RRV has poor fuel efficiency and reduced power
I brought my 97 'Blade back to life a couple of years ago, after a few years off-road. However, I notice that I now only get about 30 mpg, when I used to get about 42 mpg. I also feel like the power is reduced from what it used to be and there is also smell of petrol (gasoline) in the exhaust. I have cleaned out all of the carbs, and rebalanced them with a carbtune, but this hasn't changed anything. Does anyone have any ideas what might be wrong? I guess the smell points to running rich, but I still need to use the choke, except on warm days. I initially had hassle with the boots to the engine block being stiff as plastic, and leaking in air, so that I kept flicking to just three cylinders. However, I have replaced the boots, and now fire on all four. I asked a local mechanic, and he just says its an old bike, and the cylinders become worn. However, its only on about 30k miles.
Any help would be appreciated.
