Well guys,Cam has been installed as well as new lifters. I am looking at putting it on the dyno at the local stealership. I am a bit concerned about the bike-it has 23,000 miles on her and is a 96 FXDWG (as you can see below!). You think a dyno is too hard on the bike? I like to ride relatively fast,but I dont like to hammer on my stuff. I would hate to damage something-advice?

 

Nope,

Shouldn't be a problem if the bike is mechanically sound. Did nine pulls on my 93 FXR after break in on a new 85" top end with a few other goodies. The cost for the Dyno session was under $300.00 including the jets and S&S carb gaskets. Be aware that the rear of the bike is loaded down and there is the possibility of shredding a belt, rear tire, or that a driveline part could break. It's rare, but it can happen and IMO this was the best money I've spent on the bike. It ran well before, but the difference after the Dyno session was like night and day.

Alot also depends upon the level of experience of the Dyno operator. Some guys just screw on the throttle and let the engine scream. My guy does all his pulls on the Dynojet from 0-100mph in 4th gear, he makes fairly short pulls, analyzes the data and then makes adjustments. We could have stopped at eight, but wanted to try a more aggressive advance curve. On pull nine, on curve #5 we lost 5 hp and went back to the less aggressive curve #4 selected on pull eight. At 10.5 to 1 compression I have no pinging using 93 octane Shell fuel and the VOES is still operational. She would up with 98.6HP and 95.3 ft lbs of torque, not bad for an old evil!

 

Don't worry- I had my '92 run after 85k miles and never had spun it higher than 4k rpms in it's whole life. Needed to get carb issues and ignition problems sorted and it was best way. I had spent $$ on cam, heads, pistons, carb, etc. and never knew what the bike could do. Ended up with ten runs done at varying speeds and redline runs- 85HP and 85 ft/lbs at 4500 rpm, so she pulls well for her age.
