Ugly Ugly Ugly. Those conversions were for a day that quads weren't so available. I do see your point though...
We really just have to stop screwing around and nail down some 4 to 3 conversions. MR ATC had started one but that seems to be taking a long time. Tossing a newer motor in an old chassis is great but still uses 20 yo parts.
There is alot of talent on this board and everyone has something to add. I don't think it will be long before we come up with something that will let us grab a used 450R for 4K and some custom parts for another 2K that gives us what we all want.....A reliable, fast, new and good looking ATC.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
