Just got one, now looking at a zocchi bike

Good evening,
I just got a chinese pocket bike. Runs not too bad (hard to start though) and good fun.
I'm looking at a 80cc zocchi bike. I suppose it is a few years old as I can't find much online.
Anybody has had one of those?
Looking forward to hearing some more!
Cheers
David

Somehow I can't post in other parts of the forum. Perhaps as I am new, do I need to do anything to further activate my account?
Cheers

I'd like to know more about the zocchi bike. Web address? I think you need to post one more time. Welcome to the forum btw!

Re: Just got one, now looking at a zocchi bike

You need 3 posts, I have Zocchi clutch parts for my Italian Polini, never heard an 80cc Zocchi motorcycle, but there is always a first time. Is it a dirt bike, 4 stroke, 2 stroke etc. Photos have to be 1/2Meg. ( 512Kb. or less times 5 per post or thread. Avatar 90Kb. or less is in the Control Panel Menu-Edit Avatar. Photos would be a great help.

Re: Just got one, now looking at a zocchi bike

Hi, thanks for the replies... well it is not a zocchi, it's a polini. I picked it up last night.
I will try to post a picture, looks great, needs a bit of work, hasn't been started in a few years and pull cord is broken.
but fairings and everything else looks great!

Re: Just got one, now looking at a zocchi bike

likely not 80cc, I will start taking it apart and cleaning everything to get it going good after a business trip in the next few weeks. Should be fun project and bike after!
It definitely looks like it is very well engineered!

That is a GRC RSR. Great bike, I have one. It's actually my avatar pic. It has a polini motor. The largest motor they came with is a 50cc but they are fast! Take off the fairing and show a pic of the motor.

Re: Just got one, now looking at a zocchi bike

Great! Thanks for clarifying what it is. Looking forward to getting it going but I want to make sure the coolant system works and clean everything first, no point getting it going ''half a..''
I will post a pic of the motor once I have a few minutes to get at it and the fairing is out.
Cheers

Re: Just got one, now looking at a zocchi bike

Yea, you can't go half a.. These engines like you can with the cags. Luckily the water pump is exterior to the crank case and so it is much easier to see if it's running correctly. The belt for it should be connected to the pinion gear. Fill the bottle then with your hand spin the back wheel, that will drain the bottle. Keep doing that until the bottle stays half full. If you don't find leaks and you have to full the bottle about 3-5 times you should be set. You shouldn't have issues with leaking into the cyld but keep a good eye on the bottom of the cyld for leaks.

Re: Just got one, now looking at a zocchi bike

Thanks for the pointers on the coolant. I will flush it nicely and find the appropriate stuff to put in there. I guess car coolant is best but I will do a search here I suppose for right info. Can't wait to give that bike a try!

Re: Just got one, now looking at a zocchi bike

I know this is going to make me Cry, lol, how much did you pay?? My avatar is a GRC GP1, 2006, love it, all alum custom frame. Polini engines and DM, GRC frames, my favorite. I like the external water pump driven off a pulley with an O ring belt behind the pinion sprocket and pump mounted off the clutch housing. Some Polini's like my 910 Carena have a frame mounted pump and driven off a O ring pulley behind the rear drive sprocket, I made my own bracket and mounted the pump up front, on all my Euro water cooled bikes. A Polini piston ring is around $60 to $90 for chrome USD, 36 or 40mm Polini cyld about $400. Online in the USA, a lot of us get parts from midsouthminimoto on the .com Stoney has Blata, Polini, GRC & many another parts.

It depends on if you plan on racing car coolant isn't a good idea because if it drips it's really slippery on the track.

Thanks, probably won't be racing just yet. I don't have the full leathers so I will see what I do. I have to ge I g and ride it a bit first. if I put a mix of coolant, it's the pink OAT stuff that's best?

Re: Just got one, now looking at a zocchi bike

I use Peak anti freeze at 60 water, 40 coolant, don't have any tracks to race on. That's why they call me The Outlaw, lol.

Re: Just got one, now looking at a zocchi bike

Thanks!

So my friend got the bike running (while I'm on business trip), coolant was pretty gross and he cleaned everything up, it apparently fired up with only two pulls on the crank!

I heard it run and it sounds great, it's running quite good.

He mentioned that the clutch would only engage at quite high RPM, I suppose they can be adjusted?

Can't wait to be back and try this thing this weekend!

Re: Just got one, now looking at a zocchi bike

Here are some pictures.
I'm thinking of purchasing a water pump kit, is this the zocchi pump?
And can you identify which polini engine this is?
Sorry for the many questions!
Thanks for the help! (again)

Re: Just got one, now looking at a zocchi bike

Don't get a new water pump kit unless it's leaking. Not sure on the pipe. It looks like the 39cc or proddy engine, but I could be wrong. It is supposed to engage at a relatively high rpm, 7-8000 is average. It feels real high at first but you'll get used to it. But still check the rpms to make sure it isn't too high.

Re: Just got one, now looking at a zocchi bike

I have questions every day, lol. Don't know much about Zocchi stuff, they usually have their name on the pump, my blue alum BZM pump for my BZM W/C cyld/head engine I am building is stamped. If you look at the last phot of the GRC pump, that's a 80mm Polini bell and housing and a 78mm BZM 2 shoe racing clutch. I have a 40mm Polini scratched cyld and good head here that was on my 50cc Banshee Sho clone Polini. The China engines are real close, but junk compared to a Polini. You probably have 12 to 14 hp, Redline is over 13,000 RPMs, all my clutches engage around 8,500 RPMs where all the power starts.
You better hang on to your Go-Nads, remember, your sitting on the rear tire, it wants to wheelie all the time. My Polini 910 Carena now has a 40cc 36mm bore and 39mm stroke Polini 5 port air cooled engine, modified reed stops and custom carbon fiber reeds, have a real 14/14 Dell SHA carb going to replace the China 14mm on it now.

Re: Just got one, now looking at a zocchi bike

Thanks again guys for the help. Not sure I fully understand the 80mm and 78mm ref yet I will have to do a bit more reading. So ERP which engine you think I have? Real 40cc polini? Sounds good about the clutch kray15. That's reassuring. I'm back in town tomorrow for a day so I will give it a quick try and look more into what it has.
And Peak antifreeze, you use the pink stuff (for European cars) or green-yellow?
That's a very clean looking bike - build you have there EPR! Looking great!
Cheers!

Re: Just got one, now looking at a zocchi bike

Oh it's a real polini engine for sure! I just can't tell if it's the 40cc or the 50cc. But I'm pretty positive it's the 40cc. Do you have a tachometer? Honestly I used water for my coolant for a while, mainly because I was too lazy to buy real stuff haha.
