Brock do you have any bikes that run on ethanol (e85), can you make a video about how to tune one please ? Cheers.

@@arkama67 Hello. We should have V4 on our dyno before too long. Most (if not all) motorcycle fuel systems cannot supply enough volume to properly run e85. Once you get into swapping pumps and mandatory bike specific tuning - its a race bike and we don't mess with it. Instead, we use VP MR12 fuel - it makes more power (normally aspirated), the OEM fuel system is fine and you can simply switch back to pump fuel if you are caught out on the road and can't find e85.

Can you do a video where you tear the motor down after using one of these filters long term? The big discussion in the community is about whether these filters pass too much debris even in a "clean" environment and if that is damaging the engine or not. One tear down video is all the world needs to prove this one way or another.

This long term test demonstrates that the engine has maintained it's horsepower levels on the dyno consistently over time/use...so it's clear there is no "damage". The bike now has 32K miles and runs fantastic - I'll schedule another update soon.

i saw there is small gap around air filter because air filter is made from very hard plastic material and cant seal space around filter to secure all that incoming particles. K@N offer special paste which can seal space around filter.but these P08 F1-085 was only prototype.today version is made from rubber which seal much more! and can solve that issue with particles on throtlle bodies as well.one week ago i ordered my P08 (pm05s) for my tuono 13 v4r aprc and came made from rubber as well.best on market.i use BMC filter before.:) now i got more flow without oiling!

interested to see if a japanese or australian market bike were to be done at your shop and what you'd do to it to extract some power. here in Aus all sports bikes, such as the zx10r and similar bikes, all are tuned to a minimum of 95RON. Lowest RON fuel you can buy at the pump here is 91RON with 95 and 98 being readily available. Bought myself a 2007 gixxer 1000 with 24000 miles (40000kms) after selling my Ducati 848. replaced the oil, air filter (replaced with oem) and spark plugs and found that i definitely regained some mid range torque (most likely from the air filter replacement). went to give it an agressive squirt and found myself in a 1 wheeled situation haha. i'm usually ok with travelling on 1 wheel on the odd occasion but i didn't expect it to pull that hard hahaha.

.....and, another great video with lots of knowledge and experience. I wish you still did one-on-one individual bike dyno tuning. My last checkup, the dealership removed my Sprint filter and replaced it with a stock/OEM filter citing "too much debris" in the box. Same filter, different region. So, question: Will going from Sprint back to stock OEM cause any mapping issues with Air/Fuel? More specifically; will it run richer or leaner with less air? I noticed more decel popping but that may be due to a winter tune and high heat summer. And, should the bike be retuned for stock/OEM airflow? I noticed my Dragy blue speed line was not as smooth as with the Sprint. Bummer.
@BrockDavidson3 жыл бұрын
The stock filter flows less air, so the air fuel ratio will be richer. This can also create more decel pop since there are s more unburned fuel in the pipe during decel. Easy fix is to put your sprint Filter back in.

What I currently have is a k&n filter (not sure wether race or normal style filter), what my main question is, is the p08 (normal not f1) a better alternative to the k&n. Or would this be such a negligible difference that it would not perform any better or worse? Thank you I’m having this dilemma and cannot figure out how much air the k&n filter passes trough. And the p08 as far as I saw it was 5000 l/m/ second

Okay, I read the article. What it was explaining makes total sense to me and much of it I have known already. Next question: does the owner's manual on the ZX-10R specify a minimum 89 octane R+M/2? Most bikes I've owned with at least 12.0:1 compression say minimum 90 R+M/2. I suppose that's partly the manufacturer saving itself from litigation in case the user happens to mix some lower stuff. Do you have a set scale of absolute octanes that YOU personally at the shop use for a given compression ratio? I downloaded a 2016 ZX-10R ABS owners manual off the Kawasaki website and the tag specifies "minimum of 90+ RON+MON/2" with 13:1 compression. But ironically it's the same sticker for a Z900 which is 11.8:1.

The best filter for your application depends on your goals (go faster/ease of cleaning/maximum filtration etc...) The P16 is a full race filter and it's being phased out as the P08 F1-85 flows and filters better. If you live in a very dusty region, the P037 offers maximum filtration with quick/easy /no mess or wait 'shot of compressed air' cleaning.
