Just wondering if I could get any help. I opened my engine up for the first time after having the head re-shaped by a reputable two stroke engine builder here in NZ. The squish angle is cut to 14 degrees which is about what is recommended in the online posts that I've seen, but the width is only cut to 9.5mm which seems a little narrow compared to what I've seen on other lt500r builds that I've seen. Are there any gurus on here that could tell me if that sounds like it's within the ballpark of where it should be? I realize it's probably a wee bit of an open question, but from what I've seen most heads are cut to around 13mm of squish band width which I would have thought was a significant difference.
My motor is an '87 and it has a 40mm carb and boyesen reeds, though I'd like to run a 44mm carb and a vf2 block in the future. The squish is set to 1.1mm, it has 195 degrees of exhaust port duration, an AAEN pipe, a kfx450r air filter with a custom air box, 88.5mm bore and it's all been freshly rebuilt. It's being built as a dune quad so I want it to make good torque higher up in the rpm range
Thanks for any help
