X2. You still need to make that cut and move it up a ways to clear the exhaust...

hmm

you dont have to do relocate the Y, you can leave it, i have done it on my first build which was also an 02 CR250R, BUT i couldnt run top springs on the pipe unless i added big mounts to the cradle or something, and it seemed like a ton of extra work hogging out the bottom of the Y over and over and re welding it each time to get it right.... i remember adding little tunnels just to get to the top 2 bolts of the exhaust manifold..... and then you have to remember to tilt the bottom end while you put the spigot manifold thingy on the cylinder before you swivel it in place and i remember getting that motor in and out was a real PIA....... either way, it IS doable..... congrats on the project, keep goin' and you definitely came to the right spot for advice, tips, and support to make your dream bike a reality......

i like this forum a bit more, its less conservative...... and not as many new jackoffs telling you how to do shit they can only dream of.....

You really didn't need to cut anything and you can get away with just taking a bit out of the bottom of the Y to have the pipe clear. Look at my Gen 3 thread for details. Good luck on the build.

congrats on starting with some fine bikes!
You have all the resources and hundreds of conversions to look at, why would you do it that way? the front mounts will be tougher (will have to be gen-1 style) and that Y is gonna be the biggest PITA. no way to bolt on the exhaust manifold and no room for springs. I moved my Y as high as it would go and still had to grind out some clearence for the manifold bolts!
do yourself a favor and check out some other builds before making something you'll regret. the jug will never come off in the bike w/ that setup. Mine just did :wink:
I recommend to find algavas build, I think he only posted on the other site, but I used the same method and couldn't be happier.

x3. I also copied Algavas' build with helpful tips from Danny and others. Coolest bike I've ever owned by far. And, by the way, it's also a 2002. With Algavas' instructions, Shanman's front mounts and the talent of my welder/fabricator, my bike turned out great. And, like Danny says, my cylinder BARELY fits in and out even with the Y raised all the way to the radiators. Happy building.

ok guys well here i am on sunday night the 2nd of august, having spent most the day on the fabrication, here is where i currently am.

starting with that notch that i made in the frame to clearance the water pump, i cut a pie piece to fit my notch and accomodate the new water pump area. enjoy the photo's

then
Image


i opted for the barrel style mounts just because they are so stout!
then i cut my y peice
Image
Image
Image

my new inseam of solid T6

Image


fitted
Image
Image

checking my clearance
front side clearance. (NOTICE) The exhaust flange clearance, soon will be more "sano"
Image

TIME TO WELD IT UP!!!!
Image
Image
Image
clearance clarance


clearance for rear of engine case then re-weled the seam
Image


((((time to make head stay mounts out of 1/4" T6!!!!!))))

Image
Image
Image
Image
(((( so after a all nighter this is where im stuck until the radiators are
done.. stay tuned. should have more photo's up soon!!!!

I wasn't sure how this would turn out when I first saw your method.
To see the pics now, I must say this looks like it is going to turn out really good.

Looks good! You using a single-side stay? Curios - how'd u bend it? Oh - did you try to fit the exhaust springs on the manifold yet? If they rub, you may have to swap them with extended versions.

yes. iam using that single headstay mount and it was bent with a custom die in a cold mandrel press.. the stock pipe springs clear perfectly i wont need the extented ones. we took many many measurements to make sure the springs clear without making the frame look murdered.. will take more pics soon
