Well, apparently the bike now does 95mph at 7k rpm in 5th gear.
Had a harley guy I met on sunday run around the 495 beltway with me so I could find out. Fun fun fun...
:twisted:

I just noticed this post from a couple of weeks ago. The 850 won't do 140 unless you have made some radical, radical changes to the transmission gearing. Unlike the chain drive bikes which can change sprockets, The shaft drive machines are locked into ther rpm-to-mph ratio. The 850 runs a true 60 mph at 4460 rpm. That is an almost perfect (4500 being perfect) 3 to 4 factor to relate the two. Divide the rpm by three and multiply the result by 4 (and mark off a couple of decimal places) to get your speed. ex: 6000 rpm divided by 3 = 2000; 2000 x 4 = 8000 or 80 miles per hour.7000 RPM in 5th gear on my GS850GLZ. I think that's about 140 MPH.
7000 rpm would calc out to a hair under 95 mph. The highest measured speed from any of the magazine roadtests when they were new machines was 124 mph. All of the quarter mile times were in the high twelves.Believe in truth. To abandon fact is to abandon freedom.
Nature bats last.

Nah, it was the fastest speed I could go. The fuel bowls are apparently almost totally drained of incoming fuel at that point. There is either a restriction at the in-line fuel filter or the floats need to be raised or something. I know this bike has more to give but at 95 mph it starts to suck the bowls dry, I can hear the carbs sucking when I reach that point. The sound of the pods changes to kinda like when you suck on a straw to get the last bits of soda out of a cup. :?Originally posted by robinjoWas that the fatest speed he could keep up with?Originally posted by Detman101

Fast enough !
"When we were young and dumb" Yeah I did it. GS1100EZ. Barely broke in. Long stretch of country road. Roll that throttle back and hang on. Tried that once 20 years later and the engine wanted to but the frame and suspension said forget it. Major speed wobbles !Comment

Had my GS1100 to 220 Km/h just the other day with a little more yet to go (in a closed course situation of course) 8)Comment

167mph??? We had over 250hp and ran a 9.0 for those mph's..10.80's with a good 60 ft' maybe 125 mph...Was your 167mph on your 10.80 pass?EULC ONComment

no , my 1/4 mile speed was 132mph, 167mph was on road top gear approx. 10000rpm. Would go faster with different gearing.
