So I love my little 07 250. I have the forks rebuilt with 10 w oil. I will probably replace the forks and front wheel. I want ex500 front end to rebuild and a front 17 inch wheel. I will also change out the front caliper. How much of a weight difference is there? I have a ninja 600 fat boy shock coming. I have installed a full Muzzy exhaust. I rejetted the carbs to a 110 main, 3 washers under the needle, and 4 turns out on the air fuel screws. She runs good at 6000 foot elevation. There is also the stock air box with a uni filter. I also put in irridium plugs. I might keep the back swing arm and just order 130 x 16 front tire and mount on back.

She is such a fun bike to throw around. I did have some over heating issues. I lost a bolt that holds the line out of the water pump. She shot all the coolant out while I was about 70mph in a corner. She got hot enough where the thermastat and fan switch have failed. Replaced and fixed she runs great. I have also gone thru the valves and all. The rear wheel removal is the worst design I have ever seen.



Them flames add 3 hp. ;P

hummm, my son rides the exact same machine... Is your gas cap getting "sticky" when you try and open it?



with proper waxing and detailing, you can get a full 4 horse power out of those flames.

110 with stock box at 6k', sounds like that would be pretty far on the rich side no?

I don't have a pre gen but I'm running new gen, with pod filter, + full race exhaust and currently have 110 main at 1000-2500' elevation and I am considering going down to a 108

IDK though? Just struck me as odd, u might have some room for tuning there

The EX500 forks are nothing special. They're pretty similar to the NewGen forks (they use the same spring and emulator part numbers). One or the other might be a little easier to swap in, but I don't really have any details. The front fender is a little more basic and slimmer on the 500, if you're taking looks into consideration.

The NewGen swingarm should bolt right into the PreGen frame (the 500's is a bit wider at the pivot), if you want to go 17" back there too. Once again, I'm not sure about the wheel/brake details, but the swingarm itself should be pretty PnP.

I bought 107.5, 110, 112 mains. I started with the 110 main. She runs great with no flat spots or bogging. I am happy where she is at. With out some dyno time I am afraid to go too lean. My local shop said they would hook her up and sniff her after work. I may take them up on it.

I got the zx600 shock today. I emptied the old oil and added bel ray 7 w fork oil. I put 15 lbs of air pressure back in her. Boy does she feel better. The loose pogo stick action is gone. She is much tighter.

No sticky gas cap but I have lots of fun on her.
