You don't have the factory manual I presume. You'll need one soon. Clymer is like the comic book version of the real thing unfortunately. Dennis...can you help this fella? I really would like to see you get your bike together properly too. I want to hear some great stories this summer about your road trips. I just replaced my starter today, put some fresh gas in, ran some Seafoam through and she runs like she missed the open road! Tomorrow I lube my cables, change the oil and I'm gone. I digress and dream.....
