1978 Yamaha TX 750 cam timing

SOURCE: fuel for yamaha dt 125

This bike uses unleaded gasoline. At only 6.7 to 1 compression you can use the lowest octane fuel you can find. 87 in the US is what that would be around here, but across the pond the octane numbers are different. But don't forget the two stroke oil. That may be more expensive than your fuel cost.
