I don't let it sit in the tank longer than 48 hours. After a race weekend I'll drain the tank Monday morning and run the bike on pump gas to make sure it's all out of the system. I've heard VP eats up fuel pumps if you let it sit too long.

The bike hasn't shut off because of this issue. Whenever it happens I'm usually pinned on a long straight away. Then, out of nowhere, the bike bogs for maybe 1/4 of a second then before I can let off the throttle it stops bogging. After that first bog ... more »

Thanks, man. I'll borrow the fuel pressure gauge from my car (currently mid build so not running) and I'll watch the pressure throughout the day. Might find a way to mount it to my bars, haha. Regardless I ordered a new fuel filter. Hoping that's the ... more »

2014 yz250f The bike runs as expected when I first get to a track. After 3-5 motos (5-10 laps each) the bike starts to bog hard while on the throttle in high rpm's. It does it without warning. If I let the bike sit for a day it runs fine again then 3-5 ... more »

Drum looks very smooth. No obvious wear marks. We're mostly likely going to end up replacing th entire trans with a 2013 trans. Forks, gears, drum, and shift shaft. Only difference is the sprocket side is slightly bigger so need a new bearing for it ... more »

My brothers 2012 Rmz250 will shift perfect 1-2-3 but when you try to go into 4th it will jump back down to 3rd then when you shift up again it will be in 5th. It will stay in 4th if you don't give any throttle or if you only give it extremely light throttle. ... more »

So it's the right spring? Any reason why it's so much shorter?

Thanks everyone for the replies! Extremely helpful with all of the input. I think I'll ride my MX bike stock besides putting handguards or bark busters on for the first race and see where things go from there. And I'll be getting a camel pack for sure. ... more »

I'm in Delaware so I'd be doing a lot of PA races if I got serious with it. I am most often top 3 in open B on a 250f in MX. Would my class in MX force me to run B in hare scrambles or would I be able to run C in my first race or 2?

Added reply in a thread Hare scrambles 5/5/2018 10:28 PM

I was thinking and hoping it would be as simple as that. Beautiful thing is I already run my gears pretty tall for mx (46t rear 13t front) so i think that would work fine. Also I heard something about adjusting the rebound to the softest setting if I ... more »

I've been an MX racer for 16 years now and I'm looking into trying hare scrambles. Was wondering if anyone had any tips on how I should start off. (Ex bike mods, first race day, how to practice) I'm definitely going to get bark busters and a second set ... more »

I have an all stock bike besides a high compression piston and upgraded valve springs. I'm looking towards upgrading my 2014 yz250f to get more power out of it without upgrading to a 450 yet. Was wondering is it worth getting the head ported and if so ... more »

It's because pros get parts custom made for them only. We could never get the same parts as a factory rider unless we were s factory rider lol
