Haven't ordered yet, just patched then up with windscreen silicon, no problems so far. I have 2 problems with making up pipes, firstly, the 316 needs a compound bend, so lots of elbows, which leads to my 2nd problem, creating airtight joints that won't tear open when the engine moves on it's mountings. The same applies to the hole for the crank case breather connection. Still doing some research on the joints, so not a lost cause yet.:fencelook:
