Hey forum, I'd like to know if anyone has had this problem before with your bike. Just got my bike back from the shop where they cleaned and sync my carbs as well as some other maintenance stuff. Yesterday I went on a short ride, about 8 miles, to see how it felt. Everything went great. 30 minutes later, I was going to take it back out and whe I went to start it, and it didn't want to start. I had twist the trottle to full just to get it started. Once started it sounded like it was struggling. I cranked on the throttle several times to see if it would clean up but it didn't. Put it in 1st gear and it would just bog down. Temp yesterday was 90 degrees and sunny. Any ideals what may have caused this?

 

Vacuum hose loose/ripped/detached somewhere? Serious leak somewhere? If you can get it started get it running and shoot short bursts of starter fluid to the general direction of the carbs, if the revs shoot up you got a vacuum leak somewhere. Don`t go nuts on the stuff though, if applied enough it can damage rubber parts, short bursts evaporate quickly and don`t cause any hazard. IMO if you`ve just got the bike back from a shop, it`s the shop`s worry to suss it out as it is more than likely something they bodged/forgot to tighten.

Just a thought, could it be a loose plug hat? spray some water onto the exhaust manifold and see if it vapors off all four pipes.

 

Matti is correct. I'd take it back to the shop. If they are reputable, they will honor their work and get it sorted out. In addition to all the things he said, it could be that they didn't get the carbs completely cleaned out and something was floating around in there that became lodged.

 

Thanks for the advice forum fam! Oddly enough, rode it again today and sid the same route as the day before. Got back home and let it sit for about 30 minutes. Started it up and it was the same start up.....run switch to run, ignition switch on, hit the starter and the stater would just turn until I gave it some throttle. It started up but it sounded funny. Racked the throttle a few times, put it in first and it sounded like it was missing. By the time I got to 2nd it sounded normal again. Got to a buddy of mines house and stayed there maybe 45 minutes. When I left his house it did the same thing

 

And did U find out the cause?
