1999 magna. engine starts, idles, runs fine. when clutch is engaged bike accelerates smoothly and runs fine but makes odd banging(?) sound especially when under load. sound is similar to sound made when driveline slack is taken up. any clues as to where to look?

if you rebuilt your carburetors you have made a mistake when you reassembled them a carb must sprsy a fine mist of "dry" fuel into the engine intake your carbs are flooding you need to check your fuel floats , jets and, don't forget to check the power piston circuit and, balance (sync) your carbs on the bike when you're done
your chuch is fine if you did not touch it

Did you do an oil change recently? Sometimes a motor cycles clutch shares the oil with the engine and a different kind of oil then the bike requires will cause the clutch to slip. This happens alot especially if someone switches to some types of synthetic oil when the bike had regular oil before the oil change.

You need to see what voltage is at your battery at an idle, with a meter first.

The carbs may need to be cleaned. Try running seafoam in the tank first and see if that clears some of it up. The slow jets may be plugged up inside the carbs. If the snorkel had been removed from the airbox, it could cause siminlar problems as well. have you changed the spark plugs yet? be sure to check out the Honda Magna forums for more info:

The slow circuit of the carburetor is dirty. Take the carburetor off and remove the slow and main jets. Shoot carburetor cleaner through the jets and through the passageways of the carburetor body to be sure that it is clear. Does the bike die when you pull in the clutch and put it into gear? If it dies when you put it in to gear , you may have clutch plates that are stuck together. Take off the engine side cover, remove the clutch springs, pull out the clutch boss and the clutch plates. Carefully separate the plates, replace any damaged plates, coat the plates with oil and put them back in the same order. This should make the clutch act normally again.
