Hi everyone!
I have recently picked up a 2007 SM610 with 8500kms on it and it has been a blast to ride. However it does have a few weird things going on, most of which I am taking care of weekend by weekend. But I am coming up stumped with starting the thing...
Starting the bike cold, with neither the choke nor the hot start pulled out, no throttle, the bike will maybe start and if it does, sputter and die. Fair enough.
Same thing, but with the choke pulled out, it starts, and will happily idle for about 45 seconds, then start losing revs, then sputter and die. I can keep it alive tickling the throttle until its warm, but think that's not quite the way it's supposed to work.
Using the hot start has a similar effect. The bike starts nicely when its hot, warm even, but cold it seems like it can't be bothered unless I rouse it with the throttle for a couple minutes (the needy baggage...)
Anyway, my first guesses are idle speed set too low, carb's durrrrty, or jetting is "messed up". Won't know for sure without openning things up, but it may or may not have been rejetted for the K&N filter and LV exhaust that are on it.
Any tips or suggestions as to what to look for? I'm a little worried that these may be symptoms of a bigger problem and while mechanically inclined, I haven't spent much time inside a carb.
