Default Cam selection for my bike

Hi first post to here. Been working on my 2001 sportster lately. Here's what I have stock 883 been converted before I got it to a 1200 with hd cylinders and what appears to be Wisco conversion dished pistons. Has only 7300 miles and 5000 on 1200 kit. Anyway have heads off doing port work doing this myself. I am a experienced mechanic but new to harley world I work on cat equipment. Here's my question is bigger valves such as the kibble white conversion worth it. I opened the seat up and blended it to the port and cleaned he ports up pretty well. I have already did. Valve job on one head with a 30 degree back cut on the valves used kwik way grinder on seats. I have been looking at getting the n8 cams for it. I don't mind fitting different springs and shimming if needed. But are there better cams out there? Bike is going to be a street bike for short trips and fun riding but want all I can get out of it while I have it apart. I M aware of checking piston to valve clearance. Could I use the newer beehive springs with different retainers And locks? Thanks Derek

Ps is it just me or does the stock pushrods look wimpy? On my big block ford pulling truck I would never try running three piece rods at anything over 6,000 I use chrome moly 3/8 one piece I assume this may apply to these bikes as well.

A nice upgrade, that we do to most 86-03 heads that come through the shop, it to switch to the lightweight 7mm stem valves and beehive springs ala the rubber mount bikes. You need new guides of course.



We have the 7mm stem Kibblewhite conversion valves (1.715/1.480), but we also have 1.760/1.530 stainless valves for conversions. These are the biggest sizes we feel comfortable putting int the stock seats. They're a bit shorter than the stock pieces or KPMI's because we generally sink them a fair bit for valve to piston clearance. As you may already be aware, valve to piston clearance is a scarce and valuable commodity when dealing with 883 heads. The net result is a chamber size that's more conducive to a flat top than the reverse dome though.

Anyway, our 7mm valvetrain pieces are available here.

I ordered the n4 cams today. After much thought my wallet just didn't have it in it now for the flat top pistons and bigger valve set up to go along with bigger cams. And they are a proven design. Heads still not done yet almost though. So can i make decent numbers with the set up I have? I,m thinking compression will come in near 10.2 using no base gasket and 0.030 head gasket. Should put piston about 0.002 out of the hole. They are arias pistons not Wisco removed them to clean carbon form them. Std bore dish top 10.2 cc dish smallish valve reliefs. Using screaming eagle ignition and screaming eagle air cleaner, may change or modify that one to get rid of oil puking breather holes in cleaner. Any other suggestions for helping bike out? Thanks

I think you will find that the oem sized 883 valves will end up holding your combination back. I think they will be fine up to a point, not sure exactly where but somewhere in the low 70's you are going to meet resistance in my opinion.

I would expect your set-up to make around low 70s hp at the rear wheel.

So are they a valve sizei could use bigger than stock and use my pistons? About how much is a set of flat top forged. I found the flat top Keith blacks cheap but how good are theyin a performance engine? The arias are good pistons from what I have heard. I used one once in a motorcross bike I had. I will post some pics of the heads I ported soon let you guys see what you think. I can't find a 60 degree cutter for the seat grinder I used at work just the 30 and 45 is all I found its a old kiwk way that used stones. That's one of the reasons I didn't just order bigger valves at first. Is they a attachment y'all know of that I can use to cut that angle? I have not set my build in stone except I have the cams on the way and gasket set. After doin more reading I'm second guessing my stock valve theory. Just have to get my wallet and wife to agree lol.
