    Rocket 3 Roadster Possibly Overheating?

    Did you drain the expansion bottle or leave it hanging upside down before removing the rad cap?

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

    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

    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.

    Rocket 3 Roadster Possibly Overheating?

    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.

    Rocket 3 Roadster Possibly Overheating?

    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.

    Rocket 3 Roadster Possibly Overheating?

    OK. The air temp will change a lot faster than the coolant so need to make sure that the ambient air temp is fairly steady for a several hours first. Nighttime temps can change rapidly. Best left until mid late afternoon or such.

    Rocket 3 Roadster Possibly Overheating?

    Is this the same dealer that had it recently? Not sure if they're bleeding it right. Just to verify the temp gauge is reading somewhat accurately. Could you leave the bike acclimatise for several hours then check what the ambient/intake air temp is and the coolant one too. They should be close

    So there was trapped air in it? Run OK/normal temp now?

    R3 classic running like a twin. Backfiring and stumbling

    Good man you found the leak so. Classic vacuum leak strikes again. What are your throttle balance numbers now?

    R3 classic running like a twin. Backfiring and stumbling

    Unless you busted a head gasket, piston ring or dropped a valve then the cylinder will still pull a vacuum whether it is firing or not. Highest probability here there is a vacuum leak on the tube or the blank cap, also check the boot that connects throttle to cylinder head, seen them cracked...

    R3 classic running like a twin. Backfiring and stumbling

    Looks like you got a vacuum leak on #2, and that's why it running so bad. 880hPa is normally seen when at like 50% throttle, so when the ECU sees this is dumps in a lot of fuel, to try maintain correct AFR. Trouble is, the actual amount of air going in is still a trickle as the butterfly is...

    Rocket 3 Roadster Possibly Overheating?

    If the cooling system worked ok before but then not so good, and was due to trapped air, the only way i can see it getting into the system (aside from someone opening the system and not bleeding it properly after) is if the expansion bottle ran dry (say from a faulty rad cap allowing coolant to...
