Yamaha WR250 on the Dyno fitted with Dynojet Re-jet kit.

It’s not only sports bikes we work in here at the shop. This WR250 was awfully rich but with a new jet and a needle changes the bike is running so much better and now holds onto the power much longer.

sound is so sweet on those older wr’s. newer ones just don’t have that same visceral tone.

Chart is really blurred, but looks like hp was around 27
mid rpm range. Not bad, what was it before the rejet?

Re-jet was worth it I'd say..
