I have a 1985 K100 RT (have had it 3 years and have put on over 30,000 miles – no other problems) and recently (2500 miles ago) instead of using a BMW brand oil filter, I used a HiFlo filter (part 14-0163, oil used – Castrol, 10W-40 and I change oil and filter every 3,000 miles). Now at time of start up the bike is smoking more than when I was using a BMW filter. Fortunately, after a few minutes the smoke goes away. Has anyone else had this problem with a HiFlo filter and what can be done to reduce startup exhaust smoke (when I use my side I put a block under stand arm). I have heard that a BMW filter has a check valve to prevent this – is this true? Advice would be appreciated.
