I don't think you are clear as to what you did? did you open the cams or are you talking about the push rods? I have not done so, but from what I can remember from other write up there is a difference in the lengths of the push rods on the 1700 engine rear cylinder vs the 1600 engine. Also I'm sure that I heard mention that the picture in the service manual is wrong about the placement of the push rods. Sorry I can't be of more help, I'm sure someone will get on here and be able to point you in the right direction.
here are links to service manual, for the 1600 you just need the manual, for the 1700 you need both manual and the supplement

J know that the pushroads in 1700 are diferent that in 1600. One is longer. Yamaha sads that longer pushroad in 1700 is the same like in 1600. Its not true... In 1600 every one are longer...
I open crank case and put out everything.
I found this http://roadstarclinic.com/content/view/211/104/1/2/ but when I make every steps like in this article in cylinders is no compresion at oll... I thont understand why... Is in 1600 are diferent cams than in 1700/
Is there any posibility to damage rear cylinder camshaft? Is it made by one pice of still? |

Sorry, but I can't really be of much help on the internals of the engine, never got into that area, just what I read on other posts. I'm more proficient with carbs and electrical to some extent. I'm sure someone will be able to help though. give it a bit, most are probably working now.

It sounds like your pushrods are crossed. The lifters are inboard and outboard, but I don't remember which one goes to the intake and which to the exhaust.
I would have to consult the service manual to tell you, and I am not home.

The picture on Page 5-15 shows the incorrect placement of the rods on the front cylinder; they should be reversed. The pictures on Page 5-25 are correct.
The intake pushrods go to the front lifters; the exhaust pushrods go to the back lifters.

Do you mean rear cam shaft? If you had to replace lifters it's avery good chance the cams need to be replaced.  |
