I have read a few posts regarding using a tci unit from a 2tk model when wanting to de restrict a 3en1 model. I found a 2tk unit on ebay recently but the fittings look different. They both have two multiplug fittings but the 3en1 seems to have more spade connectors than the 2tk ones? 8+6 vs 6+4!
Will it fit or do i have to alter any of the connections for it work.

I think Kayla tried it and didn't get it to work

Hi, my 3en1 has a 2tk ignition, I used to think all the 3en1's had them as a parts sharing thing from the factory. If I could get access to it I'd take some pics but cant at the mo sorry.
Cheers

IIRC : Neither Kayla or I could get the 2TK unit to operate the 3EN2.

All accounts seemed to prove the 2TK box was a plug and play for the 3EN1 harness.

Are you 100% sure it is a 2TK box ?

It should have 2TK on the sticker ... that's the biggest clue

I tried a 1WG Genesis box on my 3EN2 after I couldn't get the Ignitech one to work on the 3EN2 either. The bike would spin over but not fire with both the Genesis and Ignitech boxes. I ended up using an M-Max with the standard 3EN2 ignition on my race bike.

I suppose, given time, you could get the Genesis or 2TK box to work on a 3EN1/2 but I ran out of patience with it. It should work, given that the early 1WG engines are interchangeable, but it doesn't One thing it might be is the flywheel and/or ignition pick-ups need to be used with the specific ignition.

So many others one here have used the 2TK as a work around for the 3EN1.
Morespeed being the most recent and most informed.

Even if the OP was sold a unit as a 2TK part it is no guarantee that it is an actual 2tk unit....... without confirmation ,all replies are speculative.


For all we know he could have been supplied with a Genesis unit.......

Wait for Cleggy to put a pic. up of the unit or confirm the box label numbers.( he shouldn't be long.... he's only in Gateshead .)

This is the photo used in the advert on ebay, have not received it in person yet!

Looks like the same photo that's been used on this site in previous posts?

Got a feeling now this is'nt going to end well....

Certainly a pic of a 2TK unit anyhow.

Maybe the extra terminals are the restriction circuits that are not included on the 2TK .
I have not read any posts that stated a terminal swap was required.

The easy test is to fit the box when it is delivered. ( or Morespeed digs his bike out of storage )

Sometimes people try to sell things for a while but just have one picture.
Fit this up and see if it works.
