go with the treats party pack. it's perfectly already setup for ya. the 50cc pack is cheap and mild and should manage 40+

for the ZA's it's not so much the power but the RPM it doesn't love, so you can go with a 70 kit, just gear it up to keep peak RPM lower and limit wear on the bushing crank. oh and definitely flip the clutches to maintain your low-end speed. or just do it anyway because it's a very easy and satisfying upgrade.

Treats Reed Kit with Estoril Pipe and 15 Bing, flip second speed clutch, and gear out to like 20x37

Ken? Is that you?

I will settle for just a link to the kits ya'll mention above, please, just a link to help a brother out.

Thanks, Nick. I was only concerned with the slow acceleration reviews - I live in Denver, so acceleration is key, top end is a factor too, but I really only need 45 or so. Thoughts on that? Anything I can do to keep acceleration?

Thanks for the advice.

this + this +theses (should) = 45 mph, but be reliable and not require a ton of tuning is up to you to determine.

Thanks Mike, I knew I would forget something, hadn't had any coffee yet.

Hi Graham, Thank you for all the advice. Really helpful. Think I will go with this setup as it is a bit of a displacement upgrade but not pushing to the limits. Regarding the nubbin I need to file down, can you elaborate a bit more? Have a photo to show me? Sorry for being so needy, just don't have any context and it will take me half an hour to research or 30 seconds getting it from a pro.

Should I get a new 15mm carb with intake and all that? Is there a kit that has this setup with the carb and other bits? I did order the pucks and gaskets already - thanks to all those who recommended.

Thanks again.

yeah sorry i don't have a picture , when you install the kit, you should remove the rings carefully and dry-fit everything without gaskets, the piston will hit the nub i'm talking about in the cases at BDC. Some ZA's have a nub and some don't, its a weird thing.

research is cool and all but you gotta hit the garage and tune tune tune. if i were you i'd start with just the proma GP pipe and rejet your carb and figure out how all that works. get comfortable taking the carb off and on, adjusting timing, get everything dialed in.

my best advice is hit the garage and work through all the boring stuff first before you spend any money (or get the pipe and do all that other stuff) and get everything running perfecto. The biggest performance gains come from clean, grease and adjust your wheel bearings, get your cables lubed up or replace them, get the chain lubed or replace that, good tires, clean and greased forks, etc.

Well hell, if we’re doing all this, you might want a set of these.

Also, when you remove the clutch cover. Do your best to save the original gasket. End float is very important and changing the gasket can result is a bearing blowing out the side of ur case...if ur not in a position to measure the end float that is....better safe than sorry.

Look into a sealed bearing conversion for that rear wheel...loose bearing snowflakes gave me a tonna problems. Definitely not an urgent deal but still.

Pretty bike!

If you got some that were clean and low miles and had them adjusted up and taken care of they would probably be ok, seems like every time i get a set of snowflakes they are already loose and chewed up with bent axles.

the 11 mm rear axle is considerably weaker than the 12. The one i just built i cleaned up the bearings and got them nice and snug, but you could already tell the axle was bent and the cups/cones weren't sitting quite right, and this is on a very clean and well maintaned 4,000 mile original bike.

Sealed conversion is quick and easy and never have to worry about it blowing up on you. 2 years ago at a rally someone ate shit real bad when a puck snowflake bearing/axle exploded.

Made my day to hear Graham approves of the Airsal 65cc kit. Been worried if I made a good choice. Mine is unboxed and has been sitting on the kitchen table waiting for a little energy/inspiration from its owner to slap it on an e50... or the za50. I'd rather go with the za, but have been indecisive. Think I'll go with the za now that I know I can pepper Graham with questions along the way:))(edited)

For a za50, the mk65 is better. For an E50 airsal 70cc all day, its the perfectly timed puch cylinder.
