ahamayfrank Posted February 27, 2011 Report Share Posted February 27, 2011 I have a US model 1977 TY250D that I am quite pleased with overall. I have an intermittent ignition issue that I believe would be cured with replacement of the points and condenser, However I am looking for a good excuse to upgrade to an electronic ignition. I have already spent a bundle on it, so why not? I have read through a good bit of information after searching this site but I would like to stimulate some new discussion if folks here care to share experiences. I have seen three systems that are similar in price that appear to be available for my TY. Do other posters have experience with these or other systems. Electrexworld, tytrials, yamaha-majesty? Inquiring minds want to know. Thanks, Frank Quote Link to comment Share on other sites More sharing options...
feetupfun Posted February 27, 2011 Report Share Posted February 27, 2011 the tytrials unit works well and was easy to fit. The only difference I noticed was that there seems to be less variation between the strength of individual power pulses at extreme low RPM. I have not tried the others.

jon v8 Posted February 27, 2011 Report Share Posted February 27, 2011 I was going to go this route with my TY250,but it runs so well on points I couldnt see the point..... After 2 1/2 perfect laps on my Ariel today,I have to say I would have killed for a spark as good as my Yam has on points when the Lucas racing mag started playing up. I think the Yamaha ignition is absolutely fine,maybe the built in advance of the electronic systems might give a bit more top end if you need it,but reliability is probably top priority - which the original setup has.

searay175 Posted February 27, 2011 Report Share Posted February 27, 2011 I feel confident that I cured my intermitant ignition issues just yesterday with new points and condensor, cost for quality points ,condensor and flywheel puller was $40 usd. For my TY I would rather spend the $500 on a seat tank unit or new trials shocks. Quote Link to comment Share on other sites More sharing options...
