    Help, please! Engine overheating 🥵

    I have an ongoing problem with my 22GT. I have taken it to two different dealerships and they have not been able to diagnose the issue. Relays are good, continuity is good and the fan motors are good. When I get into traffic I know to switch over to the temp reading because if it goes a half...

    ****** guards / engine heat guards

    Has anyone seen something like the Capt Itch guards for the Rocket 2? The heat in Texas is pretty brutal before the motor starts to cook you. I have ordered a slip-on exhaust, which should help with the cat heat. I also ordered carbon fiber exhaust manifold covers and read all the pages in the...

    R3T and Roadster engine differences...

    Good day group, just wondering if there are internal differences in the RIIITs and RIIIRs, such as cam or were all the performance differences done in the ECM. Reason why I ask is many sources say the R#T is 92hp and 120ft lbs of torque at the wheel. I just threw a tune at my 2014 RIIIT and it...

    SAI / SMOG removal

    Hey guys, I'm wanting to know a bit more about the Secondary Air Injections system and removing it after a Meerkat Exhaust Mod. From what I understand it mainly for better emission numbers and assists in deceleration. It also seems to be the culprit in the piping and backfires. I am wanting to...

    Momentary voltage drop? / check engine light

    My 2014 RT3 has been lighting up the check engine light randomly (but kind of regularly). It will be on for a bit, the ECU will reset it after a bit and then mysteriously it will come on again. Had the dealer check what the issue was and they said its a momentary voltage drop that trips the...

  8. Engine Axle Bolt in a bind during crash bar install

    So... We were installing a new set of German crash bars on a 2018 Rocket III Roadster. We leveled the bike up, put a scissor lift under the front of the engine for support. We tapped out the old rod with the new rod going right in behind it. When the old rod was just about out, it stopped...

    RPM for a stock engine?

    I am curious what the experts here think the top RPM that I could run without too much risk for the stock Rocket 3 engine? Current dyno runs on my bike look like it is limited at ~6700 RPM. Would 7K be too much, 7400? I am not sure how much margin they build into these engines.

    SAI Delete Kit for 2.5 engine

    I tried to sell this on eBay but they cancelled the auction because of 'ecological issues' - a bit harsh if you ask me ..... Anyway, I have this kit which I was intending to fit over the winter but I sold the bike so it is no longer needed. £40 including postage to anywhere in the UK. Go on -...

    Engine Question

    I have had two people tell me if my Rocket is a 2007 it should have a black engine? What do I tell them?

  12. Small Burn Marks on Side of Engine

    Hi, Could anybody tell me if these burn looking marks are normal or not.

  13. Height of Engine?

    I am trying to swap a R3 engine into a 1969 Triumph spitfire and the only person I could find online that posted pictures of this swap sadly passed away last year. These are his pictures and the only ones I could find online. It looks like the valve cover won't clear the hood, and I'd like to...

    The engine turns off when changing gear

    Hi everyone. Happy owner of a 2023 Rocket 3R with 900km on it today, I have a problem. The engine occasionally and suddenly switches off when changing gear, therefore with the throttle at 0 and the clutch pulled. Can anyone tell me something about it? The Triumph workshop told me that for the...

    Engine Case bolts.......?

    For you guys who have the opened and closed the crankcase, did you replace all the case bolts or did you reuse the bolts? I plan on using new bolts for internal parts, and to save $150, would like to reuse the external case bolts. The external case bolts only torque to 28nm so maybe safe to reuse?

    Unable to switch engine modes.

    For the past month, I have been unable to switch my '22's engine modes. Since new, I have been riding my R3 in 'Sport' mode almost exclusively, but it now seems stuck in 'Road' mode and nothing I do will get it back into 'Sport' mode, which I generally prefer. I did replace the bike's battery...

    215hp street build

    Sparky picked up the engine today for this build. Talk about Brotherhood! Sparky dont talk it he walks it! I wouldn’t be able to do any of this without his help. A great big brother. The Man in the tin shed is cooking up some cams for the 10.5:1 JE pistons. Gonna get it home, tear it apart with...

    Struggling to figure out the cause of misfires

    Hi everyone. My 2008 R3T is driving me nuts. She works perfectly on idle, but misfires start as soon as I open the throttle. Doesn't matter how wide the throttle is open, engine keeps stuttering, backfiring and all that. The setup is Ramair/TOR/Nels tune. I've thrown in new spark plugs, new...

    Engine is making oil.

    Well I bought a new to me 2013 roadster last month. I shook it out a bit and had no issues, so decided to take it for my vacation trip. Now I'm over 600 miles from home and it is making oil. My next stop is/was going to be Nashville TN. I'm assuming that it is an injector problem. Are these a...
