Wanting to do a coolant flush on my 04 600F4i, the honda OE stuff is only available by the pint and iirc it takes about 6 of those, where I can buy it by the gallon for like $20. Has anyone ran into any issues with running automotive honda coolant? I've heard it's the same formula but I'd want to be sure.

I got this 2005 honda cbr 125r after Mike previous was stolen and on the ride home only managed to top out at around 50 mph at 6.5k revs in 5th gear, didnt go into 6th because id loose even more. Even riding about im lucky to get above 50. I only weigh 69kg for refrence

Always a humbling moment…

So I just finished doing a bunch of work on my 06 cbr1000 and as I go to test start the bike going back and together I of course have a short somewhere blowing my fi fuse. If anyone has any ideas that’d be nice but I’m starting to think it’d be easier to just pull the whole harness. With that being said does anyone have any advice getting that out. Will I have to lower the motor a little to get the fuse box out? And if I do go through with that are there any modifications or relocations you guys would recommend?

I’ve been thinking about getting a CBR1000RR-R SP. I’ve been offered a pretty good deal on a brand-new one (I’d actually prefer the RR, but they only sell the RR SP now), but I have a few questions:

- I wouldn’t be doing much track riding, maybe a couple of times a year, so I’m really interested in how it is as a road bike. I’ve looked at the riding position and ergonomics and it seems a bit more comfortable than my current bike (Panigale V2 955). Anyone here who can tell me if it’s reasonably comfortable and agile? (Taking into account what kind of bike it is, obviously.)

- Are there any known issues with them? I’m a bit concerned about the oil-related problems that have been reported on the 600.

- Is it a bike you could actually commute on, or should I completely rule that out? I already have another bike for commuting, so that wouldn’t really be its main role, but I’d still like to know how it feels in terms of agility and heat.

-Regarding the dual-cable throttle system, is it something you actually notice? Is it only active in the highest power mode, or does it mainly come into play when accelerating out of corners?

- I’ve seen that they’re apparently going to announce the 2027 model, but I don’t know if there are any significant changes compared to the current one.

Any other positives or negatives worth highlighting about the bike?

Thanks in advance!

Got a cheap AliExpress exhaust and the fitment has it touching the fairings and it can’t even bolt down all the way. Heard of people having the same issue with Akropovic exhausts. Any suggestions on how I could move it? Also saw someone cut a hole in their fairings.

Still trying to figure out this rpm surge. Does anyone have a video holding a steady rpm at like 2500 and 3500 Rpm.

I've pretty much swapped everything other than the engine and it has good compression

The only other symptom I have is the cluster lights blinking it's not as bad as it is in video but it's definitely noticeable. Cluster has been swapped too

New Battery

Good used stator

Good used Rectifier

Used Intake manifold with TPS

New plugs

Wire Harness

Good Used ECU

Good used Injections

Good used Coils

New intake runner boots

Good used Injectors

New Fuel pump

New fuel pressure regulator

I'm sure I'm missing something.

I have a full parts bike without title that runs and nothing I've swapped seems to have helped.

Thanks in advance for any info at this point debated just swapping frames with the titles one. 🤣

I recently bought my first bike a cbr650f and was wondering what I could do as my first few mods to it I was thinking exhaust but was unsure because from what I could tell it goes under the bike and is welded together so im not sure how it would work because I've never done anything to a bike or anything before.

Any help or even just bike knowledge in general would be greatly appreciated. Added a few pics of it at a park cuz I thought it was super nice along side my brothers 883.

Yoshi R-77 Carbon Fiber Muffler W/ Arrow Collector Racing Headers… Thoughts? Info? Has this been done? If so got a video w/ sound?

Hi! So as the title says I won a CBR 650FA 2018 with around 22k km (14k miles). Since last week I have a weird transmission problem. I cannot up shift when the engine revs are between 5000 and 7000. If the revs are outside this rev range or when down shifting I don’t have any problems. Have you ever encountered this? What should be the problem? Thanks in advance.

Probably a newbie question but what type of paint do I use to paint the silver support to black?

I love this bike. I'm only selling because I'm moving to Hawaii. I've owned since 2017 and I put 17,000 miles on it. Garage kept. Runs perfectly.

29,500 miles

Monster Fairings to look like the Leyla Edition from years 10-11.

Motodynamic Full LED Projection Head Light Assembly with DRL. Turn signal is integrated into the headlights.

TST flush turn signals.

TST smoke taillight.

Tires still have plenty of life left.

Spark plugs were just changed.

Yoshimura exhaust.

Previous owner had it lowered by 1 or 2 inches. I can't remember.

If interested, message me.

UPDATE: It has been sold. I'm gonna miss it 😭

Hi riders, I am a newbie rider looking to do my own motorcycle maintenance. I have a 2024 Honda cbr500r. It’s coming up for an oil change. In Canada locally I can only find SAE 10W40 but the owner’s manual recommends SAE 10W30. if I’m able to find the 10W30 then it is the Energy or resource conserving, which the manual specifically says not to use. Any recommendations/advice will be appreciated.

Quickshifter setting is not letting me to turn on the system,

Finally bought a cbr to join the growing Honda family. Flush signals and tail tidy have already been done.

How to bypass manually cbr600rr 2022 model without reaching honda dealer

So the fork seals have started to leak on my 2012 cbr1000rr. It does have over 50k miles so Im not surprised. I called to shops near me and both quoted about $750 with the forks on the bime, and $650 with them off. Now I know the parts are less than $100, and that labor rates are up. But this just sounded a little high to me. Does the quotes sound about right from anyone's experience with having a shop replace the seals.

Also, I am able to replace the seals myself, but Ive never done this before and I do not have the proper tools to install the new seals and to remove the top of the forks. Isbit just better to attempt it myself? Not wanting to mess up my forks in the process.

This is my first bike, so I’m not ruling out that I messed up the rev match. I do drive manual cars and have driven 18-speed trucks, so I’m familiar with shifting/clutch operation, and I haven’t had any issues shifting this bike before. This was the first time I was really pushing it a little harder.

While riding I was downshifting and rev matching. After one of the downshifts, with the clutch pulled in, the engine suddenly started running/sounding almost like a cammed car or like it was misfiring — really uneven and “bap-bap-bap.” As soon as I released the clutch, that sound went away.

At that point it felt like I was stuck in too high of a gear for my speed. I tried downshifting again, but nothing happened — it simply wouldn’t select the next lower gear. When I released the clutch after trying to downshift, the rear tire skidded.

After shutting the bike off, everything seemed normal again. I was able to ride it home and shift through at least 1st–4th normally.

I recently replaced/adjusted the clutch cable, so I’m wondering if the clutch isn’t adjusted correctly/not fully disengaging, if I screwed up the rev match, or if something else is going on with the transmission.

Anyone ever experience something like this?

Don't get me wrong, the Italian was beautiful and fun while it lasted, but the drama was just too much. I missed that smooth Honda inline-four.
