By the way just to clear things up Does anyone have the Photos from Matt Smileys predator in dirtweels back in 2005 or 2006. There was a side view of it and if you look close you can see the frc ac pump. Ill have to see if I still have that in my garage. also I think it was OUTLAW50(mark ) who talked with Matt and he comfirmed Smiley had the fcr on it PUT ON BY POLARIS's race team techs. JUST SAYING !!!!  that was a stock engine or at least stock bore and cc size.

Not to pick on any one person, but I sorta laugh whenever I read that this racer or that racer ran this or that "part" so it must be the best thing in the world and everyone needs to have it now, .....  to be any good!

 

The thinking is that your "average joe Racer" just has to have those exact same parts to be able to have their bikes be as good as the racer they are trying to copy.

 

I highly doubt that there is much "stock" anything in most racers motors besides the mandated bore and stroke dimensions. And sometimes the builders even fudge on that, if they can get away with it...............

 

 

 

 

 

 

Back on the topic of the FCR carb. I have not said that they are not a good or even a great carb.

 

What I do question is if they are worth the cost of upgrade, for your average Predator trail rider, for the real world improvement they 'might' bring to the mix.

 

 

They are expensive. Average used cost is $300 bucks. New / retail ( not E-bay )  they run approx $600 - $1200 bucks depending on who is selling it and what 'mods' it might have done to it from the retailer.

 

They are hard to fit.

 

You have to cut the seat pan to clear the carb fully.

 

You need a custom spacer that is hard to find & hard to fit. (get sealed up)

 

You need to come up with a custom throttle cable or mod the one you have.

 

They have a much harder spring (throttle) pull even if you run one of the Tokyo mods springs.

 

And for your effort's you might ( might I say!! )  see a H.P. or two or a few lb feet of torque increase, maybe!

 

 

Personally I would suggest a good suspension upgrade for that cost. Way better return for your money and a guarantee that you will be faster with a good working suspension than you will be with just a carb swap.

thats all true bob.  However those racers have full time machanics who are paid to know there sh!t.(better then us believe it or not) do you think for one minute that a factory race team machanic is just slap on parts guy because everyone eles has those carbs/parts. Those pro racers test the hell out of there parts/quads more then any of us.they don't just toss on parts without testing them and hope for the best. IM TALKING PRO CLASS not c class. I'll agree the average joe racer is a toss on guy but not the pros.

I do agree with you that the average predator build does not need a fcr and that the money would be spent better on good shocks.

i totally agree suspension is a much better go fast mod.

if you get the polaris outlaw fcr you will not need to mod your thumb throttle at all and the stock polaris outlaw cable fits right up with no mods. also they can be had on ebay all day for about $200 i have sold 2 this year for under $200 and lenick just sold his for $200. i know $200 will go further elsewhere. i have spent $200 on 2 horsepower many, many times on the predator so i agree it is not the best investment but i have also spent $200 to $500 to lose 2 hp on the predator many times. i can say without reservation it is a better investment that many of the "performance" mods i have thrown money at.

Well got the fcr on and done. Modified my stock cable, built my own aluminum spacer and fixed up the intake to work with it, runs good and best money I've spent on it so far!!!

Will try and get my kids to. When I cut the aluminum spacer I cut it at 5degthe one way and also about 1.5 deg to the side. It angles it down and to the left. It gave me a lil extra room on throttle cable and world great as my cable goes right over the top of the frame cross member. After reading other peoples conversions I would say mine went pretty good and haven't even had to change main get. Put a 50 pilot and got rid of bog. Put a ziptie on for o ring mod as I've read when some are doing that but it makes the throttle stick. The main was a 175 and haven changed it. It runs good no dead spots and great power through all gears. I plugged the leak jet and adjusted the duration to get a good 1sec or so squirt! It even sounds so much better, my kids were riding it tonight and I noticed it sounds crisper and has a deeper tone. Man I ready for the sand dunes as the 250r gotand diald in tonight as well and is a monster. I will try and get pics of my swap and bikes posted!

I got to ask this just because Im a wise ass. Would you ever go back to the stock/ BSR carb again ? Do you think the fcr is a better card now that you did it?

Im glad you got it figured out, and your jetting sounds spot on. My 560 has a 185 and a 42 pilot.but thats a different fcr then the one your running.

Whats up with the link? I made the last post to that link. I know for fact he had a fcr on his predator. There was a write up in dirtwheels back then . In the side shot photo you can see the ac pump of the fcr. I can not seem to find the photo online and I do not think i saved the issue of dirtwheels. I also think steph ran the fcr also.

fcr dont need the tps attached on the pred........ your tps on the pred is in your throttle........... lectrons are kind of a pain in the butt but also do well once configured.........
