Been doing some research. Baker conversion looks pretty good but just got e-mail from woman at Baker and she said 23 tooth countershaft sprocket is the only one that will work.(23-52 for a stock ratio), I would like at least a 24T to gear up somewhat. Even Baker lists other ratios but utilizes rear sprockets to accomplish this. We all know its much easier to change drive sprocket and may not even need to lengthen chain if adjusted for such. She also said they utilize a chain tensioner, ala dirt bike I guess. Does anybody have any first hand knowledge of the Baker conversion? Where am I going wrong? Thanks much Bob T. | ||

I used a 51t for the rear and I cant remember what I used on the front!!! I will try to remember and see what I used tomorrow. I LOVE MY CHAIN | ||

Bill, did you do your conversion with stock Harley parts and do you have any part numbers in case I decide to go that way? What all is needed besides the two sprockets and chain? Is it a 530 size? I'm having some small trouble with the Baker stuff but may still go that route if I can get the right answers. Thanks much, Bob | ||

Also, for anybody out there if speedometer sensor is off mainshaft in trans will this alter readings if ratio is not the same as stock (2.26)? | ||

I used Harley Parts. The front was from a 1991 Sportster and the rear is Big Twin. I screwed up the rear sprocket in that when I got it the hole in the center was too small so I took it to a machine shop and had them cut the hole the same diameter as the pulley that came off. I think the hole in the rear is the same size as the early 80's big twin, I think I ordered the later model one. I also had to use a shim on the countershaft to get the sprocket out to clear stuff. I used a good quality 530 chain with o-rings. For lubrication I am using chain wax as it don't fly off getting everything dirty. I tried conventional chain lube at first but it just went everywhere. I now have almost 20,000km on the setup and the past week or so I have noticed it needs adjustment. I can tell because the chain strikes part of the frame at higher speeds, when its properly adjusted everything is great. As for tension the pivot point for the swingarm is so far from the countershaft I set it very loose when on its stand or a swingarm stand, when weight is put on the bike i get the proper tension. I have not checked the size of the front yet but will do later this evening. I find the gearing is very good as it can still pull up the front in first and second without any effort and on the highway at 100kph/60mph the tach is reading about 3000rpm, at 4000rpm the speed is reading approx 140kph. The engine speed is much lower than the stock S1 Gearing. Of course I have kept all the stock parts just in case I ever want to put a stinking belt back on. | ||

Thanks much Bill, still pondering, will let everybody know my results. Bob | ||

Bob, I am in the Garage right now and just counted the sprockets. 23 on the front from a 1991 Sportster and a 51 rear from a big twin. | ||

I just ordered the Baker kit today. I'm going with the 23/52 sprockets which is the stock ratio. I'll install it early next week, since it won't be in until probably Friday, and this is Laconia Bike week. I'll be heading North to enjoy the Rally, so I won't have the time to put it on until I get back. | ||

Baker makes a 24 tooth sprocket, but the issue is that the diameter of it is too large. I think it interferes with the billet bracket that supports their chain roller. The chain roller mounts behind the two rear bolts that hold the swingarm support bracket (the one that says Buell on it). Or at least that's what it looks like from playing with the parts from the kit and looking at the installation instructions. I have not tried to mount one, however. Al |
