I'm wanting to do a Stage I upgrade on my 2010 SG. I want to go to true duals with CFR's but I've read a lot about the CFR's being hard to tune. I was also going to go with the new Dynojet Power Vison tuner or the PC-V. I don't know a lot about the PV because it's new and there is not a lot of feedback yet. Wonder how user friendly the PV is? Does anyone run true duals with the CFR's, a turner and air cleaner that could give me some advise or suggestions? Thanks for the help!

 

I have CFR's, dresser duals, PC-V, and AC. My bike runs great, but I believe it's because I had it dyno tuned. Before I had it dynoed it ran good but nothing like now.

 

i have CFRs with a thundermax true duals and stage 1 bike ran great i just installed woods 555 cams runs good but it does have a flat spot when going on the throttle. a forum member called (brypink) mentioned this on another thread about the flat spot while dyno tunning. he was right i havent had a dyno but thats why i bought the thundermax so i dont have to dyno. but iam happy with the end results just my 2 cents.

Where did you guys get your CFR's at? Do they have head pipes too?
