Wanted 16T for 163fml-2

4xflyer · 03-29-2007, 06:54 AM

Anyone have a new or lightly used 16T front sprocket for the 163FML-2 engine that they want to sell or a good source for one?
Thanks!
Gary

Helpful hint; If using 520 chain on a 163FML2 engine, a 15 tooth sprocket will contact the engine cases, some grinding is necessary to fit the sprocket and chain. Probably best to use a 14 and change the rear sprocket to get the ratio you want.

Actually I need a 428 sprocket. The 520 is heavier,bulkier and probably better for power output over 20-25 hp (imo).
I presently have a 15-46 setup and need more cruise speed (at least 50-55 at a reasonable engine speed).
BTW does anyone know if a 428 chain can be used on a 420 rear sprocket?..They are the same pitch but the 420 sprocket is slightly narrower. It looks like you could use a 428 on a 420 but not a 420 chain on a 428 sprocket.
Thanks for the 520 info!

A 428 chain SHOULD ride on a 420 sprocket fine. Like you say its the same pitch, but narrower. But, I have never tried it, so let the buyer beware. My roketa has a 14T front 46T rear and cruises just fine at 50 - 55.

Flyer,
There are probably over 100-200 posts about this topic alone on this site, go through the forums and give them a read, you'll find an abundance of info about these bikes by doing so...

He's also asking if someone has one for sale. I think its a valid inquiry.

I've done the research..just looking for a 16T to use with my 46 or a 14T to use with a 40T. Would prefer the 16-46 though because of possible premature chain block wear!

Thanks

Im sorry, I was refering to front and rear sprocket combinations as several of us have tried many different combos, thought you could get some better info on this by reading some of the older posts.. EJ Cycles sells sprockets for these bikes, you may want to contact him...
