Hows the cooling of the stock Scrambler rad holding up for that sled motor?

 

The cooling has been good, only time there's an issue is slow trail riding with the fan turned off, that said I just hot wired the fan to a toggle, but for a temp switch if I wanted, I would just pickup a universal automotive temp. Switch (would have to figure out a temp for the fan to turn on though, easy to do with a temp gun), wire it to the ignition hot and the fan and presto, good to go.

 

had to do a carb switch, old ones had some issues when i started to get into them to swap jets (2 of the three pilots were stripped, one choke cable was fubar'd) i got lucky and found a set off an 800xcr, so the jetting is going to be dang close to what i'll need too:

 

So got it running with the new carbs, started great, but then towards the end of the day i went to start it again and i found that one of the carbs is leaking fuel, so odds are its a stuck float, fawkkkkkk, they were a pita to put in place, and its not something i want to pull back out again, anyone have any tricks to get to the floats on these flat side carbs (no screws on the bottoms to unscrew the bottoms)?

 

So got the float unstuck i hope, used a little trick with some food colouring, deagrease and a bit of compressed air, so onward with the tuning, hopefully i can make a few runs tomorrow .

 

Loaded and ready to go

I have some tuning issues to work, if you listen you can hear the motor top out really early (just over 1/2 throttle), outside of that everything is working good

 

Almost got the tuning/jetting isseus sorted out, also pulled the secondary off and tossed in a blue/orange spring in, clean the primary up, yanked off the oil pump on the motor and made a block off plate to seal up the hole, pulled all the scrambler wiring off, rewired the machine as per the ultra wiring diagram minus the accesory wiring, still need to get a voltage regulator to get the battery charged up, i'm hopingi can get it running good tonight, as we should finally be able to get harvest wrapped up on the farm giving me some time to work on this machine.

 

Sounds good let errr rip.Is that a sled puller only bike or do you run it as an all rounder?

 

all rounder, built it cause i wanted a can amm renegade, but didn't want to drop the coin on a new one, so i decided to build something that'd eat it for dinner and poo out 700 raptors . . . .
