One larger hole. More concerned about the flex pipe length recommended for the pipe and motor. I emailed RLV for help but haven't heard back yet. ThanksIf its a two hole outlet , might cover one or reduce by half if a oval .

Thanks. Where did you find the chart?.The chart show 9.5 .
Too short adds heat to the engine .
Research wet line in the search function .
The magnifying glass upper right
Don't seem to see it.The link I sent you.
The 2 cycle section .
Help us out . what size is the proper outlet hole .I spoke with a tech at RLV and he said it would be fine with the proper length flex and a restriction plate that reduces the exhaust hole to the proper size to be used on a kt100. Which he provided. So . I'm going with that.
