thanks Marv - very useful :2thumbs:
so with yours the chain wouldn't clear the tyre without the 1/4" offset in the rear sprocket? I'm a bit confused too about the front sprocket having a 1/2" offset when it supposed to be zero offset - that obviously makes a big difference - did you need a 1/2" offset with your front sprocket?
I might go with a smaller front sprocket than a 25 and match the rear to keep the ratio as close to what I have now as I can - I do accept there might some grinding involved though and I'm not too bothered about that
you need some offset on the front. the zero with the 1/2 built in was the tightest i could find. cant go wider or your hitting the ramp door.
the 1/4 offset on the rear is needed to center the chain. otherwise it rides to one side of the sprocket. no problem with the tire.
i have the 50 tooth hhi now, they recommended the 25 front, but the bike is apart so cant look to see. but i think its either 1/4" dished rear sprocket or HHI with a spacer centered the chain with the 277-25.
25/50 is good. its lower geared then stock. any lower and you'll pay at high speeds.
even cut like this it still rubbed the cover
here's the final hack on the cover
drilled a hole and tapped a bolt into the trans door. used a spacer on the bolt from cover to trans to keep it from flexing.
here's a pic comparing BD's cover to an aftermarket cover (which is the constant for RSD)
"OLD" = bd'S COVER
the difference in the lower left bolt is why bakers chain conversion doesnt work :down:
