help please. hard start banshee and less air pressure in one pipe.

[bansheedemon]

hi guys. im sure rhis has been answered a million times but im stuck. im new to 2 strokes but mechanically inclined. i took the banshee for a ride today. its started fine and i warmed it up and then took it for a quick spin. ran perfect. got on it to clean it out a bit, plus its just plain fun. then i pulled back in the driveway and accidently dropped the clutch and killed it. and then it was hard to start, i had to kick and kick and kick to get it started. then when i finally did the left side pipe didnt seem to have nearly as much ait pressure coming out. it was better when revved a little but not as much as the right side still. i was afraid to get back on it to how it runs. i didnt want to break anything. it supposedly on a fresh rebuild with about 8-12 hours on it. it idles fine once started and doesnt seem to hesitate when you hit the throttle. im running 32:1 oil mix on temp 8 plugs. plugs seemed fine but swapped with a new set of 9s i had to test and still the same thing. so any help before i tear into it would be great. thanks in advance.

Are carbs clean? check choke cross over tube. It needs to be on even if bike is warmed up. Sync carbs. Check both cylinders compression and compare. If someone you don't know said they rebuilt the engine, then you need to check these things along with jetting and a leakdown so you will know what you have

my cousin rebuilt it. he is big on 2 strokes. he converted me from 4 strokes tonthe dark, and fun, side. lol. ill check the carbs tomorrow maybe. any gaskets or anything ill need to do th. at?

 

also tors and parking brake thing have been properly removed.

 

i ran a little seafoam (before i was told it could hurt them) and it made a world of difference. but being it has been cold up until today it could have even been from some icing in carbs. it was 40ish out today but has been high teens for the past week or so.

 

will the carbs go from in sync to out of sync like that though? cause it is always a 1-2 kick start.

also do you need any specific type of compression tester or will any decent conpression tester work? my dad is a mechanic amd i can use his matco compression tester if it will work.

The comp tester needs to thread into cylinder the same amount as your plug would. If the tester goes in deeper than plug would or less than plug would, you will get an inaccurate reading. Your problem could be one of many different things. Start with the simple stuff first. You don't need any gaskets to do a leakdown test or compression test. No gasket to sync carbs or clean carbs.

thanks. ill start woth carbs as soon as i can. ill try and do a leakfown as soon as i can as well. also i have a noss performance head on it. if i was to take it off to check the cylinder off, after checking other stuff first, what is needed for that?

sorry i probably sound like an idiot. being a little colder here im worried i blew it up.....
