[QUOTE="AJ Waggoner, post: 1074362, member: 16665"] Chris- I've never dyno'ed the project bike, but with that port job , and the new stator/rotor /CDI assembly the AFX uses, certainly torque/hp is increased over stock. not by heaps and goobs, but a decent increase in the *right* places for trail use low to mid .(its an AFX and intended for that) It diffinantly runs noticibly crisper and cleaner in the low end (digital CDI vs older analog OEM CDI )and if you read the article ,and sidebars,JL states how it seems like a diesel tractor,,and Jesse talks about it being "4 stroke like" The whole design of that system and Erics porting was for a torque usable spread of power.. this wasnt to "detune" the 500, it was to spread out the power, and increase traction. On a dyno it will have both an increase in hp, and an increase in the torque curve..but the IMPORTANT part would be where those increases where in the rpm curve! Shear numbers mean very little as you noted in the CR250 vs CRF450 charts. Its why you dont see mag tests do them all that often.It is just as "subjective" as saying anything else? If they say "pulls like a diesel tractor" ,or "more like a 4 stroke" most people can relate better than trying to decipher a torque curve vs RPM placement on a dyno chart? i'll give you my ride impression,and i have a decade or two on CR500's :) This setup is very low end andmid range oriented, it pulls harder than stock, but over a broader range so seems much smoother..the reality is it is pulling just as hard (on the dyno) but that stock mid range arm ripping "hook" is broadened so it doesnt give the rider that sensation. It just starts pulling much earlier and pulls on thru a bit further. It isnt meant to be a hp king, or scare you with its big hit. So its not the setup i would build for every CR500 customer. It was built to keep all that power hooked up to the ground and have very torquey controllable output.Like the old Maico 500 engines ;) One thing i think effected the DR testers impressions were the WR gears. They are the same as OEM at first and second, but are wider ratios third fouth and fifth. As delivered the bike was geared(sprockets) to tall(stock) for the WR gearing(internal). This would also make the bike appear more *mellow* third gear and up.(where you likely want it to then "open up" and HIT a bit!! ) I did not really care for it..and had zero experience in setting up a bike with those gears.. after some testing and speaking with other CR500 riders that have ridden with the WR gear setups ..I now know, what overall gearing(sprockets) would be best. It wasnt that bad, but could have been set up better for that internal gear set. Did i mention 30 days stinks to build and test a bike in? Especially when I/we get those WR gears about 35 hours before the bike needs to ship? lol That bike was built from the frame up ,in that time frame. Not a diclaimer and not whining! LOL! ..just showing how little time there was for any shake outs of the details or setup. I was completely stoked with the bikes final performance,especially in light of how little time we had to build it and dial it in. ( in a more normal situation i would have tested and dialed it in, for at least a couple of weeks before handing it off for a magazine review) [/QUOTE]
