage at high speeds on the hiway... around 58 at 80 indicated... at 55 indicated it gets about 70 mpg... i ride about half and half... 13 miles hiway, and 13 miles 2 lane... average about 60-62... speedo is 10% off/high... odo is only 5% high tho... fastest i've gone is 100 indicated (90 actual) at 9000 rpms...
Mine's a 2003 and I'm not sure how wide my belt is. I bought it used with 29k miles a couple weeks back. Can we get the new style rings for the older 385 cc engines? Aftermarket perhaps?whalley, what year is yours? Amongst other things, Suzuki changed the final drive gearing (lowered it) and engine specs from early 2010 onwards. To compensate for the lower gearing and maintain the bikes top speed, the piston was redesigned to take a heavier duty, wider top compression ring to prevent piston flutter at high rpm and to help transfer more heat to the bore. This meant the engine redline could be safely raised to 8,950rpm instead of 8,500rpm, thus maintaining the bikes top speed with the lower overall gearing. The idea was to improve performance and help lighten the load on the CVT and clutch.
