Only a ton from Rex.

I thought they would've been more expensive than that.

When you look at the prices for an OEM CDi or TCi they're very good value.

happy after xmas . i did look into this and didnt know the 111 pound item is the same as mine.. i saw the handy post where some chap has dug the resin !stuff out and revealed a very inexpenxive to produce thing in my opinion..the force and others seemed a spensive y item,three hundred plus .which i know is difficult for most of us non pensioners or lowly gardeners to genorate.sorry to whinge.i know its a good investment for the future and as i want to keep mine as me orse forever i will have to wait.thank you for putting me on to the hundred quidish one .will try though it doesnt mount the same as my old cdi unit....like for like with these parts i think...effin paperweight without the correct working parts tho.have a good new year all.. :D

Yes, the chap did take one apart and decided it would be uneconomic to put it back together again

The part itself is key to the engine actually running and I haven't heard of any alternatives cheap or otherwise. Were it just the electrical components I suspect it wouldn't cost a lot but protecting them from the elements seems to be expensive

A sure sign its your CDI that is past its sell by date is if it kicks back when you are trying to start it.. The fault still allows the spark plug to spark but at the wrong time trying to run the engine backwards hence the kick start launching you over the bars or breaking your ankle. If there is zero spark it is usually plug, coil or low/high speed coil windings in the stator assy. High resistance of the Trigger coil (over 145ohms) allows the plug to spark outside the engine thinking all is well but the engine wont run or even fire..

We build or repair over 50 engines a year and this is what we have found over the last 30 odd years of working on Rotax powered bikes..

Hope this helps
