250 trail blazer mods
#2
I'll see if I can help get the ball rolling for you. I recently picked up a used '05 Trail blazer. I liked the machine right from the get-go, but I wanted to get rid of the lazy acceleration when taking off from a standing start. After doing some on-line research, I called Ritter Racing and told him what I wanted to do. His fix was to get a heavier primary spring - a black/white stripe - to install in the drive clutch. When I installed the spring I also changed the main jet in the carb from a 130 to a 125, dropped the needle one notch in the slide, and adjusted the air screw to make it idle better. Just these minor changes made the quad much more responsive on take-off, and only cost me about $40.00. I'd guess the spring raised the clutch engagement about 300 to 400 rpm - just enough to get rid of the sluggishness, but it's still very ride able on tight woods trails. I think it would handle a 120 main jet without any problem, and I'm going to try it the next time I'm at the local motorcycle shop to pick one up.
I'm thinking about putting a pipe on it, but I'm concerned about the noise - I don't want to **** off the neighbors! LOL! I've heard that an aftermarket pipe with a 400 Scrambler muffler makes a good combination to both make more power yet keep it quiet. I'm still researching that one. Has anyone else heard of doing that?

On some lids, where the scoop part goes into the lids, the opening on the lid is smaller than the scoop itself. You can cut the opening on the lid a little bigger. On mine, I also have two holes drilled near the back of the lid. Kinda over the air filter. I did this on my trail boss too. And forgot about it just before I went into the creek. Luckily, the water wasn't deeper than the lid.
I don't have any pics of the mods here at work, and this is actually a yamaha lid, but you get the idea of the hole drilling part.
