  • Running hard

    Got the bike out for a first ride after repairing and going through the entire bike over the winter, it seemed a little rough until i started beating on it some, winding it almost to the rev limiter it started idling better and just plain run better, is that the nature of this engine? Like you can't just baby the motor you have to brings the revs up occasionally or it starts running crappy, its like the more i beat on it the better it ran, pumping up the lifters maybe, all the bikes I've had over the years were overhead cam engines this is my first pushrod engine on a bike, it so different riding a bike with a low rpm engine but im learning fast and had fun all afternoon on her

      You don't need to beat on it but it hates to be lugged ( low rpm ).

        Below what rpm is considered lugging on these 1700s

          It’s not going to be lugging while loping along at a low RPM while cruising with a light throttle setting. These are LONG STROKE engines that have the mechanical advantage to deliver low end torque.

          ‘Lugging’ is a condition when your brain, left foot and right hand isn’t on the same page.

          You’ve got to think like an automatic transmission!!!

          Anytime, no matter what the RPM is, if the engine is straining to increase your speed, you’re lugging.

          Thats my story, and I’m sticking with it.

            I'm just guessing that your bike had old fuel, or a gummed up carburetor, and as you rode it it started cleaning up.

              Keep in mind that the gas has been in there all winter. once you get fresh gas running thru it things will get better. The lifters pump up after about 5 seconds of running so that has nothing to do with it.

              Duke you were posting my answer as I was typing it. lol

                All's good Dave, I've done the same thing myself.

              Like others have said this engine likes to rev to near the limiter. It has a 5 speed trans but that is not a problem if you use most of the RPM range of the engine.

                Run fresh gas with seafoam treatment through it. Don't need to beat on it at all...should run smooth always if tuned correctly. Gas mileage should also be 38-44 mpg so start checking it that may let you know if there is a tuning issue.

                  I went through the entire bike over the winter the carb was disassembled and cleaned thoroughly, as was the fuel tank, the bike was worked on in my house so the fuel tank was bone dry, and every bit of fuel in the lines and such emptied i even ran carb cleaner through all the fuel lines, for the first tank full i used shell super from a very high volume station , im not used to this engine maybe 6 hours total on the bike so far, but the engine sounds off like it doesn't have the sharp bark in the exhaust like other bikes I've had. The bike is so smooth with the roadwing installed it got away from me a few times , i thought i was doing 45 and the speedo was reading almost 60 where on the 650 if you were going 45 it felt like 60

                    If the engine has stock compression, switch back to Regular.

                  Paul, I can't speak for others, but I've noticed the bike always runs better after a good long ride; especially when I stretch the R*'s legs. I believe it has to do with carbon build up. These bikes, especially the earlier years, are known for carbon build up, so it never hurts to clear things out. Even more so if you're like me and do a lot of around town trips in between long rides. That's why the Seafoam is a good recommendation but nothing beats a good ride.

                    Have to agree 100% with Doc on this one. My Roadstar and XS do not like lots of short rides in city. Very cranky and just want to ride. I try to get them out weekly for at least an hour long ride each and they just feel way better than the short rides to and from work. Take er put for a good ride and don't be afraid to get the lead out sort of speak! Lol

                      They like to be thoroughly warmed up, If you ride it too easy for a long period of time the combustion chambers can carbon up so bumping the limiter occasionally helps keep things clean...
                      not all those who wander are lost......

                        Bumping the limiter can also be fun.

                      8I think the outside temperature being around 50 has a lot to do with it too, I think your right about cleaning out the carbon, the owner before me probably road it too easy, l will keep riding it hard occasionally and let you guys how its doing, which years had the problems with valves sticking and what is the symptom of it when it happens, i went throtle after turning out on the street and it coughed and stalled but i figured the idle was too low or i pushed the choke in too early, with temps at 50 it doesn't warm up so good, it ran real nice coming of the highway when the engine was good and hot

                        Yes lower temps will cause what you are noticing. What grade oil are you using? I was using 20w50 and live in NB Canada and have seen a noticeable difference switching to 10w40. I find in colder weather it was real cold blooded and needed to be warmed up longer. Using to 10w40 does not need as long if not much warming up to run properly. If running in cold temps often I have changed the pilot jet one step up and runs way better in cold weather. Hope this helps out. JC

                      My 2008 fuelie doesn't care about any temperature or elevation! Runs great all the time. Carbonation is the root of all evil!

                        Yeah but if something does go wrong on fuelies good luck finding the problem on the road, most carb problems can be fixed right then and there

                            You can count the fuelie problems on this site on one hand. Problems are a non issue.

                              Most carb bike issues are self inflicted tinkeritis issues as far as performance. Other issues such as electrical have been refined over the years but even some of those are from people that shouldn't own a pair of wire cutters and electrical tape.

                            i sold my XS, got tired of kicking it. there were 4 XS 650 chopper bobbers at tropical Willie's tattoo show in daytona this year, and a rare find, a post WWII ural engine in a choppa, noone could ID it, heads look weird. i got pix............
