I just added a snorkel on my 07 big bear now when it first cranks it spits and sputters until it warms up then seems to run ok if it sits for more than about 15 min. it does it again. any thoughts on what i need to do?

 

With the snorkel installed the airbox is either getting to little air or too much. If you used 1 1/2in. pipe and its over 4 ft of total lenght it may not be getting enough air causing it to run very rich. If you used 2 or 2 1/2in pipe then its getting too much air and running lean. It will need to be rejetted either way.

 

did you ever get this figured out? if not I have a very simple solution for this that does not require messing with the carb at all.

 

restrick the air coming in that will slove your problem
