The hoca 70cc kit with one base gasket, stock crank I assume. And actually I can see the edge of the top ring at bdc so its more like 3mm exposed

I'm assuming this is why it seems to be getting weaker each day ,I have put over 400miles on it lik it is now and it certainly don't have the power it had at first and It has never ,hit the pipe, I kinda like thought that was odd as well

The rod has ....yp 4O.... stamped on it. Is that stock? Also the old jug and new measure the same height 64mm. I just don't get it ,to mak my piston flush with th xhaus port I will need 3mm of spacing ,but that would kill my compression.

I definitely have to buy a new crank as the big end has a gap of 1mm, I eventually want to go to a 54mm bore but iI want to buy a crank now to run with h the kit I have any suggestions? Sorce/ price for a good crank?

No I haven't checked squish and the deck hight is 1.3 mm or so it looks good

Compression is around 170psi is that good? And it does get on the pipe its just really weak when it hits,not sure why,maybe my exhaust? Tecnigas
