Question about 2008 Triumph Rocket III

1 Answer

Cold knock Hello! I have a 2008 Rocket 3. As the weather is getting colder I'm noticing a cold knock when first starting the bike. Its more prevelant on the right (exhaust) side of the motor. It quiets down after about a minute of running. I was wondering what that might be and if it can be adjusted to quiet down. I have about 3500 miles on the Rocket. Thanks, Ron LaPolla

This is just a suggest, mind you, but if its still under warrenty, I would run it by the dealer, because from what you write, it sounds like a little bit of piston slap.

That engine should be tight.

I have the same problem with mine(2008 XL883L), its at the shop right now. its my first harley so all the noises are new, my gsxr doesn't make a single tick. from what i'm told by alot of others that have the bike is that the engines are noisy, so a lot of first time riders of them think there is a problem. took it to the shop just to be sure, they said it sounds like a tappet, if it is its around $150-200. called them today, they said the synthetic oil has started breaking down where i sit in traffic (nc) but the engine itself is fine. $65 for labor and a oil change to regular oil.

Air pressure in the tires drops when it is cold (as much a 5 PSI), as you drive they heat up and that makes them fall within the correct pressure limits to turn off the low tire pressure warning. I suggest you get an accurate tire gauge and air your tires up to 32 PSI all around.

Hi, Paul if you take your bike to a dealer for a specific issue that costs outrageous amounts of money only to have the same problem 2 days later your situation is not unique unfortunately and it is a double edged sword. First, you suffer the emotional stress and frustration of spending all your hard earned "Drachma" and your bike does not get fixed. Second, comes the realization that not only are the technicians incompetent but also the service manager for not doing anything about it, this isn't rocket science, it's a glorified lawn mower engine with extra cylinders and carburetors sometimes. You need to put an end to all the double talk, dancing around the issue, and a "we don't care attitude", but how you ask, very simple you exercise the "nuclear option" go back to the dealer and ask to speak to the owner or general manager if the owner is not there, then with a straight face and polite voice you ask him/her if they can provide you with the name and contact phone number of the person at your brand motorcycle headquarters in your country that can recommend a repair facility that will fix your bike because your local dealer either can not or will not. I guarantee you that is all the grease you need to get someone to light a fire under the proper persons rear end to resolve your issue "toot sweet" For more information about your issue and valuable "FREE" downloads that you will need please click on the blue links below and for more specific information or questions at no charge please feel free to contact me at Good luck and have a wonderful day.

When it's cold out side the bike wont start. Why could that be?

how cold when this happens? is the choke adjusted properly, is the battery in good shape and spins the engine fast, weak battery is single biggest cause of hard starting in cold weather, if the battery is good it really zings the motor fast. are u using the proper grade of fuel and the fuel is fresh? using higher Octane than recommended will cause a hard start in colder weather. This advice comes from 45 years of owning and repairing my own Japanese bikes.

Whistle noise when starting cold car

its proberly what they call a secondary air intake pump - what this does is increase the air flow only on cold start up - the colder it is the longer it stays on - if the noise gets louder and you will notice - get it changed - we have the same problem over here on the vauxhall omega and corsa's - bless em got to be GM
