So the holy grail of my 100cc vintage motocross obsession has to be the Mini Elsinore. I've been drueling over these things for a while and getting one is damn near impossible. So what is a guy to do? Build your own I guess.
Modified stock 75 CR125M

frame Compared to stock frame

Shock angle with 12.5" shocks

Someone else actually started this project and I will be finishing it up. The front end is my main concern right now. I'm actually considering trying to bolt a complete 1980 cr80 front end on to this thing. I realize this is cheating but it could save a ton of time and money.
Anyone have any tips or suggestions?

Can you tell me if the 77 125M forks are the same length as the early 125M forks?
I see on one of your bikes it says you didn't shorten the forks?
Also on the Jeff ward ad it says they used 12.5" shocks in the picture then later in print it says 12 1/4. Any idea of your shock length? To go any longer I'm going to have to make the rear Triangle section more acute to get the shocks to lay down (seems possible if need be.)
This things going to be more a of a pitbike than anything so I'm not too worried about travel but I would like the thing to function well, sit even, and look good.
Also I have a few questions on your bodywork. Your rear fender looks proportional to the rear tire and some I've seem look huge. I was hoping you could fill me in on what you used. I have a few NOS mini mudders around here so I'm good on the front. It also looks like you used early 125M side panels on 1 and 76-78 ones on the other?
How about seat and tank? early 73-76 or 77-78 stuff? I have a 73-76 "RC replica" tank with the threaded fuel cap that would probably be sweet on this thing.
Right now I'm just trying to mock some different setups up to see how it's going to look and function
On the racebike it uses a stock 74-75 rear fender that has been cut and trimmed to fit the C&J frame. It uses stock 74-75 side panels that have had a little minor trimming done to them to fit as well. Those side panels work a whole lot better than the later model 76-78 panels that flare out for the shocks. Those are really in the way if you were actually riding the bike.
Tank and seat are from the 74-76 XR75. That's what the C&J frames were built for so before you weld everything up you might want to test fit those.
Do you know the length on the swingarm? Are you planning on using a 16 in rear rim? And when you weld the swingarm up will it have the oversized piece of tubing on the outside of it as in the photo or will you find a smaller diameter piece to use as a sleeve on the inside of the swingarm tubing?
I will be using a 16" wheel but I may try and figure out a way to use an XR100 rear hub and spokes laced to an aluminum rim. I contacted Buchannons about lacing up rims to the Elsinore hubs and it involved drilling the rims etc. and is very costly.
I think I will use the stock length 74-5 forks with the 13 Inch shocks.
I have a ton of 74-76 XR stuff and even a "RC replica" 75 XR tank with the threaded gas cap etc. so that will not be a problem.
Did you purchase new frames from C&J or find some old ones? I tried contacting them many man times and they don't seem interested in getting back with me.
Thanks again for all your help man!

For the 16 inch rear rim, search for one on ebay off a big wheel 85 or 100. Just make sure it's a 36 hole. If you drill the holes at a little more of an angle, you may be able to use the stock CR125 rear hub and spokes with the spokes layed over at a cross 4 pattern instead of the stock cross three. I have one old mini elsinore wheel at that looks like exactly what they did with it. It might be worth a shot. I had Buchanan drill rims for mine and make up spokes for them. Definitely not cheap going all new.
The way you have that frame cut and fit back together it is going to look like it came that way from Honda . Pretty damn cool.
Thanks for all the advice Newmann!
Right now I need to find an entire 125M front end and some 13" shocks.
During 75-76 ,there were at least 8-10 various mini elsie's that were ridden in our 100 expert class in District 8, and a few amatuers had them as well. Bet there are still a few floating around here.
Newmann, would you happen to have any pics of your other minis? I'm looking for ideas and inspiration and I must of looked at your bikes on vintage factory at least 100 times so far. I would love to see some of the others.
I'm also going to make the rear triangle section more acute. This will allow me to get a better shock angle with the 13" shocks. When I look at the purpose built mini elsinore frames they look to be built that way.
Here's the one we did with 13 1/8 inch Works shocks and the forks at the stock length. Without bodywork.
Finished, with a T&M head.
The other one with shortened forks and 12 1/2 Mulhollands. Full built FMF 100cc boost ported engine and Mototek CDI.
