Last week I had the following items installed at my local dealer…

• Yoshimura TRC Slip-On
• Dynojet Stage 2 Jet Kit
• K&N High Flow Air Filter
• Area P Exhaust Hanger Bracket

I've put about 400 miles on the bike since I got it back and couldn't be more pleased. The dealer did a great job tuning the bike and it seems to run great. With this combination of mods, I've noticed an improved throttle response and just an overall more enjoyable powerband. We're not talking a lot of power increase here… after all, the bike is a 250, but it just seems more fun to ride now.

Sound: The sound of the exhaust is quite a bit louder than stock and does take some getting used to, but it sounds great. The bike finally sounds like a sport bike and not a lawn mower, which is part of the reason I wanted to do this mod. Yoshimura included a silencer with the exhaust, and I might try that out to see if I like it a bit quieter.

Weight: The factory exhaust I removed was just over 11 lbs and the passenger footpeg mounts and footpegs were just over 3 lbs. The new Yoshi exhaust was around 5 lbs and the Area P mounting bracket weighs practically nothing, so I dropped about 9-10 lbs total, which on a small bike like this is actually pretty substantial.

Looks: As far as looks go, the Yoshi pipe looks great, and the Area P exhaust hanger allowed me to remove the passenger foot pegs and it really cleans up the rear of the bike.

NOTE: When jetting the carb, I had the dealer make a note of what they ended up with…
Main Jet: DJ098
Needle and Clip Position: #3
Mixture Screw Setting: 3 turns
