The cheater MX85 argument. I might be changing my mind.

Cool as I would happy to take them off if they ban the chassis

At this stage as far as I am aware they are only Banning " 250GP bike Frames"

[goose8]

RS wheels are out as well I believe.

What about I use mb frame rs wheels they use rs frame mb wheels that sound pretty even

Really? That seems stupid. Why are some competition frames to be allowed, and not others?

[speedpro]

If they don't up the capacity limit to 200cc Rich is going to have to get a new chassis and engine.

Exactly. Thats why I have a new engine. Be gone FXR hello ..........


I think that might be a dig at me Drew. But i sold my 250 gp frame to go prodie 250 NSR.

Ya right Drew it would be like allowing some to use competition engines...............

But yes it was (not meant to be mean) jibe /Banter

I think Harley frames are out too...

I'd quite happily ditch my RS frame, having briefly ridden a GPR chassised bike they are clearly superior. If you all want to set me on the straight & narrow please have a whip around to pay Scott to build me one, but don't tell me what it costs I might get embarrassed at your generosity. Thanks again. Or if you decide not to, you're a bunch of miserable winkers.

Because I'm such a good sort, I will give you a donation towards your new chassis AND will even take that burdensome RS chassis off your hands at the same time.

[jasonu]

So Dave, did you change your mind or what????

[F5 Dave]

Well it cost me $300 cw tank suspension sw fairing etc so I'd want to get at least some of that back.

Nice of you to offer, but 2mm clearance is probably getting a bit on the loose side. A nice brand new crank would likely be of more interest. There has been a little interest expressed in a run of offset big end pins. It's getting tempting to check out current costs for say a run of 5. Throw in a (legal)rod kit and a bit of crank machining and it could still end up being quite expensive but you save by using cheap KT100 pistons and being able to step up in .05mm steps extending the life of each cylinder.

Offset gudgeon are you meaning crankpins?

Did you check the scooter ones i posted a while back against the STD mb/H100

Actually the T5 eccentric pin looks like it could work with limited mods as its only 2mm short

The width at the big end is workable? with thinner thrust washers

Rod the right length but the little end is to big, so bugger.

Would a 52mm bore + oversizes and a de stroke of 2mm work?

not for me..........
But I have a 24m big end.lol
No one's tried the pin as far as I am aware Looking at the vespa crank it may not be long enough
(which I put in post or the previous time mentioned them)
from memory the lambi rod is about 15mm wide.
Been a while. but at the time lambi als had these pins available i don think I could find much further information on the sizes and length of the std lambi pin.
this vespa is 2mm short whch may or may not be an issue............

[F5 Dave]

Have to get lucky with widths to suit. And only $100US, a snip, might've well buy a few to try.
