stock was 58hp

only way to know what you have is to pony up and hit the dyno!!

i remember an article in a dirtbike magazine a couple years ago and it had a dyno from a cr500. it put out 63 at the rear wheel stock. so i'm gonna guess that you've added at least 3-5 hp with the mods you've got. :eek2: So you should have mid 60's at least...

Sorry i didn't see that you had porting done too.. guess i should read better.. What type of portjob did you have done? Heck your power is more than likely in the 70's if the porting is decent at all...

got it out for another run today and dint blow it up this time. was breaking the motor in and at 1/4 it was pulling away from a 450r. the porting looks prety dam good ( no i dunno what im looking for). its damn shiny and theres not much metal left between the two ports on the exaust and around the ones on the intake. the prvious owner also had it in a 400ex and draged at the dunes.

my jettings prety f'ed right now. bogs and dies if i go past 1/4 throtel. i think im gona have to find a dyno to get it tuned and get some numbers.

if anyone knows where any quad dynos are in ontario, ny, or quebec that would be great to know.

when i had my cr 500 it was set up for ice racing. the guy had tons of work done to it and said it was in the 70's hp. these motors are tq monsters so dont get dissapointed in the lower hp numbers if your only in the 60's, its the tq that matters. used to be a site called larryscr500 page. also do some searching for cr forums and cr500 forums, also swap in the words message boards instead of forums and you should get some goood places to get your info.

i did some calling around and found a bran new dyno about 25 min away. il have to wait till its up and runing because there exaust ducts arnt installed yet. il prolly do a few runs on it in a couple of weeks. and best of all itl be cheap cuz im gona be the first one on it.

I have been told that this should be about 63 HP stock.what do you think it is with the intake carb and custom exaust I made for it?Mine is under the other catagory in sport quads over 300cc's section.
