Try eBay or a motorcycle part finder site And on the problem of it reoccurring difficult to say as need to know what damage was caused to piston and valves Was it just one rocker arm that broke or is the other damaged did the timing jump and piston hit open valves driving them up and breaking arm and damaging cam shaft lobes You really need to find out why and how it happened As it may require a complete timing system replacement on that cylinder cam shafts , rocker arms , valves ,drive sprockets top and bottom , drive chain and a piston

I had something similar on a 600cc Honda. The choke cable had been caught under the tank and didn't retract properly. However if the bike has been sitting for a long time start by checking the plugs, then the air filter then the fuel filter if its easily accessible. Ok that's the obvious stuff out of the way fuel starvation can occur in older Kawasaki's where the carbs ice up. But I suspect if your bike hasnt been run much either the plug leads or coils are shot or one or more of the main jets in the carbs is blocked. Hope this helps Tim

it depends on your Wt.. I put mine at # 2 and I Wt. 220 lbs.

Find exactly where the fluid is leaking. It could be simply a fractured line. Is your oil okay? If not diluted with coolant then unlikely to be the head gasket. Not down on performance? Again unlikely it is the gasket.

Hi Small vacuum tube goes to the inlet manifold, safety device to prevent fuel flow when not in use.

If you literally **** on it it will start and run!!

There is one sparkplug at center front of engine and one at center rear. They are fairly easy to change. Just follow your spark plug wires. Did the vehicle set up for a long period and did you use a fuel stabilizer in the fuel.

If it idles and revs fine, then make sure there is no binding in the throttle cables. Turn your handlebars, right lock to left lock while twisting the throttle open to closed. Everything should operate smoothly.

Jumping out of 3rd gear on a 250 Venox is a design fault. The prongs (3 of them) on the sliding gear that hook into the slots in the fixed gear giving you 3rd gear ratio, are 2.5mm (two point five) too short. The only possible solution is to make them longer. I did just that, making very sure shut all three prongs touch and transfer power when in gear after allembly, that is crucial. I did that mod 15000km ago and had no problems. Watch out for a hidden bolt under one of the timing chain tensioner/slider when splitting the box.

Either the clutch plates are stuck together (unlikely) or your side stand cut out switch or your clutch lever switch (on handlebar lever if fitted) is faulty

I think you're correct in guessing it's a head gasket.

sounds like the fuel float to me you could have condensation or trash in tank or you may need to change the float there are no fuel filters on the Venox 250 it also could be the vacume line these are both under the tank and are easy to get to and remove the tank

It's the idle speed adjustment. Forward (clockwise) for faster/higher idle, back for slower.

there are no fuel filters on the Venox 250

if you email mad matts at [email protected] with the make of bike and year he will tell you what the right battery is you might have to give him the batteries dimensions

There is no fuel filter, never one used in line. The only filter is the fine mesh nylon screen at the outlet inside the fuel tank of the gas supply valve.

This is usually the symptom when water has condensed in the gas tank and made it's way into the float bowl. Drain the carbs. No guarantees, but no money is spent on the suggested fix. Hope this helps.

I have the exact same issue. Did you solve problem?

Possible failure of the ignition unit. you need to trace the voltage to the coil, the trigger voltage if absent then the ignition system is defective. Check the input and also the 12 volt to the coil , if coil is heating it can be faulty.
