backfiring means you have an air leak or a lean mixture. Look for leaks at the header pipes or perhaps a crack in the exhaust.
Cold air getting into the exhaust is usually what causes the backfire noise.
You may have a lean engine running situation but the bike would have other issues besides the backfire.
Let me know if you are having any other issues or if it just the backfire.

Should be behind one of your sidecovers. I f you did'nt get a manual w/yor bike then order one from your dealer. It's an invaluable tool....Good luck to you friend....Tim

hi,if iremeber the drain plug for the sump is at the rear of the motor and is a horizontal one,so watch it when the oil comes out it goes a long way and makes alot of mess on the floor,i cant remember the quantity of oil to go back in,but about 3ltrs springs to mind,there is a sight glass on the right hand rear of the r/h engine casing so you can get it dead right,dont use a fully synthetic oil,the clutch will not like it and will start to slip,and for the life of me i cant remember where the oil filter is,although i normally only replace the filter every second oil change anyway,check with your local dealer to find the location of the filter..nice bike though i had a 1500lc and did over 50000mls on it trouble free,look after it and you will have a good run out of it for years..cheers
