Has anyone else had problems changing the '84 Honda CB700SC Nighthawk 'S' oil filter? I have the shop manual, and the special oil filter wrench that it recommends, but there doesn't seem to be enough clearance between the exhaust head pipes and the engine case to remove the filter, no matter what the shop manual says. I tried removing the small heat shield that protects one of the oil cooler lines, but that didn't clear enough room. In desperation, I pulled the whole exhaust system, but that's enough work that it sort of negates the whole point of the spinoff oil filter. Alternatively, has anyone had any luck with aftermarket exhaust systems? I've been looking at Vance & Hines and Kerker. Naturally I what it all: lighter, some more power, not much louder, easy (EASY) access to oil filter and drain, center stand retention, and no rejetting. Comments? Since my reception of net.cycle is tenuous, I would appreciate replies by email.

[] I too have an '84 Nighthawk S. Removing the oil filter with the exhaust system in place is kind of tricky. The filter should fit through the opening formed by the right-most (sitting on the bike) header pipe and the frame down-tube. It will be a very tight fit and is a two-step maneuver. First you have to get the fluted end of the filter into this opening. I can't describe how I do this, so just try different positions until you get it. Once the filter is in the opening it will slide easily until the rim (end of filter opposite fluted end) hits the header pipe and frame tube. By now oil will be all over the place, so a firm pull will bring the filter past this last barrier without scratching either tube. But if you're concerned, you can grease these surfaces it before hand. John Swanson AT&T ISL Denver

Thanks! > >John Sloan CSNET: jsloan@WRIGHT.EDU I read a report in a cycle mag awhile back that compared about 15 aftermarket pipe with the stockers on a gs1100 Suzuki. ONE pipe made more HP than stock, after properly jetted using a dyno, and the gain was like 2-3%. Several others approached the stock HP, within 5%, but the gain in performance was attributed to a weight savings of 15-25 pounds rather than plain HP. To get a real gain you need much larger jets, and very good earplugs. I would suggest saving your money unless you want to customize your machine for looks, and take whatever performance you get, OR, get a GSR1150!! cheers, dave
