If you're still not getting good weld penetration, post up what type
of welding you're doing and your settings. Might just need to tweek
your settings.

Good luck with it.

OK, I know preheat is needed,
Actually, it's not. Welding on these Aluminum frames is considered pretty
light duty and any decent TIG or MIG rig will get the job done without going
anywhere near it's duty cycle. If you are concerned about the tubing moving
around going from cold to hot and back ...

wanted to ask if you're still flying?

Yes. Doing one more year from next month. Plan to start a
countdown clock about six months out

This question is for those of you that have replaced the cradle on your
conversion and used the stock "Y" piece.

I am trying to clean out the old tubing from the "Y" and the frame. So far I
have tried a cut off wheel and a flap wheel on a grinder, a die grinder with a
carbide bit and a end mill ...

Nope, you speak out both sides of your mouth...
Nope! You're being intenionally obtuse.

I said that cylinder angle and center of mass were important considerations
when engineering the engine location in a frame, and that even a few degrees
makes a noticeable difference, and backed that up by ...

Make up your mind.....
Never in doubt. You have enlightened me with your opinion about the
irrelevance of cylinder angles and I have dismissed your opinion out of
hand. Or, to put it in simpler terms, you're free to espouse your words
of wisdom as one of the "leading internet authorities" on Honda ...

If your really all that concerned about the time, effort, blood , sweat, and tears that the Honda Engineers put into the final chassis layout
Actually, I don't think I could give less of a rat's ass what the Honda
engineers did or didn't do.
you would want the two stroke engine AS UPRIGHT AS ...

C/S position has little , if anything , to do with it
True, and the distance between the C/S and the swingarm pivot
bolt is fixed.
Motor clocking will slightly effect the bikes center of gravity, but I doubt its enough to ever notice.
Also true, except the part where you won't notice it ...

If you really want to cut your powder coating cost, do all or most of
the prep work youself. Media blast with AO or Soda, wipe it down
with acetone, plug up threaded mounts with silicone plugs, tape
up the model plate and provide the powder. About 2 hours of labor.
A fair powder coater shouldn't ...

Yeh, the only time I paint a frame is if the owner insist or if the bike
will be a dust collector (show only).

You can powder coat the frame and subframe with less than a pound.
I sell the color matched powders (Tahitian Red, Flash Red, Fighting
Red and Shasta White), for $15 a pound plus shipping ...

Or you can buy a rattle can from here for $16:

I also stock Flash Red powder for powder
coating if you want to go that route.

Just saw this post and if you are still looking, the color code is NH138
and is called Shasta White. Here is a link to coloRite for the paint:

i'd order one, but marked for a 250 makes me worry. the 250 stuff is different spacing.

Not to worry on this one, same part for both bikes.

Thanks for the info. I still want to use the 00-01 cradle shape so I'm going to
try to replicate the 00-01 cradle using the correct 08/09 compatible tubing.

I'll have to find a competant shop to do the bends. With Aluminum, they may
have to use something like hydroforming to prevent kinks. Looks ...

You're starting on your frame before I am, I'm still building the engine.
Keep us posted on the cradle compatibility with the gen 4. At first look,
It appears to be a good match. And as you said, Everything but the
hanger plates will already be correct. You'll need to find a place for
the ignition ...

I'm working on a similar idea using an 09 CRF250R frame and a 00 CR250
engine. I'm still looking at all the options for the frame but to keep the
weight down, I lean toward using the cradle from a gen 2 CR250 frame
instead of a billet cradle. The stock CRF cradle doesn't provide the
needed ...

Dogger Couldnt you buy some used Showas off E Bay and a custom set of triples made to fit your Gen 5?
For a gen 5, I can get the latest SSF and maybe even the new "air" forks. I
can also get these same forks for a gen 4, and the correct triple clamps are
still available. The problem is the shock ...

I totally agree with you about the gen 4 being superior to the gen 5.
Typical to Honda, they took a good thing and went backwards.

I'm in the early stages of a CR250 build and I would prefer to use a gen 4
frame because I think my gen 4 500 is just about perfect. Unfortunately,
I also want to ...

IMO, 19" is best for MX for a bunch of reasons and 18"
is best for everything else.

I run 19s on all of my MX bikes including my 500. The
two sizes swap out with no problems because the aspect
ratio of the tires change to keep the overall diameter
the same i.e. 110/90X19 vs 110/100X18.

dogger

fuk me dont plan on getting any flex in them head stays

I like them! Where can I get a set?

Sweet looking build.

dogger

Looks like a nice clean build. I like the "Bailey" graphics.
Have fun.

I have ridden and raced every year CR250 and 500 since 92. I switched
to CRFs in 04 then back to CRs in 07.

I used OE Showas that were valved and sprung for my weight and speed
until 2000 when I switched to the Showa A Kit suspension, so all the bikes
had the benefit of good to very good suspension ...

The VForce design doubles the reed surface over a stock setup. This
results in improved flow even though the petals travel a shorter
distance. VForce claims improved throttle response and more
power along with longer reed petal life.

From personal experience doing A/B comparisons, the VForce does ...

I was refering to the honda parts not the vforce having issues
OK, that makes a lot more sense. I have definitely experienced QC
issues with Honda castings. Looks like I didn't have any problems with
the VForce and my 500 cylinder because EG matched the intake and
exhaust to the reed and pipe ...

some castings are different and the reed pedals and housing contact the cylinder
I have heard about some quality control issues with the VForce 3s,
though I haven't experienced any first hand. I have dozens of 3s
and each one is identical in dimension to the next. On my 500
with essentially a ...
