Do you use the stock airfilter holder with the backfire screen in it?

optimum air fuel

Ok. No, for optimized performance it's between 12,8 up to 13,2 depending on bike.

Yes, its the stock airfilter holder but we don't have any backfirescreens on our swedish models.

Thanks man! Dyno's are cool, I had lots of access to one when I was racing street bikes. THey are great for jetting and airbox mods, oil levels, oil types, fuel, well, you know.

Impressive for sure. Weird thing is I just got my Cert. of Origin and it states 59HP on it. I was like &%$#@!???

I'm sorry. I can't tell you. All i know is that Dynojets jets are larger than other brands and that the common way of sizeing jets is by using mm's so a 160 Keihin is 1,6mm in diam but Dynojet uses a flow value.

Just a quick question about fuel..

I know for a fact that in Europe and Spain they have "Hotter" Fuel out of the pump than we have here in the states. i guess what I am trying to say is that it is not totally impossable to reach those numbers but you would have to get a loan for the motor work and run "race fuel" to make it happen.

just my .02

Hehe, maybe that's why we have to pay more than double the price for the fuel than you guys do? I tested the bike on a track this weekend and holy sh*t!! It flew away like a rocket! :thumbsup:

How much more HP do you think you got out of it in the dyno, than if you tried to tune it by "ear, feel, and spark plug colour" on the street/track ? hehe..

I really would like to take mine to a dyno to tune it one day...

Ok. thanks alwas good to know. I bought this bike last fall after driven it for 10min at the company that I work. About a week after that I fell pretty bad with a bike and crushed a few bones in my foot and broke three other bones so I've done this mods while healing. That's why I didn't put it on the dyno before...


That is a true die hard, only broke a few bones, so we better make her a little faster :crazy:

That's really hard to say. When I tune in a dyno I start from idle, then goes up to pilot jet, needle position and then finally decides what main jet to use. It's very hard to feel on the street how lean or rich a bike is. After all that tuning's done I does some roll-ons on 4th gear to se the response and to get the graph that's shown on page 1.

Do you have the numbers for the 525? What does the curve look like compared to your WR?
