October 9, 20205 yr 2003 sherco 290 I have discovered a helicoil repair on one of the two threaded holes that attaches the exhaust onto the cylinder. This repaired hole can accomodate a 25mm long bolt when the exhaust is in place. The standard size is 20 mm. By drilling in the extra depth could the repair have gone in far enough to reach a port or is the cylinder solid at the front and I have nothing to worry about? The cylinder is off for a replate just now so I cant look to see if this is the reason it threw out the water. Edited October 9, 20205 yr by misterroy
October 9, 20205 yr Did you observe coolant dribbling from the bolt/thread/stud at all? if not then all is well.
