Turning A Virago 750 Into A Bobber

I'd previously finished a Virago 535 bobber, so I decided that I'd have a go at its big brother—the Virago 750.

It's a reliable custom cruiser with a lot more grunt than its baby brother, and the shape of the frame makes it an ideal candidate for a bobber conversion.

I found the bike I was looking for, low(ish) miles and fairly decent shape, not running very well, but I was pretty sure it was just a carb issue.

The Original Bike

What I started with

Wheels

I think it always helps if you have an idea of what you want the bike to look like.

I'd seen a bike on a custom forum with a bare metal tank and gold wheels, and loved the contrast, so decided to go after the same look.

I cleaned and masked the tyres up, then sprayed them with etch primer (this is extremely important to get a good bond).

The top coat was done in brass rather than gold as the brass has a duller tone to it which looked nicer in my opinion. I also sprayed the carb tops in the same colour as an extra touch.

Finally, two coats of clear lacquer.

Cutting The Frame

I knew which bobber seat I wanted for the bike, so I ordered this before cutting the rear of the frame.

Once you have mocked up where the seat will go, it's pretty straightforward making the cut in the right place. I made my cut behind the holes for the original indicators as I was going to use the same holes for the new mini-LED ones.

I removed the swing arm and sprayed it black along with the rear of the frame.

I also installed some new 320mm shocks.

Bare Metal Fuel Tank

I removed most of the paint from the tank with some industrial strength paint stripper, and then cleaned it right up with a sandpaper flap disc on a 4" grinder.

I like the brushed-nickel look on metal, so I used some 400 grit wet and dry and sanded long ways along the tank to create the same effect.

The tank looked a bit plain so I decided to add some pinstripes. These were just the rolls of pinstripe you can buy from most auto stores.

Once they were on, I gave the tank three coats of petrol-resistant lacquer.

Pod Filters

The big chrome pod covers at the front of the engine had to go, and I installed a pod filter on the right hand side instead. I had to mess around with the mixture a little to fine tune the bike (after the new exhausts were on) but afterwards I personally think the bike ran much better than it originally did.

Left Hand Side Pod Removal

I have posted a link to the page I used to remove the MIV/AIV system on my bike below.

I was left with a couple of small hoses which I needed to tidy up.

What I did was a bit unconventional, but it worked!

I cut a couple of small pieces of steel tube and taped the hoses and steel tube into a bundle.

I then pushed a piece of larger tube over those. I found a radiator cap that would fit the larger tube, removed the caps pressue valve and replaced it with some metal mesh, and glued it in place.

The result looks pretty tidy.

Making A Virago 750 Bobber Fender

I really wanted to have a go at making the rear fender myself, but eventually decided to go to a metal fabrication shop with the rear wheel and had them make one for me.

The shop did an excellent job and it only took them a morning. They made it from sheet aluminium.

I used 12mm steel tube for the struts, crushed at the ends to create mounting points.

The front of the fender (closest to the engine) was mounted by an "L" shaped bracket directly to the swing arm.

I also put on a pinstripe to line up with the small one on the tank, and then gave it two coats of clear lacquer.

Removing Powder Coat On Fork Lowers

I used some industrial paint remover to get the powder coat off the fork lowers, and then cleaned them up with some 2000 grit wet and dry paper.

Virago 750 Fork Seals

The fork seals were really nasty, so I renewed them as well.

Front End Assembled

I cleaned up the brake rotors and also sprayed up the brake calipers.

Drag Bars

I left the original handlebar risers on, but fitted some wide straight "drag" bars.

I also went for Biltwell diamond grips to match the bobber seat.


Electricals

Some people love it, some people hate it. I actually don't mind it.

As long as you label everything, and you have a decent multimeter what could go wrong...? (just about everything!) Luckily it's not the 90's anymore and the internet will solve any issues you might come across.

Ignition Relocation

I extended the wiring for the ignition and found a spot to relocate it.

Wiring LED Indicators On A Virago 750

Getting LED indicators to work on older bikes can be a bit of a challenge, and the Virago 750 is no different.

After loads of internet time I found a solution. This is what worked for me.

I spliced in an LED flasher unit as shown in the photos.

This made the indicators flash, but a little too fast. So I wired in some resistors to the rear indicators and everything worked perfectly.

You might find that wiring in a variable speed LED flasher unit would work better than wiring in extra resistors. (I'd already wired in mine and couldn't be bothered dismantle it all again.)

Aftermarket Speedo Wiring On A Virago 750

This is where taking the time to label all your wires pays off.

Wiring up the speedo is pretty straightforward; the only problem you will encounter is making the indicators flash independently because the speedo only has one indicator bulb.

The solution is to wire two diodes to the indicator wire on the speedo and then onto each of the live wires on the front indicators.

It sounds confusing, but it's actually pretty easy. Hopefully the photos below will make things clearer.

This is the speedo on the bike. I've used this particular speedo on a couple of bike builds and they are a great little unit. The mechanical drive is the correct ratio for the bike and it reads in MPH.
 

Headlight Mount

When you remove the original instrumentation from the bike you're left with the problem of how to attatch the top of the headlight.

I decided to make a bracket from 3mm aluminium plate with various spacers and washers. I glued some black mesh from an old speaker over the hole in the top of the headlight housing where the cables used to go. I was pretty happy with the end result.

Relocating The Fuses

I decided the best place for the fuses was under the tank running along the bottom of the frame.

I just extended the wiring and replaced the original fuse set up with inline fuses.

Fabricating The Exhaust

After looking at hideously expensive aftermarket exhaust systems, I decided to fabricate the exhaust myself.

I bought 2 sections of flexible exhaust, two sections of chrome slip on and some clamps. After a few mock ups I got something I was happy with.

I made a bracket to support both exhausts and fixed it to the frame under the rear foot peg. I also slash cut the slip ons.

Lastly, I wrapped both exhausts in titanium wrap with stainless ties.

Seat Mount

The seat mount was actually pretty straightforward.

The main part is a section of square tube bolted through holes that are already in the frame.

To accommodate the studs on the seat I just added a couple of extra brackets measured to fit them. The front is just bolted through the original hole.

Virago Bobber Seat

The seat mount was actually pretty straight forward.

The main part is a section of square tube bolted through existing holes in the frame.

To accommodate the studs on the seat I added two brackets with holes measured to fit the studs.

The front of the seat is just bolted through the original hole.

The wiring under the seat was really visible so I made a cover from some really thin pattered aluminium A4 sheet. (You can easily bend the stuff with your hands) and sprayed it black.

This is the seat on the bike. The angle on the seat perfectly matches the angle of the frame. In my experience anything made by Biltwell is of excellent quality. The leather is good quality, the workmanship is excellent and for a slimline seat it's suprisingly comfortable.
 
I added some caps to the frame where it was cut, and also added a rear reflector. (It looked like it needed something in the space)

Finished Virago 750 Bobber

All told the project took around 10 months.

Really happy with the end result.
