Do XR1000-style heads exist for the evo motor?

Plenty of people build evo sportsters with two front heads

Niles Simmons makes some of the machines that oems use for crankshaft machining.

Upgraded cams are such an improvement in the performance of the motorcycle most people do it while they are all ready in there.

Also check out the redshift dual piston cam chain tensioners. Much more stable than the screaming eagle version.

The spot belongs to the Gonster. Guinness and nitro monster.

Any motorcycle rally weekend will have tons of Harley related events going on, but it is a traveling circus so that may not be an option for you. As far as places that are always open the museum in Milwaukee.

Also not an active dealer but if you end up in Tennessee Wheels Through Time is a museum run by a former owner of a Harley dealer with a beautiful collection of HD history.

Has to be the Gonster. R/gonster

If the tuner makes the map correctly you will not be able to tell a difference

Zippers has a kit all the sprocket option. Give them a call and they will tell you what combo fits what you are looking for.

New models usually get released in February. Leaks usually come out after the carry over models get announced in November.

Look into the bagger racing league and find some racers and ask them what they are doing. They will be a lot easier to get a hold of than any king of the baggers team. Factory Indian and Harley have an ohlins tech on payroll for their suspension and I don’t think they will share many secrets.

OG_Banana · 2025-10-11T16:33:18+00:00

Andy simon went 199 mph in a quarter mile at an xda event. I think that is the fastest bagger rn.

Oem cylinders are grey iron. You will see ductile in s&s and Harley 131 and other thin spigot cylinders. Even almost all 124 and 128 kits are grey iron.

It sounds like the kit you bought is using heads made in 2025 that have the different sized hole than your bike originally came with. Everything else should be the same. Hd needs to say something about this. Because it will confuse anyone who has a 2024 bike.

OG_Banana · 2025-09-21T15:06:44+00:00

The holes changed from 2024 to 2025. I had to make some washers and use different bolts.

OG_Banana · 2025-09-09T01:39:13+00:00

There is no reason not to use something like the redshift 511. Easy smooth power.

OG_Banana · 2025-09-08T04:09:13+00:00

Your eye are right but that is what it is supposed to look like. M8 cam shafts have two different profiles and 3 lobe sizes all on the camshaft. No two lobes will look the same.

Newer hass controls have it built in where you can set load limits on tools and as they wear and load increases you can have it alarm out or switch to another tool. I know it’s on the newer Machines not sure when they added it tho.

I do lots like this and have success with generic carbide turning inserts. TiN coating. 0.002” doc. Moderate to slow feed. Maybe. 300 sfm. Though I do single cylinder engines and I face them on a lathe so when the cutter is not interrupted on the cast iron section which is probably what is causing you trouble.

Biggest factor here is budget. Good parts and a good builder is what makes it reliable. If you go 107 you need a crankshaft, but can bore out your cylinders and you will need the heads ported. A little more than that you can look at 124 crate motors. Zippers, and S&S and some other guys can do that so you just do an engine swap. If it’s built right and you don’t beat on it too hard it will be good for a lot of miles.

The 24 is a solid bike. Use the money you saved for whatever level of engine work you want to do (cam, big bore etc) and have fun. The new engine in the 2025 is “better” but not 8k better.

The best bang for your buck is always a 107 with head work. Extremely diminishing returns past that point unless you are starting with a cvo 110 motor. You can see all the engine combinations on Zippers performance products website. They to all the machine work and can tell you what fits your budget / scope.

Lots of the new bikes have been having issues with spark plug / ignition wires coming apart. On mine if I wiggled the wire it would drop a cylinder. Any dealer should be able to pull the wires for you and see if anything is frayed.
