Tomos parmakit cylinder

What’s the scoop in these? Am I gonna be wheelieing and roasting clutches? Is it powerful? Most everything Parma I have seen/touched has whacky port timing. I’ve got my cases already welded up and am wondering what, if anything people think about it. Probably going to be using a 6 p and a parmakit box as well. I’ll most likely run a 14.12 sha because its a tomos and they don’t seem to care too much.

Graham Motzing has experience with them, pretty sure they RIP. Here for results too

Re: Tomos parmakit cylinder

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)

Re: Tomos parmakit cylinder

I expected to need a spacer already, every kit needs to have the deck height and squish set up. I think the point of it is to not have the boost in the piston as it is power ported like a gila and Athena kit. Where’s graham at?

Re: Tomos parmakit cylinder

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.

Re: Tomos parmakit cylinder

did you get a port map of the cylinder??

Re: Tomos parmakit cylinder

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.

Re: Tomos parmakit cylinder

Has anyone ever sucked one of those little sha brass airbox straws into the mouth of the carb before?? Never again will I allow that to happen. I was heat cycling it on the stand and watched that little piece of trash disappear. Lucky for me it got stuck on the reeds and didn’t make into the case...

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.

Re: Tomos parmakit cylinder

Any more photos of that Bimmer in the backround?

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

Re: Tomos parmakit cylinder

It’s the neighbor over at spiral arts. I dunno much about it other than he daily’s it.

Haven’t done a speed run yet, still needs a proper exhaust bracket and the wiring finished up before stretching it’s legs.

Im thinking it will be powerful in the mids and have some decent over rev in second once it gets cooking. I’d be happy with 48 and good wheelie power, would be nice to get a different baffle on it too.

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.

Re: Tomos parmakit cylinder

They’re Parma kit pistons, but this kit is like 8 years old at least. I may have been able to run it with just a fatty gasket and a head with squish cut, but nah. I prefer the metal spacer and this way I was able to use this a55 head I turned for a puch reed kit years ago, but the puch studs weren’t long enough. Seemingly the rippiest tomos kit out of the box. Whitey is going full stupid on an alukit we shall see if it hold together.

Re: Tomos parmakit cylinder

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.

Re: Tomos parmakit cylinder

Mine was a single ringer

Re: Tomos parmakit cylinder

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

Re: Tomos parmakit cylinder

The ring land is strangely enough in the center of the intake port, right inside the boost, but the boost channel is only about 4mm wide. I chamfered it really well and said my prayers to the Virgin Mary.

Re: Tomos parmakit cylinder

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.

That is very possible, the two I worked with were in ahhhh 2016? Maybe 2017, but with out that spacer they were not in any way usable, the piston would hit the head, not like tap, but smack the head, motor just stopped, that as with some random 45mm head too, it’s very likely that. Was just a quality control issue during that era?

Re: Tomos parmakit cylinder

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.
