The crotch groove helps alot… you should know that… or… not…
Did you check to make sure that your right crank is on the right side and let crank is on the left side(when the seat is facing the correct direction.) That could be your problem.
They are 127mm cranks.

Yes, the cranks are on the correct side, which is the problem. Being a two-wheeler, I’m pedalling backwards 99% of the time. It’s quicker and easier to turn the seat around than strip it all down to get the wheel out to turn that around.

You could simply pull the cranks and swap those - but it seems you already have a solution…
Oooh! I like the graphics! it’s kinda like mine, the paint was starting to fade, so I found one of the greatest inventions on earth… the sharpie pens! this is the results:

LOL.
I just finished up some of the customization on my 24" Nimbus MUNI. Still have a couple of items I am working on but thought I would post up some pics of how it looks now.
Orange/Black checkerboard fade paint
Orange logo on Venture Cranks
I have heard some bashing about the Unicycle.com head badge, but I think it is a pretty neat design, just had to cover up the putrid bronze color.
That is a Nimbus seat clamp with the lettering filled in and color matched (the standard orange doesn’t match at all)

Now I just have to learn to ride it
Wow! this uni is awsome, you did a really good job. Now it looks like a Bedford uni, Haha. I like the way you painted the frame, it looks really nice.
I just put the Nimbus seat from my other uni on my Nimbus II, and I really like the look. Oh, and I also put a 114mm crank on(the other one is 89mm).
Totally custom.
Well… its not finished yet, but I’ve begun to break it in lol. Here’s my custom nimbus as it stands right now:
Custom powdercoated nimbus frame (the color is metallic and much more intense than it appears in this pic)
Nimbus isis hub, black spokes, nimbus muni rim, green nips to match the frame (just finished building it)
Kh street saddle (I think I’ll go back to the nimbus street saddle, it’s the most comfortable saddle I’ve used)
Venture 152’s
Clear green pc’s to come, I was gonna custom drill the rim, that’s one of the reasons I went w/ the nimbus, but I decided to keep the extra strength and see how it holds up. I laced the wheel cross 4 instead of the usual 3, still a heck of a lot lighter than my 29er! Mostly laced it that way for the fun of it, built it up and after I brought most of the spokes up close to full tension and stressed them a bit, I realized I had not boxed the valve stem correctly 
(I carefully laced it up, and the spokes seemed like they were too long, so I started to pull it apart, after double checking the spoke length, I rebuilt the wheel but I kinda rushed it, hence my error) oh well, it’s gonna stay like that now! 
Crap, looks like the pics did’nt work, I’ll have to try that again…
sounds like its going to look good tho would love to see it.
My pink uni is soon going have Painted orange spokes, Painted Green spoke nipples and a flro yellow rim. well its all going to be flro its going to look soo cool
How are you going to paint your poke nipples? Even a light coat of spray paint would change the thickness enough so that a spoke wrench won’t fit.
I’ll mask the rim and spokes out then go from there it’ll be a mis but i think i’ll pull it off lol. I have all the plans for it in my head lol.
But i’ll mask the rim and spoke nipples off paint the spokes roughly (let it dry) mask the spokes of paint the spoke nipples roughly (let it dry) mask it off and then paint the rim. It’s going to take at least 4 days but i have 2 other unis i can use in that time lol
ok, here it goes again, i’ve gotten the green pc’s, but they don’t quite match, and i didn’t have time to get new pics. here are the ones i attempted to post before:
-sorry for the low quality, my camera was dead so i took the pictures w, my phone.
the color is a very bright metallic green powdercoat
nice green i use to have a limeish green on my nimbus 2 but its now white and it’s only half made up (need cranks, Pedals, seat post) lol in time.
Your uni looks nice dude
I want to ride it…
lol so do i…
What are those cranks like by the way?
Thanks guys! It’s holding up well so far, and I added some green twisted pc’s.
So far I like the nimbus venture cranks exept the stupid logo, lol. The shape reminds me of the tensiles, but I’m not sure if they’re quite as strong. I’ll beat 'em hard and see how they hold up. I think they could be great trials cranks if they made a 140.
They’d be perfect if they had a little more q
cheers i’m thinking of getting some for my freestyle or trials
