compression

[sldbanshee]

my compression is at 105 in each cylinder...im not sure if thats low or not but until i warm it up it will only start by pulling it around someone please hellp

[Bansh-eman]

sounds like your ready to rebuild the top end...

[5150banshee]

time for a top end,stock is between 125 and 135.

[sldbanshee]

so that would be why it wont start right?? correct

[Bansh-eman]

yup, when your low on compression its hard to start them. and you ruled out spark casue it runs when you pull it.

[sldbanshee]

yea the compression is at 105 in both but when i do bum start it the spark acts alittle fishy too

What is your elevation where you ride?

105 is real low at or near sea level...if you're at 5000 to 8000 feet....you have another problem.

yea im at sea level but beofre this happened i was having spark problems and i ended up smoking the crank...i just hope i can get it solved cause the spark still acts alittle weird

Can you explain exactly what you mean by spark acting weird???

when it first starts up only the right side will fire or the left until it warms up..i think thats another reason why its so hard to start...but the compression is low too and it was running lean but i fixed that problem

What compression tester gauge did you use? Did you warm the bike first, hold throttle wide open, take both plugs out and kick it over 10 times?

 

I am more inclined to think you have a hard start issue because of a spark problem if you know you have had a spark problem already.

m not sure the brand of teser but i screwed i in the head and kicked it ten times...and i was riding it around before that so yes it was warmed up....what do you think the spark problem could be

[Bansh-eman]

if you switch caps does the problem follow the cap?

You have to kick it until it stops going up...often 15 to 20 kicks or more.

 

As said, swap coil leads....see if it follows that lead.
