Two questions here. Recently purchased a 99' Vulcan and am conteplating replacing the battery. Not because it doesn't turn over the engine or sounds weak, but more because it is now 5 years old. I plan on taking some long road trips this summer and would not want to be left stranded. On average, how many years should I expect to get from a bike battery?
Also, given the age (but only 3k on odometer) I decided to change the spark plugs. The manual calls for NGK DPR5EA-9 but all that any place carries is the DPR6EA-9. My Kawasaki dealer says that he is unable to order the DPR5EA-9 and that I should use the colder plug. I imagine that its NGK that no longer makes the plug. What are the consequences of using the colder plug. I put them in and the bike seems to run fine but I wonder if all the gas is being burned as it should and also if my performance could be affected. Any comments are welcome. Thks.
