Oil Change and Shifting Gears Issues for GZ250?

Hi,





I own 2003 Suzuki GZ250 from last 2 months. I drove around 1500 miles on that. I make oil changes to my car regularly, but when it comes to motorcycle oil change I never did it. The oil looks dirty, so I thought to change oil %26amp; filter. I went to Advance Auto Parts store to look for oil filter %26amp; oil. The closest I found was for “250CC-GS250 (1980-1981)” of Fram filter CH6000 and oil is 10W40.





Can anyone tell me is that Fram CH6000 oil filter is any good for GZ250? And what about 10W40 oil, the manual says use 10W40, any suggestions on that ? Please let me know is there any online website , that you can order oil filters and what that filter model is ? (I live 60 miles north to Atlanta, GA. Any stores around this area? )








Another question is , some times when I shift gears, I feels like it got stuck and I have to slam the gears, does anyone got that problem ?





Is 10W40 oil has impact on how gear system works ? Is there any better oil ?Oil Change and Shifting Gears Issues for GZ250?
A Suzuki GS250 was a 250cc twin; the early 80's GN250 engine is exactly like yours. I don't think there is a replaceable oil filter in the GN/GZ model, but a metal mesh strainer? If it is, you would clean it with gasoline.


I'd use a motorcycle specific engine oil. These little motors don't hold much, and if you spend $10 on oil every 3000 miles, it'll last a long time.


I normally use a 20w-50 oil on any air-cooled engine. If your shifting problem doesn't go away after you replace the oil, check first the clutch free play. If that's okay, you may have some bent shifter forks. Better brush up on the service manual.Oil Change and Shifting Gears Issues for GZ250?
Go with Amsoils motorcycle specific 10w-40.








They most likely have an oil filter for your application as well. Just go to the application guide and plug in your year model and make.

An oil change can make a great difference on how shifting works. Also, go to the dealer, or online for your filter. The engine is claose, but may not be exactly the same. You need to change at least once a year or 3000 miles. 10W40 is fine, 20W50 will work too, although harder to crank in cold weather.
fram are very bad filters cross reference with car filters look under the web sight best oil filters for bikes use purolator or mobil one oil filters if it an outside filter they have the most filter media in them use a non energy conserving oil because the molly that is in the car oil will make your clutch slip use lucas motorcycle oil or amsoil or mobil one or dyno oil shellrotalla t in a blue bottle if it is an inside filter go to the dealer they are the only ones that will have it
