I recently purchased a 2006 model Mojito 50cc, thinking I would switch out the exhaust and install a 70cc after 500km on the engine. I really like the design of the bike, but it's extremely annoying driving around (even in the city) at the slow speed I'm able to pull on original parts. Personally I have no experience what-so-ever when it comes to mecanic stuff, and I've delivered the bike to a mecanic suggested by the largest importer in the country
I was very disappointed when he said that it would be difficult to do anything because they switched to a Piaggio engine after 2005. He said it was very difficult to switch out the exhaust, and did not know of any exhausts that would fit the engine and exact design of the bike.
After a bit of research I found technigas silent pro (code # 030704011), and also found others mentioning installing this exhaust on the same engine/model. The exhaust is listed as supported on tecnigas.com.
I contacted the mecanic again, and he got hold of one of the exhaust. Finally I was hoping we'd get somewhere, but then he told me he still had real issues installing the exhaust. It didn't fit as it was suppose to, and if he'd install it this way it would generate too much heat and look really bad. I completely understood what he meant when he sent a picture of the bike (see attachement) after installing the exhaust, and he said he did not know of any other way of getting the angle etc correct - without weld and other major operations. I tried to pass on other tips from another local forum, but he still thinks this is isn't possible to do.
I've already purchased other parts (70cc + other stuff) through the same place, and what I would LOVE is if someone could give a description on what needs to be done to install this exhaust properly. Again, I'm not able to do any of this myself, I'm just hoping I can get some exact details on what needs to be done, and how - which I can pass on to the mecanic. If I end up with a 70cc with the original exhaust it's not going to do much good. And I'd hate to waste the money already spent for work and parts.
Any help is very much appreciated. Maybe someone could even pass on a picture or two? _Any_ kind of help would be GREAT. As a matter of fact the importer of the technigas exhausts even said they thought the information on tecnigas.com was wrong, and that the Mojito 50 cc/Company Cumstom w/Piaggio engine was not among the bikes the exhaust would fit.. so honestly I'm not quite sure what to think.
In advance, thank you.
