What are you guys running as far as gearing goes?
I was at 14/52 very tough to keep under me.
Now running 15/52 and the bike seems to pull all gears longer
And it's more predictable on power delivery for me .
85 motor 05 frame. Jetted , on the money
Happy with it for now, want to know what the track ...

pull the flywheel, make sure the key is not sheered and rotated.

Kuma,
Thanks for the reply, the key was not sheared. I did find a spot where one of the wires going to the CDI had at one time shorted against the frame
In the old chassis. A direct short can't be good for a 28 year old CDI.

I like the black engine, looks good. What hell are you running on the back, looks like a 52 tooth or maybe it's just the pic that makes it look huge!

Yah, it's the original gearing on my sons 250f

This is how I drilled the case on my 85 motor for the yz250 bushings first thing I did was drive the factory collar out with a punch.

My brother & I built two at the same time, mine is an 85/05 frame
His is an 85/06 twin pipe frame( last pic )Eric Gorr mods

I'm having issues with my brothers 85 cr500
It makes spark but not at the correct time I think (you kick it over not even a pop)
He purchased the bike non running ( owner told him it ran)
The question I have is could anyone tell me the testing sequence to check
All the electrics on this motor? Any ...

I just used these collars on my conversion& drilled the case (assembled)
With a 7/8 step drill worked great.the collars are tight and the correct size to fit in the 85 case. I'm installing a 85 motor in a 05 crf250 frame.
