Thank you Frits, my engine was piston port/reed induction ( suzuki ) now converted to full crankcase reed - I guess there could be some degree of all three conditions contributing to the current situation ??

It does seem to get worse as the engine gets hotter through the course of a race

Don't you weigh more than your rig?

I think I weigh about the same as my rig and I am hoping to weigh 135% of my new rig.

Hey guys, tz i have been away for a bot how are you going with that cvt setup. Happy to help you where I can. Do you still want to get hold of some cases

Hi Wax



I purchased some new GY6 125/150 CVT parts, because they are pretty cheap here and there are after market parts available for them. The parts come in plain brown box's without any of the naughty words that would define them as illegal for Moto4 (Bucket) racing.

I need an old crank half and reduction box input shaft for their splines. I plan on extending the shafts so they can be run in carrier brgs mounted in the engine plates.

As best as I can figure out the CVT has a range of 3.25:1 to 0.8:1 which is pretty much the same as the GP gear box. So all I would need is a 3:1 primary or final gear reduction ratio.

So the plan is to have on the right hand side of the engine, a 3:1 straight cut reduction gear set to a cross shaft to the front CVT sheave mounted on the left side (keeps the rotation direction correct that way).

And the front chain sprocket behind the rear CVT sheave. That should put the front chain sprocket in the right place relative to the swing arm. The front reduction gear set could be lubed between races with a squirt of chain grease, life expectance does not have to be great.

If you can find an old crank half and reduction box input shaft for a GY6 125-150 I would be very greatful.

Can you define 'competition part'? I guess anyone can put it on his street bike and go shopping... But yes, it is primarily meant to win races. So what is decisive? The text on the box?

I can (The MNZ can't you grammar so it doesn't matter LOL)
but It maters not its a bit iffy for me even if it as inside the rules (which by the wording, oh bugger this other people can argue it )
I are going a different path anyway.

Did you happen to see my question about the disk vale RSW VS RSA

it probably got lost amongst the hundred others i annoy you with (sorry)

I had a look through the RSA125 and RSW125 manuals i was surprised to see the RSA has a much larger o ring on the disk valve cover.120 vs 126mm
Does this mean that the Rotary valve on the RSA is 4-6mm larger in diameter than the RSW or just the o-ring is out further?
I always assumed they were the same size?

I have found a $40 solution to your power to weight problem. Can post details if anyone interested.

Ok Ill bite ..... but it had better not involve diet and exercise ....

I did. But I did not answer it simply because I don't know it off the top of my head. I haven't been in Holland for some time but my archive still is...

I doubt i came apon the right page (in this link)but pretty sure the shaft you want was there...no crankhalf but i guss Newmanz and co if you can't find SH

Thanks Frits does it sound plausible that the RSA could be bigger (I won't hold you too it you are most patient with me already)
I am not sure you have mentioned where you currently are working? if thats not to intrusive

[wax]

I will see what I can find for you

[TZ350]

Thanks ...

Thanks Husa I remember it now, $8 USD each from memory.

Plausible, yes.
I am working in Beer Country aka Germany and constantly on the phone with Chianti Country. Life is a beach bitch...

[koba]

Chianti

I had to google that.

At least you are in the country with the better beverage.

Yeah but its too cold to drink the beer at the moment over there..............

No such thing!
