Bonneville America Forums Forums Technical Forums Performance Mods CR-S Carbs installed w/ Dyno

Well I got the carbs installed & onto the dyno. Take a look!



I picked up around 10ft/lbs right where I want it, which is great! But I also lost HP on the top end... She is still quite rich though so I am not going to change the jetting until I swap the TORs for something less restrictive. I'll probably put pods on too.

128 mains.

Next up is the pipes & igniter box, as soon as I can part with my bike for that long!

For the record it is running awesome! The throttle response on the roundslides compared to the CV's is fantastic. & the extra torque is very noticeable. Plus she sounds meaner...

Hey, good progress. I recommend that you go to pods and do the 813 cams, with the TPUSA igniter remap. You won't lose anything down low, and you will gain a bunch up top. Until you do the cams the top end is going to be flat.

The reason your power is down is because of the jetting. And the cams

Well as stated the igniter is next, followed closely by more open pipes & pods.

The next step after that is going to be the hi-comp pistons with cams. I don't think I'll go 904 as it is way more cost for a very small displacement increase. But that is more of a winter project.

My set up with CR Specials 118 main jet, needle rised clip 3rd position from top with 904cc and rubber belmouth on airbox.....little bit to lean will change for 120 main ..BTW slow jet was changed as well but can't remember what size
