=== Turn Signals === | |||
Any single-wire turn signal (chassis ground, hot wire) | |||
with a male M8x1.25 metric threaded connector should fit | |||
the bill. | |||
=== Fuel Petcock === | |||
The zinc fuel petcock tends to crumble into dust after 25 years or so, | |||
and will need to be replaced. | |||
You can replace it with a metric M16x1 female thread petcock, available from many | |||
Italian and German dirt bike suppliers. Unfortunately, most of them | |||
will not ship to the USA. As of this writing, http://www.trebes-motoparts.de | |||
carries several compatible [[Bing]] M16x1 petcocks, and will ship to the US and Canada. | |||
Use Trebes-Motoparts part number 000.009.437 for a Bing M16x1 petcock with a | |||
built in fuel filter. | |||
== Del Orto Carb Adjustment == | |||
The idle screw impacts starting the engine from a cold start, | |||
and is a very tricky adjustment. If you get it wrong, your engine will | |||
not start at all. | |||
It can be reset by turning it all the way in, then unscrewing it | |||
'''two and a half turns'''. | |||
Any further adjustment should be in 1/8 turn increments. It's | |||
an incredibly sensitive adjustment screw. | |||
== Oil Change == | |||
Many 1973/1974 models have an unfortunate design flaw that has lead to the | |||
death of many a kickstart spring. There are '''two''' bolts on the | |||
underside of the engine that look like they are the oil [[drain plug]]. | |||
The bolt immediately under the kickstart lever is the '''kickstart stop''' | |||
bolt - this is what keeps the kickstart from completely unwinding. It is also | |||
the only under-engine bolt visible if the skid plate is installed, as the | |||
'oil drain hole' in the skid plate is in the wrong place, and the | |||
skid plate covers the '''real''' oil drain. | |||
'''DO NOT REMOVE THE KICKSTART STOP BOLT''': You will have to take the | |||
right side engine cover off to fix the kickstart if you do! | |||
Remove the skid plate, and you will find the '''real oil drain plug''' | |||
in the rear-middle of the engine. Unbolt, and drain. | |||
(While you're waiting for the oil to drain, now might be a good time to | |||
make a hole in the skid plate for the real plug.) | |||
Refill the engine with 48oz of SAE 30 Weight Motorcyle wet-clutch compatible | |||
oil, and you should be good to go. '''DO NOT USE DETERGENT MOTOR OILS:''' they will bind up your | |||
wet-clutch. | |||
== "Breaking" the Clutch Plates == | |||
If your clutch plates have seized, you can try to unstick them by: | |||
# Setting the keyswitch to "OFF" | |||
# Squeeze the clutch level firmly | |||
# Kick the kickstart a few times | |||
If the clutch is frozen, you should feel some resistance, and hear the engine go ''blub blub blub'' a few times. When the clutch plates come free, you will feel almost no resistance on the kickstart, and the engine won't make a sound. | |||
