I have a 2003 Vento Trtion R3, 100cc. Mexican made I guess. Does anyone have a service manual that can be e-mailed to me so I can download and print. Vento USA wont provide a manual for Mexican made scooter. And I dont speak spanish when I called Vento(Mexico)and tried to order one. And any performance mods/ideas would be appreciated. And Thanks in advance for any assistance....Steve

Cant believe no one has any info, let me know...Thanks

The link below is for an on-line service manual I found for the Vento Zip R3. I don't know how much will apply to your model, but I thought I would pass it along anyways.

Thanks I'll check it out, but I think I've already seen that and they are not the same. I tried to get 1 fro Mexico but I guess my e-mai wasnT in Spanish. and I got no response. and Vento California offered no help at all...Steve

When it comes to customer support Vento has a lot to learn. Shortly after I got my Triton Li I had contacted the company as my machine didn't come with an owner's manual and I was interested in obtaining a service manual as well. I was advised to call back as they were currently none in stock. After a couple of months I called back and got an answering machine. To date my message hasn't been returned. A follow up e-mail went unanswered as well. Best of luck in your quest.
