Well I think I am going to give in and finally purchase a Dellorto for my 50V. First of all I would like to know where I can get one for the lowest price (I was thinking 1977mopeds.com?) Also which size would work as I have the stock long bendy intake on my fast Moby. I was thinking 15.15?
Here is the link.
I have never played around with jetting so I would not know which jet to buy. Would this fit on my bendy intake or what modifications need to be done (would I need to buy a new intake?), overall is it a fairly straightforward upgrade?
Then another matter, I would like to port my Motobecane and I would not like to mess with timing so I would follow the diagram on the wiki but only increase the width of the intake and exhaust? I have these tools in the picture below, I am thinking the one on the right would do the job?
Now, what is an attainable top speed with these upgrades. I would like to also say that my Moby has the smaller rear sprocket, call me foolish but low 40's?
