You probably ought to go ahead and take a good long ride today and it may be your last opportunity for some time!!!
Actually, with all the help you'll get here and on the RSR
you won't have any problems. I'll give you a tip that may save you some grief. When you're fooling with the needle clips and springs, etc. get you a large, clear plastic bag and do your work inside that bag. That way, when you drop a spring, clip or whatever, you won't have far to look!
I think you'll really be pleased with the performance boost and looks when you get everthing sorted out. I have the BAK
with 102 cu in on it and love it.
