TDR125 4GW

@Darty Here was my 4FU

As said I don't know natively if it supports domed, but certainly if you removed that ring and reworked the head

Mine might have been modified, the crown seems very different. No signs of a heavy skim. it's a closer match to a P' stamped head but with a squish height less than .5, A domed piston would crash into it at that point.

A base gasket would help, but then you begin to change port timings, not good. I gave up on a 4FU, Nicasil is expensive if you lunch the bore up.

[Calum]

Sorry my bad.

I have had a few 4FU's and they have all been this way.

Which is why I said it...

Another purchase sees the trail tech vapor and indicator dash added to PROJECT TDR.
I purchased the kit on eBay from Moore speed racing for £150 all in which I thought was a good deal.

Any of you guys run the vapor on a tdr/Dt before?

[Mightyman]

I always thought replacing my TDR clocks with something like this would look a bit out of place as the stock one moulds nicely into the plastics. Bet theres a big hole there now!

[tdr125greg]

@Mightyman I have thought about the same problem but how about 3d printing a new speedo surround then fibre glassing bondo, filler paint to finish ?

[Mightyman]

@tdr125greg That is a very nice idea actually! Would be even better if you could save the fussing with fibre glass and just get a snug fit with something 3D printed.

@finnerz89 looks tidy mate, how responsive is the Rev meter and do you have the radiator temp sensor or the sensor that goes on the spark plug?

[finnerz89]

Temp sensor that fits inside the radiator fin. I might get one for the plug and wire them through a switch

[Calum]

@tdr125greg vapor on my dt and I love it. Makes me feel like I got a spaceship at night with the shift lights flashing in my goggles. Haven't ridden the bike for years but back when I was a kid

[tdr125greg]

@Calum I'm really looking forward to seeing those shift lights in action

[Mightyman]

@tdr125greg The one I fitted to my MT-03 was SUPER inaccurate with the rev counter... I fitted it to the spark plug wire as the instructions mentioned but at 60mph+ speed the revometer would be all over the place, claiming I needed to shift all the time

[finnerz89]

No problems with rev counter on mine, it's wired directly to the coil

[Calum]

@finnerz89 Never had any problems with the counter myself.

On my new build it csn be wired directly to the cdi

[finnerz89]

@Calum is that with the zeeltronic?

[Calum]

@finnerz89 Yeah I believe it's the green/yellow wire that will pulse when the ignition fires. So no need to wrap the HT lead you can just wire it directly to the CDI.

I would double check the wiring diagram first mind you.

[tdr125greg]

@Calum I've been in talks with borut at zeeltronic, and I have decided I will definitely order the cdi and the programmer within the next 2 months. I've seen many varied experiences using the Rev counter but I'm assuming that's down to a bad install as I've also seen the Rev counter work great..
