Ok.. so it was right after I warmed her up for about twelve minutes *it is very cold here* I was leaving my driveway and it occured that my helmet was not strapped.. so I pulled over on the other side of the road and while in gear put the stand down before I put her in neutral, which killed the engine.. it just started tbhis long 'hiss' sound, kind of like what a small fire sounds like (for about 7-8 seconds straight I would say).. but no smoke, no metal against metal, no odd smells or leaks.. I don't know if this is normal. I am a first year rider. I just got my bike completly checked over and a full tune up professionally. So I strapped up my helmet, put her back in neutral and turned her on, she was fine.. idle was normal, started right up, everything was ok. Decided to whip her around the block a few times then come back to the driveway to shut her down and see if the hiss happened again.. it didn't. I am confused. I tried to google it a bit and couldn't find the problem anywhere.. I even then turned her on and then puposely put the kickstand down while in gear, no sound.. she gos right to sleep without so much as a purr. Ah, talk about being a new rider and being over sensitive with your baby.. Any ideas?
