Very, very new to this community.

I want to customize my old bike with a self start along with user authentication via Bluetooth using a smart phone. I can make the electronics part (Means Software and small work on hardware) only. I have no idea where to place the device on the motorcycle.

Any suggestions to help me solve this problem?

  • Welcome to the site @mvaustin What year is your CD100? – DucatiKiller May 13 '16 at 4:48
  • 2003~2005 model its not the old model(CD 100 ss) – M V AUSTIN May 13 '16 at 5:41

    I think you need to edit your question and put in some requirements. Requirements make the world a happy place. How much space to you need? Is there a temp range for the service limits of what I assume will be a circuit board? Do you have any specs on vibration? Vibration is a real killer. Think about your requirements for a moment and below your question, hit the edit button and bullet point them. You will be helping someone be successful if you add in all the data you can. Welcome to the site. Cheers! +1 for your question, I really like it. – DucatiKiller May 13 '16 at 5:55
  • Thanks Ducatikiller,as you said there is temperature factor for the circuit board,there are lot of other parameter such size,power,sensor,...i will get back to this site after a small discuss with my team – M V AUSTIN May 13 '16 at 6:21
  • Think of environmental specs (moisture, temp), vibration (engine and road) and space requirements. Good luck! – DucatiKiller May 13 '16 at 6:55

I'll start with the bad news - if it's the CD100 model without electric start then it's a no-go unless you replace the engine (I'm inferring this from your statement "customize my old bike with a self start"). You won't be able to retro fit a starter to it as the cases and internals will not be configured for one. However, if the engine does have electric start, read on. :)

At it's simplest, your circuit should be made to activate a low current relay that can itself be tapped into the feed to the starter relay (in parallel with the starter button wiring) so it can energise it and turn the starter motor.

You then need to consider safety aspects - has the bike got any safety interlocks in the starter wiring? Look for clutch switches (clutch must be pulled in to start the bike) and side stand switches (side stand must be up to put it in gear). These are there to prevent starting the bike in dangerous circumstances (in gear or about to ride off with the side stand down). Don't try and work around these, work with them and fit them if they are not already on the bike. You don't want to try and impress your friends by remote starting the bike when it is accidentally in gear and it goes tumbling off the stand onto the floor!

Good luck with the project!
