I love watching videos of Apex.
My favorite has got to be the 500 day from a couple of years ago.
Apex looks like an awesome place to ride.
Unfortunately, there's a lot of water between us
That Zook looks like it handles really well, what year is it and what's been done to it?

sorry mate havent been on for a while been busy with a new job and such, its a great track to ride probably the best specialist practise track ive rode, my bikes a 2009 model, but sold as 2011 over here, and ive got softer springs for my weight and a fox rear shock handling wise, and just a dep pipe and some smoothing of the ports done with a file in my garage is all the engine work

Cheers guys, the bikes running spot now, it took some effort to get it going well, the pipe wasnt sealing around the barrel well, but its going sweet now, and sounds much crisper. Yeah practise tracks usually have them horrible fences, but race tracks are usually made more sensible

Ive gone the other way, after a few pairs of mx trousers with leather in the knee ive started buying ones without the leather, it cracks and goes hard in the wash and rips way before the rest of the kit, my old no fear kit had leather knees, maybe 3 year old kit? I think it was no fear electron?

The way i understand it, is the difficulty in getting the necessary information to the computer, how do you monitor the fuel air mixture and prevent a lean situation. I'm thinking the usual sensors wouldn't cut it ie lambda probe or air flow meter. I'm thinking it would be very hard to manage, especially with the more variable throttle input and direct drive nature of dirtbikes.

Food for thought: What information does the carb have access to?

A carb doesnt need information as they are designed and set up to work alongside engines, the engine sucks and the carb gives as much fuel and air as your right wrist is telling it to, but with injection, the engine sucks and the injector tries to know how much fuel and air to squirt at the engine given throttle postition and engine speed etc, so the carb needs no information other than the cable pulling the slide up where as the injector needs to know alot, but you do have a good point.

This new fangled DI business seems all a bit over complicated, ive never like fuel injection and never want a vehicle with it, just give me a carb and a cable going to my right hand and ill be happy!

To find out what the clickers do, turn them all the way in and bounce up and down, then all the way out and see what changes

Gear box oil really often, every 3 race meetings usually, the handbook says 5 hours on rings and 10 on a piston, but I change the piston half way through the season and at the start of the season, and change rings once inbetween doing that. Not sure on hours. The bike is a 2011 rm250 and I race A class mx, and do the odd enduro for fitness

My view is that the genuine piston is the one to go for, why skimp on something that important? Ive never heard of oem pistons being the wrong clearance or exploding, and if you think about what the piston is doing, why not put in the one thats designed to be there from the factory? Fair enough skimp and buy cheap plastics etc, but for the piston its best to get genuine stuff.

37hp at the rear wheel will get 100mph with gearing changed and sat on the back mudguard with head down on the tank, but unless they are geared stupidly high it wont do 100 out of the crate, and if you have cash in your hand in a showroom the salesman will tell you anything you want to hear to rip the money out of your hand

When I was 15, I moved straight off an 85 to a 250f, and it was proabably a full season untill I was getting the best out of the bike, had the 250f for 2 years, but sold it to get my rm250 in january, I think having the 4 stroke made me appreciate coming back to 2 strokes more than if I never had the 250f, I think I would keep thinking about how good a 4 stroke might be had I not owned it, but I think i learnt to ride on the 85s like most people do on 125s, me and my dad made the bike as snappy and revvy as possible and I had to ride it hard to make it go, was loads of fun screaming that 85. There are still loads of kids getting off an 85 and onto a 125 in england, but then there are the ones getting off a 65 and onto a handa 150f...

I wasnt looking into buying any, ive got a fox rear shock set up really well and my forks are working perfect, I was just wondering how they can justify that sort of money for the stuff

Its really difficult to measure sag on the front forks theres a lot of sticktion on them when your stood still, so its best to talk to a suspension guy and see if your body weight needs a harder/softer spring
