[QUOTE="Thomas H., post: 181009, member: 9748"] [USER=7183]@cjpayne[/USER] and [USER=5]@racerx[/USER] - The bike is a model that was imported to Denmark in 1973, ST-50, also known as the Dax, so yes, it has a slightly different shift pattern. Thanks for your suggestions regarding checking for a potential leak, I'll have to do that soon. I actually noticed that there was a bit of fuel leaking from yet another place, see the attached picture. I did however try to quickly check the float adjustment (didn't see any signs of fuel inside the float), made it cut off the fuel a bit sooner, but didn't change anything. Issue still remains; when I've been driving for a longer trip, I see this small amount of fuel leaking in the following 2-4 days, and then it stops once again after a while. I also feel that the bike has a harder time keeping the engine running when I slow down my pace, for an example in order to stop. Might also indicate that there is still getting too much fuel to the carburetor perhaps? Anyhow, reckon I'll still have to test the float as suggested by you. [USER=3972]@kirrbby[/USER] [USER=7183]@cjpayne[/USER] funny that you mention this kirrbby, I wasn't really aware when I finally had assembled the bike. Assembled everything from scratch, except for the engine that is. I thought I could just switch gear by pushing the lever down, boy was I surprised ;) Both managed to make several engine brakes, and get it to do a wheelie changing to the 2. gear ;-) cjpaye, the engine ought to be in good condition. Several things were changed during the second time where I had one take a closer look at it, also related to the gears, since it had a hard time shifting to begin with. I think all should be good now in this regard however. If you scroll all the way down to the bottom on this site, you can see the box with all parts that were changed.. So at least hope all is good, but don't know it of course. [URL]http://mechmania.net/2019/06/12/1-year-later/[/URL] Hoping that kirrbby is on to something with the shifting technique, since this would (perhaps) be the easiest to cure. I've had no gear machine before, so no practice, only from a car. I see you say that the clutch disengages when the RPM's drops, and allows for a smooth shift. Does this mean, that it's actually normal, that I can't make it shift from 1st gear (1 up) and to Neutral (1 down from 1st gear), right after I've let go of the throttle? Second gear on this bike is 2 down from 1st gear, meaning that it has to go through Neutral first, before I can get it in second gear. It is however not possible to do as soon as I releases the throttle, unless RPM is already quite low before releasing it - but after a while it is.. As soon as it drops in RPM.. Meaning that all of this is perfectly normal, and that it ain't about that I can't switch gears at certain speeds, but more that I can't switch gears immediately after having released the throttle? Sorry if it sounded confusing, just trying to figure out what's normal here and what's not, since I've never had a machine like this, - but I appreciate all the help you can give me. You mention that it's not easy to get it in neutral, - maybe easiest when stopped and in idle. But I need to get it in Neutral right, - in order to go from 1st gear to 2nd? I've attached a sheet from the user manual, - how it shows that the gears should be changed as well. BTW; I've tried adjusting the clutch, no real changes here in this regard. Makes me believe even more that it's just me, and not the bike... Sorry for these rookie questions guys! I owe a round ;) [IMG]http://mechmania.net/Pics/Inked20190714_191150_LI.jpg[/IMG] [ATTACH=full]62438[/ATTACH] [/QUOTE]
