Service details for a suzuki gsx1400 oilcooled engine

I think you mean a VS1400 or a VS1400GLP. I don't think there is a GSX1400. Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

First, check and , if needed, change the spark plug(s), and oil. Always use the stock spark plug for your particular bike. Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Change the oil filter if your bike has one. Changing the oil acts as the "filter" in bikes that don’t have an actual filter. Lubricate the chain. Lubricate the control cables with liquid graphite, ( Lock Eze ). Make sure the tires have adequate pressure. Check the spokes and snug up any that are lose. Aim the headlight and check all functions of the bike, kill switches, brakes, etc.

How about a top rating on this solution? Thanks!

GSX 1400 all years requires 4.8 ltr of 10-40 semi synthetic oil with oil filter and 4.2 ltr without oil filter every year or every 5000 miles change the plugs only if you have a missfire of something rhe plugs are useually ok for a good 15000 miles
