Is it true that you dont see a gain of horsepower if you replace your carbs with FCRs, your quad just runs ALOT better, and has better throttle response and such??

 

Yes...all true...they made a huge difference...it even starts and idles better

 

well in drags i see a nice diffrence when i race bikes with FCR and then the ones with out them i dont really see a diffrence... With them on other bikes seem to be faster.. jmo

 

I raced a 690 with out the carbs and with the carbs and there was a big difference, like 5-6 bike lengths difference.

 

I love Mine. Would not go back to stock for nothing.

 

Gotta mention how easy it is to jet. I timed changing both main jets in 7 mins and 34 seconds with two breaks to hydrate with a cold one.[img]i/expressions/face-icon-small-wink.gif[/img]

 

Well we will just have to see about that, Just got my bike back today with new FCR 35's and it sounds and pulls SWEET!!!! Sam, when you going to Pismo???[img]i/expressions/face-icon-small-wink.gif[/img]

 

I haven't found the extra top end yet, probably my own fear of running too lean on the stock rod. I get a blubber *sometimes* at WFO, seems to happen when it's a hot day. Put a modified (EHS style) airbox lid on and it blubbered every time so I think I'm pretty close on the rich side. Plug looks decent now that I went one step colder and also richened up the mid range one groove, same dark tan (not brown) at idle, medium cruising, and wide open. I wish I could find a quad dyno with a gas analyzer near Washington DC, it would be nice to use something more precise than my a$$.

Do you FCR-smart guys think I can tune them on a dyno without a gas analyzer? There's one within 5 miles of my house. I don't know his experience with FCRs and mine is limited, should I spend the $100 or leave well-enough alone?

Anyhow, mine run 100X more reliable than the stock carbs and have instant throttle response. My quad pulls harder than the stock carbs clear through mid range and then not quite as screaming on top as 190/195 in a modified set of stock carbs. When I say screaming, I mean like V-Max kind of acceleration screaming, right up there with sex:-) Could it be that the quads racing on stock carbs haven't figured out all the fixes if the FCRs are running faster? Anyone dyno'd properly modified stock carbs against FCRs? As far as I know, Craycraft is the only one that's with a kit for the stock carbs and unless you know his secrets, you can't make them run at full potential.
