RE: Ultima 107" motor on a 90 model Bagger
No I did not have to replace the petcock. what model bike do you have . I dont know what year the Moco started putting vacuum petcocks on the bikes. My 99 roadglide has one but my 1990 eglide does not. There are vacuum ports on the Mikuni that came with your motor. You can hook a vac line to the petcock which will open it when you start to crank. Thats the only thing I can think of unless the screen in the tank is completely stopped up.

97 roadking with 87K. Relpaced my perfectly running evo since my last rebuild at 61K. I needed more power. Yes I did spot a vacume port on the carb, when I get home today I will hook it to the vaccume port on the back side of the petcock..I finished putting the motor in late last night and turned it over a few times to check oil pressure before starting and no fuel..I will solve that problem tonight and hopefully wake the neighborhood :-)

RE: Ultima 107" motor on a 90 model Bagger
I had the pingle petcock already on a 95 softail so never had a vacuum petcock. Have about 2K on my 127 so far and just love it. Runs better every day although the top cover was loose on the mikuni causing a vacuum leak and the washer was missing under the jet needle after I fixed these problems it ran so much better although I did have to go down to the 175 on the main jet as it was too rich with the 185 and crapping out after 4500.

Beast,
did you ever change the pushrods and if so, did it quite down the top end noise? Just curious. Mine has nearly 4000 miles on the engine and a little over a 1000 on the 6 speed. all is well with both. like you said, runs better everyday.
Goat have you fired the 113 lately ? still snowing up there ? we have had a couple days this week in the low 70's. had to work but was able to ride to work...
Iron rider, i did the same thing. I had about 10,000 miles on my evo after i did a top end. heads, jugs, cam, etc. just wasn't enough.
its never enough........its a diease i tell you, its a diease !

Yes changed the pushrods and lifters to V thunder. Still noisy at idle but these are the high bleed rate lifters and after about 1500 rpm they are quiet plus they seem to have improved the power. Couldn't see anything wrong with the lifters I took out as I was concerned about failure. Because these lifter blocks are so high the fast times pushrods still can't be changed out easily. The Ultima pushrods are 3/8" and the Vthunder are 7/16 so quite a bit stronger.

About a month ago purchased a '90 Ultra frame w/127 in it. Have not had oportunity to ride it yet, Wi., started it up a couple of times, sounds mean with 2/1 Rhineharts. Has less than 1,500 miles since frame up build. In the process of putting 1 1/2 t bars on, can hardley wait.

RE: Ultima 107" motor on a 90 model Bagger
Hey Paco,
I fired it up a week ago. Took a little bit as it was only 30 degrees. Warmed the motor up to roughly 150 degrees and put it back to sleep. Got another 5 inches of snowlast night. I am tired of this sh*t. lmao.
Have good one!!
