I am sure some of you have put FCR carbs on your 04-05 trx450r's
I put one on mine over the hollidays and cant seem to get it running correctly
idles a little rough, pops in the midrange
here is waht I have :
05 trx450r, full LRD exhaust, white bros rev box, K&N filter no airbox lid, titanium valves, HRC cam, motor is fresh 30hrs or so since full rebuild (running at sea level)
old carb set up :
stock 05 carb, HRC needle 6th clip,50 pilot,190 main,air screw 1.75 turns out.
ran good
New carb setup:
04 CRF FCR carb,all nessary adaptors to mount, boyson quick shot,GFP needle (LRD's needle),162 main,45 pilot,air screw 1.75 turns out
the TPS on the FCR has a block off plate (I thought this may be a proublem but the edelbrock carbs dont run a TPS and the instructions say to tape the harness plug off)
any tips or ideas ?
