Many people have problems with exhausts and body fasteners coming loose on their scooters and resort to locking fasteners and such however you do need to examine the bike for CVT and Clutch issues causing high and low frequency vibrations that are many times the root cause of the problem. The locking fasteners will many times just mask the bigger problem which will still be there until the worn part causing the vibration finally fails.

seeing as these engines seldom use any type of lock washer, it seems this would be a common problem.
most of my "loose screws" were due to poor body panel design.
there were only 3 instances where "important bolts, screws, and nuts" came loose or came up missing altogether.
one was a muffler bolt, i even lost the rubber shim on that one.
one was the engine to swingarm screw, bolt simply disappeared.
the 3rd was the rear wheel nut, it came loose, but i never lost it.
i had the socket to fit it but not the breakerbar, (i was away from home).
i used a pair of pliers to get it tight enough to get me home.
the chinese must have some kind of aversion to lock washers.

Most use crush washers or clutch nuts with the crush washers built in on the machined parts. They have to be installed with a torque wrench to set them properly and too tight or too loose will leave them prone to coming loose. The are considered one time fasteners, then you toss them and use a new one.

The way I look at things is it 100% failure proof are not like fasteners many thing you can't control. But in this case you can I live in country travel may miles on ruff roads not like many people who live in city and some times cell phone service is null. My wife and I go out in summer and rack up at lease 200 miles on each trike or more I just like nothing coming loose because of nuts or bolts more so on a long ride I'm out to enjoy not repair loose things LOL Only reason I posted about if some one had the problem this was a sure cure that's all. The company says they have a 100% non failure rate and that's good for me LOL

Yes locking fasteners are great however they do not eliminate the need to replace worn bearings and out of balance assemblies. |

I have 3 trikes all same issues it is the nature of the beast with the 300 cc vibration it has to some degree. Heck my friends Harley trike shakes more so and his shake cost 36,000 and many tell you use lock tight on all assembly why to you think it's needed LOL

Heck my friends Harley trike shakes more so and his shake cost 36,000 and many tell you use lock tight on all assembly why to you think it's needed LOL I can only relay what almost 50 years of experience has taught me. Yes scooters vibrate however when they start breaking or dropping exhaust fasteners its very often high frequency or low frequency vibration at the root of it. You still need to validate that there is nothing going awry in the cvt especially since most of these bikes have no support bearing supporting the clutch shaft at the clutch bell. If you have a vibration that is loosening the exhaust you are prudent especially if you feel buzzing under your feet through the floorboards to check out inside your cvt case. Many times lock tight is needed because folks are curing symptoms and not getting down to the root cause such as reusing a crush nut instead of purchasing a new one, banging on a drive face cockeyed or violating the tensile strength of a fastener with an impact wrench, not replacing scored drive faces, leaving on a compromised belt that vibrated so badly that the composite weights on the clutch arms shattered, failing to grease the roller bearings that ride on the clutch shaft, replacing an out of balance clutch without repairing the bearing damage usually done to the input bearing on the gear case are a few examples of root causes for fasteners vibrating loose. You really want to get that as smooth running as possible so the only real vibration is the piston cycling up and down along with possibly some chain noise if the bike is so equipped., |

I was only telling people of products available for these problems now to answer your question I call 3 dealers they tell me for a few years they have be working on the problem even add on more better type mounts for vibration they even sent special nuts. I didn't like the fix so that is when I found this real fix and it does the job with out any more problems. If you read the whole thing it stated I have 3 trike all have same problem 1 maybe 2 and 3 no I really can't go along with you on what you stated sorry.
