Anyone Built a Yamaha XJ650 Maxim Bobber? Share Your Tips!

Introduction to the Yamaha XJ650 Maxim Bobber Project

Transforming a Yamaha XJ650 Maxim into a bobber is an exciting project that combines creativity with mechanical skills. Whether you’re a beginner or a seasoned motorcycle enthusiast, this guide provides a comprehensive overview to help you with your build.

Understanding the Bobber Style

Before diving into the project, it’s essential to understand what makes a motorcycle a bobber. The bobber style is characterized by a stripped-down look, often with shorter fenders and a minimalist approach. Removing non-essential parts gives the bike a lighter and more aggressive profile.

Tools and Materials Needed

To modify your Yamaha XJ650 Maxim, you’ll need some basic tools and materials:

  • Basic Tools: Wrenches, screwdrivers, pliers, and a torque wrench.
  • Cutting Tools: Angle grinder or hacksaw for fabricating parts.
  • Welding Equipment: A MIG welder is recommended if you plan to make custom brackets or modifications.
  • Parts: Custom fenders, seats, and handlebars designed for bobber builds.

Step-by-Step Guide

Here’s a step-by-step outline to help guide your project:

  1. Disassembly: Start by removing the existing seat, fenders, and any other components that you plan on replacing or modifying.
  2. Design Your Build: Sketch your desired look for the bobber. Consider the height of the handlebars, the type of seat, and the overall aesthetic you want.
  3. Modify the Frame: Depending on your design, you may need to cut and weld parts of the frame. Be cautious and ensure you’re following safety regulations.
  4. Install New Parts: Replace the existing components with your custom parts. Make sure everything is aligned properly.
  5. Electrical Adjustments: Modify the wiring harness as necessary to accommodate new lights and signals you may want to add.
  6. Final Touches: Paint and finish your motorcycle. This is where you can get creative with color schemes and designs.

Tips for Success

  • Document Your Progress: Take photos throughout your build to document your journey.
  • Seek Advice: Engage with the community. Don’t hesitate to ask questions if you hit a snag during your build.
  • Safety First: Always prioritize safety. Wear protective gear, and ensure your motorcycle is roadworthy before hitting the road.

I’ve been working on my Yamaha XJ650 Maxim Bobber for a few months now. Start by removing the rear fender; it really lightens the look. You’ll want to find a minimalist seat that matches the bobber vibe, too.

Great tip! I modified my fender by using a shorter one, and it fits perfectly. Also, what type of headlight are you all using? I’ve seen some really cool options.

Definitely go for a smaller headlight, mary43! I used a 5.75" round one to give it that classic look. Don’t forget to check your wiring when you swap it out! Any recommendations for handlebars?

I highly suggest drag bars. They really complement the overall aesthetic and make for a comfortable ride once you get used to them! What’s everyone’s favorite seat style?

I’ve opted for a solo seat, keeps things clean and sleek. For mounting, you’ll need a custom bracket. It’s fun to design yourself! Anyone else tried DIY mounts?

I tried, but man, it got tricky! I ended up using some pre-fabricated mounts for simplicity. Do you think they affect the ride quality?

They really shouldn’t affect the ride quality much, just make sure they’re solid. But if you’re worried, Test it out! Just be sure to wear good gear while riding. Has anyone painted their frame yet?

I painted mine matte black and it turned out amazing! But, prepping the surface took a lot of work. Always make sure to choose high-temperature paint if you can. What other customization have you all done?

I’ve swapped out the rear shocks for some shorter ones. It gives a more aggressive stance. Never thought I’d enjoy making mods so much!

Haha, right? Building a bobber can turn into quite the obsession. Anyone felt overwhelmed at any point?

Yes! I had my moments, but those challenges just made the end product even sweeter. Plus, sharing the journey here helps! That’s what forums are for, right?

I’ve just finished my XJ650 bobber, and I think carb tuning is crucial for performance. Upgrading to 34mm carbs made a noticeable difference for me!

Totally agree! I’ve also increased airflow with a K&N filter. Anyone else found specific jets that work well with these carbs?

Consider changing the exhaust too! A 2-into-1 setup can really improve that low-end torque, especially in custom builds.

Great point! I went with a Biltwell exhaust and it has made my bike sound like a beast. How’s everyone dealing with heat from the exhaust?

I’ve actually learned to wrap my pipes with heat-resistant tape. It helps a bit! I’m curious if anyone’s done a full engine rebuild on an XJ650.

Doing an engine rebuild is a big task, but it can be worth it! Just make sure you replace the valve seals—they tend to wear out on these engines.

Good tip! I’ve heard the ignition system can also affect engine performance. Any suggestions for upgrades?

Yes! Upgrading to a Dyna ignition system can smooth out that spark. I noticed a big difference after replacing my old points.
