It's bigger, better performance. It will run with others, but I would stick with the stocker. That and the exhaust is what gives the 88, more "juice" than the other 2 strokes.

Re: 88 marathon carburetor question
Don and Morgan are right.
The pre-88 Marathons used a Mikuni BV18 carburetor, while the 1988 model used a BV24. That's 18mm vs. 24mm, or a 33% LARGER venturi on the 88. That, paired with the 1988 only exhaust which is MUCH better, gets you some very noticeable power gains on an 88 over the older models. One post I read stated the early models were rated at 9hp, while the 88 was rated at 11hp. Last edited by 93yellowclubcar; 01-19-2015 at 09:17 PM.. Reason: Called 89 the wrong name!!! |

You know what's funny? Even though I changed it as soon as I could, I knew you'd probably seen it and would say something. If you're like me, you've probably been called worse, huh? |
