Engine? noise Hi, I have a trange noise when the engine is on temperature. 2 scenarios: 1 While driving (espcially 3th & 5th gear) Zooming noise at arround 5500rpm Sound is a higher lower sound like you pull your finger on a diamond glass slow, fast, slow, fast, etc. Sort of 2 Slowing down (all gears AND neutral) Sounds like an electric drill/screwdriver or so at running speed to the off position. Sound equals speed motorcycle. Hope you can help me out. Or where to look for. Specialists are very expensive and i'm no newb with tools so hope to save some money and do it myself.

1 check your comprassion ratio on the cylinder , 2nd fuel hose broken or blocking the fuel 3th or fly whell key broken, start with new spark plug on 2 stroke engine 4th check for exhaust blokage 5th check the switch off and on for shortage, Fit fresh fuel,Check choke for floating the engine.

If it were slipping in 5th, it would be slipping in all gears. If your hearing noise in 5th, possibly a shaft bearing

Evert,
First, DO NOT crank this bike for now!
Troubleshooting time!

1. The other culprit could be/is the drive line - chain/front sprocket/rear sprocket. Carefully examine the area around the front sprocket where the chain rides to see if there is contact to any of the engine cases/swingarm area. IF this area is the cause you will see obvious signs of the chain rubbing something.. or the chain is excessively worn and loose and dry.
Look carefully around the drive line .... if you see nothing wrong.. then its internal

2. Drain the oil in a clean drain pan...one that can easily hold all the oil... you are going to run a magnet around in the used oil to see if there are any magnetic particles (a minute quantity of microscopic ones are normal).. you are looking for a quantity of larger chips or particles..(indication of internal damage). If a magnet does not show any unusual particles, then CAREFULLY pour the oil - SLOWLY! - through a FINE FILTER..(***** hose works well)..you need to see if there is aluminum ground up in the oil..(your engine will grind up aluminum!!) it will pack into crevices and corners...it will be very fine if it comes out with the oil. After this remove your oil filter... carefully cut it open and look for metal contamination(see above).
IF you find ANYTHING in these test, you need to find out why! This will involve a professional mechanic and some disassembly of the engine. The problem will be obvious when you get to what is causing the problem! (Either ferrous or non-ferrous should help the mechanic with the diagnosis).

Hi, did you already solve this problem with cruis control in european Ford Focus C-Max? I just activated cruis control in my car... It normaly works on 3th and 4th gear (manual transmission). On 5th gear it works only sometimes - I have to put the gas pedal down and then press the "+" or "RES" button, if I cancel selected speed and than again press "+" or "RES" button, the LED of cruis control on the dashboard flash for 1 sec and nothing will happen.

It sounds like you have what is called pre ignition knock. Have a technician drive the car and see what they think.

Hi,

There are three possible scenario's :

1, Check engine oil density, use the same engine oil as suggested by Hyundai.
2, Go for ECM reset
3, Check clutch/pressure plates

Wow, valves and other related engine noises don't care what gear you are in, they still make the noise. However your motor may be "lugging" in 5th gear which can cause a symptom of an engine related issue.
You may have an issue with the actual gearbox its self.
There is a primary drive chain that may be worn which will cause excessive noise in top gear because it is putting the greatest load on the engine. This is what connects the engine to the transmission. I think there is a tensioner for your model that will allow you to adjust the free play in the primary drive chain. If not I strongly recommend replacement because this will cause major damage if it breaks.
