Back Fire

[Jboneman]

This is my First GS500 and bike

I have only 164 KM on it but I notice that it back fires sometimes .

I have notice when I first start it up and  sometimes on a down shift it back fires  is this normal or should I take it back to the dealer for them to look at ?

Back firing on shut throttle is semi normal.
Open throttle or steady throttle = lean misfire. That = rejet, most nothing you can do can cure that. Dont take it to dealer for that, DIY, dont buy a DJ kit, but 20/132.5/washer and set it to 3 turns. More details are in the faq/wiki etc. Or search too.
If you have trouble getting those from your dealer, PM me, I sell em in a pack $25 shipped.
Cool.

If it is it a brand new bike then take it back.

Otherwise... check valves (how many clicks on the bike) and tune will need adjusting.

Is it an actual BANG! backfire or a snap crackle and pop on deceleration? If it is the latter it is just after run and normal. If it is the first, you have issues.
