gen 1 conversion cr125 bushings and washers HELP

[davidonmars]

so doing a Gen 1. For the swinger bushings to properly center the motor the 02+ cr125 bushings and collars/washers properly centre the motor correct? 54 and 59mm right?

Use all the stock gen 1 parts, plus 2 spacers, 4 and 6mm I think they are.

i was wold instead of using the spacers i could run a 02+ cr125 swingarm bushings and washers i just wanted to confirm

[Nodge]

Can't help you there, I have no idea.
Maybe I'll go that way if it works.
I was going to get case bushings machined with the extra width on each side so I didn't have to deal with the spacers.

Option 1:

Take the time to read through the builds, all the info you need is here!

Options 2:

Mock it up with a straight edge and current bushings + washers, take your measurements (bushings + washers) and that is your swing arm bushing lengths. Look online to confirm your beliefs about the gen 3 bushings (dimensions of bushings will be given on the parts break down diagram available on-line)

Personal opinion (not that it matters):

Take the time to read through the builds as it will likely answer other questions you may have and give you further confidence during the build process.

I have read everything over and over but I get conflicting answers, hence why I am making this post.

4 & 6 mm spaces is correct for the Gen 1. If your looking at the Gen 3 125 spacers they are 54 & 59 mm. Believe Gen 1 and 2 bushings are the same which should measure out at 49mm on both sides, but verify this one your bike and replace your bushing length with the red below.

49mm + 4mm = 53mm
49mm + 6mm = 55mm

So you need 53 & 55 mm spacers if your bushings are 49mm. So either use spacers or get the gen 3 125 bushings and part them off in a lathe to the proper length.

that helped thanks. so 4 and 6mm then? the drawings show 4 and 7mm. I just want to make sure this is right.

[fmikhele]

1 mm is about 1/32" of an inch. Pertaining to a swing arm bushing - Nothing to loose sleep over.

[hoofarted]

So 4 and 6mm then?

Yes.

[davidonmars]

Does the 53mm one go on the sprocket or kicker side?
