  1. Engine light was on

    2014 Rocket Roadster - Going down highway, bike's running good, engine light comes on, stays on. Headed home, only a few miles away. Bike still ran good at highway speed, but when I got off the highway, it started cutting out at slow speed like it wasn't getting enough fuel. A few hundred...

  5. When splitting engine cases for access to gearbox if there is a gasket between the jointing surfaces or is it only a sealant that is used?

    When splitting engine cases for access to gearbox can somebody tell me if there is a gasket between the jointing surfaces or is it only a sealant that is used? Thanks.
  6. Top Front Engine bolt size?

    Anyone know what the diameter of the long, top, front, engine bolt is? The one that holds the top of the crash bars. I need to purchase one a good bit longer, but the same diameter, so as to fabricate my sidecar mount. Thanks......Tim
  7. Mad scientist, building a R3-powered sports car

    Ooh I love that Rocket III engine! I make DIY sports cars and parts for other homebuilders (google <Locost cars> or go to <kineticvehicles.com> to see what I'm up to) and I fell in love with the Rocket III powerplant, so I bought a bike that had been rear-ended and after riding it a bit, am...
  8. Ooh man do I love that Rocket III engine!,

    I build oddball sports cars (you can see what I'm up to at KineticVehicles.com). I have one now that gets 100 mpg, it's powered by a three cylinder turbocharged Kubota diesel and the R3 mill would fit right in there. So I bought a 2004 model that had been rear ended, I've ridden it around for a...
  9. 2020 Rocket engine guard heat.

    The right side of the engine gets pretty warm during summer riding season, so to cure 90% of the heat I did the following. Removed the stainless steel heat shields from all 3 headers and lined the insides with exhaust header wrap using silicone gasket sealer as an adhesive. I cut the heat shield...

  14. Engine Running Rough

    This is a repost of an issue that I had inaccurately described and with more information. Was riding Sunday and bike was performing flawlessly. Came out of a stop after lunch and after 10 or 15 miles, could tell the engine was running rough- it was like someone threw a switch. No engine or...
  15. Thread lubrication on engine bolts

    Does anyone lubricate engine and case bolts with an anti seize grease when refitting them after removal and if so what would you use? Copper slip or alumslip (by Molyslip) anti seize compound? Is there a problem with galvanic corrosion when using copper slip on steel bolts threaded in alloy...
  16. Chirps from the engine while under load

    I've tried using Google, the search here, but nothing comes up. While in gear if I give it a moderate amount of throttle a chirping that increases in volume and frequency with the speed starts up. Sounds like a belt, yet the bike is beltless. Clutch? I don't seem to lose power, but I could be...

    Can anybody recommend a good touch up paint for a black R3 engine. I only seem to find paint that is high temperature and not petrol proof or petrol proof paint that isn't heat proof. I just want to repaint a patch on the timing chain cover where the paint has bubbled up due to corrosion...

    Can anybody tell me if I can get access to the oil pressure relief valve by only removing the bottom sump plate with the engine in the frame. It's a 2014 2.3 Rocket. Thanks for any advice.

    Just wondering if anyone has indeed done this? I have a rocket with a silver engine - Should be black and the silver paint is peeling in places - Yes silver engines are painted silver. I am not concerned if your preference is silver or black - I just want to know if anyone has had success and...
  20. Engine Light On, No power

    I was doing general maintenance when I replaced the shroud over the air cleaner. The screw caught a wire sitting just to the front of the opening and I saw a spark. Immediately pulled wire open (four wires in bundle) finding damage to the red wire. Fixed the wire, checked others and bike...
