I found the plastic gastank as the only solution for off road/enduro usage. I was lucky to get one from a SUZUKI DR350. It's cheap and it fit's easily with only a few and also cheap mod's. The result is better than you can imagine. Here you can also see my selfmade alu exhaust pipe and the wavy brake disk rot...
Here they are, two purple TTR wheels with decent tyres and brake discs already on. I bought them (second hand) as spares with half an idea to supermoto my '94 Raid but have never used them. Who'll give me £250 ? Collection only from near Keighley in Gods own county (Yorkshire), BD20 postcode.
