sleeper06 Posted December 16, 2011 Report Share Posted December 16, 2011 nice run 50/50 race gas premium mix,I would check condition of top end,with 19cc domes and a 4mil comp should be higher or someone lied and its a healthy ported stock stroke bike Quote Link to comment Share on other sites More sharing options...
voodoo69 Posted December 16, 2011 Author Report Share Posted December 16, 2011 how much comp should a motor like that have Quote Link to comment Share on other sites More sharing options...
Keyser Soze Posted December 21, 2011 Report Share Posted December 21, 2011 I had a similar motor and was 165 at sea level off a fresh rebuild. It did have some pretty aggressive port work. Ride it until it wont run anymore then worry. Quote Link to comment Share on other sites More sharing options...

Fastassbanshee96 Posted December 21, 2011 Report Share Posted December 21, 2011 Drop that timing down. That's way to much. Set it at +4. Quote Link to comment Share on other sites More sharing options...

volvo63' Posted December 22, 2011 Report Share Posted December 22, 2011 Drop that timing down. That's way to much. Set it at +4. Yeah, I figured out as of a couple weeks ago what happens when some retard that you buy your bike from sets the timing at +11 degrees.

voodoo69 Posted December 22, 2011 Author Report Share Posted December 22, 2011 i know if the timming is to high in an outbord you get a fat hole in the piston./will i have to change my jetting if i change my timeing Quote Link to comment Share on other sites More sharing options...
rubberneck Posted December 22, 2011 Report Share Posted December 22, 2011 Typically no a timing change wont require rejetting. Its always a good idea to check the plugs after any change though. Just for reference on compression my 4 mil dune ported bike with 19 cc domes kicked 190 psi at sea level on a tested accurate snap on gauge. 160 does seem low but it all depends on porting and squish size Quote Link to comment Share on other sites More sharing options...
voodoo69 Posted December 22, 2011 Author Report Share Posted December 22, 2011 i am at 1900 above sea level her but i do most of my ridding at the beach.so do you thank i should go though the motor Quote Link to comment Share on other sites More sharing options...
