Old man Posted June 3, 2019 Author Report Share Posted June 3, 2019 Hi looking at a Bultaco engine similar to this ( Image ) the first letter is ? don't know then M-50129#-D-5 hidden last number with hash tag any help in recognition Thank you Quote Link to comment Share on other sites More sharing options...
feetupfun Posted June 3, 2019 Report Share Posted June 3, 2019 I think it's an Astro (model 90) and you've either misread the first number or someone has altered the number. How about you cover up your secret last number and take a close-up photo and post it up? Quote Link to comment Share on other sites More sharing options...

lorenzo Posted June 3, 2019 Report Share Posted June 3, 2019 Hi, Old man - Kart - model 5 (not 55) originally available in 100/ 125/ 175/ 200cc capacities, I believe.........?? Quote Link to comment Share on other sites More sharing options...
stevem75 Posted June 3, 2019 Report Share Posted June 3, 2019 It’s definitely not a bandido engine. It looks like it’s a model 5 kart engine. The D means it’s a 250cc and the 5 at the end indicates 5 speed. They made this engine over a long period of time so that’s why it has the mid 70’s barrel and head. They may have started production of that engine in the mid sixties and continued it sporadically over the years. I’d guess given the higher than 1000 serial number that it’s a later model produced in and around 73-74 steve Quote Link to comment Share on other sites More sharing options...
