Greetings, I have a 93 Honda Nighthawk 750, 14K miles, and was leaving school yesterday while they were repairing the parking lot. These guys, who none of them resembled engineers also made 2 speed bumps or breakers. The first one I went over, no problem. The second one I approached that did not have any access in center or at the curbs, was very high. I slowed down to a 'trials' pace and climbed up it what seemed to be a short width 9"-12" height. I touched the brakes at the top to keep from falling over, and heard a 'crunch'! When I looked at the pipes later, they were crunched well both sides (I weigh 270 lbs), and my acceleration seemed flat afterwards: it wouldn't wind out. Well this is $700 CA oem pipes if it is anything total. Does anyone have any suggestions or experiences about these situations? There were car scrape marks on them after a few hours when I left and I am the ONLY motorcyclist at our school! On Sunday's a Korean church uses our parking lot with about 150 each $30k-$40k nice 'low' new cars. This should be interesting for cheap makeshift speed bumps. However I do want to get at the head of the line for damages, for what good that will do. ** I really am afraid I'll build up backpressure running my pipes as they are and may ruin my engine with the exhaust not properly vented. My ground clearance is ONLY 5.5" and I haven't even got my center stand yet!!
