Hi Guys,
First of, let me say this is a great form for CBR owners. I got my CBR back in march and I've been reading up mostly and learning a lot from here. Thanks!

Anyway it seems like my Bike tends to stall when hot (i don't want to assume its the hot stall issue yet). Of course searching the forms made me realize that the stock R/R is a POS.

I do however have a Remus exhaust + K&N filter (and the dude that sold it to me said that he didn't do any rejetting)

so my question is, Can this be a leaning out issue? or a purely hot stall- replace the R/R issue, or a combination of both?

Thanks
Jon
