New exhaust?

538 Views 7 Replies 4 Participants Last post by  Joseph12
Hi guys, thinkin of getting the yoshimura rs3 exhaust. I red that it may need to retune the engine with power commander when new exhaust is installed. My question, can I install this without adjusting or retuning? my knowledge with bikes is very limited but trying to do things myself..thanks

You’ll be fine on an otherwise stock bike. It would make a bit more power with the proper tune, but you won’t damage anything…
Do you have a tuner on the bike? If not, just do the ECU reset & go for a ride varying the throttle openings to allow it to dial into the exhaust change.

Thanks guys..think I may be able to reset the ECU at least.
I have a two brothers S1r and K&N filter, stock box. Sent my ECU to DHM, he fattened it up nicely. It was only $100 when I did it a couple of years ago. Turn around was very fast, but I did it off season. Nice easy stage one upgrade.
The little 2015 easily gets 62 63. I'm 180 lbs. and 3 up on rear sprocket. Down hill with a stock sprocket 4 or 5 mph more probably. Bike is stock otherwise.

Yeah 60+ is a good speed. I’m not really after anymore speed as I only use it on store runs. 45-50 mph is pretty much all need. It takes off fast enough that I can get in front at stop light.

Agreed, you have the right idea, Groms are meant to just cruise around. I do like the steeper gear in the rear. It will drop your top end, but does help you get out in front at a stop light.
I have a Honda rebel 500, which is by no means a real fast bike, but after riding the Grom for a day, the Rebel feels like a rocket ship. Do love my Grom though.

Rebel 500 is nice, unfortunately with 2 back surgeries seating position on the rebel really hurts the back. The Monkey is light enough and the upright seating position plus padded seat keeps me riding.
