Ignitions there are several and I think its really up to the guys budget. Look up pics of Harley drag bikes from the 70s and 80s. I was thinking I could use torque cones, like I've used on Evo's before. And if you sell the bike to one of our visitors, we will not charge you any commission. Tools Needed To Rebuild Ironhead Aside from basic hand tools, you'll need a piston ring installer, torque wrench, dial caliper, feeler gauge, and quite a few specialty tools.

A few months back I aquired a 74 ironhead sporty for a rediculous price. But like Atom said get the basics solid before you bump it up. Headlight works Hi-Low , Taillight works, Horn works - Brake light not working. Repairing the lower end requires specialty tools and skills, and can take considerable time to properly measure and rebuild. In the 72 and later trans failure was usually due to guys trying to hop the motor and not sorting out the old trans that has been hammered on for the past 20 to 50 years. I cant tell you how many times I have seen guys buy the best money can buy to put in their motors.

Ironhead Engine Build

The overhead-valve engine had a horsepower rating of 40, marginally faster than the K's 38 horsepower, with engine compression of 7. I definitely want to start with some mild head work, but not to mild. The big thing with these is that you can just drop em in with stock springs and such. There is nothing like an old Ironhead for peeling the pavement off the road. In 1985,Harley-Davidson replaced the Ironhead engine in its Sportster motorcycles with the Evolution engine, but for many bikers, the Ironhead is the very essence of cruiser motorcycles. I want to surprise and maybe even spank a few loud mouths big dollar chops with a budget built ironhead. Bike is in good condition, but it is almost 40 years old.

What is it you want the bike to do. Some side to side play is normal and actually needed for when the engine gets hot and metals expand. I removed the engine from the frame and after installing the weld on kit and had the frame powder coated semi gloss black. The side cases are in great condition. The 1977 was possibly a better built model as Harley struggled to rectify the catastrophic quality control of the 1971 to 1973 years, and also didn't have the problem of the unsplined gearshift lever shaft. I have listed this bike for sale, though I am considering a cosmetic restoration on it to raise its value. I know what I can do to improve performance and at what cost.

No at least for me Is it loud? The motor is so primitive, you can hear everything going on inside of it, if something doesn't sound right, shut it off, and figure it out! I want the person doing the work to take their time and do a good job. Through its lifespan from 1957 to 1986, the Ironhead powered many different styles of Sportsters. Check Bottom End Play After the cylinder jugs are removed, check the connecting rods for up and down play. On the built stuff I always find they get the job done. Powder coat is almost done. A few things that would be helpful to answer your questions 1. It was made in several configurations including 883 cc, 1000 cc, and 750 cc.

ironhead performance impossible?

The parts can be but building one is like playing Russian roullette with a fully loaded revolver lol. Prices do not include shipping. Transmission pulls and shifts great! Bikes older than that tend to be getting real hard to find parts for, although I have been known to work on old 45 Flatheads and K Models. I have never heard this and i was just about to order a ultima single fire unit for mine. In 1974 the Motor Company switched from right to left, although you shouldn't be surprised to see a 1974 Sportster with right foot shift.

That's probably a 1973 model delivered and registered in 1974. Because no two engine builds are alike, you won't know what tools and skills you'll need until a complete disassembly and careful inspection of parts. Had not thought about the transmission. New battery, new oil, new filter, new ignition switch and keys, new transmission oil, new front master cylinder rebuild kit installed. Many of the special tools needed can be fabricated. From 1929 through 1951 Harley-Davidson produced a series of motorcycles featuring V-twin engines with 45 cubic inch, or 750 cc, displacement.

New chrome hand controls and levers and black Biltwell grips. With overhead valves and a higher rpm, it was able to achieve more power, torque and an increased cruising speed. Always seems strange to me though. Each old bike is one of a kind and will be treated in accordance with its special needs. Not very much hwy riding if any. It has a fresh paint job, I just rebuilt the custom carb and changed out the fuel lines. You can do everything to them.

Engine cases are the most important component of an Ironhead engine rebuild. As long as you aren't dumb, you won't fuck up the motor any more than you would ripping the piss out of it stock i. This engine was made by Harley-Davidson from 1957 until 1985 and it was used primarily in the Harley-Davidson Sportster. It is retarded from where you will want to run it. The Harley-Davidson Ironhead motor is the main reason for the enduring success of the Sportster. Antique accents like Gas primer cups, Gas Tank syringe, and Glass reader gauges exemplify an early century motorcycle but are not required for operation.

How do you get your bike done? Cams I use only Andrews Cams unless I send the stock P cams out of the motor to them for a regrind. The rear end including rear fender, tailight, and License plate bracket are all hinged and open to the side to allow for rear tire replacement when necessary! If you swap your cam cover out with a new one, or change your cams, always check the clearance. It may be prudent to do a complete engine rebuild from the flywheels up. There are two big negatives for first-time Sportster engine builders. Tach and Spedo fogged, but I'll fix that before it sells.
