    Rocket 3 Roadster Possibly Overheating?

    Be careful, the bleed screw is not the highest point in the closed system, just a bleed on a system pocket prone to trap air. You have to bleed at the bleed bolt, then keep topping up at the rad cap as I've described, BEFORE replacing rad cap. If one replaces the rad cap once bleeding is done at...

    Rocket 3 Roadster Possibly Overheating?

    So the root cause was indeed the faulty rad cap then. Simple fix. You're almost home now. Did you drain the expansion bottle or leave it hanging upside down before removing the rad cap the first time? Guessing not, and that's why all the coolant came out - the expansion bottle is above the rad...

    Clutch upgrade

    They are just bolts from local engineering supplies shop. I used stainless steel, and suitable penny washers.

    Clutch upgrade

    Good job finding and catching the prob before too late. Yeah you'll need a the new pullrod/lifter piece, pressure plate, pressure plate bearing and the wavy washer. Might as well get a new lifter arm while at it. Only other thing whil in there is 50mm long spring tower bolts to replace the...

    Can a Rocket III take down the establishment, and rule this island

    Well that's 22psi absolute so only 8psi boost. Ive not referenced boost for fuel or ignition, figured it's supercharged so a bit more linear than a turbo say. Just going with setting the tables myself to suit. Using a POD 300 to log pulls and video camera too on the gauges for good measure. The...

    Can a Rocket III take down the establishment, and rule this island

    Back when building it and doing calculations on the back of a pack of fags, I'd guesstimated a max 1 bar / 14psi boost. Seeing 8psi at 8000rpm I'd hope it climbs another 3-5 by 9000rpm. The boost climbs very quickly at the higher revs. Boost gauge on the handlebar for indication, it shows 12psi...

    Can a Rocket III take down the establishment, and rule this island

    As much as the charger will make... Haven't maxed out yet so don't know. Was hitting 22psi absolute at 80% throttle and 8000rpm so about 8psi boost so far. There's some T2 impeller upgrade available for these so might go there next but will see how it goes as is. Ive the ignition pulled back a...

    I think 5.5-6k is where torque peaks on the Carpenter engines, but this has been stroked and supercharged so that might change that a little. Time will tell I guess

    Tune ecu tune for 250hp carpenter

    Can a Rocket III take down the establishment, and rule this island

    Small update here, I've been back on the mapping and worked my way up to 80% throttle and near 8K rpm with very little pinging and AFRs are OKish. Did a test pull the other night, got some beautiful cone-shaped jet flames out the exhausts from 7-8000rpm. Also went from 50-90mph in 2.2 sec (which...

    Tune ecu tune for 250hp carpenter

    Sorry Kev I didn't see the thread. There are a couple of Carpenter 240hp 9000rpm maps in the Resources section, painstakingly converted from Tuneboy to TuneECU over the course of a few days.... if they're any good to you.

    Rocket 3 Roadster Possibly Overheating?

    Yeap that's it. And while we're at it. If ever in doubt about what coolant to top up with, just use deioniseded/distilled/demineralised water. It's cheaper and compatibility with all coolant (except expensive waterless coolant...). Of course any significant top up will need the right coolant...

    Rocket 3 Roadster Possibly Overheating?

    Distilled or deionised water is fine to top up with. Typically 50% of what goes into the coolant system is that anyway.

    I hope it's not the same stealership you brought the bike to & messed you around, that you're getting the rad cap from? A possible alternative if you wanted to give it a go - a shiny KTM one; https://www.r3owners.net/threads/radiator-cap-alternative.33277/post-529194

    Rocket 3 Roadster Possibly Overheating?

    Drain it by disconnecting the hose out the bottom of it, from the side of the filler neck, just under the rad cap. You could also just unbolt the expansion bottle and leave it hang upside down. You're just trying to prevent what's in the bottle running out when you remove the rad cap. If you...

    Rocket 3 Roadster Possibly Overheating?

    Looks like this might be the problem here so. The air temp and coolant temp are good. Seems like air got into system as above. You don't have to take the bleed bolt out altogether, just loosen it maybe 3/4 of the way out until coolant starts to run out. Then tighten up. Bike leaned over to the...

    You also haven't press the cap down and then twist. There's a step there to stop it opening unintentionally

    Rocket 3 Roadster Possibly Overheating?

    That's it there (yellow arrow). It's good for bleeding the cylinder head. Notice how the rad cap/filler spout is higher in the system. Need to manipulate air out that way too. But first drain the expansion bottle so it don't run out the filler spout.

    Should be OK yeah. This isn't a big thing, just want to check the sensor calibration isn't way off. I highly doubt it is.
