What type of starter brushes on Honda Innova ANF 125 2008

2007 is the crossover year. The model ANF 125-7 is the first injected bike in Europe and was built for the 2007 model year but some 125-6 bikes may have been registered in 2007 and they will still be carb bikes.
If the bike has slatted grills over the air vents on either side above the front of the engine, it is an ANF 125-7 or later Injection model. If it just has triangular shaped air duct holes, it is an ANF 125-6 or earlier carb model.

Is the spark plug set at the right gap if the old plug is light brown its running OK if it darker or ioly its running rich or very light its running too lean

if you tune your ANF so it has more power than is legal for a learner (UK) you can get into all sorts of trouble as your bike will not be Insured, taxed or have a legal MOT (UK) not sure where you are and the laws of your country, but a unrestricted exhaust, K&N air filter, and fitting the right jets to suit the exhaust & air filter will give you more power, or you can add a big bore kit (142.5cc), but its not advisable if you are restricted to a 125, but if you dont care about laws or are using it on privete land or race track add one of these http://www.ebay.co.uk/itm/HONDA-ANF125-to-142-5cc-INNOVA-WAVE-CYLINDER-JAPAN-PISTON-KOLBEN-KIT-ANF-125-/261663079330?pt=UK_Motorcycle_Parts_13&hash=item3cec55bba2
you will also need to put a smaller rear sprocket or larger front, as the engine will have more power so the gearing will be wrong and the engine/gearbox will scream at top speed

There is no restriction on the Innova.

The engine and injection system is purpose designed to deliver high torque and high economy. A carefully ridden Injection Innova can achieve 40 miles (65kms) per litre which is far better than any other 125cc machine.

An Innova 125i will do a genuine 60 mph happily and show around 65 mph on the speedometer.
The most effective way to more power would be to fit a 150cc 'big bore' kit. but if you want to go faster a lot, sell it and get a PCX or similar and live with the relatively poor economy

Keeping all of the parts together, making sure the chain is tight when you put the rim back on, adding enough air to pop the bead back into place. thats about it
