Hello wide world of bike enthusiasts. I have a small problem I was hoping I could find the solution to. I have a 1978 Honda xl175 that I've owned for about 10 years. It has been one of the most reliable bikes let alone one of the most fun. The bike has 4100 original miles, and everything else on the bike is completely original (minus oil and tubes ) But the problem is, when I accelerate quickly, the bike spits and sputters while it tries to rev up, eventually it will reach its goal. I recently added a fuel system cleaner, taken the carb off and cleaned it out thoroughly, cleaned both jets, replaced the spark plug and boot, and cleaned the air filter. When all said and done it still had the same problem!! I am becoming quite frustrated and sad seeing my precious bike having this problem. Any advice or help would be greatly appreciated. I will add pictures soon!Thank you for looking!
