I have an old suzuki enduro from the 70's. I have no clue if the engine even works and quite honestly have no interest in playing with it. I want place this engine inside the bike. http://m.ebay.com/itm/250654515200 My question is if I do this will I still be able to street ride this bike and what will it's high speeds likely be? Will it be able to sustain those speeds for a while? Also am I going to have problems attaching the stock exhaust to this engine? Will any carb for s 250 cc engine work?
