running poorly

hi

today on the way to work on me 99 curvy she started to cough and splutter like it was out of fuel! so i got to the hard shoulder quick and stopped but it kept running so i just gave it a hugh hand full just to push any crap blocking the jets flush through and after that is seemed to be ok but it now backfires quite a bit with hugh bangs!

and on the way home it feels a bit hesitant i was in 5 and the bike would not go past 7000 rpm! and slowly starts to dip in revs but it dos want to cut out!

i had the tank and airbox off the other day sorting my choke out! how can i make sure the airbox is back on properly? also where do the two hoses from the left of airbox go?

help needed

many thanks

You did the chokes?So they are not sticking and the cables are free.Could be an air leak where the airbox hasnt sealed properly back on the carbs,or the two pipes you mention.They sound like the crankcase breathers which should be attached to the crankcases.

yep the choke is all done

thanks for the advice i'll check all the other hoses tomorrow,

Someone has mentioned about the foam under the tank coming loose and blocking the air intake? Is this maybe happening?

Sounds like it's running too rich. Have a look at the plugs. Could be as simple as a sticky choke.

It's not the SV's old party trick of misfiring due to moisture in the plug top is it?

not the choke thats all sorted out now, i'll check the air box tonight the two hoses off the left of the air box i have 1 long tube wich goes to the engine and i have a shorter tube wich just hangs off the airbox does that sound right?

cheers

No you have 2 pipes which go to the engine on the LHS. One front right which just dangles off with a stopper in the end.

yep i found a loose pipe on the engine connected it back on and it rev'd past 8500k so hopefully it should be all ok i'll test her tomorrow
