Really Frustrated...(Life before the RDD Digi CDI III)

Post by akshai_ambrose »

Guyz this one is long overdue and I hope Ron can find it in his heart to forgive the delay..(What say Ron, no hard feelings..) :D

My Inheritance as I like to call it..My father’s 86’ RD 350 LT
Has been part of my family since I was 3yrs Old. :shock:

I arrived at Ron's doorstep sometime in Feb 07 with my RD with a dream to get her running as she did in her hey dayz.. 8)

Let me take you through the history of the bike, the year was 1999 I had just completed my 10th board exams when high on life I decided this was the day that m gonna break the land speed record on my rd. The bike at that point of time was running on Standard size stock bore and pistons and pionts (which were as I found out la8r mistimed). As a result the moment the speedo needle went passed 130km/hr I heard the the worst sound that I have ever heard in my life, as the bike came a standstill and the engine died out I knew what had happened!! Till date I m still trying to undo the damage caused that day!!! :x

The bike that I brought to Ron was running on an auto escorts points replacement kit and a re-sleeved standard LT spec bore with TKR pistons. As most of u would expect the bike performed like shit!! This ay had finally come after nearly 5yrs of convincing my Dad that he's gotta trust me with the bike by sending it down 2 Bangalore for 'The Doctor' to operate on it. :lol:

After Ron heard my sob story, he said that he would help me get the bike back to my Dad, and I quote "Running the way an RD should run"..With that said I paid the full amount for the Digi Cdi III and got in queue, along with me a very close friend of mine Sarfraz too followed suite for his 82' RD 350 HT running on points and a stcok .75 bore.

3 months la8r we finally heard, what was music to our ears..Rod had the kits ready and asked my Sarfraz to get his bike down for the install, the reason being that sarfraz wanted to go in for a before and after dyno test and hence his rebuild was a priority.(The results of which r posted on the forum) Nevertheless I waited patiently for my turn (Really frustrated..) :cry:

A month la8r I finally managed to get some of Ron's valuable time (in between his frequent trips to the coimbatore track) and I rolled my bike into his basement for the installation. The next day after Ron had patiently death with my lack of mechanical abilities we had managed to complete the CDI installation. The CDI in question was a second hand kit that was returned from Chandigarh, Ron had of course intimated me of the same and due to the shortage of Drums I decided to accept the kit. (U see beggars can’t be choosers..) :)

The moment Ron kicked the bike into life I could hear her scream like I ve never heard her scream before..The increase in the RPM and power band was quite obvious to me at that very moment. Two trial runs and I had a smile on my face that just wouldn’t die out! Thanks a Ton Ron!!!!! :D

All this happened in the month of June, why the delay in putting up this post u ask? I had a trip home (Jeypore-Orissa) and was caught up in the cyclonic weather which delayed my return to Bangalore where the RD sits in my basement. Still a lot of work to be done on the bike, the connections to the new switch gear, ignition, indicators etc r yet to be sorted out! :?

As things stand now, I was down with chicken pox for the past 2 and half weeks and m back home in Orissa, just counting the days till m back in bangaolore and get my RD up and running again. The bike is running on what I presume is an 18degree timing, on standard size re-sleeved LT spec, with standard LT jets. :(

I haven’t been able to run the bike ever since the day of the install..will update this post as soon as m back and the bike is complete and ready to be presented back to my Dad! :)

Ron as you said I am probably the luck one to get my hands on what you said might be the last RDD Dig CDI III! Will bring the bike over to ur place once all the nitty gritties are done. :cool:

[PS will still be expecting the analogue cdi box which I didn’t get!]

Never mind Bro.. Chicken Pox is infective only from 2 days before the appearance of the rash upto about 5 days after the appearance of the rash.. Not beyond that!!! Heh heh.. Just kidding dude.
But yeah, what I've said is a fact and not a joke.

The kit installed on his bike was this kit
http://www.rddreams.com/rddreams/html/i ... ic&t=14383
Wanted to prove a point.
It went on and ran fine with no issues. Same Coil plate and drum. Same CDI Box.

Pity your not getting to enjoy the bike more.
Hope you get to ride her soon.

And what happen to feedback from

Sarfaraz ?

The most common reason is the cheap resistor in the plug caps give out.
Chk the plug caps. If they are not showing 5K replace them.
The Honda APtiva plug caps thought a bit costlly seem to have the best quality resistors.

The symptom is bike will be runing fine and then sudenlly die on you.
You stop restart it and it fires right back up.
This indicates Plug cap being defective.

Next most common reason is a loose contact or short somewhere.
If you cant figure it out. Bring the bike and show it to me.

The CDI units are like a Bulb they either work or go totally dead. There is no inbetween.
Interment shuting off indicates an issue with EMI / Loose contacts.

Also if you dont use the bike for months on end and they try runing it without recharging your battrey it can cause problems.

The surrent plug caps are the Honda APtiva ones. I had brought NGK caps with 5 ohm resistance, but you suggested that i use the honda ones so i did. The battery on the bike was replaced and is a brand new Exide.
Currenly the bike is back home in Orissa.
As for the wiring i got that double checked too.
The symptoms are exactly as u described, whats funny though is that the time/distance when the bike goes dead varies. Sometimes it shuts down 5mins into the ride and on other occasions it runs fine for half an hr b4 goin dead..
What i will do is replace the plug caps and give it a shot.

This is a frequent problem with EMI / EFI
It either indicates a Plug cap issue or a Loose contact.
Double check your Earths. They need to be perfect. Check each of the bullet connectors. Sometime they are loose and you dont see it because the rubber cover.

can you bring the bike over or try another cdi im out of digitals right now.
What are the plug cap values, battrey values.
Hook u the cdi directlly to the battrey.
You have a loose contact smewhere.

I had a similar problem today.
On the new kit install.
Purchased 3 plug caps. All from Yamaha showroom. I took my multimeter and measured the plug caps. Before buying.
Installed the kit. Started the bike. It would start fine move a little and die.
Then sometimes it would backfire and re start runing if in gear. Changed the cdi, changed the wire finally when I went to re-check the plug caps found that the cheap friging resistor in the cap had blown.

Got a set of good plug caps and hey presto she runs fine no issues.

So even I get caught by this one from time to time.
This and the issue that the male sockets are sometimes too small for the femals sockets. SO with vibrations they act up. SImplly use a nose plier to squeze down on the female bullet to make the hole small then shove the male bullet in it should be a firm lock.
Typically this is on the HT coil bullets. As they are a non standard and small.

I had the earthing checked and changed the plug caps.The bike still switches off on the run at low speeds and at the signals.Ive got to switch off and restart the bike several times on the run.

i'd like to suggest you check your batt output voltage running and with the engine off.there was a post about this being a possible problem.i think tushar had the same issue.i don't know the operating voltages for the cdi,but if you've eliminated wiring and connections,the next best bet is the RR unit and the batt.
most pansies are content holing a piston.I went and holed a CDI.seee deee eye...does that turn you on?
