MOPED ARMY

here for results

They can rip but the port timing is crap, you need to make a spacer to run them properly, also the piston that comes with the kit is crap, no boost port, cut your own or get the treats teflon coated piston

in short, not worth it

a lightly ported 44mm Airsal is a much better choice, cheaper, just as fast or faster (edited)

I made some progress today, first start went well. I didn’t time it yet, but with the Parmakit box it seems very responsive, even with single petal reeds and a random 14.12 sha with god knows what jet in it. As I thought it needed a spacer, I used a 1mm spacer with .1 gaskets on each side. I slathered the shit out of it with motoseal as the material added to the transfers is a little questionable.

Shout outs to; smog squad Mike for hooking it up with the bennasar blaster pipe, Kellen for the frame bits and cases/kit and all of our loyal customers that leave their half broken parts for me to foolishly make work again.

Oh yea and I almost forgot, no pics yet!

It’s basically normal a35 cases turned into the nice meaty revival cases and the transfers opened up. I dont think you need to see what a tomos engine looks like. It’s not that exciting.

I’ll update it this thread with some pics of the bike on Monday when it’s all buttoned up.

I did not, I kinda just slapped it on wondering if it would even run. I may pull the head and see what the durations are, but man it’s a fucking tomos, my heart says don’t do the science. I basically only work on tomos at the shop and this is the first one I’ve actually built for myself.

Guess what?

This thing rips! Unported it hits hard and carries the power nicely all the way up to ??? Red spring in 2nd gear may be a little too much with 26x24 gearing. Maybe if I were to get 28x22 it might be in the power band in 1st still when it starts to shift into 2nd, but right now it drops in super nice into the power and of the blaster pipe.

define rips? Whats the top end, my slightly ported Airsal does 50 at just a bit over 10k, 2.5in tires is the only gear change

huh?

i've thrown 3 of them on over the years and never had a single problem with piston or port timing, maybe they had some switcharoo and stuck the wrong piston in them? 2 of them that i built for other people back in the day 2009-11 ish, the one that i have on my bike now was bought used but never run in like 2013 so who knows when its from, but the timing was perfect out of the box, dead the fuck on.

yeah i think maybe what andy is saying is that they went to a shit piston in later years? like a lot of the manufacturers do when they loose their piston supplier or whatever, they just grab whatever fits and you get stuff with gudgeon pins being in the wrong place, timing issues, etc.

the piston that has come with the ones i've bought is two thin 1.5 mm rings and very nice finish.

i'm almost tempted to pull that tomos motor back apart and check, but when i built that thing 3-4 years ago i went over it real careful and checked everything.

hmm, the plot thickens... its been 3 years let me see if i can find photos of the build somewhere

So outside of our shop is a really disorientating intersection. People don’t pay attention at all or even look before rolling o it into traffic and constantly blow a stop sign into the wrong way and get T-boned. I have been collecting the nice fog lamp projectors from the Subaru’s and Volvo’s left over street garbage. I chopped open a sealed beam and folded up the edges all the way around and jb welded the projector in there. Holy hell it has a super solid block of light. I’m so stoked to have an actual beam instead of shitty moped headlight. Pics l8er.

At some point didn't they stop making the Hobbit one too? Maybe around the same time. I vaguely remember s one-time like 2014 I went to buy a puck one and Benji said they were no more. Then they came back, maybe from a different factory and the wrong piston.
