I recently just got married and as a wedding gift my dad gave me his 2006 883 Sportster that's been sitting untouched for 11 years. I'm doing a thorough cleanup of the engine, carb, etc. The throttle grip is oily and deteriorating and makes your hands sticky and black so replacing that as well. Also going to put. Marvel mystery oil into the cylinders and do a full cleanup of that just to make sure nothing is seized before I try turning it over. While looking up parts the obvious thing is every site asks what model you have. Using the 5th and 6th numbers of my Vin (CA) I have determined that the bike is an XLH not an XL. Looking for certain parts XLH is never an option. I've read in other discussions that in the older days the H stood for higher compression. What does the H mean in newer-ish bikes? When ordering parts do I just use the standard XL 883 version?
