Can you please let me know whether you are running 6V or 12V? Also have you advanced the timing? Any other attendant modifications?

I like your tone

@joe- i'l make sure i stop the SMS lingo.


AND FOR THOSE HAVING A PROBLEM IN UNDERSTANDING THE LANGUAGE- No offense. But the description is not mine.Its a copy paste from orkut. I did not have enough time( or did not find it necessary) to correct the language before the pasting it here.

Anyone who doubts the capabilities of the product can come and check out my stock 5 speed, which does 120 kph on the gun. Only RDD CDI and RDD Filter kit on it.

And people here need to grow up and grow a few brain cells.

And atul about static being a curve joke. The reason your bike is still struggling at the 130 kph mark is because its on static timing.

hey joel

with all due respect to you here, i wish to express my opinion

I agree when someone says the RX cdi works for a stock bike..But Im confused how the same CDI works for a 4 speed barrel and a 5 speed barrel at the same time, knowing how different the power characteristics are for both, and when they both need different curves [or maps as they like to call them] doesn't make sense to me

And when someone tells me they are performance CDI's, its time for a good laugh. How do you expect a given curve X to work for a RX that has a custom designed head, a radical port setup and an expansion chamber thats kicks in equally aggressively, when that curve was primarily designed for a stock bike?

The usual answer given for this question is usually" Use curve 2" which is not a curve designed for a modified bike's power characteristics. Its another "one size fits all" curve that retards the timing earlier than curve 1 [max advance curve] That makes no sense.

I'll give you my own example..I got my hands on the RDD digi3 and the digi5 for the drag RX project I am still working on. I don't claim to be a world famous tuner and run down on other's work, but I do know how to setup a bike. And to back my claims, I sincerely believe in investing in diagnostic tools rather than the butt-dynometer and cheek-flapo-meter or "intution-bike-run smoothly vibration-gone" meter too. With +4 degrees advance on curve 1 or 2 on the cdi's, the bike refused to go above 118kph on the sigma [ i run a setup similiar to psycho98 here] With all kinda of advance dialed in with 91 octane fuel, the bike didn't pull beyond that.

Similar story with the digi5. Not only this the bike used to shut down in the powerband, which is scary at some 9000rpm in 4th gear. And yes with the best plug caps and the same wiring setup..I did the same speeds again..I gave away the CDI for a bottle of motul 800 2t coz its no use asking for a refund and give an explaination for something that is not my fault and still works like crap on my bike

Plonked the stock CDI and have been doing the runs you guys saw in my drag bike thread with seriously conservative porting and a pipe with 87 octane fuel [regular unleaded] and hitting speeds in excess of 130kph. My exhaust port is 30.5mm from the rooftop, so that gives people an idea what my port setup is

Thats all I have to say

Cheers

ah thanks for the tip torqu3e.. i'll get there soon..albeit on my own..thats the only difference..but no thanks stock works fine for me

btw, did ur RX cross the claimed 150kph?..or the same 132kph record holds? with a crazy port setup, the digital CDI, your weight and all the powerjet carb and the works? We're all really curious coz with all that jazz ur current 132kph isnt really a consolation..I hope you better it soon


cheers

Converted to a 12V system. Yes, the timing was advanced as recommended by RDD and the only other 'mods' are a HP filter, oval slide RX carb and a Pulsar Disc setup. The bike is a 22 year old RX100 converted to a 135 with a 4 speed barrel.

I haven't claimed 150 anywhere.

I will post what I do, when I do. My 16 hours a work day is not helping me with my bike plans.

Hey Atul, I'm not talking about a works engine man. ofcourse the 4-spd and 5-spd power characteristics are not the same.
Indeed for a works engine, u need a new map. I know there is nobody in the country who has one such fully-programmable unit and I'm working on my own way.
This is with respect to a stock bike only.
You want to go racing, get some fully programmable CDI which can work for every parameter u want. Everything else is a compromise da.

Thanks for the swift response Where did you buy the filter & the carb from, may I know?

Hey but torque, I do remember your gearing calculater methods and u indeed had plans to crack some great numbers if not 150kph exactly

Phew lots of bashing going on huh !!!

Guyz everybody have there own views regards to any product, why don't we share the same in a calm way please.

I believe this stuff will be useful if it can accept user defined timings at various points across the rpm range. Else not much useful. As it was said, one size does not fit all. If you are making something custom make it user customizable as well.

You got a few things wrong herein. I know nothing about 2 strokes. I never built one (as you did). Somewhere I also asked what is a reed cage - how did you miss that? Then, I own a Shogun and a RX. I owned few Shoguns earlier. Owning a thing does not necessarily means, you have to know the bottom of it. If I remember correctly, I met you when I went to Zen TVS Bangalore last January to acquire parts for my 'gun, and being such stupid as you indicated in your post I was grandly duped by them in Bangalore's shiny daylight. I did not know Zen TVS sells fake spares to stupid people. Thats another story anyways. Obviously I am not smart as you are when it comes to steeds.

I am not into tracks. I am not a tourer. I know how to ride my bikes and of course yes I feel free to ask about things that I do not know, online or offline. I come here to learn things and share and help people if I can. For I was not born as some with all the 2-stroke knowledge in my brain. Blame my parents for that. I know of a few in this forum and some other forums who have such "GOD" attitudes because they feel that way. But for me, I am a very ordinary 2-stroke lover who love to know more about 2-strokes if time permits my schedule.

That said, thing is what made you pissed off so much with my post - as I said, it looked like an advertisement - so does it. Thats my opinion. Period. The question whether I will realise (or do realise) what is a good CDI is or not, or a RDD cdi rocks or not, or whether its a post about CDI or a DD Underwear is out of my post's parameter.

The next time you insult a person in a forum, know this it does not add any karma to your image. So keep that GOD attitude in your pocket and move on.

exactly my point joel..as far as i remember, there's one single RXG/RX135 cdi availible with one max advance curve and a max retard curve..how will it be common for the 4 speed and 5 speed barrel. even if both are stock

I also agree that for a works bike, you need a custom curve to exploit the max potential of the engine..it'd rather make sense to run a static ignition there than a wrong curve that is not built for my bike, which is exactly what happened in my case

racing, hell yea why not..im already planning a trackday with guru and put a few laps down in the next few weeks..i have zero clue about riding and i really don't have any skills in that department..but what the heck i'll do it anyway..im sure you'll agree

and yes..ur last point is true indeed..for a performance RX, everything but a custom curve/fully programmable is a compromise, even if its digital or transistorized

cheers

so the 132kph holds for now..2kph more than my 130 with the best porting works, lighter weight, 18 inch wheels, a downdraft carburetor and the fabled CDI is working marginally better than my poor DIY porting, stock CDI and a fake china keihin pwk coupled with my 79kg fat arse and did i mention this was on 4th gear?..but its ok..im not gonna start with excuses here coz thats not how i work..130 is my best for now and heck im gonna keep working my way up. thanks for the sympathy but you can keep it for the 132

better that and we shall talk about me taking tips about where my bike is struggling..atleast im open about what my plans are and how things turn out for me, even if i fail miserably.

and yes i study 8 hours a day, work on people's bike for a living, do my mundane activities and can still cough up time and cash for making a bike with no fancy tuner god's hand on my head..it all boils down to commitment and priorities. Thats all

Atul
