Where to find Buell parts?

Trying to help out my brother who lost his air filter. On the backing plate was something with tow wires coming out of it, I assume it's like a MAF. Maybe not....

The bike is an S2 Thunderbolt, I don't know the year. I've been clicking around and calling shops (DO NOT call a Harley shop). No luck.

Any thoughts on a.) where I might find parts, or b.) what the heck was on the end of those two wires and do you need it?

Thanks, Dan

Erik Buell Racing?

I'd probably ask this on ADVRider.com and see what the inmates there come up with.

http://www.buellparts.net ?

For all the Googling around, Buell.com never popped up. Why didn't I think of that? They don't have the part in their catalog, I've emailed them.

Thanks for the help guys.

I doubt it is a MAF. It might be IAT, though.

I'm not sure what the sensor in the airbox would be. Maybe an air intake temp sensor? If it is an IAT you might be able to get away with the generic GM sensor every home brew system uses. Buell was famous for using other manufacturers parts to make his stuff work. The fuel pump in an S3? It was a Ford part most often used to run the injection on Mustangs and such. Rear turn signals? Used by some Italian motorcycle manufacturers.

If you go to www.badweatherbikers.com you'll find a metric ton of info on those bikes. That's where all the tube frame Buell riders go for info, parts, etc.

For parts I'd check with American Sport Bike and/or BadWeatherBikers.com for used stuff.

Best place that I know of, and nice to deal with...

ebay is where I get parts for my bike from. See if you can find what you need.

I already did, NFG.

The good Doctor was right, Air Temp Sensor. I looked through the products at Buell.com and ASB with no results. I emailed both and only American Sport Bike responded, the part is $12.

I'm not familiar with the purpose of these, is there a negative impact if you run the bike without one for a while?

Try http://www.sportwheel.com/ in Minnesota, it's a huge motorcycle salvage yard.

Yeah, you need a IAT. Without it the ECU will either be way pig rich or way lean, and probably pig rich. $12 is cheap for a HD part. That "Hundred Dollar" joke isn't really a joke.

$12 IAT Sensor.

Oops, $20 minimum order.

OK, I can always us an oil filter, $7. = $19.

Rats. Chrome oil filter! $11. = $23.

Good to go!

Check out: $23 + $13 Shipping?

Keep looking.

all over the road

When you find a "better solution", I'm sure that you'll share.

PS--I work at a H-D dealership, and we have several Buell riders among the employees. When we can no longer get stuff from "Mother Motor", ASB is the go-to.

I have a theory that these IAT's and CHT's (cylinder head temp) can be replaced with a dollar part from digikey. You would need the specs on the original and figure a way to mount them. When I megasquirted Dr.Linda's Sportster, I bought a few thermistors from digikey with all the other stuff and used them for IAT and CHT. The IAT one I stuck in the air stream and siliconed in place. The CHT one I epoxied to a large ring terminal and bolted that down at the motor mount. They work great, but I can set the parameters for the temp curve. Without that ability, you need to find a thermistor with the same curve, which I'm sure exists, but you just need to work it out.

The IAT on the Buell (according to a Buell Board) is the same as on a '95 - '03 F-150. Motorcraft part DY-735.

$21 at the local NAPA minus employee discount.

Rockin' !!

That is not surprising. They used Ford parts in several other EFI places. The Buell throttle position sensor is a Ford part. You can see the oval inside the connector. I used a Buell throtle body on the Sportster megasquirt conversion and had to find the connector at the junk yard. Ford has them NLA. Found one on an 80's EFI V6 Mustang, if I recall.

Wow squirting a sporty sounds like a neat project. I think some people have adapted the efi system from the bigger buells to work on the blast. I honestly couldn't imagine any electronic part lasting on my bike as it shakes like a paint shaker. I'm still trying to figure what the cam position sensor and throttle position sensor do on my bike. Must have something to do with timing since the bike uses a traditional throttle cable to carb.

Parts for buells aren't expensive but if you go to harley almost everything is special order. The only really expensive stuff is brake pads for the buell. I had a 50$ gift certificate and the front brake pads were like 55$, same pads are like 25$ online. I just found that the headlight on my bike is from a car and can be replaced for 10$ at any parts store.

Yeah, megasquirting a 883 was like trying to put 5 lbs of E36 M3 into a 3 lb bag. I made the ECU from scratch based on a MS derivative work. A couple of guys took the MS schematics and threw away everything that wasn't needed to run a Buell, then made a circuit board. Apparently the stock Buell EFI system was pretty bad. MS was a big improvement for them. I was waiting for microsquirt to come out, but after waiting "any minute now" for a couple years, I gave up and went this route. This is the ECU: (collector cigarettes shown for size reference only and not to be construed as a smoking endorsement)

Finished:

Fuel pump is on the left downtube.

My Mom's 1200 sporty is the same color, turquoise, but she has a two tone fuel tank.

HD smokes, that was when a biker was a biker. My pops saw that HD introduced beef jerky and said something to the effect that they couldn't have introduced the jerky earlier because all the old bikers had bad teeth, they'd literally pull their teeth out trying to eat the jerky. Nowadays the "modern" biker is a lawyer with good dental care so it was time to introduce the jerky.

I doubt it's the exact same color. Dr.Linda mixed the color on MS Paint to match a rock, printed it out and I had it mixed at the paint store by a guy that did all his mixing by eye/hand (no computer to read the color). Then I painted it the base color, put the decals on and Dr.Linda drew the turquoise veins on and "Linda's Little Piggy" on the tank and I clear coated it.

I don't think they have the smokes anymore. Unfortunately, I don't either, as the mice got that pack. I hope the suckers got cancer from them on the way to the mouse trap. Yeah, after the Yuppies and RUB's (Rich Urban Bikers) moved into the scene, things sure changed a lot. I have been riding HD's since I was 17, LONG before I went to medical school. I'm a biker that became a doctor, not the other way around.

Maybe in San Francisco; but the Harley dealers within 50 miles of me don't want to deal with Buells. Actually some won't even talk to Harley owners unless you have an Evo motor or newer.

Business must be good.
