2003 Big Dog Mastiff

Ok, here is the story. At the end of last summer I saw an ad in the paper for a 2003 Mastiff. It stated that the bike only had 2900 miles on it and was in like new condition. When I got to the privately owned bike shop, the owner who was selling the bike for a customer, introduced himself and stated that he used to work at a Big Dog dealership as a mechanic and now has his own shop and almost exclusively works on Big Dogs.

He showed me the bike and it was in gorgeous condition. After a 40 minute conversation as to the workings of the bike and him stressing that it was a very high performance bike and very temperamental, I took the bike on about a 15-20 minute test ride. The bike performed very well and seemed to be in perfect working order with the exception that the speedometer did not work. When I got back to the shop, I inquired about the speedo and he told me that the original owner, a very short, overweight pizzeria owner had bought the bike mostly to show off to his friends and that it was just way too much bike for him and that he did not want to go through the expense to try and locate and have a new speedo installed. But the shop owner assured me that he rarely rode the bike and that the mileage he quoted me was fairly accurate (within a couple hundred miles).

So I purchased the bike for $10,000. I rode the bike to and from work most days for about a month (11 miles each way) and started having problems with the oil pressure light coming on and the bike sputtering and then just stop running. I gave it a few minutes to cool down and then it would reluctantly start back up. I called the shop owner and explained to him what was happening and his answer was that I was probably treating the bike too harshly and giving it too much throttle. Again, that it was a very high performance bike and that it needed to be babied and that I probably fouled the spark plugs. I took the bike up to him, having it go through the same problem twice on the 45 minute ride to his shop. He took out the spark plugs and said that they were fouled and replaced them and said it should solve the problem as long as I handled the bike properly.

After about 3 days of the same back and forth to work ride, the problem started again. In addition, it was becoming more and more difficult to initially start the bike in the morning. I brought the bike back to him and he again said that the spark plugs were fouled and that I was mishandling the bike. At this point it was getting closer to winter. So I garaged the bike, had it on a battery tender and started it up and let in run for a while each week or two until it one day just would not start at all. I called him up and he asked if I could wait until the weather was better and he would trailer the bike up to his shop and see what was wrong with it now but he was fairly certain that it was a battery problem. I was thinking the starter was bad but I did not want him to know "my" opinion. I wanted to know what he thought was wrong this time.

He called me this morning to inform me that the starter was bad and that it needed a new starter. He was going to try to find the best fitting starter he could to fit the bike with the strongest starter motor so that I would not have this problem again. But he would call me next week to let me know what he has found and how much it will cost me to replace the starter.


Now that the story is done, sorry for it being so long. I really think he is blowing smoke up my ass. First off, since the first day I went up to test ride the bike, he was pushing the whole "high performance, delicate piece of machinery" bullshit. Probably because I pulled up on a 2002 Suzuki GSXr-750. Which I have put 49,000 miles on without needing anything more that regular oil changes, tune-ups and tires. He also has no clue that I've got a Harley Street Glide that I've put over 35,000 miles on with the same maintenance and have never had to replace a major component.

So am I to understand that this "precision machine" that was babied more than any of my other bikes had a starter go bad and had several other problems because I mistreated the machine? Are Big Dogs THAT fragile that you can't treat it the same way you would start or ride a Harley? Obviously I would not ride it the way some of the younger kids ride their crotch rockets, ie: stunts and damn near red lining the tach. I don't even do that on my GSXr.

Any thoughts, comments or ideas would be greatly appreciated.

Peace,
Mark

Only one red flag before buying the bike. That was the speedo not working and not being able to get the actual mileage. But I'm not sure if there is a way to take the speedo out and hook it up via direct wire to a battery to see if it will register the actual milage.

I'd be lookin' for a new mechanic if I were you. I'm NOT a mechanic, but here's the way I see it: Big Dogs aren't necessarily temperamental highly strung bikes, as sold off the showroom floor. They have a fairly bulletproof S&S engine and a high quality Baker transmission at their heart. BD proprietary parts, however, are another matter. Most of us have had electrical problems, and I have heard of starters going out occasionally. But, once again, BD's are motorcycles, and motorcycles break, that's just the way it is. We can minimize this issue by being proactive and doing our routine maintenance on time. I imagine you've had a few things go bad with your other two rides, too. But for a supposed qualified BDM mechanic to be telling you that your bike is "special" and high strung and that you should expect problems, and your riding style is to blame, simply sounds to me like he was aware that the bike had some issues and he was covering his ass just to make a sale. Also sounds like he doesn't know his shit. I wouldn't let the guy even LOOK at my bike, let alone put a wrench to it. He's just gonna fuck it up. I'd trailer it out of there if I were you, he can't be the only game in town.

Thank you. I am going to have it trailered out of there as soon as he calls me with his price.

I did look in this forum section for authorized dealers and the closest one is in Bergan County, 2 hours north. Ugh.

As for my other bikes, I get my maintenance done very regularly and have never needed a big pricetag part. Plugs, fluids, filters , seals, a chain or 2 and tires. I try to keep my rides in the best shape they can be.

Can't see in your profile where you live, and I have no idea where Bergan county is, but if you would like to let us know your location, I'm sure you'll get a few replies from our membership concerning good mechanics, hopefully less than 2 hours away. We have a lot of good members on this site, always willing to help when possible.

Welcome to the forum. Our old format would tell us where you are located. Hopefully some day we will get that feature back. You need to get your bike out of that shop asap. He more than likely screwed the other guys eyes out and has you lined up for next. if you keep fouling plugs you may have carb issues. It sounds like it is running rich. If you have a 107 inch engine and an S&S carb they are pretty much bullet proof. Let us know how you make out. Good luck.

being an '03 it may or may not have compression releases. if it doesn't, that makes it harder on the battery running it down faster. with an 11 mile ride each way, you may not be getting enough charge to keep it running at peak. as far as the starter, pull it out and send it to wildsteedworx.com (KaptainAmerika) to be rebuilt. no need to get a new one.

These bikes are not to be babied! My 2003 chopper romps! You have a 107 motor and it is roughly 105-109Hp. This is the finest motor S&S ever put out! These bikes are not cookie cutter bikes and usually have a mind set of there own as well as a different personality! Good news! Many of your parts are HD change out! In Stroudburg PA there is a HD dealer give them a call but get the hell away from this guy who sold you the bike and do it fast!! Also ask the HD dealer to run a Dyno on the bike. If it is running to rich or lean this can foul plugs. They car rejet the carb. Also. On top of your motor are your rocker boxes. Get a mirror and look down the center hole. If you see a condom looking thing, that's the cap for your compression release for that cylinder. If you see what looks like a nut head. That's the plug where you install them. The 2003 S&S 107 super sidewinder motor's were tapped for compression releases but they were an option. If you do not have them call S&S the electric compression release and wiring kit is about $360.00. As for starters that idiot should have said you needed a Spyke heavy duty 1.4 starter. There roughly in the $350.00 neighborhood. Also ask the HD dealer to chech out your EHC.

Thanks a lot brother. I can use all the info possible.

If he works exclusively on big dogs I'm not sure why he couldn't give you a quote over the phone.

Nobody works exclusively on a certain brand of bikes or cars for that matter and can't tell you exactly what it would cost to replace a 1.4kw starter

Sounds like this guy works "exclusively" on bullshit

I just test rode this bike, at Rommel Hd in Symrna De. Still has no speedometer or odometer, 10 minutes in the test ride , bike start to surge and buck, like I'm having a carb issue so I pulled off to side of the road and the bike shuts down, four try's on starting and finally *I'm riding again .And then it started to surge again pulled off the side of the road shut it down, and waited 5 minutes restarts bike runs fine, for a few minutes than here we go again. problem seemed to be in the ignition so I lugged the bike back to the dealership. The bike idle would change up and down about 400 rpm randomly kind of acted like a car with a bad coil.
I'm still thinking about buying the bike .but not sure about it. any Ideas

Check THIS out too. :oldthumbsup:

BTW, if this "Mechanic" was working for BDM he might be able to read the IM or the EHC and find out the exact hours/Miles this bike has actually done.

:hi:Just a thought, maybe the tank liner has peeled some off and is plugging the fuel petcock. After shutting down the liner relaxes from the pick-up and fills the float bowl, then when it restarts the liner is sucked back up plugging the pick-up again. :oldconfused: ( had a bean in the gas tank on a tractor that did that and about drove us crazy. Run, die, run, die) :willynilly:
