Things to watch out for...

As with almost any machine ever made the Runner does have a couple of gremlins. However all the ones I have come accross and herd of are easily cured.

Exhaust-every runner owner will tell you about rusty exhausts. It is always, however, surface rust and I have never herd of a hole caused by rust on a runner exhaust. Cure-take a few hours on a sunny day to sand down your exhaust and paint it. See section 4 in the servicing section.

Sticky throttles-Poeple dismantle all sorts of things to try to solve this when in fact its just the rubber grip expanding and pushing against the bar end, in every case I've herd of including my own, its simply a case of removing the silver bar end and adding a couple of washers so it sits a little further out.

Indicator switches-Electrics are not the strong point of Italian vehicles and the Gilera is no exeption. The culpret is the tiny spring behind the swich which has a tendency to jump ship leaving it difficult to make contact with the left, right and cancel function. This will be fixed straight away under warrenty and even if your warrenty is up a new switch is only about 5.

Rear lights-electrics again, this time Gilera have forgotten that not every country is as sunny and dry as Italy resulting in the rear light lenses having no water proofing at all. This allows water in to the brake light bulb and can corrode the connections. You can either keep an eye on the connections scraping any rust off them or buy some type of stick on rubber window insulation to put along the top of the lens.

Stickers- the rubber 'Runner' stickers on the side of the 2001 runners are useless. A few weeks and a couple of washes later and they will fall off. No real cure, you can glue them back on or not-up to you really although they will be replaced under warrenty believe it or not!
