A coolant leak is no laughing matter.
If the leak causes you to lose enough coolant it won't take more than minutes to turn a perfectly fine high performance Italian engine into grist for a recycling mill. The cure is to break out the tools and turn my half of the garage (the other half belongs to Susan) into a Vespa emergency repair bay.
The bad bit is that getting those curvy plastic panels off the bike requires patience, along with some coaxing, cajoling and some light doses of soft cursing. The good bit is that the whole thing can be managed with a simple Phillips screwdriver and a pair of needle-nose pliers. The large-frame Vespa GTS has a lot going on in its innards, and that means the job is about double the complexity of disassembling the air-cooled small-frame Vespa LX model.
This was the first time I needed to get under this Vespa's floorboards. The job involves removing the following body parts and some other bits and pieces a stock Vespa won't have (hence the asterisks*):
- The Piaggio badge.
- The kneepad hatches covering the left recess with the alarm connector and the right engine coolant cover.
- The HeatTroller heated grips control.*
- The horncover.
- The glove box.
- The floor rack.*
- The battery cover.
- The crashbars.*
- The side fairings below the cowls.
- The two small covers at the front end of the fairings.
- The floorboards.
- Removing the glovebox; as usual, a brilliant YouTube video from the collection of MVer Mic Bergsma.
- Removing the aforementioned, plus the two halves of the headset cover and the floorboards by the famous Robot, mechanical guru at ScooterWest in San Diego.
- Excellent photos of the same steps by Jess Devine of ModernVespa fame.
In short order, all those pretty bits litter the garage floor...
The next day I returned to my bike in the garage at lunch time and was thoroughly pleased to find the garage floor nice and dry.
helping hand from ModernVespa, as usual.
One more repair to come, stay tuned.
