The 103 To 117 Big Bore Kit – Is It Worth It?

Among Harley Davidson aficionados, a passionate debate continues to rage on the possibility of transforming an engine’s capacity from 103 cubic inches to 117 through big bore conversion. Such alteration could potentially deliver noteworthy increments in power and performance; yet carries several understandable difficulties and restrictions.

Main Issue #1 with the 103 to 117 big bore kit – Cost

Although a 103 to 117 big bore kit can give your Harley Davidson more power, the hefty price tag associated with it may be off-putting for many riders. Not only are new pistons, cylinder heads and camshafts pricey on their own, but you’ll also need to factor in labor costs for installation as well. This combination of high parts and installation fees makes this type of upgrade out of reach for some Harley fans.

Potential To Damage The Engine

When you opt for a 103 to 117 big bore kit conversion, the enlarged engine displacement can place intense pressure on the internal components, leading to premature wear and tear. Not only that, but it also intensifies stress levels on your transmission and drivetrain components – making them more prone to breakdowns or costly repairs. So if you go ahead with this modification, be sure you are prepared for any possible issues that may arise!

Why Do The Upgrade?

Despite the possible difficulties, many Harley Davidson owners prefer to execute a 103 to 117 big bore kit conversion. The main explanation for this is that the standard engine size of most touring models -103 cubic inches- can feel lacking in power by some riders. A117 cubic inch motor, however, brings an inspiring surge in torque and performance which leads to an altogether more thrilling ride experience for those willing brave it!

Several aftermarket companies offer kits that make the 103 to 117 big bore kit conversion far more convenient and cost-effective for Harley owners. These comprehensive packages come with all of the necessary components such as pistons, cylinder heads, and camshafts plus an easy-to-follow installation guide.

It’s essential to understand that a 103-117 big bore conversion is highly intricate and not something done in a few simple steps. It necessitates extensive technical expertise, specific tools, and the right equipment. Therefore, it’s advised to hire an experienced professional with a demonstrated track record for this job.

Is it better to just buy a 117 instead?

The decision of whether to buy a new 117 engine or undergo the labor-intensive 103 to 117 big bore kit conversion depends on numerous factors, including part and labor costs and the cost of purchasing an entirely new engine.

Converting your engine to a 103-117 big bore can be costly with both parts and labor costs steadily increasing. Furthermore, there is also the potential of causing irreparable harm to your engine during the alteration process – resulting in costly repairs.

On the contrary, buying a 117 engine can be an expensive endeavour depending on the motorcycle model and its availability in the market.

Comparing the cost of both options and evaluating their advantages and disadvantages is a wise approach before making any decisions. Additionally, it’s essential to consider the resale value when it comes to motorcycles – as adding 103 to 117 big bore kit conversions may not be as attractive for potential buyers as having a factory-built 117 engine from day one.

Generally, if the cost of converting your bike and purchasing a 117 engine are comparable, you may want to consider doing the conversion for its value. But in cases where the cost is significantly more than buying a new motorbike with a 117 engine already installed, it would be far more economical to just purchase one from the start.

My Opinion On The Conversion

From experience, if the costs are close, and even if the 117 is slightly more expensive, I would personally save myself all the trouble of going through the conversion process and just buy the 117 new. The only caveat to this would be if I already own a 103 and have customized it to my tastes already.

Conclusion

All things considered, a 103 to 117 big bore kit on Harley Davidson bikes is not without its hurdles and restrictions. Though the potential increase in power can be appealing to many Harley owners, it’s also crucial to take into account the cost associated with this alteration as well as the possibility of engine damage. As such, prior to making any decisions regarding this project, carefully review both its benefits and drawbacks while keeping price points in mind – preferably enlisting an experienced professional for help!
