Coolant going through carb bases.

Postby Csj992 » Wed Sep 21, 2016 9:43 am



I was wondering why on my 1500 does the coolant run through the base of the carbs. Everything I thought I knew about carbed engines was the cooler the mixture the better it ran. I read that they did it to heat the carbs up faster. I was just wondering if the heated carbs could be contributing to my hard warm starts? When cold the bike fires right off. I did vent the cap which seems to help.


Getting too old to have so many old vehicles. :P

My opinion is they engineered it that way because of the long length of the intake runners, not because it's a boxer motor though that does contribute to the runners having to be as long as they are.
