Hulign Posted August 6, 2011 Share #1 Posted August 6, 2011 Just want to confirm before I start investing money in this project. I want to get Vmax gearing in my RSV and the Vmax final drives are too damned costly. Found a few FJR setups that are far more reasonable. Nice thing is they also don't have the shock stud to worry about. Can anyone confirm the FJR final drive will work? Thanks for any and all info!!

dingy Posted August 6, 2011 Share #2 Posted August 6, 2011 I have a final drive from an FJR1300 on my 83 bike. The one issue I encountered, and was helped with here, is the spacer 'bushing' did not come with the rear end. Not realizing I was missing it, when I bolted it up and torqued rear axle the assembly bound up. Go to partshark.com 2004 year FJR1300 tab, Driveshaft Tab. Look at P/N 32 callout. It is shown as dashed between #4 & #5. It is shown with a call out # at the top of the view. Very important piece that is 'loose' need to make sure you have one when you put it together. You are going to have to have it machined for the pickup that mounts in it. You can see the boss on the attached picture. I think pegscrapper was doing this, maybe Dano also. Otherwise it is an exact fit for a VMax rear end. Gary Link to comment Share on other sites More sharing options...
flb_78 Posted August 7, 2011 Share #3 Posted August 7, 2011 Do you happen to know what size the hole needs to be for the speed sensor? Link to comment Share on other sites More sharing options...
dingy Posted August 8, 2011 Share #4 Posted August 8, 2011 I don't know. One of the 2nd genners would possibly know. Don't have one on the 1st gens. Gary Link to comment Share on other sites More sharing options...
Grisolm1 Posted August 8, 2011 Share #5 Posted August 8, 2011 Snaged an fjr final drive for $70 with shipping. Pretty sure it has the spacer but will check against the axle diameter to be sure. Assuming the axle should be a fairly close fit into this hole. Am I right? I'd love to know the hole and bolt hole dimensions as well. Otherwise I'll bring both to a machinist. Winter project.

It should be a 'loose fit' & a cloudy memory estimate of about 3" long with a flange on one end. Gary Link to comment Share on other sites More sharing options...

trebor Posted August 8, 2011 Share #10 Posted August 8, 2011 Sorry, I missed the rational on this exchange. What's the purpose of doing it? Link to comment Share on other sites More sharing options...
flb_78 Posted August 8, 2011 Share #11 Posted August 8, 2011 Sorry, I missed the rational on this exchange. What's the purpose of doing it? Lower final drive ratio. Faster acceleration at the expense of some top end loss. Link to comment Share on other sites More sharing options...
