Anybody have a recommendation for a good place to get a chain? I'll probably get an xring. What length are they? 15/38 gearing seems fine to me. Thanks -D

If you are changing the chain, you most likely need sprockets too. (unless it was age and rust that killed your chain)
Many in the group are running a 15 / 40 or 41. Still good for 115mph.

Cheers, Phil

Thx. I liked the gearing and assumed it was stock until I realized I was almost red lining at 85 mph. I must have a bigger rear or speedo is off. Will check, it seemed to good to be true, i.e. totally usable in town!

Sure enough, 38T rear. What rpm are you guys running at 80-85mph? I'd redline it for sure From to pull 100.

you may have a 14t in front.
With sprockets, its advisable to not run even number in front and back. The inside/outside plates will always fall in the same place, and wear your sprocket prematurely.

Cheers, Phil

I did get up to 95 and was not redlined. Does rap out early though for a pseudo race bike. Even a 750 twin.

Im running 15/38 sprockets on my Paso , and spent most of the time in 5th gear , and wont even get close to redline at max speed of about 210 km/h ( on an Italian speedo ... so who would really know :D ) , in fact I cant see the point in revving it much past 7500rpm as it fall flat on its face about there . :)

I got this front sprocket and it's not the same as my old one which is totally gone. Notably, it's got a shoulder on one side and is dished on the other. The old sprocket is flat on one side and shoulder on the other.

I can't tell if the old one (I just bought the bike) is stock, as the sprockets are each SEVERELY warn on opposite sides, so it was obviously cross chained. Just curios if anyone recognizes this sprocket. It also has a much narrower grip or spline depth, so less of the sprocket contacts the spline and it would likely wear faster.

Thanks fellahs -Dave

That sprocket is for a 750 Paso not the Sport.
If your drive shaft has the fine splines the sprocket is the same for the SS, Monster, 851, 888

If you have the large spline driveshaft you`ll need a deep dished sprocket - just take a look at the parts catalogue.

Which year Sport? The early ones didn't have the spacer on the right hand side of the engine between the frame, so they needed a bit more offset. That sprocket might be correct. Later models shifted the engine to the left by a bit, to get a better chain line. Your best bet with a Sport, is to get a laser pointer, square up the wheel in the swing arm, and use the laser to determine which is the correct sprocket to use. Which part number is the sprocket you have in your hand? I might need one of those some day? That looks about what I ended up with mine, but I went a completely different route to get there.

Cheers,
Phil
