i think only the dt200. but i may be wrong
easy up grade would be a air cooled 2 stroke... 80s cr yz kx rm 250 or 400-500 2 stroke... will need some fab work but sh*t...
im thinkin about trying to do a 2 cyl sled motor in a trike
depending on the trike, that may end up being a big pain......why not just use a shee engine
blaster engine......my bro has a complete engine he'll sell. its ported.....just a thought...really 200 isnt bad to fix it....to be quite honest. you'll spend more on a different engine than you will to fix that one im pretty sure.....not a whole lot of good running engines goin for 200 or under...What motors bolt in to a stock blaster frame?
