Thanks Darin,

The tank, seat unit and rear subframe come as a kit. www.caferacerkits.co.uk and are specifically made to fit the early Hinckley 900 and 1200 bikes, Tridents, Trophys and Daytonas.

CRK have just launched a new "airbox" for their Triumph Kits as well:

With these kinds of air boxes, what happens if you get caught in the rain?

Then you have water injection!

Nice build. I love the overall look.

I hadn't seen those before, nice, bit pricey though. I'm planning on having a 2nd attempt at the airbag, make it look a bit neater, probably not until next winter though.

Your cafe racer is the Mutt's Nutz. Very impressed.

I'm new to Sprint ownership and fascinated by the whole air-box saga. Any useful links to your solution? I'm normally bone idle but this might end up driving me into R & D

This was suggested by Greg96brg from this Forum as Yamaha use a separate ignition harness that connects to their main harness whereas the specified Triumph harnesses all coma as one so you have to buy the whole harness just for the connectors. I picked up the Yamaha harness on Ebay for 15 and the coils were 60 for 4. I also sourced some large grommets and cut a hole in the top of the cap so that they fitted around the coil and sealed the hole in the cam cover to prevent water ingress ...
Any more details for this? If it does away with the coils and saves a bit of space under the tank it might be useful for fitting the Thunderbird tank? I have looked at the R6 wiring loom and there are a few about on e-Bay, but it obviously needs a bit of an update to fit?

Thanks.

Swapping the std coils for the sticks would make lots more room under the tank of course as all that coil gubbins is replaced by just extending the 6 wires that go to the std coils to connect up with the new R6 connectors that are plugged directly into the sticks.

You would have to unravel the tape from the R6 loom and either make 3 separate lengths out of it or you can re-tape it into 1 having measured the lengths that you will need to reach each stick. There is a hard plastic corrugated pipe that runs under the tank protecting various wires. I sourced some more of that from Ebay and just ran the individual wires (re-wrapped with tape) inside those plastic conduits. I just used spade connectors to join the wires together, there have been no issues whatsoever and the bike runs very nicely indeed.
I also bought some 65mm closed rubber grommets from Ebay and cut a hole in the middle to allow the sticks to fit through them but will stop water ingress into the cylinder head recess.

I will try to put some pictures up on here if you like .... I think I have some.

It's a dead easy change only slight trouble getting the stick coil down into the middle cylinder hole past the frame but it's just awkward really, like getting the plug spanner down there. A wee bit of liquid soap eases the coil in just nicely.

Cheers Steve, glad you like, it was pretty easy to do and I enjoyed doing it plus having something a bit different.

As for the air box saga....... much has been written in this forum about it, some say don't touch it, leave well alone and others have changed it with varying degrees of success. I appreciate the argument that Triumph designers know much much more about air intake flow etc than I ever will but it is also true to say that much of what is engineered into bikes/cars etc has a lot to do with emissions which is something that doesn't particularly concern me. If the good old US of A has decreed that it doesn't give a tuppeny ****e about such things then my lil old 900cc Trident certainly won't make any difference to global warming.

I have heeded the advice of what I have read on here and elsewhere and gone down a half way house route. Obviously some of the air box system had to go due to the new look of the bike (secondary air boxes and snorkels) but I decided to retain the primary air box and filter (K&N) and modify that in the hope of bypassing the issues with pods that Mikuni carbs seem to have on these bikes. This was my first attempt and seems to be successful from a performance point of view as the bike runs very nicely albeit a tad rich but that just requires me to drop down a main jet size. It's all a bit trial and error. On reflexion, I think air box Mk 2 when I get round to it next winter will look a lot better than my first attempt but will also be on the same principle of a cut down primary box.
