Default Bogging in the sand

Bought this quad used, previous owner bought it new. He was an older guy he kept it very clean and added all the parts in my sig except the tires and rims. My first real ride was to the dunes after i put the paddles and rims on (first time i have ever ridden with paddles). The quad bogs a little when its not being revved up, its the worst while trying to take off in 1st. The engine seems to run perfect otherwise. I'm thinking i should change the sprocket size or it could be the jetting. What size sprockets? Front or rear or both? You guys are the experts, help please!

If it bogs when not revved up, then rev it more on take off. It takes alot more to get going in the sand than on any other surface. It could be a jetting issue, but its most likely the case that you just need to give it a little more of that go juice.

I just really dont like revving the crap out to take off, im kind of
afraid im gonna burn the clutch out, It acts more like a two stroke the way it like top end. It cruises in low rpm in 2nd,3rd,4th fine but when you try to roll on the gas it starts bogging, i have riden many other 4stroke quads and dirtbikes just never with paddles and i have this problem

the more i think about it, i think a sprocket change will solve my problem. the motor doesn't bog any other time through powerband or other rpms really. i don't really mind losing some top end speed. any ideas on sprocket sizes front/rear?

is dropping two teeth too drastic? preferably i would like to change it once and leave wether i ride on dirt or sand. i would like a little more acceleration vs top end speed anyway. i just dont like having to hammer the gas and drop the clutch to get the tires spinning to start or medium gas and feathering the clutch like crazy in the sand. maybe down 1 in the front or up 2 in the rear, does that sound about right? any pros/cons on front vs rear change? sorry about all the question i just like to make the right decision when buying parts so i'm not disappointed with the result feeling like i wasted money.

the 04/05 hrc cam is a top end cam, if you want its power you have to get into it's rpm range
wind it up and let it go, the sand adds resistance to everything. Just go try to run up a dune and your body will be bogging lol
drop one tooth in front will help but your cam wants to be rev'd

i think i'm going to drop a tooth in the front, i noticed honda equipped the 06+ with a 13 tooth instead of the 14 tooth. what size chain will i need for the dropped tooth and stock rear end setup? i appreciate all the help now i just need a deal on a 13 tooth steel front, 38 tooth steel rear, decent chain, chain breaker, and i might as well throw a case saver for good measure that can be here thursday.
