Hi all, I've been looking into getting my bike dyno jetted possibly stage 2 as I have an aftermarket air filter and exhaust system but I'm wondering if it really makes a lot of difference?! I know they say it can make an 8% increase in power but they are selling them so I'm not sure Wether to belive them! If n e one has had this done or done it themselves I'd b great full of some information on the subject cheers

 

I put a Dynojet stage 1 in my 1995 900RRS also replacing the stock air cleaner with a K&N filter. I lost the dyno read out but it was about 4 – 5%. Best of all was the improvement in low and mid-range which made the bike easier to ride when touring and was well worthwhile.
