Great news, don't know how big you are but dropping down might lose some low end, but of course you'll gain on top..another thing they suggested was to change the shifter and use the one off the 125, I did it but then changer to a Hammerhead...Wink

Why the 125 shifter? What does it change?

My issue is the bike is SOOOO snappy in the mid range, and my throttle control SUCKS, I sometimes have a hard time working with it.
The 125 shifter has a different bend and bigger knob..as far as throttle control, just keep riding it, you'll figure it out brah...Wink

Also just break down and but a ebc 280 mm front rotor really changed the way i ride it. Charge the corners last second EASY on the front brake and maybe i dont go over the bars. Lol its that strong. Love the dcreased effort when im tired. Every now and then i forgwt and pull it regular and damn near go over the bars lol

The 48 rear has felt good at most tracks, tried a 49, but if the track is not tight, you seem to have to shift in the middle of turns

I do alot of hillclimbing. 49 really helps 4th and 5th pull much better. I cant really notice any diff. 1st thru 3rd with one tooth change. I always used to go up a whole tooth on the countershaft on.other bikes ive had but i wouldnt ever try that with this bike. My kx250 loved a 14 countershaft i just kept it in second and third a lil longer and the 10 extra mph at top was a blast.

Im retarded i mean add a hammerhead tip to the stock rear brake. If u get a tip in hand its not too hard. Love the big pad.much better feel without paying for the whole brake lever. If they even make one that fits idk. I just bought the tip to their lever and whacked off the end of mine and added it on. Wound up 10 mm longer and looks pretty trick.

So I rode the 4 stroke on wednesday, and felt the best speed wise I've ever felt. Got the suspension back for the CR250 that night, and got it put on the bike. I also messed around with the carb fitment, and couldn't make it better. With the subframe off, I had an exhaust leak from the pipe to the silencer. I didn't use any ultra copper on that connection, and paid the price. So I put a brand new rubber and some ultra copper on and she sealed up great.

Rode the bike last night, and it was a rocket ship to me compared to my 250F on wednesday. Bike was running fine I though, but kept smelling something burning. Got back to the pits, and the silencer was smoking. I checked the air screw, and it wasn't right, around 2.5 turns out, so I moved it back to 1.75 out. Worried the bike was lean and melting the packing in the silencer. After I richened the bike up, FGR had me lean the needle, and damn the bike woke up more. No more weird smoking, bike ran great, and pulled damn hard.

I really need to work on getting faster on the 2 stroke, right now I would SMOKE myself on my 250F. Going to ride the cr250 for the rest of the summer, and let the 4 stroke sit awhile.

lol!!! And she just asked.. "Why do you have two bikes?" My reply, "because I haven't figured out what I want for a third bike"

She laughed.

Just dug out a nearly new 49t sprocket to put on. Hoping this mellows the bike out some.

I'm having some issue with braking power, it doesn't feel much better than my CRF. Going to put the CRF caliper I have on, and bleed it with the mityvac I just bought.

Yes. I'm thinking the '04 caliper is in the same shape the rest of the bike was in, not good. I have an '07 caliper that came with the 07 CRF master cylinder. I am going to put that on and see if it's better.

Ok so I bolted on the air Stryker carb with the jetting set up by JD and it came with a 175 main but it was (seemed) too rich, so I dropped to a 170 and it still won't clear out at full throttle. I have a 2002 with a pro circuit pipe and v force reeds. Do I go lower on the main?

Try it. You're not going to hurt it with a couple of wfo runs down a short straightaway.

You might try to raise the needle clip too (drop the needle down), mine is always rich and it seems like I'd be stepping too lean but it seems to run much crisper. Lately I've been running a 178 at the sand dunes for extra safety but I honestly think it's too much. Just keep dropping down until you ping or get a white-ish plug then go back up a step.

You have to drill and I did such a terrible job yet it somehow came out straight as an arrow.

Thanks will do. I thought going to the 170 would be sufficient but it still wouldn't pull cleanly after an extended warm up. I think I will go with the clip first but my intuition tells me it is still a little rich on the main. Has anyone gone to a 165 on these things?

What is your elevation? Is your right crank seal working?

The entire bike was rebuilt top to bottom with only a little over 3 hours on it. I am about 700 feet above sea level and I sent all the info (pipe, reeds) to JD when I ordered the carb from them. It ran well early in the year (May) when it was cooler out but since then it just won't rev through past 1/4 throttle. I checked the plug before I went to the 170 and the plug did indicate it was rich.

Everything I researched told me to get the airstryker-plug and play!

Just goes to show you can't believe everything on the internet. Not that other guys haven't had success with the air Stryker, but I'm kinda in the same boat as you. Similar elevation but it just always feel rich and wants to load up and not reving out cleanly. I had it running like a top fuel dragster ONCE. Not sure how I can go back to that setting and have such a different feel.

I'd check your power valve operation. I adjusted mine yesterday, I've read that can have a huge effect when you think it's right but it's actually not.

Yes I was thinking that I would check that, thanks. I'm going to lean out the needle one position and look at the power valve while I am at it.
