Motorcycle Repair: spark plug, plug colors, spark plug

Question
hi.front spark plug burns light dark.and the back one burns white on the strap grand.is that ok?thanks

Answer
If you are talking about a harley, the front cylinder stays a little cooler than the rear. If you can have slightly different plug colors because one cylinder may burn a little less oil. It doenst really hurt anything
Good luck and happy riding
