2007 FLHTCU Transmission Noisy 5th gear

Purchased new; now has 14,000 miles. Fifth gear (only) exceptionally noisy; sounds a lot like valves clattering. Other gears (1 - 4, 6) sound normal. Dealership mechanics say not to worry, but none of the "loaner" bikes they've provided during service calls are as noisy as mine is in 5th gear.

    Fifth gear in my 08 with 18k miles does have a louder bearing noise than the other gears, but prior to buying the bike I had heard and researched this. From what I could find out it has not shown itself to be a problem (yet?). I read of one fix out there and it is to change the type of bearings used in the tranny.

Wow, valves and other related engine noises don't care what gear you are in, they still make the noise. However your motor may be "lugging" in 5th gear which can cause a symptom of an engine related issue.
You may have an issue with the actual gearbox its self.
There is a primary drive chain that may be worn which will cause excessive noise in top gear because it is putting the greatest load on the engine. This is what connects the engine to the transmission. I think there is a tensioner for your model that will allow you to adjust the free play in the primary drive chain. If not I strongly recommend replacement because this will cause major damage if it breaks.

Why can't I engage fifth gear in 96 kawasaki vulcan 800

IS it noisy all the time or just when trying to get 5th gear? Hopefully just when trying to engage fifth gear. It is likely a bent shift fork. If noisy all the time a keeper on one of the shafts may have failed allowing gears to go where they aren't supposed to or a bearing has let go. Either way you will need to open up the tranny and investigate.

Throttle position sensor noisy

Are you sure it's not the idle air valve as they can sound louder after changing to a high flow filter...take the filter off and shine a light in the intake when turning the ignition on and off. The idle valve is just inside the intake in a hole at the top...see if it moves in time with the noise that you hear

2003 Electra Glide Classic. Very whiney in 4th gear. After several miles it was also in 5th gear. Now whining in almost all gears after 1000 miles. Seems to be getting worse. Lube on check stick seems...

Drain the oil and refill with 18 ounces of fresh oil mixed with 6 ounces of Lucas gear lube and see if that helps. If a transmission is whining, not a lot you can do except rebuild it. Are you sure it's the transmission and not the final drive belt. If the final drive belt is loose, it will rise up and rub on the bottom of the inner primary when you let off on the gas and make a whining noise.

Noisy transmission...07 ultra glide

If you look at my profile, I don't work on the later model bikes. Because of this, I cannot tell you how to fix your problem but I have heard a lot of talk about the 6-speed transmission being noisy. I've heard that the dealerships are replacing the final drive gear set with Baker gear sets. This is something that you may have to talk to the local dealer about. You could try adding about five or six ounces of Lucas gear lubricant with the transmission lube and see if that helps. Your transmission should take 20-24 ounces of oil. So, six ounces of Lucas with 18 ounces of Harley transmission and primary lube.

Good Luck

Hello, I recently purchased a 1973 Suzuki TS 185. The bike turns over and starts right up very easily. When the bike idles I can rev it and it seems to work very well in first and second gear. However,...

Check for air leaks. You probably need new crank seals and a new intake manifold. Check your reed valves if you have them and do not hold the throttle wide open if it is bogging you will score the cylinder by running it lean.

How often should you change your oil on a new 2007 yamaha warrior bike?

2000 to 4000 miles city driving, 3000 to 6000 highway or touring. The bike will tell you when it needs a change. It will run rough and be a little more noisy than usual (Vibration).

Yz 250 2008 possible 5th gear stripped, or shifting fork bent?

Do an oil change. If the gear were stripped there will be lots of metal particles in the oil. More than likely the fork is slightly bent such that the slider for fifth gear is just barely engaging. Put pressure on it by increased throttle and it pops out.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock.

Noisy 5th gear

but no there was definitely a loud whirring noise in 5th gear sort of like a very noisy bearing. The bike still ran in 5th but it was definately becomming increasingly noisy. When I changed down to 4th the noise went away even if I slowed to the rev range I had been cruising in 5th. Same story with the other gears, but the noise returned with a vengence in 5th. Needless to say I rode the rest of the way home in avoiding 5th. Any ideas? I suppose I'm looking at a gearbox strip? Could the noise be anything else? ,Had a similar issue with my 1000S, only 5th gear was noisy - a sound like a dry bearing -other gears were silent. Bike had done 70,000kms and serviced correctly. Had Barry from IME check it out. Turned out to be both 5th gears needed replacing - looked like the case hardening on the gear faces was eroding and pitting. New gears went in and the box properly shimmed and happy to say 6000 kms later all still silent in the gearbox department. Plus the added benefit of slicker gear changes.,,,
