Hmmm, interesting, I was woundering where that Aprilia Frame from trade me ended up (I presume it is the same one that went up for sale recently)
Saw it in the back of a ute on Sunday, pretty. Shame the sprocket etc is all on the wrong side.
Chambers has made a scale drawing of the FZR swing arm and sprocket showing maximum travel and the frame mounting points so he can design some engine plates and get the frame, engine, sprocket and swing arm relationship sorted properly.
Not as easy as turning the wheel around and drilling holes. The swing arm is a piece of work.
The plan is to use an Aprilia engine, well at least the bottom end. This way we get a six speed gear box and the drive on the right side anyway. Work on using a RG400 cylinder and new chamber. 100cc water cooled six speed is the end result. Sounds easy. How long will it take.???
I've got a 95 RS125 (honda) swingarm I would sell you if you are interested. The chain is on the left (correct?) side so you won't be forced into using the Aprilia bottom end. It needs some welding and then machining where the rear wheel came loose and caused some damage around the axel area.
PM me if you are interested.

Its all a puzzell, three FZR shocks, rockers and swingarms and every thing is different.......
Well it's good to see Yamaha obviously were doing some intensive R&D race development on the FZR250 hence all the changes. Probably find the FZR250SP RR R RRR had the adjustable pivot height required for one of the setups.
. . . .either that or some contractor was off loading some longer shocks cheap enough to make it worth changing the linkages.
Don't you look at my accountant.
He's the only one I've got.
Teezee, can we please see a copy of your dyno run.
You built this up for weeks, claimed "it worked", then nothing.
HEY I have a question regarding cut springs, if making the end of the spring perfectly flat is not your idea of fun. Would a turned bit of ally, with a thread cut in that was the same pitch as the springs coils be feasible ?
I ask because I'm probably going to be cutting some springs and can't be fucked dicking around, finishing the ends, when I could use the same threaded bit of ally after every trial cut..
Catch my drift ?
Looks like a really good idea, two things,
I think the length of spring wound onto the alloy plug would be inactive and have to be counted as a cutoff piece and the full length of the plug would have to be counted as preload spacer.
But it looks like a good idea, we might try it ourselves.
