Here is a list of all mods done on my hawk 250,

1st change oil and chain after buying. I went with a D.I.D 428 130 chain.

2nd change sprockets from 15-50 to 17-45, this made probably the best difference in top speed.

3rd re jet carb

4th modify air box intake, noticed hardly anything with this mod. Maybe more noise but couldn’t be sure.

5th Swap speedometer or just use trc app for smart phones did both. I think the app works better.

6th change spark plug to ngk (2202) DPR8EIX-9 Iridium

7th swapped my rear sliders to washers and bolts, chain seems to rub on the factory ones. (This could be an assembly problem)

8th swap chain guide.

9th visual mods. Used acetone to remove all “hawk” stickers and paint replaced with my own stickers

10th bought but haven’t installed rack and box.

11th in the process of tracking down black panels. If you know of where I could buy from?

Beginning top speed 50ish not sure where my rpms were but they were screaming.
Ending top speed 64mph seems to coast comfortably around 55 with no screaming.

Now my next task is modifying the exhaust. I was curious about replacing? Or has anyone messed around with removing the baffle or drilling holes? And if so what kind of sound/performance increase did you notice?
