Hello to all members,been a long ti,e since I've posted anything. I currently have an Ultra with the 96 stage1. Im looking at purchasing a pull tent trailer and always ride 2 up.
Apparently it wont have enough power for this application. I was told to upgrade to a 110, I have no idea about any of this stuff other than what i read. Id love to get some input and also the most cost effective way to get this done with the most reliability.
Thanks in advance
What year is the Ultra? Final drive changed/improved in 09 when the MoCo changed the rear wheel pulley from 66T to 68T. Both are geared to tall IMHO but '09 and later got better.
Going to 110" is not necessary, again JMHO, to meet your goal. There are a couple of ways to achieve your goal much cheaper.
1. A 31T trans pulley and a good torque cam like the SE255, fuel management like TTS Mastertune with a good tune and maybe an exhaust change depending on what you are currently running should do the trick and will be much cheaper.
2. Bore to 103", SE255 cams, fuel management, tune and maybe exhaust. You could always add the 31T trans pulley if more grunt was necessary.
You could start with cams, fuel management, tune and maybe exhaust; if that gets what you want, you're done. If not you have the option of the 31T trans pulley or boring to 103" depending on cost, etc. If one or the other doesn't achieve your goal, add which ever upgrade you passed on, in other words do both if necessary but one before the other.
To build a 110" motor, your cases have to be bored for the larger cylinder spigot which means the top end and the lower unit have to be removed. Once you have gone that far, I would have the crank trued, balanced and welded to stand up to the added load of the larger displacement motor. A very expensive way to go and to take full advantage of the increased displacement, one should seriously consider head work and cams.
Going the 110" route is not necessary to achieve your goal; someone is trying to sell you something you don' t need.:58:
