Castrol GTX for motorcycles
I hesitate to post anything oil related since there are endless threads and it seems to be a sore subject with some. But for anyone interested, Castrol, which I've run in everything for the last 40 years, has a non synthetic 10w40 designed for bikes and wet clutches. I got it at Autozone for $4.99/qt. The synthetic was $9.99 so I left it with them. Changed the oil and rode about 30 miles. I have to say the shifting seemed much smoother and the clunk I usually hear when changing gears is much less noticeable. Also, the noise I usually hear from the clutch when its cold wasn't there. I know we like to think everything we do results in improvement but I think I've found the oil I'll use in the Vulcan.
Many or most of you may already be familiar with the product but I didn't know it existed until I went to the Castrol website. I hope maybe this will help some of the newbies who still aren't sure which oil to use.
