  1. Hi Guys, So I recently bought a 1997 XR400. I've done some research into getting more power through some basic mods and rejetting the carbs. Though all of the ones I've found have been for post 98 XR400s so the stock carb set up is a lot different. Usually people are opening up the airbox, exhaust ect. ect. and Jetting their carbs up to 160/162 for mains around 60 ish (I think) for the pilot. However for the 97 model this is close to stock for the jets. So essentially what Im asking (Just to cut to the chase ) Has anyone got a 96/97 (maybe 98, not sure) XR400 and has done these similar mods, and what sort of jetting have to done as a result. Thanks in advanced, also its my first post so apologies if I havent done everything correctly.
  2. As the title suggests, I've been debating the idea of throwing in a high compression piston. It will bump the compression in my 2014 KTM 350 XC-F from 13.5:1 to 14:1. First and foremost my main question is, because I live under 1000 ft and usually run 97 octane REC gas, will I have to change the fuel I run or not? Also, will I have to change out the cams to aftermarket and re-time the whole motor and ignition? I guess I really don't know what to expect so any advice will definitely help! Attached below is a photo of the bike I plan on putting it in.

    Just bought a 2017 650l, couple questions

    I recently got the money to pursue my interest in dual sport bikes and got a new 2017 xr650l. I read the manual and still have a couple questions for some seasoned experts haha. Regarding break in, whats the best mileage to change the oil at? And any other important break in procedures i should be aware of. Regarding shifting, the manual says to shift 5th at 25mph but when i do the engine seems to bog down a ton. What are your common shift points? Also as a stock xr can i run 65-70 down the highway or do i need to do some modding to the gears? Thanks a ton.
  4. This guy has done about every modification to his bike including a Pumper carb, bore kit, new exhaust and air filter yet he says the new ignition iis the "most powerful mod ever" Have you heard of replacing the entire ignition system to a modified one? Here is what he says about it. More info in the link below. "Just recently I have found one of the MOST POWERFUL mods I have ever done! This is a new mod that was completely unheard to me! I am amazed that everyone I mention it to hasn't heard of it! This one single MOD costs $350 TOTAL. And makes the 400 feel like it's on nitrous! In other words: the bike will wind up so fast it will feel like the clutch is slipping! This mod is the use of an ENTIRELY NEW IGNITION designed by White Brothers. This is AN ENTIRE IGNITION system; NOT SOME STUPID BOX THAT JUST GIVES IT MORE TOP END!!!!! This is an entire ignition system with a faster advance curve. The entire timing curve is more advance throughout the whole poweband. Since the XR is a green sticker legal bike it's timing is drastically retarded making it's emission much lower AT THE EXPENSE OF HORSEPOWER and TORQUE!!!! This is THE MOST POWERFUL ENGINE MOD YOU CAN DO TO YOUR 400 (even if you don;'t have the Mikuni 36 Pumper on it!). They guy who turned me on to this mod works at ALL SPORTS HONDA BMW in Grand Junction Colorado. His name is Tony and is one of the sharpest guys I know on all the latest aftermarket tips and tricks for XR's. This complete ignition systems normally sell for $330 plus shipping (and or sales tax). However, I got mine for only $300 delivered and you can too. You can call Tony at 1-970-243-7730 for details. Mention my name and get it for $300 delivered. P.S. Feel free to call me for more details about this mod. I also learned some more neat things in testing even more exhaust systems (i.e. FMF PowerBomb Header etc.) P.P.S. Recently purchased a 2000 650R from Scott Summers. However, the paperwork is a little lost right now so I have been unable to ride it to the dirt as in my state they'll impound it without insurance. Hope to hear from ya! Jay Peters " http://www.justxr.com/info/xr4report4.html What are your thoughts on this ignition modification?
  5. Australian Psycho

    Exhaust Questions.

    I have some questions to clear up, concerning uncorking a 2012 TTR250, that I need to keep road legal to Australian NSW laws. Is it the pipe coming from the Bike or the Exhaust (The Header) that deals with noise I get the impression that it's the Exhaust. I know the Exhaust system is restrictive but is the problem in the Exhaust or in the pipe. If it's the Exhaust, is there a aftermarket one that will help uncork the Bike but not exceed noise limit of 94 decibels? It seems the powercore is loud at 96 without a insert. Also when buying a Exhaust you don't need a full new system do you? As in new pipe coming from the bike aswell, they should mount straight on yeah? Also is it possible to rejet the carb, and do airbox mods, with out an exhaust? Or would it be better to just leave it stock? I know lots of dumb questions but I would appreciate any help.
