OK, no one has broken anything or is building anything; nothing posted lately has caught my attention. So I t thought I would share my latest motor work.
I have been collecting parts for a while now and finally have everything I need to upgrade my current 95" motor which is a garden variety configuration with typical 104TQ/96HP numbers. SE pistons and cylinders, TW44G cams, Woods Directional lifters, BigBoyz "street" ported heads set for 9.8 static, stock throttle body, Zippers Mo Flo air filter and Bassani Pro Street exhaust. Got the bug for more power but, JMHO, anything much larger than 98" in a softail with the balancer assembly just won't have the longevity as a smaller displacement motor and this will be the last motor work for this bike.
Anyway, new build configuration is 98", CP forged 6cc domed pistons, Don Dorfman's Pro Street ported heads setup for 10.7 static, Crane 296-2G cams with .620" lift, S&S roller rockers and Kuryakyn 57mm throttle body, a straight forward top end rebuild, right.
Well, to my dismay, when I opened the cam chest and checked crank run out, I discovered that it had grown from .0025" when I build the 95" motor 25K miles ago to .0045" now; not part of the plan. So, the cost of the 98" build has just doubled. The crank has to go to Hoban Brothers for service and T/B/W, cam plate and pump were both scored so they will be replaced with the S&S TC3 plate and pump combination.
The crank must have shifted recently as the motor has shown no signs of damage and no degrading of the performance. Perhaps my timing was spot on and saved me from a catastrophic failure on a lesser traveled two land black top in the Texas hill country; who knows.
I just thought I would let the forum know that even when you are anal and meticulous about building and maintaining a performance motor, bad things can happen; it comes with the territory. If anyone is interested, I will provide updates as I move forward with the build.
