I had a set of Wood lifters for a few weeks back when they were fairly new to the market. They sucked big time, never would quiet down, and when the replacement set was received from Wood (that's what took a few weeks) that set was improperly machined and the anti-rotation pins wouldn't seat in the case. The set came with a little note stapled to the instructions that said if you ran into that problem it was due to a case machining error by the MoCo and you should just file the lifters until the pins fit. Needless to say that set went back as well and I just went with a set of Harley "B" lifters to get the bike back on the road. The original lifters fit that case just fine, the first set of defective Wood lifters fit fine, and the last set of Harley lifters fit the same case just fine. I don't appreciate being jerked around or lied to by any company, not just H-D, so my opinion of Wood lifters went in the dumper. Maybe the recent stuff is better, maybe not, I couldn't tell you. But the entire idea of letting the valve train rattle for 30 seconds to 5 minutes after starting a bike that has sat for awhile is pure unadulterated BS, I don't give a chit what Bob Wood says.
IMHO, stick with a known product with a long history of satisfied users (S&S).
