Hey guys Iâ€™ve been riding the new bike for a couple of weeks now, and am absolutely loving it. Can't wait to go on the learner's ride in a few weeks! Itâ€™s my first bike, and as a result a couple of new questions have sprung up regarding the RPMs and chain: 1.) Iâ€™m worried that Iâ€™m over revving it. Itâ€™s got 2000km on the clock, so itâ€™s out of the break-in zone, but for the first week I took it pretty easy on the throttle. As a result I found the performance fairly lacklustre. However, in my second week, I started to really push the RPMs and to my surprise found that itâ€™s got decent power when the high RPMs really kick in. But how do I know when Iâ€™m pushing it too high? To get this nice boost of power, the RPMs seem to be really screaming â€“ but is it just that Iâ€™m not used to the high RPMs of a bike? 2.) I finally got the ownerâ€™s manual. Let it be said that Iâ€™m not the worldâ€™s most experienced mechanic. In fact, Iâ€™ve never even done an oil change. I checked all the levels on the bike (oil, brake fluid, coolant) and then checked the slack on the chain. Uh oh â€“ itâ€™s got about 45mm of play, which is apparently too much. But reading the instructions to tighten the chain seemed a bit too hardcore for me â€“ is it within the realms of a non-mechanic, using only the tools included with the bike, to tighten the chain? The first part of the instructions seemed fine, but then it mentioned things like the string method and checking the drum brakes, and I was lost! Hope you guys can help with some basic info!
