Reliable CDI?

[Karl Snarl]

That would have been my second guess if the first was not correct...lol.

That pretty much sums that up for me as well.

If i want to be constantly screamed at by females...ive got three in my house...they're called cats...lol...much easier to put up with...lol...DAMIEN

Only one kitty here. But if you really wanna be screamed at, a woman aint nothin, get a pet pig. Scream loud as a jet engine. Lol. He's a good boy though.

get a pet pig.

Yep...Had one already...it was my ex-sister in law...lol...She was a pig in more ways than one...lol...When she came to my wedding with my now ex-wife, she came with a guy on each arm, none of whom were her actual husband at the time...lol...She's been married four times now not including various BFs...lol...And she was loud too...probably louder than your pig...lol...DAMIEN

Oh no, oh no no no. Don't dis a pig like that. Lol. They are very respectable creatures.

That sounds like a load of crap

Thanks @Street Ryderz , and thanks for the coil info. So, I'm guessing that upgrade CDIs are made with better components, and have higher output coils? I have experience designing circuit boards (Eagle CAD). Does anyone have a schematic of a CDI that would work for this application? I would need the component specifications.

Do a google search. Plenty of wire diagrams out there to pic from. I recommend using jaguar's. He took the base from a dort bike cdi and just added a couple channels to select from on the curve. Jags cdi is the best out there for us. Im just not willing to pay over 100 usd for a cdi on a bike engine that cost 150 bucks.if you google, the moped guys have his cdi mapped out. An on his page he tells you what he modified in the dirtbikes cdi to make it what it is. Really easy to build, specially since you have experiance soldering up boards.

Jag's cdi is NOT best suited for a true performance engine build, it's only good upto 9k rpm and craps out after that. The bike berry cdi's strike and lightning strike are just copies of Jag's without the curve settings and to be honest still have too much advance, the super charged cdi (pill bottle) from Jake Busey is much better suited because the base timing is lower and the single curve drops lower at 10k and above, I use the super charged cdi they are only 20 bucks then I get a buddy to replace the cap and do what he does so that when tested at 10k the timing fires at around 8 degrees btdc instead of 30+ for a stock unit and around 20 on the strike units, moped and scooter engines have much better ignition systems that use inductive pickup/trigger with built in curve better suited to higher rpm as they can turn 11-12k easily. The older Yamaha pw 80 cdi works well (pre 2003) as it's a wire loop system same as ours and has a suited curve. There are alot of schematics online to make your own cdi just have to do some research to see what would best suit your needs.

Never said for a performance engine. Best cdi for our stock to mild mod engines that is bolt up and go. Many way better designs out there, but you have to build yaself or fab it into your setup. Best cdi would be a hall sensor adjustable on the fly. But why spend 800 bucks on a cdi for a 150 usd engine.

I thought you were the guy that loves to spend thousands per year on your hobby...lol...DAMIEN

@Street Ryderz Check the image below. Is this the CDI you are talking about?

Yes that's the one, very good for high rpm not so good for those whom just want to put around as the base timing is lower and without mods to the engine may seem slower to accelerate.
