Redbull500's Gen. 2 Cr500 with 86 engine

Redbull500 · Post by **Redbull500** » August 18th, 2012, 1:09 pm

Hey guys most of the way through this build already, built using a 2001 cr250r frame and a 1986 cr500r engine. Picked up the 500 cause the previous owner could not start it, cleaned out the carb, fresh gas, right up. The cr250 frame i got cheap due to a blown engine. Pics coming soon[/img]

Is this the guy you bought the motor from

It's pretty important to kick it through the next TDC, looks like this guy never did

No lol thats a huge fail, if he has that much trouble trying to start it I think his calling is on an 85 not a 500

All of it mate. We love these build threads ! I am about to do a Gen 2 to go with my Gen 4, and am very interested in the differences in the build etc. (actually contemplating slipping a KTM 380 2T into it, if I can't find another 500 engine at the right price . . . )

cylinder was messed with a bit

cdi location... its tight

bottom engine mount

front mounts was the only welding needed

its pretty ugly riging right now, but it works, going to work on better routing of everything this winter

kicker hitting pipe issue

coil mounted to back brake resevoir holder for now

spacer used under the front of the gas tank to prevent having to push in the bottom of the tank

The beer behind the bike

rear sunstar steel sprocket 49, pro taper gold mx PT520mx chain, new scorpion MX extrax 120/90-19 back tire

Do your radiator shrouds still bolt up at the bottom?

Redbull500 · Post by **Redbull500** » September 28th, 2012, 10:56 am

Ya perfectly still somehow

hoofarted · Post by **hoofarted** » September 28th, 2012, 11:04 am

you used a 250 pipe? Did it fit in the cylinder? And you need the newer style kicker too.

Redbull500 · Post by **Redbull500** » September 28th, 2012, 11:16 am

here is the keihin pwk 39.5mm carb

ya... it was what came with the 250 and at the time I didnt have the money for a proper 500 one, which in the frame one should work best? lol had to do a little cutting and welding of the flanges

what year kicker will fit?

also dropped the clip one and now it smokes a lot off idle, put it back to third from the top?

Kuma · Post by **Kuma** » September 29th, 2012, 1:42 am

'89 up for the kicker

jar944 · Post by **jar944** » September 29th, 2012, 6:38 am

what year kicker is that?

Redbull500 · Post by **Redbull500** » September 29th, 2012, 10:13 am

I think its the original 86 one

Redbull500 · Post by **Redbull500** » September 29th, 2012, 3:52 pm

Ordered the new style kicker today, new clutch cable, and shift lever as well

asteroid500 · Post by **asteroid500** » September 30th, 2012, 12:04 am

i wonder if the 250 chamber will work on the 500 motor .... there all built around the pulse rate of each motor arnt they .... not shiting on your parade just asking mate, im interested actually to see how it will work for ya

Redbull500 · Post by **Redbull500** » September 30th, 2012, 11:26 am

Its no parade lol I want the 500 one, going to order the 500 one soon, my bike smokes quite a bit right now and when i twist the throttle it takes a little bit of time for the revs to drop back down again? Any ideas on what is wrong?

Redbull500 · Post by **Redbull500** » October 2nd, 2012, 6:17 pm

new 250 clutch cable, feels ten times better than the old 500 one did

2001 cr250 msr shifter, fits perfectly

new oem 2001 cr500 kickstart assembly, no more slop, looks a lot better imo, also clears the pipe, ordered the procircuit pipe and silencer as well should be here for the weekend

Redbull500 · Post by **Redbull500** » October 17th, 2012, 9:24 pm

So got the procircuit pipe mounted, also installed the new v force 3 reeds with the moose racing torque spacer and a new air boot, have the 98 airbox boot to install as well as to reroute the cooling hose around the new pipe, ill post up some pics tomorrow night to show the new progress

I used the 2001 stock airbox and boot and it worked for me.

your motor has a 1987+ rod in it, hence the deck spacer

Redbull500 · Post by **Redbull500** » March 22nd, 2013, 3:28 pm

Hey guys, Canadian winter finally let up enough to work on the bike again. I am at the final fitment and jetting stage but need some advice. I am having a lot of trouble getting the airboot to fit properly without it ripping out the front air boot. I could not get it to work at all with the 2001 airbox/boot so I am trying the newer gen 3 ones and this is how it fits. Is it good like that or do I just go to a pod filter with a pre filter over it.
