Did you get a new oil pump?

(YES)

How abut new timing chain and guides and rubber teardrop chain tensioner?.

(All new but chain & Tensioner inspected looked good)

Did you use the paside lower balance shaft chain guide, and did you clearance it against the lower loop of the chain?

(YES)

Did you use a blank round bearing in the dside balance shaft front bore to block the oil port that fed the bshaft?

( YES-Bought Kit from PCI included Chain, Blank & Pump Plug)

Did you at least pull out the oil pressure relief piston and measure the spring?

(YES- Spring new w/ Oil Pump)

The intermittent tapping is weird! Yesterday after work pumped twice fried her up and let it warm up completely at idle. Oil pressure started at 100+ and gradually reduced to 50-60 no tapping. Put it in gear drove 3 miles in city stop and go ran perfectly! No hesitation smooth as silk. then sitting at a light noticed light tapping starting, put it in neutral and revved to 3000rpm. Tapping came on loud and proud and pressure dropped to 20-25 and idle dropped to 850 rpm. Ran like crap all the way home.

So, Like I said earlier. Could the crack in the (Front Bearing Cap) 1988 Raider Manual Sec 9-36 Part # 19

If this is cracked could it affect the oil pressure in the rocker arm assembly?

I cant find any documentation on oil flow? Does the Rocker assembly get it oil from the bottom side of this from head surface?

I plan on pulling cover and inspecting and cleaning rocker assembly tomorrow.

Thanks,
ShOOter
