Hey all, I've been stripping (whoo!) my bike like a crazy person recently, I've got the airbox gone and want to take on the battery next. I'll be buying a capacitor as suggested by everyone before (thanks), but I was wondering about the 2 thingers on either side of the battery, the rectifier and the CDI. Do I need em' without the battery? I'll bet I need the CDI, but what about the rectifier? I want to get rid of it, as I don't know what it does and it insults me when I look at it (i think)  . or have you just mounted them under the seat post-battery removal? thanks, Davey |

Hallo Davey,
the bike won`t run without the cdi and you need the rectifier /regulator to keep the voltage around 14V DC.
If you like to change your bulbs all the time you can do without ;D ;D
best regards
sjef

HI guys , I may as well ask this question whilst were on the subject . What is the advantage of changing from a battery to a cap , is it size , weight , run better or what ? I probably won't ever do it but I'd just like to know ! Davey if you didn;t have a rectifier you would also run the risk of baking your CDI as they don't like more than 14Vdc getting into them either so leave it there & never disconnect the +ve wire going into it ! Good luck Dave .

The SR CDI has its own power supply and doesn't draw power from the bike's electrical system.
The advanatges of a cap are less weight and no battery to deteriorate through use. If you buy a cap from an electrical supplier's they only cost a little, a 40 volt 10,000 uF electrolytic cap is what you need.
The down side is you have no lights unless the engine is running and you may have problems getting indicators to work propelry.

Hey, I got my Battery eliminator in there, but now my bike's a monster to start. I also threw a K&N filter on at the same time so it might just be super lean, but does anyone without a battery have starting issues? Bike seems labored and louder when it does start, then quickly dies, I'm thinking carby troubles.

If you put a K&N on, you will need to readjust the carb. |

Hey guys, thanks for all the info!
I've got my bike up and happy again, without a battery it still runs perfectly and idles with a strong horn and turnsignals at 1100 rpm! it's perfect the only difference is not having lights when it's not running.
I used a 35v 10000 uF capacitor with little metal tabbies. I soldiered lengths of wires to the tabbies, screwed them into the battery loops on the stock wires, and plugged those into the harness like a battery. I just bolted the CDI and rectifier under the seat on the old airbox/battery tabs until I find a prettier way to hide them, but in the meantime it looks great, feels great, and works great!
All I need's my low profile seat and a stolen gas tank off a CB350F and I'll have my dream bike, all for under $1500 US! incredible.....
