Inexpensive kits. Come well prepped from the factory. I champfer but it is not really needed for these usually. The rings are well gapped. Slap it on and tune it up. Do a reliable 40ish. Out of the box they do need some work to make them more fun. Take some time and reed adapt it. The dio reed adapter works great to add a v-force block into the mix. Just gotta open up the intake are a bit more and cut a big ol' window in the piston. Hits 50 pretty easily and can ride there all day. I am just rocking a 16sha and it was a blast to ride paired with the 2shoe claw. Hills were easy to get up.
I have since retired the kit due to it breaking off part of the skirt on the kit. But I would have no problems building one of these up on another bike for a cheapo build.

I did what Jonathan Feldman and Mark from Somerville recommended and got the 70cc low comp head. Works great. The kit has been on the bike for about 3 years, 1000 miles. Running Bing 15, 3d printed intake trumpet (no filter), Proma gp pipe, treats stuffed crank (I THOUGHT this kit ruined my stock crank; on disassembly nothing was wrong, but I replaced it anyway) and jammer clutch (with low 1hp gearing, doing wheelies, this kit annihilated my 2 shoe). Regeared, it keeps up with traffic from a stop on a flat. On 30mph speed limit backroads with decent hills it's nice. Never drops below 25mph even on pretty steep hills. 25mph roads it's perfect. Getting about 50mpg.

I loved this kit on my Targa, but swapped out for a Polini. Then, a local guru adapted that same kit to an M48, and now I can love my Batavus too!

I Bought a bike, it was seized. So, why go stock? Put this on, 2 base gaskets, 1 head gasket. With stock gears and head, I got 38mph (PHBG 19mm/Techno Boss). Put on the Lo Comp head, 46mph! And The bearings and seals are original. What can I say but WOW. No I must go, bearings, seals and a Rad Nitto seat have arrived!

This kit rocks on my a35 Tomos, nice power with a 15mm carb and the high comp head. Only issue I had was the spacing, I tried it with the spacer but the piston did not travel all the way up in the cylinder, so I removed it. Then the piston hit the spark plug so I used two head gaskets and sanded them down to get the right squish. Also used some permatex copper spray gasket to get a better seal after sanding. Nice kit for a Tomos if you want a Frankenstein.
Low key awesome
