These are really hard to get to 330, most people hear 310 and they think ESR 310/330, but Hondas have a 72mm stroke. Its a common incorrect crossover. There is/was no KIT for a Lt. They used Early tecate and Honda Sleeves, and just made them work. I've only seen 2 true 310 that I didn't personally spec and build, Ive found pistons for half a dozen others. Im telling you the old stuff are really are not a great setup, extremely thin sleeves at 74mm max bore, no one really took the time to make a real sleeve for the LT that offered a KIT, it was a off the shelf and live with it to keep them cheap. Im not saying there are no good or real ones, they are just not from the big box stores and are FAR and FEW between.
