Hello,

having recently acquired a beautiful Vespa GTR 125cc 1971, I discover the joys and misfortunes that can be with this kind of vehicle. 1st question: could someone give me the RPG manual that year? It would already be good that I have all the doc of my beautiful Vespa. 2nd question (related to the 1st): not having the manual, I mistakenly refueled my vespa with unleaded 95. Can you confirm that this is a huge mistake because the Vespa GTR 125 of 1971 walk to the mix, is not it? Conclusion: during a ballad I was a great fright because I (I think) tightened the engine -> big blocking of the rear wheel and skid on 15m. Is this the symptom of If so, is it easily repairable? And how?

Any help will be apprecited.

I didn't find the right solution from the Internet.
