Hey guys, I've had this build in the works for a while now and my plan is to get it done for spring. It'll be my main all-round ride, city jammer and highway cruiser. It's another chopper, old hardtail frame with a +12 springer. I'm looking for a bit of advice on a few choices for engine performance pieces. I've currently got a NOS set of Wiseco 836 pistons I got from Bill P, my jugs are already bored. I'll be porting the head myself. Got multiple sets of roundtop carbs to choose from so will probably stick with those (w/ breadbox or v-stacks) and spend the rest of my "budget" elsewhere.
So one intake valve guide is chipped from a PO having bent a valve in the past. I've been going back and forth on what to do about it, though I've decided there's no good reason to leave it be if I'm putting time and money into this head. All the valves will be replaced anyway (PO didn't maintain valve lash and they got pretty hammered), so what are your thoughts on going with bigger intake valves or just replacing the one guide and using fresh stock valves? As it's a chopper I'm looking for more low/mid range than top end. So I'm a bit unsure just how far to take my porting and intake valves, as I don't want to lose my low end torque gains.
Also trying to decide on a cam. I've got a new Webcam 41 on the shelf, but since I decided on the Wisecos over the cast cruzinimage 836 kit I'd like to take advantage of the higher CR and valve reliefs. Leaning toward the DP295 based on everything I've heard about it over the years. The power range seems right for my application.
So to sum up: What advice do you fellahs have on specific porting characteristics, intake valve size, and camshaft choice for my application of a hardtail chopper looking for mainly (but not exclusively) low and mid range torquey power on a 10.25:1 836 engine? Thanks in advance!
