Firing it up for the first time. No luck.

Hey guys, Iím finally finishing my trike. wish I could post some pics but canít figure it out. Keeps telling me the file I too big.
Anyway Iím trying to start it with no luck. Iíve got an Ultima 120. 2.0 thunderfire starter with an X rated battery. Doesnít seem like itís turning over quick enough. It turns over about 1 1/2 times both then stops and the compression release close. Any suggestions appreciated.

Hook a known good battery(even a car battery) up to your battery and see if that helps. If it doesn’t, go right to the engine and the large post on the starter. If connecting it to the battery solves it you have a battery issue, if connecting it to the engine/starter fixes it you have a wiring issue, most likely a bad ground.

Agree with the captain. If starting system is correctly set: good battery, at least 310 CCA , good starter,> 1.75kw , and I prefer to use A HUGE gauge cables / ground(size of my finger) , it should turn fine even after releases pop out.

However, for my 127 I made my compression release hold stronger and longer while cranking:

Disassembled first:



THEN FILED A BIT DEEPER GROOVE ON THE VALVE WHERE THE SPRUNG BALLS HOLD.
The deeper- the stronger. Don,t overdo!
Then assembled with the sprung clamp instead of the cover I had cut off. And instead of the plastic button, just a snap ring.

120Ē ultima.
Ultima battery, ultima starter 1.75kw, ultima release valves that came with the engine, not modified.
Cables marina grade, custom cut and crimped in a store.
I Used 1/0 vs 2/0 gauge cables. They are ~twice as thick as Harley gauge 4.

The battery tested at 13 volts . I am running a long cable to the starter. My battery is mounted at the rear of the trike. The CCA on the battery is over 500. I’ll look at all the grounds and try hooking up a battery with jumper cables.

Yes. Thanks.
Now in your case, with remote location, longer cables, they especially better be thicker.

My BMW m5 had a huge battery, huge CCA, but in the trunk.
The cables were size of my thumb I believe.


I can,t emphasize enough that the size of the cables is one of the most overlooked parts to have a healthy starting system.

And also as far as wiring system, fuck cosmetics. I run my electrics using 1 size bigger wore gauge that typically used. Even the most remote appliances have no less than 16.

I think the cables might be my issue. Also my ground is probably no in the best spot. Is the tranny the best place for the ground?
My positive cable is probably 5 ft long. I have it in mounted in a keg in the back of the trike.

I always use the same location for the ground cable- one of the 2
5/16 starter mounting bolts. It I know a lot of people connect to the frame as it,s also a huge conductor. Some use a couple of grounds ( which increases total crossection of the negative conductor thus reducing resistance= more juice for cranking.

I would have a lot of reservation about remote location of a battery, unless 1) it was seriously oversized and had huge capacity+ CCA) 2) I could use thick cables
In such case the whole system( except the starter) better be bigger..

Next time you want to post a picture, you are going to have to use a program like Photoshop and reduce the image down 50% or so. I made a device to manually hold my rear compression release down while I crank my 127..It's just a piece of stiff wire ran off of the rear motor mount
that holds the rear release down and the bike turns over and cranks easily with the releases held down. I tried to crank her one morning and forgot to use the device, and shattered the starter jack shaft, it exploded.
broke several teeth off of the ring gear and jammed in between the casing. It took hours to cut those teeth out from the casing, and quite an ordeal to install a new ring gear..all this because the compression releases popped up before the engine had a chance to get going.

Guys. Thanks for all the feed back. Sounds like it might be my cables and I may have to relocate my battery. Won’t have a chance to look at this for a few days. I’ll let you know how I make out

just try to connect the battery closer to the starter using short cables. See if it makes difference. Then you will decide what is the next step.
