Have you got a JRF on your bike Total.?

Na I havent got one TMKIWI, thought about it but they're pretty pricey and i don't really mind the power delivery to be honest.

I'll have to disagree on this again.. Yes the V Force has a bit more surface area.. but they are also known to suck reeds out of position. (They are not screwed to the reed block like the Rad Valves)
The V force is also a 2 piece unit (the block and intake) extra o ring/gaskets more room for failure (DNF)

We have done tons of testing on Jeremys YZ 250's with Boyesen and V Force. No more V Force.
KTM does thorough testing, for them to switch to Boyesen there was a good reason and it's not cost savings.

Vforce 2's are where its all at.

Single piece manufacturing
Properly fastened reeds
all the issues you mentioned there werent a problem on the 2's

Thats why a few of us have a decent Vforce2 stockpile!

but in saying that I've used 3's and NEVER had an issue

Interesting you say that, i was thinking of upgrading to vforce 3. My 09 model didn't come with 3's. I thought it might be a useful upgrade? I'm not even sure which model vforce i have, the reed blocks grey with puple vforce reed systems badge.

I have to say that i've never had any trouble with the vforce on either of the bikes i've used it on, no reliability issues whatsoever.
And in fact the time i have fitted a rad valve to a bike it needed a bit of work with the die grinder to match the joins in the manifold and get a nice smooth flow from carb to barrel. Think i'll stick to vforce. Plus i've never seen dyno runs that favour the red valve but there are a few that favour the v force.
Also thinking maybe your sponsorship choice might involve boyesen's larger product range and rider support?

How much oil are we talking about here? Sounds to me like it's just the pool of 2t oil thats supposed to be there.

Sounds like your right hand side crank seal is leaking.
Is it using trans oil?

Technical / Do you REALLY have to replace sprockets and chain at the same time?

« on: April 15, 2013, 03:10:32 AM »

Yes definitely replace the whole lot at once. i'd never run new sprockets with an old chain or vise versa.

Yeah rebuild her, it would be rare for a motor to be that trashed that it's not worth fixing.
I don't think they were electro plated bores either were they? that'll give you an option to oversize if you need too.

General Two Stroke Talk / Is there a link between the bike you choose to ride and intelect?

« on: January 31, 2013, 09:20:44 PM »

stusmoke. your definately right they are easier to ride. however there have been numerous test indicating that riding a 4t vs 2t allows a rider to make less mistakes albiet not a faste lap--reference transworldmx.com 250 vs 250f a few years back.  and riding a 250f or 450 you still have to ride the top of the power. have you ever heard a pro race by that wasnt on the rev limit? and clearly you dont watch RV2 race cuz he uses the rear to get through turns so fast. even on a 4t you have to steer with the rear. however vs a 2t you get more front end traction due to the extra weight and slower engine speed not spinning the rear tire as quick.

look my point is this. this site sometimes sounds more like a bunch 4t hating Nazi's then someone who is trying to help the sport. I've been on both sides. ive ridden every brand and every current engine size. i love riding 4ts and 2ts and both have pros and cons. the biggest factor right now is COST plain and simple. and  this give the nod to 2ts. that is why we/this sport needs them. what is needed is OPTIONS. like auto racing there are options for the high budget team and the low budget weekender. however our sport needs the pro level to reflect this. i wrote all about changes i felt would help the sport.

Ok first of all, being at the top of the power on a 4 stroke and 2 stroke is a whole different universe. Four strokes can simply be taken a gear lower. You shift when you feel like it and use the clutch in rare instances during a race.

Secondly, I agree about people here sometimes getting a little excited about the 2 v. 4 argument. We're all guilty, myself included. But at the end of the day, when you look at the big picture, todays definition of the four stroke motocross bike has NO place on a motocross track. Lets assume for a moment that you have a blank cheque for all your bikes. That takes costs out of the equation. And lets also assume that motocross around the world had the ridiculous rule of double displacement revoked. if its a 250, it gets run in the 250 class. Diesal, rotary, two stroke, four stroke, irrelevant.

What would you choose motoman? Would you choose the bike that didn't advance your skills very well, made you a lazy rider, wasn't as much fun to ride as its counterpart, harder to start (KTMs four strokes excluded here of course), made an obnoxious sound that carried a very long way, was heavier and slower?

you speak as though you race alot, do you? you also speak as though you have raced a 450 at a high level, have you?
alot of the statements you make are dead wrong. my friend who raced semi pro used to go through clutches just as fast on his 450 as he did on his 250 2t.

There were lots of runaway victories during the 2 stroke days, 4t SX is hardly cruise control like many on here imply... I am not a big fan of the circus like vibe and much prefer the outdoors. But, I still watch because dirt bikes rule and there is no other bike racing option... This past weekend had some great racing and I look forward to more.

agree totally

General Two Stroke Talk / 2007 CR250

« on: January 03, 2013, 09:06:27 PM »

there is a question in the newest mxa about the 01 vs 07 cr engine...which one would they use if money wasnt issue and they went with the 07....it was in the ask the expert section...they didnt elaborate too much, but i guess a good builder can make the 07 better than the 01....

Without a doubt it has more potential, but the 01 was better off the shoowroom floor.

How do you know this? Have you owned both or tuned either?

BTW, the A kit suspension was an awesome bonus, I've known people to spend more than that on used A kits. I picked up my bike for a song, much cheaper than my son's CRF250 and its twice the bike.

Three times the CRF
