chain conversion help need asap!!!

[07883low]

hi i have a 07 883 low that i am attempting to do a chain conversion on, i have a 520 o-ring chain and i have the v-twin sprockets front part# 19-0384 and rear 19-051. both have a zero offset i believe. my question is i think im going to need spacers, for the front and rear, now i know i can get the rear spacer from vulcan works.net, but where can i get the front spacer, also what measurements do i need. right now i am running a stock 150,but may go to 180 later down the road. thanks.

also the front is a 21 tooth 91-up sprocket, and the rear is a 48 tooth 2000-up. i am mainly concerned with the front sprocket if i need to just get a new one i will cuz it was fairly cheap 25 bucks i think. thanks

Sprockets use a longer front spacer than belt pulleys, but you can't "space" the front. It has to be at a certain place on the splined shaft. It should have offset depending on which way it is installed. If you run it flipped out, you'll need to use a straight edge to see what spacer you need for the rear. 1/16" washers between the sprocket and wheel work great to figure the spacer size.

This is a Renthal 520 front sprocket and Zipper's spacer.

not sure on the front but withan offset front sprocket . i could get you the part # i think istill have the box. to run a 180 tire required a 1/4 in rear sprocket spacer. i also had to have caliper mount machined to center in swing arm hope this helps

hey likemlouder could you get me that part number that would be great. thanks

PBI-281-23 23 tooth PBI trn -sprkt .500 offset it came in a kit i ordered from americanclassic motors also had 4 1/2 16 wheel for the 180. but i am sure you can buy just the sprcket. i am not running oring chain and it runs pretty close to wheel but i am running a dunlop. with a metzler the 1/4 inch would probably work with the oring. hope this helps

hey likemlouder you dont happen to have a pic of your front sprocket?

[Likemlouder]

no sprocket cover is on mine but you can punch in pbi trans sprocket an pull up some offset pictures on ebay. if you can"t find em let me know and i will pull my cover and take you some pics. good luck

likemlouder thanks for the help just one more question how close to the tire does the chain run are the 0-ring chains bigger im just wondering if i should get a bigger offset like .750 or if i would be ok running .500 with the o-ring chain and still get the 180 to fit.
