CTX1300 engine whine reduced

Hi fellow CTX riders. Some apparently enjoy the whine of their V4 engine; we don't. We bought our CTX1300 two weeks ago with only 3900 miles on it; currently also own a Street Glide, Dyna Wide Glide, R69S, & a 650 Burgman, and was casually looking for a lighter smaller bagger when the local motorcycle dealer showed my wife & I this mint condition CTX1300, a Harley trade-in, at a very attractive price ($6900). One short test ride and we were sold.. In the spring, we like it enough that we're planning on selling both Harleys & the Burgman scooter (gonna keep only the Honda & old /2 BMW). Anyway... In the quest to quiet the Honda's engine whine I tried several different oils to no avail, and this morning tried adding MT10 oil additive (a 'metal treatment'); initially demonstrated to me years ago by a friend who used it to quiet his Ford's power steering whine.

I'd previously changed the oil to Red Line synthetic, then Golden Spectro synthetic blend, and the whine remained with both. I tried adding 6 ounces of Lucas oil stabilizer; went for a 100 mile ride and again no change; and finally this morning added 8 ounces of MT10. Initially there was no difference but within 15 miles of riding, while cruising at 55 mph, the whine suddenly diminished to nothing - it was literally gone. There is still some whine at idle and some at high RPM; but cruising at 55--60; there is none; and the whine that remains at high speed & idle is much reduced. We rode two-up today a distance of 200 miles and there were no negative side effects, no clutch slip (something I feared), and a rhythmic grinding noise while cruising (transmission noise) is also reduced. Shifting is also smoother. I'll post again regarding this if anything develops good or bad. If anyone is interested, MT10 is produced by Muscle Products in Pennsylvania and is available online. I've read both good & bad about this product on the internet but have used it over the last fifteen years in our cars & other bikes with nothing but good results. It has made balky automatic transmissions shift properly and has quieted power steering pumps. BTW, I'm a retired surgeon and have no affiliation or business incentive with this product.

Now... if I can only find someone in NE Ohio competent to install cruise control...

Welcome to the forum @docD

That whine (what remains) is a characteristic of this engine caused by the front end square cut gears and other mechanics of the engine. No oil will make that go away since it is nothing to do with what oil touches. The noise is known by ST1300 owners as the Jetson space car sound or Singer sewing machine sound. This engine and transmission, and many other parts on the CTX1300, came directly from the ST1300 which was produced from 2002 to 2012. This engine has been proven to be rather bullet proof over that history. Most ST owners love that sound, if not at first then as they became accustomed to it, and actually miss it when they ride a different bike. The louder whine you may have heard initially is likely due to being new.

On oil... I don't recommend any particular oil other than to be absolutely certain the oil you use is NOT Energy or Resource Conserving. This should be indicated on the SAE circle on the bottle (most of them anyway) as a blank lower outer ring of that circle. Being a wet clutch any oil that IS Energy or Resource Conserving will cause slipping issues with the clutch and possibly failure of the clutch over time.

Cannot help on the CC. But there are members here who have installed MC Cruise or Rostra cruise controls.

Thanks Bob, I appreciate your opinion. It's good that some enjoy gear whine because this engine has it more than any other I've heard in 50+ years of motorcycling. Personally, we prefer a quiet engine with a subdued burbling exhaust note and find incessant loud gear whine annoying. If the risk of a shortened clutch life (possibly) is the price we must pay to reduce it, we're okay with that and will take that chance. The reduced whine we experienced is dramatic; not minor; and whatever or however it should not have occurred is of little value. If you have any suggestions besides learning to like it (which will never happen), I'd love to hear them and would surely give them a try. BTW, now retired we ride quite a bit (20,000+ miles annually); if something goes awry I will promptly report it. Best, & enjoy the ride.

Welcome @docD . Regardless of the whine coming from this motor I thought it was telling that after riding the CTX you are considering selling 3 of your bikes!

Concerning cruise control, I have the MCCruise system on mine which I installed myself. To my knowledge that is the only real cruise system available for this bike. The company is out of Australia, they ship directly to the States and the system is expensive. Right around $8 or 900 if I recall. It took me probably 10+ hours to install. I was in no hurry and it was the first time I had taken the bike apart to that depth. The instructions included were the best I've ever seen for just about any product. The company used a CTX for their install instructions and took pictures with good verbiage along the way. Top notch. Of course the most important part is that the cruise works perfectly every time I've ever used it (which is quite often). Lots of info here on the forum for this and other ideas. Just do a search.

The other system I was interested in is Rostra. Unfortunately that won't work with heated grips, which I have.

Thanks for the heads-up on the McCruise; it looks like the way we're going to go. I installed a throttle lock several days ago and, although helpful, it's definitely not cruise control. For fear of preaching to the choir, what we find impressive about the CTX1300 (a bike we weren't even aware existed before), is the superb fairing wind control (w/the tall screen), the adequate power, the low center of gravity, and the feet-forward riding position using the highway pegs. In the past we've owned several Gold Wings and RT BMWs with engines where my feet now must go (c/o arthritic knees). BTW, regarding the MT10 & engine whine. I understand that the noise will always be present to some degree due to the gear design in an area not lubricated with engine oil; but obviously much of the whine is also from the rotating assembly that is lubricated. I'm surprised that Honda stopped short of installing a quality suspension both front & rear, cruise control, and a real stereo; especially at the bikes original MSRP. However, even with its shortcomings, it's still an enjoyable bike easily rideable by my wife & I on our frequent 2-300 mile cruises.

Whining about the whine is annoying, there doc. Ride your harley farm implements if you don't like the high tech CTX whine.

Welcome to the forum, @docD . Hopefully, you will grow to love the CTX even MORE after a few more months/miles - as most of us here have.
@planar tube - welcome to the forum. And, that was quite the introductory post ...

Shame on you planar tube; knocking other brands is of no value to the motorcycling brotherhood. We love motorcycling and have been fortunate to own virtually every major motorcycle out there in the past twenty years; from a 1929 Indian-Ace 4 cylinder, '48 Indian Chief, '65 Panhead Electra Glide, countless BMWs, Bultacos, Velocettes, Hondas, Kawasakis, Yamahas, etc up to our most recent Indian Vintage & Chieftain, five Harleys, three Gold Wings, 2 Moto Guzzis, a CanAm Spyder, and.... this CTX. Several of our vintage bikes are now in the Barber Museum and several European brands (Ariel Square 4, Royal Enfield Interceptor, Ducati 750SS Desmo) now reside in collections back in Italy. Some recent summers we've bought 5-6 only to quickly sell them when we didn't bond; but we like them all and denigrate none. Harleys have their charm but as my wife & I are getting older & weaker (age 66) I find their FLH touring bikes too heavy overall and too top heavy for our always two-up riding especially on gravel-strewn & substandard country roads. I was looking into buying a Motus when this CTX popped up. It's time to scale down, pare it down to only a couple bikes, and find a touring bagger that is lighter & with a low center of gravity.

CTX1300 engine whine reduced

docD,
I for one hope you bond with the CTX and it makes your ďkeeperĒ list. Itís obvious you know bikes and riding. Iím finding similar good things about the CTX and itís performance.
Iíd love to have cruise, heated grips, and additional fuel range, but none of those are show stoppers for me. Iíll add what a can. Already added the center stand, highway pegs, panier guards, Michelinís, and a rear rack. Still tweaking it. I put on a bead rider, and threw an Alaskan sheep skin on over that. (the added height helps the knees, just turned 65)
Iíve had lots of bikes myself, and love riding. Just finished a 4,800 mile trip on my CTX, which solidified my decision that itís a keeper. Fortunately the gear whine doesnít bother me. With the ear plugs in, and some tunes in my helmet I donít hear it. Iím always solo as my lovely wife prefers four wheels to two.
Welcome to the forum. It could be one of the smallest groups Iíve been part of. I donít know how many CTXs were manufactured, but itís small compared to the Goldwing community. More folks here posting about what they are doing with and to their CTXs will benefit us all..

Wow MoPops, 4800 miles is a long ride. Congrats. We had a patient show us pics taken on a trip to Alaska on their Yamaha Venture. Whoa... stunning. A 9000 mile round trip and they couldn't wait to do it again. We had a GL1500 at the time (mid '90s) and I feared it too heavy & cumbersome for the substandard roads up there (paved w/rocks the size of bowling balls) so I bought my first Electra Glide Ultra. Unfortunately, an injury canceled our plans and life got in the way later on. Now we have the time and I'm trying to get our CTX up to the trip. So far: Corbin seat w/backrest, highway pegs, tall windscreen, passenger backrest, grab-on foam grips, adjustable levers, and SOR throttle lock. I still need to install real cruise control, brilliantly bright road lights, and improved suspension (both forks & shocks). BTW, I sent a GL1800 to Traxxion Dynamics several years ago for $2500 worth of work and it came back riding so stiff (the opposite of what I asked for) that I am leery of having them rebuild my CTX forks. Maybe we'll try preloading the springs and using 5wt fork oil. Thanks for the nice welcome.
