Rear end out of alignment?

I called Jeff at F.A.S.T. today and ordered some new parts for my cool head setup. He must have been at lunch or busy so I left a message. He returned my call promptly after, and took my order. Everything should be here early next week. What a pleasure to deal with. I wish everyone had customer service like this guy. Another satisfied F.A.S.T. customer here.

Well you said you turned the air screws in and it got better right? So that means you made it more rich and it liked it, so why did you go down two sizes on the pilot? Put your 32.5's back in it and adjust the needle down one slot and see how it works.

I ride with member KingBoo quiet a bit his father in-law has a Raptor 700. With boo riding the Raptor and me on my Shee, I mop the floor with his ass. The Raptor is an all stock 08 model and it is well broken in, my mods are in my sig.

Check your intake boots and make sure they didn't crack do to the boost bottle. That would cause a lean condition, which in turn may cause your popping and or hard starting problem.

LOL :yelrotflmao: Pretty much seems to be the general answer. Some believe them to increase bottom end if you put them on the jug side of the reed, and top end if you put them on the carb side. Its kind of like carb spacers for v8's every engine is different.

Whats a good tire to pair with the Ohtsu mr501 for the front.

I always pictured single carbs to be more of and all around setup. Great low-mid and slack off where the duals shine @ WOT.

Paul Turner MIDS!!! I think they are an awesome trail pipe. They park great mid range punch still retain somewhat a nice pull in the upper revs.

Here's a pic of the said tire . What do you guys think to heavy? Not soft enough?

Golden Spectro 50:1

Anyone ever ran the Carlisle AT101 Chevron's? I can get a good deal on a pair of the 21x11x10's and was wondering if they would be a good tire for hill shoots and dirt drags? They are 4ply and weigh about 16lbs each.

I am currently running the first gen razr's, I think they suck for the type of riding I do. They are pretty predictable in a slide but that's about it. We ride a lot of loose dirt power line type trails and all they do is spin. I'm looking at something a little more spaced out like the irazr's. or maybe some Kenda knarly's

Yea I'm 600ft above sea level. 19cc's will give me approximately how much compression? the engine is very fresh it 64.5 mm bore, stock stroke, wiseco prolite pistons

I'm located in Birmingham Alabama. It's a 64.5mm bore wiseco pro-lites, stock stroke. I want to bump the compression up high enough to make some good power and i don't mind having to run race gas in it. I was gonna buy a head from Jeff @ F.A.S.T they are made by Noss.

bump someone has got to know.

It seems to really do it from about 5%-15% throttle position. Also it got better when I went down a hole on the needle and turned the air screws in a half a turn. So now the clip is in the fourth hole and air screws are at one turn out. That's why I figured it was time for a larger pilot jet.

I'm getting ready to purchase a cool head for my ride. I'm intending on running leaded 111 in it. So I would like to know without welding the stock crank how small of a dome can I run? Ideally I would like to use 17's. But I have read that the cranks need to be welded b/c its a two piece design. I usually only really ride it twice a week for more that 30 minutes. Mostly on Sundays for a few hours at a time. How long do you all think the stock crank would survive that kinda compression?

I would say 27.5 pilots and 340 mains to start with. But I would wait for some of the more experienced guys to chime in. My estimates were made on the assumption that you will be running no air box. If you are running a modded box it'll be a few steps leaner.

Well whats the elevation in "south florida"?

I personally run Golden Spectro, premixed at 50:1. No problems thus far and believe you me she gets beat on hard.

I would talk to cpi when you order the pipe's. There's no need to put a filter and jets in it now, then re jet it when you get you in-frames. Do it all at once

Those were the exact steps I took. I still have a little throttle tip in burbble/hesitation do you think a little larger pilot jet(27.5-30.00) will take of that?

What do you guys think Lean/Rich or just right on the mains? The top pic is the left cylinder and the bottom is the right cylinder. Mods are in my sig. Elevation is 600 feet above sea level, Temp is 65 degrees and humidity is around 80%. Mains are 320's, pilots are 25 and the needles are on the 4th clip down.

Check the cold side for spark.
