Yamaha TRX850 Enthusiasts Forum

Been thinking and are a bit annoyed about the 4,5 - 5,5k rpm dip i have on the dyno.
Anyone checked when the squirt is coming on the FCR´s? I way back got a tip to cabletie it so the squirt is immediate and i think it actually was better. Now it´s lean going off and then rich in the above rpm.
A direct squirt should be better huh??

Oddly enough mine showed up with one around the 4500 mark too cause its annoying its right around 100/110 kmh in top with the 16/40 gearing.. A pain in the butt on the highway

Around 4600 to close to 4800 it actually looses maybe 2 or so h/p before climbing back up again.. It's a nice curve with this one hick-up in the middle

Looking mostly on my A/F and it goes rich at 5k...so i wonder if the squirt comes there now when i have it spring loaded....hmmm.

The FCR-MX carbs can sometimes be fitted with a Merge racing spring mod instead of using an O-ring or safety wiring them together http://www.crfsonly.com/catalog/product ... ts_id/4497

Cheers fer that!
