Staling out I have ar 100 rt. This is my first bike. I have been loving it until recently when i started having problems. I can crank it and let it warm up and then try to go and it still stalls. What happens is that i put it in first and my rpms go up to about 3500 but the engine doesn't rev up. I can play with the choke sometimes and finally get it to go but other times it just dies out. As of last week i couldn't get it to even move more than the inch i would roll it myself. We don't have a motorcycle shop anywhere close either so any help would be appreciated. Thanks.

May 19, 2013 - the brake failure warning is flashing. Pull in the clutch and firmly press the start button until the engine starts. Did the light go off?

Most dealer's have archived owner's manuals kept by their service departments for reference.
Restoration, Custom builders and parts suppliers have detailed parts lists and most include torque spec's for products they sell. I recently built a bobber, and Dime City cycles, Old Bike Barn and Blue Collar Bobbers were most helpful on wiring and torque spec's
As are machine shops and fabricators.

maybe an air leak from vacuum side on motor breather pipe

There are some fuses under the seat area at the back of the bike, but doubtful that this is the problem. You did check the "kill" switch on the handlebars?

More likely old stale gas in the fuel pump and filter/pressure regulator. Try cranking the bike with the starter and hold the throttle open slightly to get some of the stale gas out of the injector and associated fuel line.

I had one of these bikes as a demo at the BMW dealer that I worked at and it was a great machine.... Hope you can get out on yours more often.

try recharging the batery first then check charging system i think its not charging the battery or the battery is a dud one

Are you sure it has no spark or are assuming that because it cranks and wont start?? It may just be stale gas if you have spark. Personally, IF it really has no spark before I tried anything else I 'd charge the battery. Some bikes are EXTREMELY intolerant of low voltage levels and while you may have enough juice to turn it over, it may not have enough to run the coils,ignitors,etc. . It ran when you put the new battery in so that tells me its more than likely OK otherwise and the battery may have simply discharged a tad from sitting and now cranking it. Trickle charge it (2 amp) overnight and try it again.

I love my R1150RT. It is smooth, it has a lot more lug at lower RPM than the older modles (2003 and before models with 1 spark plug). The modifications with 2 spark plugs have cured all the surging. Should you want a smooth, reliable, comfortable and high speed touring bike, I would sauggest this bike is the best.

Could be your timing chains are very loose, they will make a noise on start up. Also, when was the last time you adjusted the valves? If they are way out of adjustment, ( on the lose side) they will make some noise.
