Hei fra amerika. I need more information. Does the rattle change with engine RPM? How many miles on the bike? It could be that the valves need to be adjusted and have excessive clearance between the cam and followers. Put your ear to the radiators while kneeling in front of the bike and rev the engine slowly to see if you can hear the rattling change with engine speed. If it doesn't change with speed, shut the bike off while coasting down a bumpy hill and listen. Could be the front brake pads or forks rattling. My 1199 rattles in the forks. Always has.

@@FancyAnimal the rattle dissapears after 4000rpm, it has less than 17000km thats is about 10500mi

Have you considered a Honda Super Chicken, AKA SuperHawk? Similar power and capacity motor to the RC51. Great street bike.

That is how my bike presented the problem... difficult starts on hot days. Try bypassing the EVap canister. You can always reinstall. Juat note that my video is for the 1199. V4 may have a different plumbing circuit. Just follow the tubing.

I made a cheap fix for the overheating issue.... create a fan override switch...$10. Throw the switch on at 175F degrees and your bike will stay under 200F in traffic. 230F - 240F will eventually ruin the motor from thermal cycling. kzbin.info/www/bejne/pKCvomaQmdOpidEsi=AF8vCjg-xcWhQo-x

Truthfully I kind of lost interest in KZbin for exactly the issues you brought-up. The KZbin monetization scheme and creator rules have turned content creators into obedient product placement lemmings. Everyone in every genre is reviewing products, selling products, or doing sponsorship boot licking. Consumerism is killing KZbin. Thanks for the feedback. Cheers!

@@FancyAnimalcouldn’t have said it better myself. I think it’s rather sad honestly, it’s almost as if the only motivation these individuals have is money. I personally think that we as riders should help one another whenever the opportunity presents itself, if we want continue to foster the sense of community and brotherhood that draws so many people into ownership in the first place. My garage is always open to anyone that needs help and I don’t ever change any one in hopes that they will “pay it forward”. My 1199 is about due for valve adjustment and the valve cover gaskets are leaking like a siv. So I’m keeping an eye out for your next vid.

Also you can triple double or triple the servicing costs. I work at a triumph dealership and we try our best to help customers out on their bills but it is still a shock to a lot of folks! Most dealers aren’t trying to rip you off they’re just has to be enough money to give everyone a piece of the pie, even if the folks at the dealership are getting a much smaller piece of the pie. But c’est la vie, 🤷🏻.
