I have done the same thing on quite a few of those kits and it worked out great.

Dan, the fine details on that cylinder are awesome. The brass stud hole inserts and the decomp plug are a really nice touch.

dremels 'n stuff. my cylinder is ported just like that one. i used some cut off wheels and a tile cutter. then i cleaned it up with a small file and emery cloth.

i didn't cut my piston yet. gonna save that for later. i imagine leaving it un-cut for now will help keep it cool during break in. my imagination is usually pretty good.

line it up with the piston at BDC

I mean the decamp hole in the cylinder, but that looks super good too.

That head decomp plug! A++

looks cool, but starting without a decomp is bullshit sometimes. like if your belt or starter shoes are a little wet, or if either are just worn out.

@Dan ott

Nice work!

Have you coated the squish band? With what? Ceramic? (edited)

No ceramic...just dremeled and buffed out...I wish I had a lathe :)

I do like the flexible wet sanding paper from 3M though

if you knife-edge the bridges

don*t they become hotspots?

i have seen pistons drilled just

to lube the bridge, especially

exhaust bridge

On the hobbit variant after matching the top transfers there isn't match space left for the gasket about 2-3mm. Anyone run into this? What can I do to minimize airleaks? I'm just not sure if it would hold up or not

jesus christ, clean up your tooling though.

My metra ^ is hitting about 11.5 +

But my tach is going wacko when I go higher....so I'm not sure...h95 slow climbed up top to 63 before I had to slow down...if I shorten the header I should get more rpm

On my track bike I did some transfer porting (enlarging and kife edging bridges), ex raised to 180* and the aux ports widened to like 1/3 the way up the side transfers, stock decompless head milled to match Puch Gila squish at 1mm, HPI mini, stock length big muff, geared 14x37 was doing just shy of 12k.

revving great, but the power just wasn't really where you'd want it for a dual variated bike with all that transmission in the way. mellowed out the port timing a few degrees and increased compression by removing a base gasket and I'm getting a lot more usable power without having to have wacky clutch springs.
