Electronic Ignition - Is It Worth It ?

[jon v8]

Sorry if this has been done before,just wondering if anyone has direct experience of fitting one of the kits to a Ty250 - the type with inbuilt advance.Reason I ask is that whilst I really like the low down grunt of my Ty,it is a bit flat higher up the rev range.It is in good nick a generally runs very well,except I wonder if the extra ignition advance would give a bit more top end zap.Or would the 270cc big bore be better ?

jon v8,dont know if you saw my bit on the ty175 electronic ignition which is now fitted to mine and a mates bike,we should be doing a trial this sunday and I will post the results.Cant see why they should be that different to the ones fitted to the ty250.

Hey jon you out bid me on the ty cylinder on ebay. Re the ignition I would say shop around as they do fluctuate in price. I believe a mate of Woodys does a deal on them. Cheers

I haven't really had a chance to run my Majesty 320 properly with the latest electronic ignition kit as the bike (not the ignition) has a problem which isn't sorted yet. However, I have tried a replacement CDI unit on my Ossa from the same supplier as the Yam ignition and there is a noticeable increase in pull at about two thirds up the rev range. I'm not talking double the horsepower and all that bull, but there is a difference from the standard CDI and the bike will rev really hard on climbs. Bottom end is unaltered but when the revs start climbing I can feel the extra surge from about two thirds throttle.

If the Yam ignition is configured the same, then the affect of fitting it to the TY should be similar but as mentioned, I haven't been able to try mine properly on the Majesty so I can't say for a fact. I had one of the early electronic kits fitted to the Majesty (with the black Slovenian CDI box) and I couldn't really tell any difference over the points set up, but my main reason for fitting it was convenience and to do away with points/condensor maintenance and mishaps, a 320 isn't in need of any more power.

As regards a big bore kit, a 72mm piston is only going to increase the cc to 260cc with the 64mm stroke and I can't imagine 10cc extra is going to provide any sort of dramatic power increase, it's not much different from going to maximum oversize.

Woody who do I contact about buying a replacement ignition to fit a MAR?

Thanks

You can speak to/e-mail Colin here;

TY Offroad

He should be able to get you one from the makers. It isn't a complete replacement ignition (ie; stator and CDI/coil) it is a new CDI unit and HT coil which uses the existing stator. Fairly straightforward to fit, it just requires a new bracket making which bolts to the existing frame mount to attach the two components as they won't both fit straight onto the frame mounting. I've tried it on my '75 350 MAR and can tell that it revs harder.

A new Ossa stator from the same source may be a future availablity.

Thanks for all that,Bo - sorry bout that,has it stuffed you up on a rebuild ? I only bid on it as it completes my spare engine,(apart from a rebore/piston) If your stuck shout and I'll post it to you.Woody - thats exactly what I'm looking for in what you describe from your Ossa,be good to know how your 320 performs.Andy,good luck on Sunday - let us all know how it works.

Cheers Jon.

No jon I bid as it was cheap, but didn't bother bidding again I thought the postage was a bit greedy, I may be wrong. Probably the engine is the best part of my TY. It's the rest that needs money throwing at it. Cheers
