When you rev the engine and does not go over 3000 rpm is this in neutral or when driving in gear? Some vehicles have a rev limiter to not allow rpm over certain point when in neutral gear but is typically not limited when driving vehicle. This sounds like a very low rev limit but not abnormal if you can get engine to rev higher when driving. You call a drifter so truck must be non US market. Is this engine a 2.5 liter diesel 4 cylinder motor. Might just be your top rev and speed if this is the case.
Check it's not a tight accelerator cable issue & that there's some play in it at the throttle grip. If there's none, it might just be a case of slackening off the cable at the adjuster where it goes into throttle grip on the bars.
Assuming that's okay but the engine still revs high on idle speed, you'll have to lower the tickover by removing the left middle fairing to expose the engine. If you trace the accelerator cable, you'll see were it sits between the carbs or throttle body if your bike is fuel injected.
There's a tickover screw which will have to be turned out anti-clockwise to lower the revs.
It's not really a hard job to do if you know a bit about engines but if you don't, give the job to somebody who does.
First remove the airbox , look into the carbs and open and close the butterflys and the gap when closed/tickover should be just visible ! If more than 2 mil then adjust less gap ! Do they close automaticly or do they stick open ??
Pump up the fuel primer until hard to pump any more , try and start the engine with a little throttle advance and when started you should be able to reduce the rev's ( might have to slightly adjust the tickover so its about 7-800 rpm ) !
If you still have the problem then the carbs and ignition and possibly the crank seals need cleaning or setting up correctly !
Speak with your lawyer and get him to sue the company you went to as the engines not for use and see what the company says !
Have you checked the throttle is returning to tickover on the carb ? cable sticking ?
If it is on tickover and still high reving then you could have an air leak after the carb , check the intake manifold , crank seals could be worn and this will let the engine rev by its self ! fuel mixture correct as if its 2stroke a lean mix can do this as well ! ??
It sounds like you installed a new carburetor and the problem remains. You may have a vacuum leak between the carb and the engine allowing in too much air and causing a lean fuel/air condition leading to high revs. Check your vacuum lines for cracks, check your carb holder for cracks or gaps, listen closely for an air leak. Replace any cracked lines or carb holder with new, or a temporary fix may be done by sealing the carb holder with a silicone adhesive to stop the leak.
