It’s worth going to the website just for the great pictures like this.

Let me be up front with you, when International Motorcycle Shows first posted the trailer for this movie on Facebook I almost didn’t click on it. So often these “documentaries” about motorcycling are so one dimensional that they seem to be written for a narrow group of riders and/or racers. While I have yet to see the movie itself I have watched the trailer about 10 times already! There are interviews with kids, moms, street riders, Harley aficionados, crotch rocket jockeys, & racers from a variety of two wheeled motorsports all talking about how much they love to ride motorcycles & trying to explain the feeling to the rest of the world. Those of us who already ride understand the passion that just overflows out with the words they speak. Hopefully some of the normal people that get dragged to this film by friends and family will feel it too, and if they don’t at least want to try it will at least get an understanding of what draws us to these machines that so many people mistakenly see as deathtraps.

I ride a motorcycle & I love it. When I was a skinny little nerdy kid it was my favorite escape. No matter how bad my days at school were, when I slid that two stroke Kawasaki around a curve in the woods behind the cow pasture & then jumped one of the hills at the side of the canal ditch I was the ultimate 6th grade badass and all was right with the world! Today most of my riding is commuting back & forth to work on my ancient Honda, but it is still my escape and when everything is just right, I still roll on the throttle exiting that last turn before a long straight and pin it to the stop, while the ghost of Hunter S. Thompson whispers in my ear, “screw it on you big pussy” as the speedometer hurtles toward that magic number that all the Ton Up Boys lived & died for. It has been approximately 37 years since I got my first motorcycle and even though age and injuries have made me more cautious it still thrills me. Just like the first time! Every time. Even when just putting around at slow cruising speeds like the old fart that I am becoming. Bottom line is, I’ll quit riding when I die.

Even if you don’t visit the website at least click on this line and go watch the trailer!   Then come back here & tell me & the rest of the world why YOU ride in the comments section. I am going to close this out by quoting from the synopsis on the movie website.

“Your senses will heighten as the world rushes in, your heart will beat to the pulse of the engine, your mind will race and set you free. Once you let a motorcycle into your life, it will change you forever.”

Sums it up for me,

Peace Y’all

Dirt Bike Carburetor 101 Part 1 (how to clean a single cylinder motorcycle or atv carb)

Posted on by Motopsycho

Hello everyone and welcome to this multi-part lesson on the basics of carburetor  cleaning for single cylinder motorcycles. The cadaver we will be resuscitating in this lab is an 02 Honda XR100.

“barn fresh” xr100

Believe it or not this bike would still run with the choke on even with the dead gas and clogged jets, gotta love a Honda! This will be a general step by step guide to repairing carbs, so I will not be giving you the actual specifications as they vary so much from year to year on some bikes. As I’ve said before you need to obtain the specific information for your exact bike from a reputable source like say a service manual. For this first post let me show you how to remove the carburetor from this bike.

First let me say that it is possible to pull the carb from an XR100 without removing the bodywork, but A; you need to clean or replace the air filter and B; if it’s been sitting long enough to need the carburetor cleaned you need dispose of any fuel in the tank and clean it out before re-starting the bike after you finish the carb.

Now take off the side covers. This picture shows the location of the air filter cover on the XR100

Next look under the rear fender and remove the 2 nuts holding the seat on. Then pull it up and rearward to remove it.

I like to put the nuts and any spacers back on the studs like this so they will not get lost. In fact whenever possible I do this for all nuts and bolts as it keeps them from disappearing.

Now go the the fuel switch, valve or petcock, whichever terminology you use for it and turn off the flow of gas to the carburetor and disconnect the fuel line. Be prepared to cut it off with a knife and replace it if necessary.

Remove the rubber strap that holds down on the rear of the fuel tank and the two bolts at the front of the tank.

It is not required that you remove the shrouds like I did for this photo, I simply removed them so that I could show you the location of the bolts at the front of the gas tank.

After setting the gas tank aside in a safe location it is time to disconnect the throttle cable. On some models it attaches to an arm on the side of the carb but on simpler ones like this it is attached directly to the carb slide. Unscrew the cap as indicated by the screwdriver and pull the slide out.

This next shot is a little fuzzy but it indicates how the throttle cable is retained in the slide, and the following picture shows the slot in the side of the slide that allows you to remove it from the cable.

Now all you have to do is to compress the spring and push the end of the cable out of its hole, past the end of the slide, pull it out through the slot and then through the big hole at the top.

Here’s the removed and disassembled slide, jet needle, and return spring laid out for you to see.

Loosen the clamp holding the rubber hose from the air box to the carb and then remove the bolts attaching it to the engine and pull it out.

Yes I’m using the obstruction wrenches again. Two tools that I feel are must haves for any serious cycle mechanic are obstruction wrenches of decent quality and some extra long screwdrivers of the finest quality money can buy (i.e. Snap On etc.) Inexpensive wrenches are often okay but cheap screwdrivers will drive you bleeping crazy, by stripping out the soft metal heads on Japanese motorcycle screws.

Here’s a shot of the carburetor on the workbench. I like to use the red toolbox tray shown to help me organize the parts as I disassemble the carb, and to keep the parts from disappearing into the wormhole that exists behind my workbench. No part that falls back there is ever seen again, so I try to keep them from rolling of of the back edge. No dear reader I am not going to move the bench to look for them either. In my shop I coexist peacefully with all matter of snakes and spiders both harmless and venomous, and that is their territory and I stay out of it.

Don’t’ forget to protect the engine by plugging the intake hole while the carburetor is off.

I’ll show you the rest later, don’t forget to bookmark this page or to sign up for the email notification of updates on the right side of this page. Click here for part two!
