  1. ECU Identification

    Morning! Could anyone please help me ID this ECU? It was given to me as a R3 ECU, but I'm not convinced!!! :eek: I can't get any info off the net for the 'part' number (128 - or is that 8 actually a 9 - 2125), but the last run of numbers on the Keihin label (1292100) comes up as a...
  2. Project Build Using a Rocket Engine

    Not really been up to much... just removed the secondary butterflies on the throttle bodies and offered the engine up to the back of the chassis to get some ideas on the subframe design. As I've mentioned elsewhere, I'm thinking of turning the engine through 90 degrees anti-clockwise and...
  3. Inexpensive Starter Replacement

    Thanks. He has one at £200 ($305). Does that sound about right?
  4. Difference Between 'Classic' and 'Touring' Swingarms...

    Thanks fella's. (I should add that it's for my Trike project, so it will involve heavy fabrication anyway). (...and I should also add that I've changed my mind and decided to turn the engine anti-clockwise through 90 degrees and run a sprocket off the *supported* output stub).
  5. Difference Between 'Classic' and 'Touring' Swingarms...

    Evenin all, I'm trying to work out what swing arm to use for my reverse-trike project. I want to run an obscenely large rear wheel, so the engine will be getting offset and the swing arm I use will be getting chopped up and widened. Here's where it gets a bit confusing (for me... :D)...
  6. Inexpensive Starter Replacement

    Thanks. (... and apologies for missing the info in the thread).
  7. Inexpensive Starter Replacement

    Interesting stuff! My project engine arrived without a starter, so I'm looking for one that doesn't cost as much as one from Hinckley! ;) Are any of these higher-power starters a direct fit, or do they need some machining and parts robbed from the old starter?
  8. Project Build Using a Rocket Engine

    There's only one place to put an engine on a Formula 3 chassis and that's behind the driver.
  9. Project Build Using a Rocket Engine

    I wanted to keep the exhaust side to the 'rear' of the trike for packaging reasons, but I guess it's worth exploration.
  10. Project Build Using a Rocket Engine

    Just out of interest... do the Tourer and Classic models share the same final drive ratio?
  11. Project Build Using a Rocket Engine

    Thanks Warp. I've briefly looked into the Tuneboy unit and the price is not all that far away from an all-singing-all-dancing aftermarket ECU. The ECU's I have in mind will recognise all the Rockets sensors. Most importantly though, the dyno companies I use know the Omex, DTA, Motec...
  12. Project Build Using a Rocket Engine

    Something else I'm curious about... As I'll be using an aftermarket ECU, I can junk the rev limiter. Has anyone established what RPM the engine is good for (before if explodes into tiny little pieces :eek:).
  13. Project Build Using a Rocket Engine

    It's still very 'do-able', but it may make the back end of the trike a little too bulky for my liking.
  14. Project Build Using a Rocket Engine

    Was thinking last night about mounting the engine transversely and running a chain / sprocket as suggested and hit upon the following problem... Am I right in thinking that the Rocket engine's output turns clockwise (I've not turned the engine over, so I'm just assuming this due to the diff...
  15. Project Build Using a Rocket Engine

    Thanks Jesse.
  16. Project Build Using a Rocket Engine

    Ah! That makes sense to me now! I'll turn the engine through 90 when I'm next in the garage and see what kind of shape it gives me.
  17. Project Build Using a Rocket Engine

    Thanks guys. I appreciate the input. Warp... are you aware of any pics detailing the conversion you suggest? Also, is the R3T the Touring bike? If so, why would that be preferable to the non-touring model? Thanks again.
  18. Project Build Using a Rocket Engine

    Thanks for that. Is that a 245 width on a car tyre, or bike tyre?
  19. Project Build Using a Rocket Engine

    Hi Warp The trike I pictured is a Scorpion Motorsports machine. Their frames are made from tubular steel. They are based in the US and this is their website... Scorpion Motorsports | Three Wheel Motorcycle | 3 Wheeler | Miami, FL | Faster than Campagna T-Rex | Faster than Ariel Atom...
  20. Project Build Using a Rocket Engine

    ****.. mine is silver. Will I gain the extra MPH if I paint it myself!? ;) :D
