Technical / Will this work?

« on: December 20, 2012, 02:49:47 AM »

Thanks beaner , I've been down that road and it is to narrow. It needs to be 22 mm wide. Yes I've checked all the sources. I'll find out next week after Christmas about a complete MX 1 lower end that has the 15 mm crank in it. I'm just pondering of weather to bag the 125 or go for the 250 which has all the parts for many years.
    There was that time when money flowed a little more and I would'nt hessitate about putting a new rod in it. But I'm trying to have more patience and weigh out
the future of this bike. Thanks again

I was going to go with the boring out of the piston and the plastic retainers but it won't work with my port setup. I'm still thinking of trying a bushing and having it made of 0-1 heattreatable tooling steel. I am getting the machining for the bushing for free and I will do the heattreating my self. A $900.00 dollar vintage bike is not worth a new rod and a total of about $300.00 dollars for crank work. This vintage thing can get old fast.

I have a vintage 125 Can Am, And litterally there are no oversize pistons available from anyone. Can Am used a 18mm wrist pin on there 125 bike after there first year. I can use a modern piston such as a YZ 125 with a 15mm wrist pin if I make a 3mm steel bushing to take up the space of the 18mm wrist pin. Oh and I have checked and there is no such wrist pin bearing made that would take up the space. Question do you think this would hold up? I could probably send it off to a person who does crank work and have a 15 mm top end rod put on but at some point I have to say enough of trying to keep this motor going. Thanks

Well I'm trying to wrap my head around this and understand how it works, If the fuel is being placed in the injectors and not the rotary valve via a carburator.How does the rotary valve work in this application? Thanks

Uniflow did you put the hole in the upper rod end of the crank? If so was it hardened and what did you use to do it. Thanks

Yes I believe that Stusmoke hits it on the head when he asks if anyone knows any numbers for the factory two stroke, It's like in the mags now they'll try every hop up part on a 4 stroke and dyno them but do you ever see a article on the 125 and what they can get out of them? And actually have them dyno'ed

My problem with the article is that there constantly checking every mod there is with a four stroke and then dynoing it. Well if this intellijet mod and bored carb was so fantastic you would think there would have been a Dyno test to back up results. If I was the Mfg of it and it worked as advertised I would have even paid for the Dyno.
