I am new to the shifters, what gears are you running? We have a blaster with a CR85 in it.

Somewhere is the 13 or 14 front and 48,49,50ish rear seem to be common.

those rear sizes sound big for a quad... sound more like dirt bike sizes... anyways your gonna have a problem with your chain guide, beatin that sprocket on the ground and even finding one for a blaster that size

I think the quoted gearing sounds right on for a stock or mild engine. Most modifieds have that size range rear sprocket. Rebel gear can get you any sprocket you want for a Blaster or any quad for that matter. Most likely, he will be using a 420 or 428 chain, so the larger tooth count doesn't meen the sprocket would be much larger diameter than the 520 blaster sprocket.

The mod was already switched over to a 428 set-up. I ahave several sprockets noe, the largest is a 54 rear, which is on it now. We will play with the gering til we get it right......Thanks guys...........And I do think the rears came from Rebel Gears.

If I switch to a 13 front what rear would I need to be using to be in the same ballpark? 14 - 54 on it now, but I want to use a smaller rear

A 50 rear with a 13 front would make it about what you have now. Divide the rear # by the front # to get your ratio.

Thanks for the advice. Now to find the 13 tooth front before the weekend. I am going to try 13/50.
