Title: After one year, observations and questions
Post by: freewayferg on October 30, 2022, 08:09:52 AM
One year of riding and 15000 miles on 2021 RGL wet head that came delivered with SE stage 2 torque kit. Enjoyable ride that can eat up the miles of open road. I ride at a pretty good pace and this bike allows me to do so, as long as its 80 degrees or cooler. As the temps go up from there performance goes down, pinging on inclines and such. when temps get around 100, forget it as it pings at any attempt of acceleration. The tuner at dealer is no help, says it the best he can do.
 Is this an accepted norm?
 Can I make it better? How? Aftermarket tuner and/or cam? A different brand of motercyle(yuck yuck)!

Talk to another tuner (reputable) about it, I'm sure that have suggestions that will help, as in an aftermarket non EPA restricted tuner and proper tune.

If you're using the SE Street tuner, You should be able to edit the Spark Advance/Head Temp table- it allows you to remove up to 12° of timing as needed for high cylinder head temps.

any data on how high cylinder head temps can get on a wet head with that (or any) cam?  i haven't seen any wet heads in the shop (or anywhere around in NH really) so i really have no idea and would be interested to know how well the cooling actually is on different combinations.

Does it also have IAT vs Ignition?  Asking because I don't use it.

I really don't see any difference with timing tables from wet heads vs oil cooled.  I know this isn't most scientific answer, but it's reason that if heads were kept much cooler.  I could add more timing.

No, it's not very useful. (But the EPA likes it  :crook: )
