i changed the chain and sprockets last year on my 82 750. i did some research and went down 3 teeth on the rear. made a big difference on the highway and mpg. always seemed to be revving high in top gear, 6000 rpm for 70 mph, now its around 5000rpm. i went with a good o-ring chain.

Went out to check the chain and realized it's not only loose (~2" play), but the label on the swing arm is already saying I'm just now in the "replace" phase and I haven't tightened. Yikes! Ok, so I've scanned through the backlogs of this list, and it seems like everyone says get a good chain, but I have *no* idea how to compare manufacturers. Just called CycleGear and they want $130 for the chain, and $40 each for the sprockets, so almost $250 for the set after tax. (ouch!) EBay has this set for $109.95: http://cgi.ebay.com/ebaymotors/HONDA-CB750-CB-750-NIGHTHAWK-O-RING-CHAIN-SPROCKET-_W0QQcmdZViewItemQQhashZitem3a4ee6122fQQitemZ250431803951QQptZMotorcyclesQ5fPartsQ5fAccessories And this set for $132: http://cgi.ebay.com/ebaymotors/HONDA-CB750-Nighthawk-91-03-O-Ring-Chain-Sprocket-Kit-_W0QQcmdZViewItemQQhashZitem35b17f162fQQitemZ230611162671QQptZMotorcyclesQ5fPartsQ5fAccessories And this set for $139: http://cgi.ebay.com/ebaymotors/Chain-sprocket-kit-Honda-CB750-NIGHTHAWK-91-03-_W0QQcmdZViewItemQQhashZitem41585a0b2aQQitemZ280655170346QQptZMotorcyclesQ5fPartsQ5fAccessories I have no idea how to compare them. They are also stock. I was considering going to a 16 T front sprocket described here: http://www.pipeline.com/~randyo/16_Tooth_Sprocket_Mod.htm And it *sounds* like I keep the rear at stock 38T and the chain stays at stock 525-110 even though the front sprocket goes up from stock 15T to 16T. Question 1: Do I need a different size chain if I go with the 16T front sprocket? Question 2: Has anyone here done the 16T switch? I'm excited by the lower highway RPMs, but I'm worried I'll lose acceleration and torque at the low speeds, and I do a lot of curves here through the redwoods in 2nd and 3rd gear. Any recommendations on if this is worth trying? Question 2: How do I compare chains? Question 3: Where have you bought chains & sprockets from recently that you would recommend for high-quality, and quick shipping? Question 4: How unsafe is it to ride the chain in the "replace" zone while I wait for the new chain to arrive?
