I just bought a 2014 xf high country when I bought it it didn’t have a primary clutch so I bought a new primary clutch and I went for a ride when I go slow it doesn’t bog but when hit the gas it bogs allot the belt it a bit loose but the shevs on the secondary are closed all the way so the belt it maxed I also tried another belt and a secondary off a m8000 and messed around with the spacers on the bolt for the secondary the belt is still a bit loose
