will difference in compression cause hesitation??

[nickxc]

I have a slight hesitation when I am at about 1/4 throttle (in certain gears) im at the bottom of my power band but I am in the powerband. If I hit it right to the bar it hesitates just for a slight second. I have like 143 lbs in one cylinder and 125 in the other. This is with on the banshee that my buddy just bought so im trying to iron it out for him any info is greatly appreciated... Thanks!!

If I'm not mistaken anything more than a 10% defference is bad, so IMO that is enough defferenceto start noticeing problems

I think solo is right I think your looking at a top end. It could also be jetting. Have you cleaned the carbs out? Are the plugs wet? hesitation is a symptom of either over jetted or under jetting. The only way to tell would be looking at the plug to see if you over gased. My guess would be that you are jetted to high try coming down a jet size and see how that works for you. What mods are done to the banshee except for the valve's and cam's

HEHEHEHE HE SAID VALVES AND CAM HEHEHEHE DID YOU HOLD THE THROTTLE OPEN WHEN YOU RAN THE COMPRESSION? ARE YOU RUNNIN RACE GAS IN THAT. I THINK YOU SHOULD WITH THAT MUCH COMPRESSION.

lol hahaha

anyway... all it has is paul turner mids (for sale or trade if anyone is interested) boysen rad valves and a boost bottle ( as far as I can see. I had the exhaust off and I didnt see any port work) anyway it has 330 mains in it and my banshee with all the work listed below has 370's and IM a little on the rich side so I was thinking it is way over jetted... I did however richen the needles and it seemed to help the hesitation a little so I might try going up on the mains before I lein it out just to be safe... but that would mean it needs like 340 or 350 mains and I could run 350's on mine so that would be very weird. its prolly rich... if I have time I will dick with it this weekend...

well that is a pretty noticeable change in compression. but both are still in the ok zone. you may just want to get it honed and put some new rings on ur pistons and clean everything up and re-break it in. and if your noticing hesitation around 1/4 throttle thats the end of the pilot jet and the bigginning of the needle jet that controls that. try goin down 1 pilot jet size and puttin the needle jet position up 1. that will lean it out a lil bit. and do you know how to do a plug chop? i dont own a banshee but do they have a throttle limiter screw like a blaster? if so wind that screw in so you can only use 1/4 throttle and just hold it there and drive it down a straight away once you get into like 3rd or 4th gear (if you can at a 1/4 throttle) pull in the clutch while hittin the kill switch and remember to hold it wide open the whole time (and you have to do this with a new plug) now pull the plugs out of it and put new ones in. drive home and cut the threads off the plugs that you did the test in and the color under the threads on the ceramic should be a light tan. if its a whiteish burnt color its to lean. if its a dark brown to black its to rich.

I have done many plug chops tuning my banshee in after I had the motor work done. I should have done one on this banshee before I posted this question but I havn't had time and I just wanted to know if anyone knew if the difference in compression would cause a condition that mocks bad jetting. I am good at jetting and carb tuning and I know you shouldn't have a difference in compression if you can help it but I didnt know what the difference would cause. However. my buddy owns this banshee and he is planning on having the entire motor done in a month or so anyway so I told him to just live with it for now if he didnt want to take the time to try and iron it out. I would never take a 2 stroke apart without planning on putting a fresh bore on it and a piston and rings anyway but since he is gunna get it all done soon F-it live with it, ride it, and build it later. then jet it. no sence in getting all into jetting this motor correctly when he is gunna have an entirely different setup soon anyway..

THANKS FOR THE HELP THOUGH GUYS!!!!


Hopefully I wont have to ask this question agian cause he will take care of his new motor and wont have to worry about a difference in compression...
