i know i love my carbs..... but would i notice any difference going from fcr35's to fcr39's?

 

Bad350- If you think you could feed your motor more carb than you have now, go for it. I would not have thought they would have worked. Ernie660 put them on for a different reason. He was planning on turning his 686 into a 730 this winter and just wanted to do some R&D for Craycraft since he was down here for the weekend. He jetted them like he planned to run them in a 730 (160 mains) and his 686 loved them. HE HAS FORGOTTEN ABOUT THE 730 AND WEB 685 CAM FOR NOW. He is going to run this set-up for a while. It is sweet. I do not want to line up beside him anymore.

 

14- she sounds like she runs good......in fact i think all the craycraft bikes seem to run good! i dont think i would switch now unless i decided to go BIG bore! right now im happy with it. To bad theres not a good group of rappy riders like you guys around here! hopefully some of the guys around my area and jump on the bandwagon..... all i get to race is alky banshees and Zombie..... and i havent seen or heard from him in a while!

 

Can you buy these intake manifolds right now from Craycraft? How much are they?


Thanks

 

Sand rappy- Give Bob a call, i am sure he will hook you up. The intake set-up like ernie's is around 225 dollars. I know it is a little pricey but it works. Bob spent weeks working on it and the suppliers are greedy. Bob is also working on a few other intake options that are going in the "testing" phase in the next couple of weeks. Going fast cost money. There are 2 craycraft project bikes in construction know that are larger that a 727. This is a big step foreward to making big power.

 

Im saving my lunch money for a Craycraft big bore special, Hopefully before the big drags.

 

That will be a sight to see when Mario is on Raptor. I have a few seconds of a video with the Sandpig climbing on my stock (basicaly) Raptor and then the next weekend the Punisher rode that same quad up the hill a couple times. Classic. LOL

 

he congrats Ernie! Hopfully one day ill be able to compete with all the big dogs [img]i/expressions/face-icon-small-happy.gif[/img]

Yeah, I have been getting details on what to do between Feb. and March with my Raptor.

I think maybe a 686 is on the way.

 

I just got home after a long six hour drive from Bob Craycraft house and I had to ride the rappy around the neighborhood. I am still in shock of how fast that 686 is.

I have never ridden a 730 as of yet, but if its faster than what it is know WOW! I am sure there are plenty of faster quads out there, not bashing anyone!

The reason I went with the 39mm fcr's is because of the fact that in the future a 730 is in the works. I had no idea how my 686 was going to respond to the 39's but I had to try in the name of research and development. Its a winning combination if you ask me, the signature series Craycraft 686, stage two Hot Cams, 39mm FCR's, 12.1 piston, is a choice that everyone can live with and most important leave you grinning from ear to ear for a long time. I,m still grinning!!!
