Hi everyone, a post for all of you handy with spanners! This post is also\nin the Classic Bikes newsgroup, so if anyone thinks it looks familiar, it's\nbecause I'm getting desperate!!\n\nCompletely rebuilt motor on the RS, yet it still sounds like the big-end has\ngone, despite having a rebuilt crank. Starts and runs ok, makes no\ndifference if you pull the clutch in.\n\nDid notice when I took it for a run that it seemed reluctant to rev\nproperly, I put this down to the fact that it hasn't been used in ages, so\nmaybe a blocked jet etc....question is, does anyone think the two are\nrelated???\n\nAny ideas?\n\nRick.
