to quote someone with a good turn of phrase , " The DR bottom end is as reliable as an ANVIL "
I reckon with a larger oil cooler ( like the newer DR ) , high compression ( 10.2 - 10.5 : 1 ) , a big bore , expanding link pipe exhaust , open airbox , pumper , and a bit of head flowing and exhaust header cleverness , you could wake that beast within BIG time.
The great thing about these oldtimers is if yer gonna look for a sacrificial Lamb , you are working off a budget platform , but a model with plentiful spares and spares bikes with which to stock your garage ...
My DR with 30 000 miles on the crank , abuse and neglect , had ZERO and I mean ZERO big-end play when the top end was off.
When you look at the strength of those components you wonder how far you could push it !
I recall the old misty days of the GS750 , you could put a blower on that bottom end and go to 150 bhp with a bone stock mill , if you did that to a Kawa it would fold like tin foil.
Old Suzooks are TOUGH. 100mm bore ... YEAH !!!
