Johnie,
I hope you're able to replace those New huge tires on it for stock(3.00x18 Fr. & 3.50x18 Rr. or 90/90x18 fr. & 100/90x18 Rr.)size rubber;those that you have on there will make the bike handle way too slow and then it'll wear out the center only in short order.The IRC tire co. makes a GS11AW in your stock sizes that are excellent.
