on my gen-4 I put it right above the head above the Y, very OEM like.

did you weld in one of shanmans coil mounts or something else?

I made 2 peices about 1" long out of 1/4" plate and drilled and tapped holes, then welded those. I'd show you a pic, but my hosting space got all f-ed up. It was essentiallt like the oem mount and loaction, only higher up.

Classic !!!

I'm modifying my tank in the next few days..... I'll take some photos, and do a " Step by Step".....

I'm assuming you never did plumb the spars?
I would like to do something like that to my bike, but add a valve so they would be a switchable reserve so i knew when fuel was getting low.

People must really like this bike.

a fair share of those were mine trying to find what spacers you used. So I guess I should ask: What spacers did you end up using for the rear?

Its in there.... you flip one side to side, and go buy one from a cr250.....

Don't you mean one from a CR125, Bob?

This was all I found about spacers. Prior to this you didn't have it lined up perfect.

the '02+ cr125s have a 59mm and a 54mm bushing. you want to buy the 59mm and use your existing 54mm, just move the 54 to the other side.

Perfect! Thanks

The CR250 must use the same sleeve, as thats what I used

agreed, not like I've made much progress on it this last year but it's sitting on the bunch mocked up with those spacers....

OK this might save some confusion when stuffing a CR500 engine into these frames.

The Std CRF250 04-09 uses a 49mm on the left and a 59mm on the right, with the CR500 engine get a 54mm for the left side and you are done.

The Std CRF450 02-04 uses a 49mm on the left and a 54 on the right, with the CR500 engine swap right to left and get a 59mm for the right side and you are done

The Std CRF450 05-09 uses a 46mm on the left and a 54mm on the right, with the CR500 engine swap right to left and get a 59mm for the right side and you are done.

The Std CR125 02-07 uses a 54mm on the left and a 59mm on the right, with the CR500 engine you are good to go as is.

Part# for the 54mm bush is 52142-KZ4-J40, left side of swingarm.

Part# for the 59mm bush is 52141-KZ4-J40, right side of swingarm.

If any of this is incorrect, please let me know so I can change it before any mistakes are made.

Is this something that needs to be done when converting all CRF bikes? Or, did you do this because of an "oversized" spring?

Both, I think....

I didn't have to on any of my conversions. I think thats just for the fatty spring.

It might be a 250X thing... I know the linkage is different....

I had to do that to all 3 of the gen3's I have done...

Did you have to removed a lot of material?

31170 veiws it's getting up there Bob.

My 2004 CR250 conversion did not require this. I was running a 5.4 spring too . Maybe I got lucky ? ? ?

DPinDet

Thats strange that the results are so hit & miss...I hope I don't have to.

I didn't have to do it on the '04 SH 500AF (CR250 based) I had but it was close. If I went with a heavier spring, I feel like it would have needed it.

Just check it when you get to that point. If it needs it, it needs it. No big deal.
