neilboxer Posted November 18, 2015 Report Share Posted November 18, 2015 Hi all, I just refitted my rear wheel and set my cam tensioners to the same markings each side. The wheel doesn't look like its in the center of the swing arm how would I check that? One of the snail cams does look a little battered but wouldn't have thought it would throw it out that much? Any advice ? Thanks in advance Quote Link to comment Share on other sites More sharing options...
4stroke Posted November 18, 2015 Report Share Posted November 18, 2015 Have you put the wheel spacers back in the correct positions? 1 Quote Link to comment Share on other sites More sharing options...
cascao Posted November 18, 2015 Report Share Posted November 18, 2015 Look for a chain alignment tool. The tyre can bother you Quote Link to comment Share on other sites More sharing options...

cbutler Posted November 19, 2015 Report Share Posted November 19, 2015 You can measure from the center of the swingarm pivot to the center of the axle. If the pivot bolt has a hole in it find something that fits snug (drill bit, wood dowel) and measure off of it 1 Quote Link to comment Share on other sites More sharing options...
scot taco Posted November 19, 2015 Report Share Posted November 19, 2015 A way to check if the chain is running straight is to put the bike on a stand and spin the wheel.Then check to see if the chain is centered on the sprocket or running against one side of the teeth and adjust accordingly.

lineaway Posted November 19, 2015 Report Share Posted November 19, 2015 The cam markings are a general guide, not set in stone straight. 1 Quote Link to comment Share on other sites More sharing options...
neilboxer Posted November 19, 2015 Author Report Share Posted November 19, 2015 The tensioners are approx 100 degrees out to each other, I think the wheel spacers maybe throwing it out some how. I'm going to investigate. I use a lazer level for work so I bet that would work to make sure the chain is running straight ? Quote Link to comment Share on other sites More sharing options...

crazybond700 Posted November 20, 2015 Report Share Posted November 20, 2015 (edited) Theoretically the swingarm can be bend, than the wheel should still be in straight aligned with the front sprocket (so the wheel would be not straight in the swingarm. 100 degrees is a lot. Sure those nails are not damaged, or the swingarm is damaged or so? Friend of mine had the part of the swingarm where the snail sits on damaged. The only other possibility I can think of is the wheel is not centered on the hub, or the tyre is bend (give it too much air and it will probably sit centered). The hub should be perpundicular to the front sprocket, so the sprockets are lighned up propperly. The hub is set slanted most often because the chain is on one side so it goes heavier to slide it.

fantic240motor Posted November 20, 2015 Report Share Posted November 20, 2015 You could align the rear wheel with the front by using two straight edges. It's an easy way to check both wheels are parallel to prevent it crabbing. Two rips of ply wood or MDF work well. Stand the bike upright with the tyres fulling inflated. Use some blocks to raise the straight edges off the ground a few inches then push one straight edge against the front and rear wheels on one side and then same the other on the other side. The front wheel will find it's straight ahead position between the two straight edges and the rear will show up if it's not straight ahead. You can then adjust the cams to find perfect alignment. Once the wheel is tight you can mark the cams with a sharp punch for future reference. As mentioned above good to visually check chain alignment. It must run dead true.
