I recently purchased new Hero Honda CBZ Xtreme bike. I am facing following problems:- 1.) When i engage first gear and raise the speed releasing the clutch, i feels like vibrating at the gear box or just below the petrol tank. 2.) The bike firing is not like other CBZ Xtreme bikes or a new bike(clear,like a newly purchased bike). 3.) Bike has a lower mileage(30-45km/lit).

SOURCE: Petrol smell

looks like your carburettor's giving out a rich fuel mix there or you've forgotten to turn off the choke get you carb tuned or jetted for better mileage (at a loss for speed - acceleration & power... if that's not important to you).,,

SOURCE: bike starting problem

ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine.

Please rate this solution. Thanks!

SOURCE: clutch not engaging cable feels very slack

ok, three different possibilities here. first, you replaced your broken lever with a lever that has the hole for the cable end a little closer to the perch, and you dont have enough range of adjustment to tighten up the cable. this is probably the least likely scenario, since you need a very signifigant change in the lever or perch assembly to throw your adjustment off that far.
second, your cable may have frayed or just broke. follow the clutch cable all the way to the engine, and keep an eye on the arm that it attatches to. it should move when you pull the lever. if theres no movement, then your cables broken or frayed.
if you can see that the cable is pulling on that arm, then your problem may be internal. also less likely though. but as a last resort, if you have the mechanical knowledge, then check behind the pressure plate for anything that may have broken in the assembly that pushes the pressure plate outwards. IM not too familiar with the kawasaki's design, but there may also be an adjustment screw and locknut right in the center of the pressure plate. tightening up just a little usually solves this isssue.

SOURCE: with the bike in gear and the clutch engage, the

Clutch discs are stuck, put the bike in gear, not running, pull in the clutch and push the bike back and forth to break the clutches loose. Once they break loose start the engine put the bike in gear, hold the front brake, and slip the clutch a little to remove any built up or stuck crud on the plates.
