    Default Dyna belt to chain conversion questions?

    Who has done it? What gearing did you use? I have had a hard time finding consistent answers for what I thought is a relatively common conversion.
    Trying to find the correct offset tranny sprocket for an '04 Dyna, all stock driveline except the rear wheel is from a '99 Dyna so it has a different size bearing boss.

    One company makes it super easy. Zipper performance. It's a little pricier but way easier than screwing it up and buying the wrong sprockets

    Yeah I haven't called them yet. I though for sure PBI would help me out with the exact specs I need but the guy I talked to didn't or wouldn't disclose exactly what opffsets I need
    I thought that being a stock drivetrain they would help me out. Ill have to post up what I find.

    +1 for Zippers. I know of four different guys with those kits on their bikes (2 Dynas, one with a 120R in it, the other with a hopped up 110, and two hot rodded Sportsters) and they are great. Easy to put on from what they all told me.

    They don't offer what I need. They only have kits for 6 speed tranny.
    I have a 5 speed and a '99 rear wheel. I need to find out what offset sprockets I need. I have all the support,I era but can't seem to find specs on what offsets I will need.
    Also looking for first hand experience with what ratios work best?

    24-51 should be as close to stock as possible. Look into "softail wide tire chain conversion kit" on eBay etc...

    Got this all sorted out for my TC ('99-'05) Dyna project. Once again I have the stock transmission, stock swing arm, 150 width rear tire on a '99 rim. The '99 and earlier rims have a different bearing boss size(smaller) than the 2000 to 2005. Here is what you will need to convert a '99-'05 stock Dyna to chain drive

    PBI .500" offset front sprocket. Drag specialties part 1212-0137 (23T) other tooth counts are available.

    Flat (zero offset) rear sprocket. Drag specialties number for PBI brand DS-325149 (51T). This part number allows you to flip the sprocket to fit either size bearing boss! I went with a Sprocket Specialsts aluminum rear 51T, part number 906-51. They can make most any size you want for this in 530 chain size.

    106 link chain pick your own flavor here. I used drag part 1222-0258. This is 110 links and I cut it down to 106.

    In the process of figuring this out I originally bought a PBI dished rear sprocket drag part DS-325144. This provided me with too much offset in the rear. However if I had a .750 offset trans sprocket this would have worked and allowed me to run a wider tire. So you would need front sprocket number PBI-281-23 and the previously mentioned rear sprocket for the '99 and earlier wheel.
