Hi All:
Well, I just got what was supposed to be a high compression slant head cylinder head for my 80 CC HT in the mail. What I got was CLEARLY not for an 80 CC engine with a 47 mm bore. The head I got seems to be a stock head for something with a bore closer to 43 mm.
I know several on this forum have obtained 80 cc slant heads for their engines and reported substantial power increases. And looking at the head I got I could see where this would be the case due to clearly significantly higher compression...if the head fits.
Now, if any of you reading this did get a slant head that fits on the 47 mm bore 80 cc HT please let me know where you got it!!!!. I really want one and the one I did get is wrong. The head is made for a 8 mm studs where as my 80 cc HT has 6 mm studs. This would not really present a problem but the fact that the head was designed to go onto a cylinder with a bore of 43 mm IS a problem. The piston hits the head at TDC of course.
I've searched for ever and found only one vendor that said they had it. But it seems they're not too clear on what they have.
Any help appreciated.
