pilninggas Posted September 7, 2010 Share Posted September 7, 2010 iv got an yamaha 1000 exup will it make much diference if i take exup valve out as it rattles like a chain is loose and driving me up the wall or is there any way of stoping it rattle if you do take the valve out, be ready for knackered low-end performance. The valve shouldnt really rattle, however in my experience it can be that the flap has some play in it, you can try shimming it with some washers (copper washers and some high temperature grease), though it can also happen if the cover has not been put back on correctly (happens sometimes if the bolts sheared).
