Hippo I have a TP107" motor, mikuni carb, and an s&s trans. case with andrews gears I think, PrimoRevera Pro Clutch and primary chain.
I went to the Laughlin River Run last week, right before I had my carb dyno tuned by my local HD shop. It has been slowly leaking from the bottom of my primary and I asked them to check it out while on the dyno. Neadless to say nothing was mentioned about so I took that as there was nothing wrong.
We stayed in Vegas and rode through the desert about a 100 mile trip. Every time we stopped it was leaking pretty heavily from the bottom of the primary towards the front, but there are two square little almost vent looking things(this is also a custom primary cover, made by confederate). Oil all over the rear swingarm and tire. I was nervous, very nervous. I think it's the tranny because of the vibration that soon followed, and the motor oil level seemed fine.
At one of the stops someone suggested that his bike had the mainshaft seal go out and leak profusely from the primary.
Does this sound like mainshaft seal to you? Is this something that I should attempt? I have been trying to get some kind of specs because it is somewhat of an "off the shelf custom" but it has been difficult to say the least.
I am leary of going back to the HD shop because so far the kind service has led to more problems than I care to get into right now, and all I ended up fixing on my own. I have been a wrench but I am new to the total working of a v-twin evo. So far I have researched this has been accomplished by alot of people who are new to the mechanics as well.
Thanks for any help.
