I had to brag, I just purchased 41mm for my bike. Can't wait to get em & put them on. ;D If they show up by the weekend then i should be able get her back on her feet by Monday, hopefully the Sun pops back out. The only thing is I still need to fabricate some custom exhuast tips as I sold my arrows over the winter. I can deal with it being load as Sh*t. [evil]

They're good stuff. Just got a set installed on my bike a few weeks ago. Took some serious fiddling in the way of main jet changes and needle clip position to get it to run right, but as soon as it ran right, it was abrupt. Like it never knew it ran wrong.

Various people have various reasons for their hard-ons after installing, it seems. My favorite is how it just smoothed everything out. Enging braking is a lot less violent, and revs are at a flatter constant rather than the V-twin extreme. It's like taking 45 degrees out of the cylinder spread.

I don't hear the whooshing noise advertised with pod filters, but my bike is loud as sin and I have hearing problems. Can't manage the power wheelies by accident, but I'm 215 pounds.

It's hard for me to say what actually did what, as well, since I installed ExactFit coils at the same time. And belts, plugs, oil change, chain tightening, new clutch slave, new-to-me cluster, guh.

Really, the best part is the fun size Snickers bar that Chris sealed individually along with a decal.

When I installed mine I changed everything else on the bike short of wheels and engine too, so hard to say what exactly the FCR's did.  The sound of them sucking in air when I whack the throttle open is very noticeable to me, along with a little mechanical rattling most of the time.  I had my bike down for so long with mods that it is hard to say if it is noticeably quicker, because I don't recall exactly what it was like before.  Mine bolted right up, didn't have to mess with the jetting.
No power wheelies for me in any gear, which I'm a little disappointed with as that was 'advertised.'  I weigh 160.

2nd gear power wheelies for me. Nasty ones. [evil] 3rd gear wheelies up the mountain pass pinning it from 4500 rpm.

Motor has JE hi comp pistons, Kelley coils, open A/B, dialled cams, Termis, light flywheel, light clutch, inlet porting and valve job. The FCRs made the mods work together while the CV carbs were never quite right and held back the engine mod combination from fulfilling it's potential.

FCRs tied the package together, give better mileage and work at zero degrees C.

So any suggestions on how I might achieve said wheelie?  Technique or anything... in reading the reviews on the CA Cycleworks page it didn't mention that any other work would have been needed in order to get those power wheelies in 2nd gear.  I'm relatively light, running the open airbox, etc.  When I shift to second and open the throttle all the way, it definitely takes up all the travel on the forks, but the wheel doesn't lift off the ground....

The forks should compress a good bit after you chop the throttle and before you crack open the throttle.

Well I only have a 750 so I'm not expecting to be able to Power Wheelie even with the FCR's, I"ll definitly be trying. I'm really hoping to get a overall better throttle response. I havn't rode since last year but Since I got the bike I could open the throttle all the way and it would just lag off the get go. I know it's carbs and not FI but what i have heard is it should be a night and day difference with the FCR's and the Mikuni's for throttle response.

This will be the biggest change to the bike other then exhaust, I did go with the pod kit which I was already running on the mikuni's. I haven't heard anything bad about them and this will/Should get me by until I can afford to have flywheel and engine work performed in the future..


I will be calling Chris if I don't get that snickers bar ;D

I thought the 39mm FCR's were recommended over the 41's for the 750, no?

Joshua

Talking to Chris he said I wouldn't be able to tell the difference on a 750 between teh 39s and 41s.  figuring they will leave room to grow if I go more indepth  with engine work and I can always re-jet the 41s if they seem to be to much for the 750. I don't want to limit myself to the 39s, But you are correct 39s are recommended for the 750. I have bigger dreams for her then just exhuast and carb work in the future.

It may be running with the out-of-the-box jetting, but if it's down on power, sounds like jets may be in order.  Carbs are more sensitive to the specific setup of your motor... even minor changes can require rejetting.  The kit builder/manufacturer provides "vanilla" jets that'll function, but to really dial it in you need to find the correct jetting for your motor as its currently configured... A/F ratio should be close to 14.7 all through the rev range (maybe a tad richer when accelerating) to maximize power.  Get thineself a Colortune or have a shop dyno it with an exhaust gas analyzer... then you'll know for sure whether it's too rich or too lean.

Colortune is available here, or here, or here... I ordered mine from that last link, and I ordered the kit that included the 12mm and 10mm adaptors.  Wound up being around $58 USD shipped at the then-current exchange rate.

ColorTunes are cool.  Nothing quite as cool as watching the flame front in your engine.

Yep.  :)  I was totally geekin' out when I got mine in the mail... went out and used it to diagnose a faulty fuel injector on the VW within an hour of opening the package.

Blue flames are cool.  [thumbsup]

I say it beats the gas tester for pure fun and entertainment while doing the same job.

The intake pulse is audible, but I have a hard time describing it as the colloquial 'sucking', and even less how other scores of folk have deemed it, a 'whoosh' or a 'honk' (???) -- doesn't fit the definition of either, in my opinion. And it's generally only noticeable when I'm rolling on in too high of a gear. The chirp does seriously indeed stand out, though.

I'm a tad rich with my mains where they're at. The stock 155s had to come out for 170s. Yeah. And I went down two notches on the needle clips. I guess V heads and circa '99 DP straight-through cans really make for good breathing.

I've had great luck with easier starting, as well, now that I think about it. I guess the Mikunis were the prime source of cold blood. It's kind of absurd just how many benefits the FCRs offer. The world doesn't usually give so lavishly without taking somewhere, granted they're an expensive hangon, but we've all dropped more greenbacks on worse.

Also,

Yeah! In your face, non-believers!

Well in anticipation of my carbs showing up, I decided to clean the bike and get the old carbs taken off. i went a little over board and took the whole damn thing apart.

Much easier then I thought, i started with the wire harness, that took longer then anything else and everything else came apart very easily. everything #'ed & bagged accordingly of course. I've always wanted to powder coat the frame and i figured with 17000 miles on her replacing the bearing would be a good Idea for everything. So know I get to call daric at Cheshire and see if he can order me swing arm, steering, shock  bearings with a quick turn around, i can only hope.

Now I've decided to go with a gold powdercoat to somewhat match the brembo calipers, Shock will be the same color and so will the forks. Swing arm will be powdered red along with the headlight & mounts. triples, rearsets & intake tubes powdering black, I would like to possible powder the heads but I want to get back on the road sometime this year and even though I'm confident on tearing the bike apart and adjusting the valves I'm scared to remove the head and all the componets for powder to be done.

Anyways i might need to change this to a build thread rather then a thread about FCR"S. Wish me luck and if any of you have photoshop and would be willing to render a picture with my description that would be sweet. ;)
