Diesel Motorcycle

Current Project Member: Maddison McGain
Past Project Members: Rocky DeLyon, Keoni Grundhauser, Zoe Chotzen-tsuruda

The diesel motorcycle was started by the class of 2010-2011. The students started with a used motorcycle frame and modified it to use a diesel engine. The fuel system is similar to the one installed in the Mercedes so that the fuel source can be anything from WVO (Wast Vegetable Oil) to petroleum based diesel. When complete the project will be used to demonstrate the improved efficiency of the diesel engine over a petrol engine. The project will also serve as a test bed for the different plant based fuels produced by the biofules team. The Diesel Motorcycle was completed during the 2012-2013 school years by Maddison McGain with the help of Mr. Gilson Kilhour.  

Up and ready to roam.....almost

I have been in charge of preparing the motorcycle to be efficient enough to test the biofuel.
 
The clutch was not properly maintaining grip when ascending uphill at a substantial speed so a major issue was finding a solution for that. A pedal was installed that put pressure on the drive belt. It was later perfected by adding a spring to keep it in the correct position.
 
The front headlight only worked on high beam which suggested that there was a wiring issue. Re-wiring was executed to correct all the light problems on the motorcycle. A wire schematic was drawn to track all wires on the morotcycle. Fuses also had to be replaced along with wires.
 
Later another wiring issue was uncovered. The starter switch was working without the key being in the ignition. The wires concerning the key and the starter switch had to be re-organized.
 
A speedometer/ odometer was added as well as the oil being changed.
 
The fuel filter was installed in the wrong direction so a new one was put in that went in the correct direction. 

Hopefully the motorcycle will be ready for testing before the end of the third quarter. There have been some issues with the battery, and getting the motorcycle started. I will be modifying the fuel system so the motorcycle will be started.  I will also be assisting with laying and preparing the concrete addition to the outside of the Engineering room.

Motorcycle Update! January 20, 2012

posted Jan 23, 2012, 3:23 AM by Seabury Engineering

Already, we have made a lot of progress on the motorcycle in the third quarter. One our greatest finds was by Michelle, who found the VIN number while cleaning and prepping the bike for a new paint job. This is significant in that we are now one step closer to making it street legal! With the help of Sid from the Harley Davidson shop in Kahalui, the brake for the bike is almost finished, because the brake is one of the most important components to a motor vehicle, we are not taking any chances and so it is taking some extra time. We had to order the headlight from Amazon, and it should be here in a few days. Keoni has been perfecting his welding skills, and made a storage box for money, phone, etc. on the bike. Michelle has taken on the task of painting the bike and all of its parts. I have been working on a protective box for the battery. All and all the bike is coming together nicely; it is exciting to see the progress we have made! 

2011-2012 Updates

This semester, the Diesel Motorcycle group accomplished almost all of the work to make the bike street legal. The group from last year gave us a bike that worked but did not pass the requirements to be able to ride on the street. Some of the more major things we accomplished include running a fuel system to be able to run different fuels, moving the seat back to make a more comfortable ride, fabricating extensions on the rear fender to hold it to the frame, running a rear brake from the handle bar because the peg did not have enough room, and loosening the drive belt so that it would idle. Some minor additions to the bike include, making a bracket to hold the rear brake handle on, and sanding/ epoxy-ing the tanks and fenders to be prepped for painting. Our project seems to be on track for finishing by the end of first semester. The main jobs that have to be finished are attaining the title for the bike, wiring all of the necessary components for a safety, and finish installing the complete rear brake and running the brake line. Overall, this semester has been very productive and is looking promising to be completed on time.


Death Trap

posted May 1, 2011, 11:03 PM by Seabury Engineering   [ updated May 5, 2011, 7:56 PM ]

These past two weeks have been quite productive. We went through many possible ways of making a fender for the rear tire and finally came to a unanimous decision on plastic. Michael and Gabe worked on welding brackets to the frame so that we can attach the fender to the bike. Zach and Ariel worked on making a cover out of aluminum for the transmission. Uncovered, the tranny belt was a death trap and would sever your foot off within seconds. But with the new cover, your left foot is no longer in any immediate danger. Michael also found an old kickstand and welded a pivoting bracket to the side of the bike. Gabe created a emergency stop pulley that will allow the driver to shut off the engine in an emergency. Also, we got the foot pegs mounted to the frame. Although we got quite a bit done, we were limited to what we could do because we are waiting on some key parts to come in. These parts will be coming in today and we will be able to get back into action on Monday










Finalizing Details

posted Apr 17, 2011, 5:13 PM by Seabury Engineering

The past two weeks the motorcycle group worked towards completing some of the major finishing touches on the bike. The sprocket finally came in so we were excited to attach it. After putting it on, we worked on adjusting our chain to make it fit properly. We also attached our finished exhaust pipe, and we were pleased to find that it greatly improved the sound of the engine. We are currently waiting for more parts to be acquired such as gas caps, brake pads and lights. We also need to finalize details with the DMV in order to make our bike street legal. Next week the different parts should be in our possession and we will be one step closer towards having our very own complete motorcycle!

Pillow Blocks

posted Apr 3, 2011, 11:50 PM by Seabury Engineering   [ updated Apr 5, 2011, 11:22 PM ]

These past two weeks the diesel bike crew has done alot. Here's the breakdown.
 
Week before spring break:
fuel lines attached
battery holder finished
spacers for transmission pillow blocks made and remade
wiring partially completed
seat installed
 
Spring Break:
Transmission pillow blocks installed with perfect alignment
fuel problem fixed
back tire spaced and stabilized
 
Week after springbreak:
keyswitch wiring completed
throttle adjusted and fixed
transmission mount lock-nutted
Mercedes moved out of shop
 
Also the Biofueled Mercedes has been ruined by a fuel leak into the crank case, now all the engine oil is actually vegetable oil. This project has been deemed unfixable in the time reaming this year, so we have abandoned all hope, and wish next years engineers luck. The mercedes part car was carefully disposed of in a unobtrusive, aesthetically pleasing way.








Pretty Comfy

posted Mar 8, 2011, 2:44 PM by Seabury Engineering   [ updated Mar 11, 2011, 12:06 PM ]

The past two weeks of motorcycle work have been going great. The team has been slowly piecing together the transmission which has been the main focus for the past week. This is because once the transmission is working we will be able to start the bike up and maybe even go for a test drive. The problem is the chain sprocket (the thing that connects the transmission to the rear wheel of the bike) does not fit, so we'll have to order another one from the mainland. The other projects we have been working on are sort of miscelaneous. We just started working on the fuel system, which we mounted on the bike and are now putting hose connectors on. We also mounted the throttle line with the help of Zach's dad Chuck. Ariel has been working on the starter button and figuring out how to mount it on the bike. I also mounted the seat on the bike, which might I add, is pretty comfy. Overall its been going really well for the motorcycle team and serious progress is definitley happening.






Focusing on the Motorcycle

posted Feb 14, 2011, 6:45 PM by Seabury Engineering   [ updated Mar 13, 2011, 1:33 AM by Martin Emde ]

Over the past week, our group has made a lot of progress. We have been focusing on the motorcycle while waiting for parts for the Mercedes. Most recently, we welded on the mounting plate for the gas tank, and then cleaned out the gas tank and proceeded to mount it as well. We also welded the battery box bracket onto the back of the bike, behind the engine. We began the process of designing our exhaust pipe system, and also machined a 1/4 inch steel plate to support the pillar blocks that we will soon be mounting. We welded the support for the rear brake caliper. Finally, we ordered the jack shaft sprocket and bought the master link for the chain. With concern to the Mercedes, we are still in the process of procuring the rear transmission support in order to move forward with repairing the car. Next week, the sprocket for the bike should arrive and we will move towards installing it if it is the correct part.








Earlier Than Expected

posted Jan 30, 2011, 7:08 PM by Seabury Engineering   [ updated Jan 30, 2011, 7:12 PM ]

  We have gotten allot accomplished over these past two weeks. First, we received the CVT Transmission for the motorcycle. This is great because it came in two weeks earlier than we expected. Also, we worked on mounting the engine into the motorcycle frame. We placed it on wood blocks and got all of the right measurements and then placed it into the bike as Gabe welded it into place. Once in, we were able to figure out what size belt we need for the transmission.

       Over these past two weeks, Ariel, the new addition to our group, did allot of work on reinstalling the transmission into the Mercedes Car. Michael, Gabe, and Ariel were able to get everything back in place except for a part that was misplaced by another group (they threw it out...). Overall, we were very successful in our efforts and it looks like we will be able to finish the motorcycle by the end of the year.
