Hi Purple
I'm 190#'s , 5'10" , and have a long legged Sportster for my second bike with my S-40 being #1 bike. I rode my S-40 over 800 miles in one day last April with no issue . Mostly cruising the super slab at 75 or 80 mph. getting 48-50 mpg. Running along at 55 mph I get about 55 - 58 mpg.
I ride around with my CMA buddies on long rides (They all have monster bikes , two of them have goldwings ) ... on any road besides the interstate I can leave them at my will --- and on the interstate I keep-up just fine .
YOUR HUSBAND WILL HAVE MORE TROUBLE KEEPING UP WITH YOU THAN YOU WILL KEEPING UP WITH HIM !
You can run on any Gas you can fine .
The cam chain thing is no issue till the 15,000 - 18,000 mile neighborhood . Then Its no big deal to fix it for the next 30,000 miles.
The fuel petcock is no problem till your in the 10 year old area , then its a <$20.oo / 1 hr. fix . --- forever more.
We have a buddy in San Antonio , Tx with over 130,000 miles on one of his Savages and still ridding it. He's the one that's got me ready to put an 880 Metzeler tire on the back of mine next time.
I've only got about 65,000 Savage miles now , but I'm still working on it !
