I had the same battery issue. Changed it. FIXED!

Thanks for your explanations! :) Really informative showing actually the results/difference.

cool video. I also installed an EPI clutch kit on my 2000 Polaris 500 and it really woke this ATV up. Throttle response is better, it engages faster, and it turns my 27"swamp lites just fine. I ended up installing the mudder spring (orange) instead of the red spring. I bought the primary and secondary clutch removal tools and even the spider tool remover. I built my own fixture to take sheaves apart. I also replaced stock belt with heavy duty cvt belt. DIY so much cheaper than going to dealer shop. I found everything on e bay and amazon. :)

My 570 has the same issues starting.

Thanks.

I hate that clunking noise drives me nuts!!! Come to find out, everyone told me it's the belt. Now I believe it. Just like you said it stopped doing it, for the most.

my had same starting issue put in a ETX15L battery with 220 cranking ampe and added a second ground from battery to frame starts like it should now

Thanks for the nice review! I'm thinking about getting the EPI Clutch Kit for my 570. Did the clutch kit lower the top speed?

also did your top end speed change ?

Ya bought a 2017 and battery was low when i took it. Guy just says you got a trickle charger right? First thing i did was get a battery tender but i noticed it doesnt hokd a charge long. Oh well ill buy a better one. Still like this quad. Was a really good deal.

Hey ther, another question. How many spring are supposed to come in these kit. 3 ?

Get a battery for a 700-800,325-350 CCA.I run mad lights,2500 pd winch and boom box with amp never had a problem starting even in coldest weather

is it smoother when the clutch engages ? btw seems like all of the 570's have undersized batteries, my 2017 does the same, what size cranking amp battery did you get ?

Question why wouldn't you want to install the spring that would allow the unit to engage at lower rpm's seems like that would give better throttle response??

I love the result…more snappy, yes…you lose some smoothness. Isn’t that the point?

If i have stock tires on the 570 sp is it worth getting a clutch kit like will i gain more power

Good video!

Yep their batteries can test ok but still be bad, but I should have done what you did and replace it with a off brand

If yours is anything like mine the Polaris dealer didn't charge the damn battery till I was there to pick up my machine, they knew I was coming but didn't charge my battery a full 24 hours like they were supposed to. That made my battery extremely weak, I will be replacing that battery next week lol I hate Polaris, crappy business practices, customer support, crap aftermarket products etc etc etc. I wish I had went with an Arctic Cat Wildcat trail

You said this was on the non ebs model right? what would happen if you had the ebs model and used this clutch kit in it?
