Is there something missing?

[KieranM]

well,
so i was looking at pullstarts for my new bike and i was wondering if there is something missing off the flywheel. I bought it and the lad said that the pullstart casing was missing. There is two threaded holes in the flywheel and i dont know what they are for. I have never worked with these engines before and im unsure about their setup.

Could anyone give me some advice.

Thanks

not 100% but thing there is a clutch that goes in there

or, there are arms that are spring loaded

 

[imSRB]

is it a pullstart engine, becuase if it is then it should have a little metal cup thing that goes in the middle .

I think there are two spring loaded metal arms that are supposed to go in those threaded hols. Like in this picture

exactly what archer said, you need to get a whole new flywheel my friend. They are only like 20 shipped

have you figured out what kind of bike it is? or rather the motor? i just looked at some, but it seems the motor you have is the same one you asked about on ebay. i have no idea which one it is or where to start looking for info

http://www.usapocketbikes.com/mx3-pocketbike/ this looks similar to me, is it the one?

 

[solomon]

yea looks like a 47cc flywheel to me.

mike, i bought it and the lad did not know alot about it so i have no idea. Is there any way of id-ing the engine? i cant find any numbers on it

 

[mike75925]

the easy way is to find a similar bike, and see if it has the same engine. sometimes the engine will have numbers stamped into it like on the gy6 engines. they normally have a 3 letter code QMB or something similar, that tells you the size of the engine. gy6 are fairly recognizable though. did you check out the link in the my previous post? it looks similar and appears to have a rear carbed engine as well. on the site, they sell o.e. and performance parts.

 

[KieranM]

yea thanks for that link useful parts on there. I will go out again in a while and have a look. I have seen pullstarts with pawls in them, would you think one of them is all i need.

[mike75925]

i haven't been into one to give you ins and outs on them, but from what i have seen, it seems that that is the correct pull starter for your engine. being that it comes with the pawl, if it is the right one, it should get you going. there may still be pieces needed, i really couldn't say.

 

[solomon]

I know those engine very well, if you can take some pics of the motor, i can surely get you the right parts.

 

[KieranM]

I will take some better pics of the engine tomorrow, i have a day off so i can get to work on it and fix some of the fairings. My engine is the spit of this one from what i have seen

[solomon]

Yea thats a 47cc engine, beware, those flywheel are VERY hard to pull off! They get stuck and can be a *****. IS the pocket bike a full fairing or half fairing? if its half you probably have a caglarri

 

[solomon]

This is the cheapest http://cgi.ebay.com/NEW-47CC-49CC-MINI-POCKET-BIKE-ATV-QUAD-FLYWHEEL-FW02_W0QQitemZ170450227917QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item27afa012cd

And this one is a bit more but does add alot more HP HERE

 

[mike75925]

according to what i have seen, all you need is the recoil assembly and the bolts to secure it to the engine.

 

[solomon]

I would replace it, looks like the previous owner tried to solder/weld to it.

 

[mike75925]

he definitely should, if when it runs, it vibrates anymore than it should.

 

[solomon]

lol, i would just buy that Racing flywheel, it was the biggest performance on my pocket bike, i had a race carb and that flywheel spun the motor WAY faster.
