Leaking oil from a pipe and running really poor

Check for burst or leaking fuel lines. Check the rated fuel pressure recommended by manufacturer. Most fuel injected cars have standard pressure below 5 psi. Check the fuel pressure regulator too. Fuel pressure too high can cause injectors to leak and cause overflow and poor combustion.

any smoke from the tail pipe.if it is ,it might headgasket leaking from inside the engine or the valve stem.check the PCV system ,it might block it & oil is going to intake system.check the PCV system & the vent hose first.

hiya sounds like your float in the leaking carb is sticking. this will cause the problems you have. check and clean float system in carb, check for leaking float too.

FYI This has just happened to me.
Bike has been stood for a few weeks and i started it. Noticed the temp was unusually high (105-110) so switched off, checked coolant and it was dry.
I topped up and noticed the coolant leaking from what appears to be a hole in the engine sump casing.
Im a fairly fast worker and i managed to remove the entire exhaust system down to the header pipes and drop the oil and remove the sump casing in around an hour.
It might take longer if you don't do much mechanical stuff. (I'm just a hobbyist btw not a mechanic).
It turns out that the hole in the sump casing is actually linked to a coolant overflow pipe internally. So don't worry coolant is NOT mixing with your oil (and therefore oil is NOT mixing with your coolant!)
So obviously there is something more to this than meets the eye.It turns out that on all Pre2006 R1's the Water Pump is internal and if it leaks, You guessed it, It used this overflow pipe to stop the coolant mixing with your oil.
This is where my mechanical knowledge ends and i will be taking my bike to a real mechanic to swap out the water pump for me.
The good thing is, if you already remove your exhaust system and drop all your oil etc this will save around 1-2hours of labour at the garage!When they've fixed, get them to replace the oil and filter and leave them your exhaust if you like to fit and they can run it up and test it before returning to you working:)

Its a breather pipe - check oil level & air-box for excess oil

Sounds like a combination of leaking fuel tap and old fuel.

When you park it overnight or longer, pull the fuel hose off the carb , and drain the carb bowl.
So when you next ride it, reconnnect the fuel line, turn on the fuel tap long enough to fill the carb, 10 secs,then turn it off to start the bike, turn it back on when the bike starts.
even if you replace the fuel tap this process can help.


I have a 91 wr still sitting under the house from younger times, and yes very good bike

The oil leaking from the voltage regulator connection has nothing to do with the bike not starting. To stop the leak, you'll have to go into the primary and pull the stator out. Pull the plug out of the hole from the inside, clean the oil off the plug and out of the hole. Then, put a good coat of RTV on the plug and push it back into the hole. Put the bike back together.

As for the no start problem, since I don't know anything about the ECM equipped bikes, I cannot help you there. Sorry.

Good Luck

Part of the engine's compression is getting past the piston rings and going into the crankcase. The crankcase is letting the compression out via the vent pipe as it should. A little bit of the oil splashing around in the transmission is being carried into the vent hose by the compression. The vent pipe is leaking onto the roadway soon after you start to ride ( as the revs increase ), you just didn't know it until now. When you stop riding, the oil that is still in the pipe is what leaks onto your driveway. Your bike is big enough that you don't notice any loss in power. The repair is a bit expensive; new pistons, rings, boring the cylinders, a valve job (since you already have the head pulled off, now is a good time to do it ), and the labor charge. Unless the leak is really offending you, I would just park the bike in a spot where the oil won't stain the concrete and leave my money in the bank.

The CB200 may be able to do better when new however being only 200CC and the age of the machine this may be its best. You could check the compression to see what you have; if these are lower there would be some lose of power there. Also the carbs may need a once over, this too may get you more. However I would not expect to cruise at 65MPH with a 200CC, she'd be running pretty hard. The redline may not be unitil 9300RPM however the engine lacks the torque/power to push it beyond where you're at now, the 9300RPM may be used to get you there. In theory if you could take it out in max. gear to 9300RPM the bike would do @ 110MPH; many 750CC bikes cannot do this.
Great bike though, should treat you well, enjoy the ride and the gas mileage...

More than likely the majority of the problem is related to poor compression pressure. When was the last time the engine was re-built (a new top end)?

I would suggest evaluating the condition of the piston, ring and cylinder. Replacing the piston and ring and won't set you back much if the bore in the cylinder is good and it will definately perk your bike back up.

Clean that air filter too - a plugged filter will cause the bike to run rich, too.
