Okay hers my situation. I put my polaris 570 in the drink and blew it up, so I installed a 630 big bore kit ,,, it worked awsome and as it should

a few weeks ago, I mab up a semi stealth snorkel for it, and now me, and my buddy have came to the mutual agree ment that when its topped out it feels like it could use a bit more fuel, bike would do 115km with the 630 bb before snorkel,,, and now it goes about 108 ish

so my question is. do you think the snorkel kit, (which deffently has more air flow) is making the engine run lean and want more fuel. An if so, can i tune it up or do i have to buy an optimizer, and if thats the case any recomidations on the optimizer
