All

thats what i was just thinking as well i just didn't have a new one to compare it too, i might buy that cam off you do you have pics?

no it had upwards of 160 psi with the auto decompressor off. the cylinder head is new, are they not cut from factory? i just lapped in the new ones and they have a nice seal and increased my compression.yea i usually never have to change the exhaust valves but i bought the bike blown up, i am almost thinking...

i have done that, also when i start it with out the exhaust on no codes come up on the mil light, everything works and the bike runs like new with the exhaust off and the timing retarded one tooth, did just notice i need a new head gasket as mine is causing bubble in the rad that wouldn't cause...

i was hoping not to do that, already spent too much money on this. can anyone tell me why the bike will run with the exhaust off but not with it on? i just put new exhaust valves in it this morning it made the compression a bit better but nothing has changed with starting also when i have it...

no way i wish mine wasn't so stubborn, i have all brand new electrical parts i spent over 3000 in parts and nothings changed since the day i got it, only things i haven't done yet i could try is new valves or messing with the tips, still not sure where the idle knob should be iv tried all different...

what could happening with it running with no exhaust? iv been tinkering with this thing for far to long now, everything is pretty much new except bottom end, i have new valves i might put in to eliminate a leak, i re timed it which i feel is retarded one tooth and it runs clean through the rams with no...

as long as it has good tension on the chain i think it shouldn't be much of a problem, but i might buy one just to see. i have replaced almost everything in the top end iv done leak down tests and everything. I'm gonna check everything all over again

yea i never forget the basics of what makes an engine start/ run, iv taken the fuel injector out and kicked it while it was connected to the tank and it seemed to spray a good amount of fuel so i assumed it was good, got good spark, and i would assume I'm getting air, i have 120 psi compression...

i have replaced piston rings, jug, cylinder head, did a leak down test and all valves are in spec when i time it. iv also replaced spark plug wiring harness, condenser, rectifier, alternator and ckps, iv checked the crank for and damage but it's solid. iv only had the bike start a few times with the header off and i...

ill check the timing again tmr and post pics, everything seems to be good the lobes facing towards the back and how would i know if the cam gear spun?

In need of some help does anyone have any advice?

i have an update if anyone else has any info feel free to let me know what you think. got my bike started today but could only get it started with the exhaust off won't idle and runs shitty through rpm also won't start unless throttle is about half way could it be tps? fuel pump weak or injector?

yea, i have the special tool that hooks up to the harness and hooks up to a battery that has the ecm selector switch and fuel pump, the fuel pump works, just not as good as flow as what the manual says so i have a new pump on it wayy with a new injector. I'm leaning more towards the...
