Lince 200 o-tuning à la mode fastfrog

[eden]

one day its telling me one thing then and next its saying something else. Ive learnt over the years when its happy and when its got the hump and ride it to suite how it feels on a particular day.

Does it bleed for six or seven days every month too?

it's made me bleed several times, it tends to bite when you least expect it ;p

she's a dirty dog!

Enough of this, lets see some more pics and stuff from fastfrog

I'm waiting for new parts to come. 3mm packer, new head, batch of head gaskets...
I need the packer to start the case job. I'll start the slight inclination from the packer cos the case flywheel side transfer is tapered reducing the seal surface. Am I clear??

Back to the o-tuning stuff:

Mark Br. did me a very nice 68 mm cnc head with a 1mm recess. A much more matching head than the one I ordered a bit too fast weeks ago....




with a 3mm base packer piston at TDC is 0,5mm out :

good thread
did you look into other piston choices ?
I am going for an RD350 standard 64.00mm on mine, as they are a good piston, readily availble, and reasonably inexpensive.

i looked at every 67-68mm I could easely find and tune. This one is a bit expensive but forged....

classical issue: no meat to port it well (left transfer right on the pic)...
I'm good for a bit of a welding job...

back to the lth reed.
cut a 1,5 mm packer to secure manifold seal pad.
