  1. Hey gang getting ready to button up a tv200 engine...we're putting a Mugello kit on it with a 28mm dellorto and a BGM/MB box pipe... nothing too crazy but looking to get some usable rallying power. Looking at the gearbox, the TV200 is really tall...4.45:1...ideally I want to be around 4.8:1 (thanks Mike for the info)...so using one of the online calculators it looks like if I go to a 47 tooth crown wheel and a 14 tooth front sprocket I will be right there at 4.87:1 first of all, are there any concerns about using this combination of crown wheel and sprocket? do I need a specific chain or is the original chain ok? Would I need a pull down type tensioner? Are there any other performance/use concerns I should be aware of? Lastly, does anyone stateside have a 14 tooth front sprocket? (I looked at the usual shop sites..nothing I can find) thanks in advance!
