Harley Davidson Engine Power Won't Destroy Fuel Economy & Longevity

Рет қаралды 19,914

Күн бұрын

The biggest concern with adding power to a Harley Davidson engine is will it hurt longevity and fuel economy, when done right it can increase both. There are limits to what a stock Harley Davidson engine crankshaft can handle but it's more than you might think. In turn putting some power into a Harley Davidson engine makes it more efficient, meaning you're getting more power with less throttle which in turn equals less fuel usage. Performance parts paired together are substantially better than the factory parts, which in turns leads to longer longevity of your Harley Davidson Engine.

I'm an old Panhead guy. I recently picked up a 1996 FLHR-I with only 29k on it from a Brother of mine. It had the obsolete unobtainable parts Magneti- Marelli system on it. It ran so-so and mileage was crappy and the engine wasn't very responsive. I upgraded to a Mikuni HSR42 and an Ultima ignition system. It's like a brand new bike. It's very responsive and runs awesome.

My opinion, you did the best thing you could do with any bike that has a old Mag FI system. Parts are impossible to find, let alone anyone that tune it and messing with it is just asking for trouble. Best thing you can do is convert those to a carb, spend the big bucks and upgrade to a Delphi Efi conversion if you want to keep FI.

@@GixxerFoo I bought the bike after watching your video. I got the idea to go ahead and do it from watching your video "when fuel injection fails it's time for the carb." I figured out an easier way to do it without finding a donor bike harness and parts Etc. Cost about 1200 bucks for all the parts the minor wire harness that I did, but it's a lot cheaper than upgrading to the newer fuel injection system.

The only thing that has really effected my gas mileage is the crappy gas. Holy Mother Of God, gas is so terrible these days. If you can ever find a station with just plain old straight up pure gasoline, you will be SHOCKED at how much better your bike will run... or anything else for that matter.

@GixxerFoo 2 жыл бұрын

That's a fact, it's getting harder and harder to find 100% pure gasoline that's not cut with ethanol. I only run that 10% ethanol if I absolutely have to and even then I have octane booster that's supposed to counteract the negative effects of ethanol.

@peteryeanacopolis2037 2 жыл бұрын

Good point. With today’s gas you might as well add a glass of water to every fill up. I use 100% gasoline at every opportunity even if it means riding a few miles out of my way. The octane rating is usually 90 at those pumps but because it’s REAL gas then that won’t matter however a splash of Lucas octane booster solves that concern with ethanol infused gas and it REALLY helps with 100% gas. There’s a noticeable improvement in how my bike runs with real gas with respect to a quieter, cooler as well as a more responsive throttle on my 117 big bore kit.

@hawkdsl 2 жыл бұрын

There are a couple stations 30 miles from me that still have 100% gas. They are usually in route of my rides, so it's a win win. Sadly, we will never see corn gas ended. But that's another story.

Fuel mileage went to 44 mpg at 65 to 70 mph. If I keep the speed down below 50 mph, I can average 57 mpg to 62 mpg. Bike is running fine now, no more changes until its worn out.

@divine_swine9665 2 жыл бұрын

Excellent advice Foo! I’m not a tech, just of a “weekend warrior” guy who is not afraid to do anything on my bike or a buddies. You hit the nail on the head, adding more power without reinforcements is a roll of the dice. Each engine is different, If 2 identical Lowrider S’s roll out of the factory and they were built back to back/one right after the other, they’re both going to have different characteristics and run differently. 1st bike could have crank runout of 2 thou and the 2nd at 8 thou.. (MoCo, in their infinite wisdom, changed runout tolerances after too many recalls… they went from .003 to .012 🙄). If all things are equal at 30k miles, same riding style, same maint, same parts, etc, etc… and both wanted to change cams and install gear drive cams, I’d advise against gear drive on the 2nd one even though MoCo says they’re within spec. Adding power to an already “lopsided” crank is only gonna make you get to catastrophe sooner rather than later.

@GixxerFoo 2 жыл бұрын

That is so very true and I've said that for years, no two engines are ever alike! Gears are an awesome upgrade, but I really steer away from them on a stock crank just as the miles pile up. I like to see a Timken conversion with a built crank before going with gears. It reduces a lot of the risk of catastrophic failure.

On your advice... I wanted to change my '17 oil pump. For the labor price I should replace the cam plate and probably change the cam. Well it's gonna be down for a while maybe new jugs... I ended up getting a 124 built (from 107). During my Iron Butt Challenges my 107 could get 175 miles a tank on those 85 mph+, high RPM miles. I expressed my concern about that to my builder and he said the same thing you said in your video. If I can keep my right wrist calm it'll be the same if not better. 05/13/22 set out for Iron Butt 48 States in less than10 days. My Ultra Limited preformed flawlessly and when I want to pass, I just roll on the throttle, it's everything I ever wanted my bike be like. Over 10,000 miles since my build and I can say, if you can do, DO IT!

I just recently upgraded my 2020 iron 883 to a ‘21 model Low Rider S which of course has the M8 114 in it. 👍😃. Anyway, I’m in the process of getting a good stage 1 on it. Probably the 636 breather from DK customs with an EBS (which I’ve already done a homemade EBS with stuff from Lowe’s and Ace hardware and a drill) and some slip ons. Beyond that, I really don’t think I’ll do much to this engine? Maybe a cam down the road? Maybe? It runs so good straight out of the box that I don’t want to mess with it too much. I certainly don’t want to hurt reliability. That’s my main concern. Most of what I’ll do after my stage 1 is going to be centered around “cooling” the engine or keeping it as cool as possible. That’s probably my main concern with these air cooled engine designs is keeping it cool, not hp numbers. I don’t have $$$ to burn and want my original engine to last as long as possible!

You'll be alright adding a cam if the bike has good compression, it's always a risk with anything mechanical but if you take the proper steps you'll be good to go with a bolt in.

Bolt in cams usually don't have any clearance issues, I still check the case clearance anyhow and I haven't ever found any base circle issues with a bolt in cam clearing the cases. But still don't blindly put one in without checking cause that will the one time it doesn't clear lol. I'm in central Oklahoma where the weather is wild and you never know what you're gonna get lol. You're pinion runout you absolutely don't want to be over .003" at a maximum for a gear drive cam system. That's a pretty good plan with a race cam plate and oil pump too.

Yeah the M8 doesn't run rich it all, it runs just as lean as the Twin Cam did but it handles it a lot better with the dual plugs and 4 valve heads. The poor Twin Cam was virtually on the edge of melting with the two valve head trying to pull those AFR's.

More power and torque = more heat to dissapate, more stress on other components like valve springs, clutch, clutch basket, transmission. You cannot upgrade the top engine without upgrading other components...not upgrading these other components will bite you big time. Don't worry about fuel economy...worry about increased stresses on other components and engine heat management (consider getting a fan assisted oil cooler)

@GixxerFoo 2 жыл бұрын

Always a huge fan of oil coolers, you can't go wrong there. You do put a little more stress on the lower end in theory, but if you keep it mild with bolt in cams that work with the stock springs you're pretty good. Now if you get into high lift cams and heavy springs you start to put some stress down on the stock parts.

@Bostonterrier97 2 жыл бұрын

@@GixxerFoo This is true...why do I push for lower engine? It's because the lower engine is like a foundation to build upon, and the quality of that future build is dependent upon the quality and strength of that foundation. Now it is entirely true that an owner can add some power and torque and the stock components will do just fine, however it comes at a cost of sacrificing some reliability..components will wear out a little faster. However for those who are very serious and have the financial resources...starting with the lower engine and blue printing it, and putting in Timken Bearings, and forged connecting rods (Carillo) and having that new crankshaft assembly balanced to have as little vibration as possible (I know...part of the Harley "experience" for backseaters is that the bike is a 2 wheeled vibrator and that's why women love them so much...besides the bad boy image of the bike owner...but I digress...)...reducing the vibration (like reducing heat) translates into components lasting longer and having less wear and staying in alignment longer. So...once the lower engine work is done...the Harley owner can then shift their gaze to Gear Driven CAMs which allow for more precise valve timing, and a more efficient OIL pump and better CAM plate (like S&S)...more lubrication = less friction = less wear = less heat = greater reliability. A solid lower end means not only better reliability...but a solid foundation on which the owner can make all kinds of changes to the upper end and still have an incredibly solid bike. It's like...if you're going to want to someday have an engine that produces more torque..you are going to want to have a better clutch and transmission so the owner might want to think about a Baker Transmission. Pricey yes...but very solid. Just like it costs money for performance..it costs money for reliability. A bike owner can cycle through a lot of bikes over time, or can focus on having one bike for a very long time and making that bike as solid as possible.

That honestly seems to make a difference on the Twin Cam factory cranks lol. I got a little information on that surprisingly, talked to a guy who was there when they started pressing those cranks. Part of their cost saving measures was running the hydraulic fluid in the machines longer, they found the dirtier/older the fluid was the cranks ended up with more run out. If you got a crank that was pressed/lubed properly with the clean fluid during the pressing operation they ended up straighter and more true.
