Group 8 of 9
The exhaust and silencer, the gas test at idle and the horn.
4 items: 4 type A (one fails the test).
The exhaust has no breaks, holes or loose joints and is fully fitted. A small hole that is part of the design is fine.
With the engine running, listen and feel (carefully) for puffs at the joints and look under the motorcycle.
The silencer is fitted and sounds normal; no straight-through pipe, whistle or device made to make noise.
The check is by ear: an exhaust that is clearly louder than standard is a fault.
Warm engine at idle: no blue or black smoke, and the engine idles steadily. The centre measures CO and HC at idle.
Ride for ten minutes, then let it idle. Blue smoke means burning oil; black smoke a rich mixture. A 2-stroke shows a little light smoke. The limits for your engine are on The inspection.
The horn sounds clearly when you press the button.
Press it with the engine off and with it running.
Go through what the inspection looks at, group by group, mark what is wrong and send the fixes you want to DASA MOTOS on WhatsApp or by email.
