Hi, i currently own a rotax max pre evo intrepid kart that i rebuilt and got track ready last year. I dont have a massive urge to race atm just want to do test track days as the closest track to me about 1.2 hrs away. I live in Ireland and the rotax is a very popular engine. But i have a second intrepid chassis laying up in storage and id like to put a 4 stroke engine on it. Ive been trying to find the most popular engine used here in ireland but cant find any.
4 strokes whilst alot less intense and slower can provide a more fun experience, less maintenance and teach people technique and so on. I know pro karts were a thing back then as i owned one as my first kart when i was 12 or 13. I was thinking of putting a gx390 on the kart or is this too underpowered? Will i need to mod this engine for it to be of any use? Ive seen the new tillotson t4 chassis and engine on offer. This looks good but i dont need the whole package. Im sure i could purchase the engine itself but id like to know what guys in ireland are using for 4 stroke racing,
