Thanks, the information it's helpfull. I searched online and found my notations for the 650 Triumph race bike on Brit Bike....Yeah, I don't keep track of stuff. Anyways, Triumph 650 has a 6.5 inch rod with a big end similar in size to a LG A10. R&R Triumph rod is 415 grams, Map says their A10 rod is 440 grams..I know additional weight can be compensated with proper balancing, but I believe less weight is always better for vibes....I hate decisions, lol
