Hi, Steve, I would love to help you with your engine or chassis noise but I just loaned my brand new pair of listening ears to your local dealer's chief technician so he could take your bike for a test ride and give you his professional opinion and estimate about your noise and repair cost. If you are a little short on "DRACHMA" and a Dealership is not on your list of fun places to visit then perhaps the list below will help soothe your worried mind so you can make an informed decision.

When a municipality has a Water Main break the work that follows introduces so much debris into the adjacent lines that most filters are coated, overwhelmed and can't stop the sludge that is being forced through them and you will find the harder compounds, ie: calcium deposits, concrete particles & actual rock debris, although microscopic in size, in the water control solenoids of the new appliances we have today. It only takes one tiny little hard particle to jam the plunger in a solenoid and stop it from opening or closing. I feel confident in saying that your machine is not damaged but the clean-out of it may require a Technician that the City is Libel for paying, to fix your machine if the task is too complicated for your skill level. As with any new machine, cut all power to it and let it rest for ten minuets before powering back up to allow it to run it's own diagnostic troubleshooting program. It might give you a Fault code that will tell you exactly what's wrong and it could even clear the fault itself. I hope that helps.

then choose "RESTORE COMPUTER TO EARLIER TIME' and follow dialog. If system requires to make backup first then authorise it to make backup, you may need it later.
My first question is, can the engine idle ok. If yes, then cutting out at intersections may well be heat soak from the engine boiling off the fuel in the float chambers. Try fitting anti-percolating blocks between the inlet and the carburetor mounts. These are red fibrous blocks machined to the same tolerances as the carby bases.
The alarm you hear may be the overheating alarm... but, if it is, it won't run too long with it on before the engine locks up...Is there evidence of water coming from the witness hole in the back of the motor? Good.. otherwise,, you may be hearing the low oil alarm..or the oil pressure alarm...My bass boat oil system alarm goes off every time I crank the engine..but it uses oil and runs great...(been doing it for years - I am too lazy to clean the sensor in the oil tank)
The RPM and faster alarm is something that puzzles me?
