Low compression ... Help!!

[ProActive]

6 months ago, i´ve done a top end rebuild had good compression until now the bike only ran about 3 tank on this new top end, and now is starts like on the 10 kick and looks like low compression.

what should be the problem ?? rings ? carb ?

did you do a proper break in on the top end?


have you tested the compression with a guage?

the top end rebuild was made by a professional store that also prepares bikes for competition.

im sure he did the job right its all a matter if you put it together with no leaks and the correct jetting

get a test and check the compression thats the true and only way to get the correct reading

you can get my leak tester in the for sale threads and not have this happen next time...

doing a break in is something that you would have to do yourself, not something the shop does for you.*
