Technical boys please help

Hi all, I have brought a Husqvarna SM610S 2005 a few months ago and I have had nothing but problems with it :upset:

It keeps backfiring and it will have no pull or power, it's so hard to ride as it is. Sometimes it will backfire loads and be totally unridable and other times it's not so bad.

I have checked the air box, taken apart the carb, checked the petrol tank the pipes and the fuel tap. I have changed the spark plug. Anyone got any ideas what it could be?

Any advice would be appreciated.

See reply to other post

and also you may need to check valve timing in case this has slipped, and also valve clearances. Did any of the above you have done make any difference or none at all?

HUSQVARNA SM 610S 2005

Hi

Dont understand whats going on with the post's here?You say

I have checked the air box, taken apart the carb, checked the petrol tank the pipes and the fuel tap. I have changed the spark plug.

Fair enough,but what did you do?

Did you clean the air filter?,and is it the type that needs re-oiling?

Have you completely changed the fuel(could be contaminated?) you dont say?

You checked the air box?

Has this bike been running like this from the day you got it?or did it start its problems soon after,and had you done anything to the bike yourself?

Try these.

When I checked the carb first time there was a bit of rubber in the float and I took it out and cleaned it with petrol and it seemed to work fine for a few weeks then it started doing the same thing again.

This time I checked the carb and found nothing. In fact it's worse than ever at the moment. I will check the valve timing.

All of the other things I tried made no diffference at all.
Thanks for the reply :wink:

The bike started backfiring about two weeks after I got it (private sale.. I must be insane) the first time we checked the carb it had rubber in the float and the air box had come loose as a result of the backfiring.

This time I have checked the carb for dirt and there was none, I have cleaned the air filter (buying a new one as soon as it's running again) and changed the spark plug.

I have checked the petrol tank as in taken off all pipes and made sure there are no blockages. Taken off the petrol tap, checked the petrol filter for dirt.

I will try a complete fuel change and check the links you have got for me.

Thanks boys :wink:

backfiring

hi all.

i am having a backfiring problem myself. every time u want to push my CG a bit, it backfires when i shut off the throttle. it has been doing this for about 11 months but now i ride with my mate i thought i had better do something. i have done everything that my haynes manual says (only says to check nut tightness at the cylinder).

sorry if it appears that i have hijacked this thread but my computer wont let me create a new one for some reason.

enjoy the sun while it lasts!!!

keep biking!!!

Rubber found in float bowl

Rubber found in float bowl May have came from the float and it might be sinking well sunk. It reaches a certain point were the plastic still floats in the gas but goes up and down much slower causing you to run out of gas breifly.and start back firing then run fine for a bit then do it again . More on bumpy roads . Good Luck
