Thumbs up All tuned up

Hi everyone,

I've put a bit over 2000 miles on my Vulcan since buying it. In the last 1000 miles I've been tinkering with it, and as a result have found it to be riding much better since buying, not that it was riding all that bad in the first place.

When I bought the bike, it was popping and backfiring pretty bad. I thought that it would be really tough to eliminate it. I decided to marbled the reed valves, and adjusted my fuel mixture screws to 2.5 turns. There is almost no backfiring now. Wow... do those V&H's purr now.

After getting the backfiring settled, I had come to realize that one of my cylinders was knocking. I just couldn't quite be sure whether it was the ACCT's. I went ahead and followed the Grambo trick and had excellent results. The forward cylinder wouldn't move CCW at first, but after going CW, then giving a bit more force in CCW direction, it seemed to correct the problem. The rear cylinder spun CCW without much issue.

Finally, and what I would consider late in the game considering riding the bike for 2k miles, I checked the gap on the plugs. They were somewhere above 1mm, and I took them down to 0.8mm. What a difference! The bike was very eager to start up and feels more powerful.

In all, I'm very surprised how well the Vulcan rides. I was feeling a little disappointed in it, and thought it wasn't that great of a bike; I was wrong. Working out these few issues was well worth my time as it feels like a new bike to me. It's surprising how fixing a few issues can change the way the bike rides.

Needless to say, I'm a happy rider. Now I just need to address the ergonomics of the bike. I'm 6'2", and my knees are slightly higher than my hips, and is causing me discomfort... Any good suggestions on lowering the pegs anyone?

Well, congrats on getting her running good and quieted down. They are great bikes and lots of fun. About your long legs... You might gain some comfort by building some floorboards, but I kind of doubt that will make much difference for you. You're probably going to need to look at forward controls, which can be an expensive ($600-700 range) addition unless you were able to find them used or build them yourself. Boosting up the seat might also help but I don't have experience there. Maybe some others will give you some better, more useful advice! Good luck!

Yeah, unless you have the dough to do forward controls, you may as well consider the pegs fixed. If that's the case, you can always repad the seat to move your ass in relation to the pegs. Then loosen and rotate the handlebars or, if needed, get new handlebars. Given that most people want to change their seat anyway, this is a more economic fix than changing where your legs are via the pegs.

I had the same experience tinkering with the vulcan. It's a *great* bike, but needs some tuning help and some ergo help to realize it's full potential. Off the top of my head these few not very costly mods make the bike a scrappier all-day cruiser:

Pick-up coil Mod
Irridium Plugs
MF Battery
Cleaning the Ignition Switch
Seat repadding/beads
Small fairing
ACCTs to MCCTs (Kanuck method)

I've done other mods, but these alone can transform the bike.

For touring I added two samsonite hard aluminum suitcases via bolts onto the rail.

Other than that, it's just been performance tinkering.
I'm doing the semi-conductor regulator thing next, to support my new LED console/brakelights and 55w driving lights.

MF Battery, Iridium Plugs, RR relocated, Voltmeter, 170/80/15 Kenda Kruz rear tire, DIY Samsonite hard bags, DIY shaved seat with Beaded seat pad ('cause that's how I roll) and the dreaded STATOR CHANGE.

My suggestion here is instead of lowering the pegs or buying some $$$$$ forward controlls is to simply raise the seat.

Pull the seat off and just add a more to foam to the riders section. If you feel unsure about doing this yourself, contact :

and expalin that you need more height on the seat and I am sure for around 100 bucks Spencer will fix you up.

I made a set of brackets to fit a seat from a 2001 harley fatboy the seat is wider and more comfortable and slightly higher than stock which made the riding position much more comfortable on my knees.
