So im curious what do people think buy the harley 135 crate motor for 8k or have a builder do big bore heads basically do every thing but the crank and rods. Im definatly torn my bike has a 131 big bore done already. I was planning on doing heads and some other things this winter. Bike makes 137hp 160ftlbs now builder said with work planned should see 160+hp and 170ish ftlbs. Ok so then yesterday he post on his facebook 18 road glide with 135se crate only thing done was D&D exhuast and there tune. Bike makes 160 169 on dyno. So it got my wheels turning I could have reltively same power and torque plus a 2 year warrenty. Now im not sure what to do. Can anyone chime in with there thoughts. I have to be making a descion soon i need to get the bike to them and get parts on the way. Thanks for your time

The dyno run is from the first build done before i bought the bike 1500 miles on build.
The first invoice is from the first build
The 2nd invoice is what i plan on doing






Curent dyno run shorty pipe is holding the motor back

First part of the build before i bought the bike

What i plan to do this winter. Plus i added the D&D and got rin of the shorty

 

I call BS on 160/169 out of a stock 135" crate engine. More like 130/hp and low 140/torque.
Stick to your plan and build your own up. Their are 128s that make way more power than a 135" crate engine.

SE 135" crate engine performance

 

This is from the builders page. Not trying to argue this is just what they shared. do you have any suggestions for the build i have planned? Im torn on doing plate and pump breathers builder says i dont need it if i dont want it. Im not worry about money but dont want to just throw it away. Hell i put a darkhorse in it if i should and its worth the cost. Anyway thanks for chiming in.


Just finished tuning a HD 2018 Roadglide Special, Harley SE 135" crate engine, with Power Vision. Has a D&D 2 into 1 exhaust with big bore baffle. 160hp and 168tq. Very impressive combo.

 

Seriously. I'm not sure what his 135" is but it's NOT a stock SE crate 135". You are on he right track to a 160/170 build. No need to start over with an $8000 135" crate engine and stick a fee thousand more in it besides to get 160/170.
the maxcell camshaft you have listed or what you have now doesn't tell me much as to what it is in terms of IVO/IVC of it which is important to know as is the compression your 131" BB kit is at.
As for what's holding you back at this point I'm sure the exhaust is but also know a 2in1 isn't necessarily needed either unless you prefer jt. The heads are too at this point.
Also I don't care what anyone says a 3 stage pump and plate is not a bad idea especially if you run higher rpms. The latest HD pump can and has sumped.
I know exactly what I would do in your case and I'm doing it to a 128" this off season and expect to be pushing closer to160/160 with it.

 

I'll ask Jake Tuesday if there is anything else done to it. So would you do the breather kit? At what HP & Torque should i be concerned with the crank? Im also on the fence about doing clutch basket as well builder says stock is fine but just curious on what others think. As of now only doing clutch pack. Any other things i should consider. I just want a bike that is bulletproof motor with solid power and can go on long rides thinking 6k miles a year

This is my first harley build so just not sure. I had big power built for my 38 fountain but never in a bike outside of lame *** tire shreader kit.

motor **** my blown 540s making 875hp 925ftlbs spinning at 6400 on 7lbs of boost the motors are built for 1100 hp but want to just enjoy them and not beat on them.

 

I'm with gunner on those crate 135 numbers...complete bullshit sales tactics. Fuelmoto has a stock 131 or 135 on their site, cant remember which, but its around 135tq 130hp. How is the shop you posted getting 30 more of each out of the "same" motor? Ding ding ding...we have a winner...you are correct...theyre not. Moral of the story is just because it's written on a piece of paper doesn't mean it's true. Find an honest independent builder and build your own. Obviously money is no object so a warranty shouldn't be a concern either.

 

Sweet fk'n boat btw!. Kick *** blowers. I've been putting blowers like that on truck chassis along with vacuum pump bodies. The craziness some guys go to just to pump out ********. lol.
One of them blew the belt in pieces after just 3 minutes at 2500 rpm.

 

this is a independent builder. I’ve talked to them multiple times on the phone. They have spend at least 2hrs on the phone with me just about the previous owners build. Not even thinking I was gonna take the build further I hadn’t even bought the bike yet. I’m not sure why they would lie. They build motors I would think they would want to do that then use crate motors. The crate motors are tuned with Harley tuner this bike was not tuned with a Harley tune.

I’m gonna ask Jake what they did to get those numbers.

very nice. Yeah building these motors Gets spendy quick. But they are built right and built for 1100 hp there easily 400hr motors with proper maintenance.

Fingers crossed I don’t blow a belt like that. I’m only running 7lbs of boost on 91+ I do mix 50/50 with 100LL.

 

You know you already have most of the parts to have the 135 if you already have the 131. All you would have to buy is the new crank and intake manifold injector pistons and piston ring

 

What are the specs on your cam?

Your afr readings look off to me, looks like its inclosed loop, it should really not flat line like that. I'd shoot for something near 14-14.5. You didn't mention if you upgraded injectors or not either.

I fully expect my little 114 with cam, manifold, injectors and header to pull near 130hp. Maybe I'm dreaming but the FM website shows they can do it.
