Is this build done yet!!? It is march of 2014 you know! :cool:

Not yet, waiting on the Airbox piece to get done. Hopefully it will be done in the next couple of weeks...

I have sent out my fuel tank pieces to be hard coat anodized, then I will wrap this on up and move onto the 2013 that I am ...

$120 sounds like a great deal on a pair of radiators!

Sorry, here it is...

The second set of prototype radiators for my 2012 CRF250 with 2001 CR250 Motor in it are done... I have posted pictures of them, as well as the drawing for them in case anyone wants to make them themselves... The guy making them is only going to be charging under $120 a pair delivered.. So check ...

Today My fuel finished fuel tank plates came in from LoudMouth MX!! These things are GREAT!! They only weight 5.5oz and he is selling them for $135... They except OEM O-Rings and use a 2007 nCRF450 Nozzle, O Ring and filter screen. Justin did a super job on this piece. Anyone building a conversion ...

OK, Here is the deal.. I have been on the hunt for the perfect (Meaning non shock rubbing) AirBoot/Carb/Reed Cage for my GEN 5 250 2-Stroke. I bought 1999, 2000, 2001 and 2007 CR250 Airboots. I also bought V-Force, Boyesen RAD Valve & Stock Reed Cages. I wanted to try different combinations to see ...

Here is something like what the Tank Piece will be like. Uses Stock O-Rings and the bottom tank fitting from a 2007 CRF450...

I pinched this from roosty for my gen 5, instead of the hassle and cost of machining up a plug for the fuel injection pump hole in the tank just get a stuffed pump assembly (ebay / dealer) and cut out the fuel pump leaving the backing plate to mount to the tank. This will allow you to use the stock ...

Getting back to my GEN5 conversion. I recruited Mickey Kessler to do the welding for me as I am not a welder at all. Justin at LoudMouth MX is also helping me by making me some of the custom parts that I need to have CNCed... He has my gas tank and is making me a plate for it that will actually go ...

Thanks

I just started working on this again. Hopefully I will have an update soon...

What do you do to the markings and the original mounts on the back of the Y, grind them off?

I'm positive that is a gen 5 y, I'm re-using 1 now on a customer build. It's a pita on a 500 because the motor is taller than the cr250 so more of the y has to be cut away as well as the downtube for the 500 motor, looks like a billet y is in order for the 500 powerplant.

Thank You for your reply ...

Roostius_Maximus wrote:Willing to settle for a billet one?

That is what I wanted, But I am doing a 250 conversion and all the Billet Y's out there are for 500... I wanted to design one and have it made, but can't find a machinist to make it...

Roostius_Maximus wrote:it looks to be a gen5 250f chassis and the factory Y

It is a Gen 5 Frame, but that is not the Y from a Gen 5... I am building a Gen 5 conversion like this, but I need to know what that Y is off of so I can get it...

I found this picture of a conversion someone did online (it is a 250 2-stroke conversion) Does anyone know what frame this Y is from?

I figured out the spacer sizes needed to put a 94-01 CR250R Motor in my 2013 (2010-2013) CRF250R... Hope this info helps someone-
Left Side (Chain Side) is a 49mm Spacer with the stock collar, Right side stays stock (54mm). The part number is 52141-KZ3-J40 for the 49mm. Interesting enough, the stock ...

I think that is a good idea. You would not want to put tension on the frame and create premature cracking.

Ya, that is what I am afraid of.... It is looking like the 49mm Left side and 54mm Ride side might be the ticket. As I build this thing, I will post all the part numbers and diagrams of the ...

My advice would be to make the spacers with no additional clearance between the swingarm. You do not want to pinch the swingarm at all.

Thanks, If I did that I wouldn't catch enough treads on the swingarm bolt. After looking at it some more, I am wondering if I use a 49mm (stock 2001 spacer) on ...

Thanks, I have a Gen 3 CR250 already. I want a Gen 5, just my preference ....

I tried searching the forum, but didn't have any luck. I am going to put a 2001 CR250 Motor in my GEN 5 2013 CRF250R. I know that almost everyone on here puts CR500 motors in, but I figured that I would ask because there is a ton on knowledgeable people on here and I might have some luck... I am ...

Just wanted to say a quick Hello. I am building my first conversion (and I am sure there will be many more) a Gen 5 2013 CRF250R with a 1997 CR250 Motor in it. I was looking on line for some resources to have some parts made when I stumbled across this Forum. I have been doing a lot of reading, and ...
