so my free Indy 400 that i got this year only lasted about 2 weeks. its on the verge of blowing up. i drove it about 50 km and it started to act up. i took it to a guy to clean it out and found out that the carbs were set to too lean. and im guessing that is bad? he says it could go at any minute. so im in the market for a new one. there is a 1992 MX 470 for sale for 1200 bucks from a dealer. what do u guys think about this topic? is that sled good or bad? and can my sled blow up from running to lean?
