cylender issues PLEASE HELP

[bansheecrazy]

My banshee is driving me crazy. blew the top end on it about 2 months ago, ran it to lean and basically melted the vitos pistons. So i found a set of Jugs on ebay that were supposively ported by LRD, the guy claimed that it had 145 compression when he took then out. I received them they had a little wear on the cynlenders, So i honed them I then got it all together and I am getting like 110 max compression. I also installed the TORS removal tops on it while it was takin apart. The problem I am having is the it runs like sh*t in the bottom end and top end 6th gear but that could be expected. mid range seems to run great. I tried messin with the needle just gets worse, the plugs look good chocolate brown minimal wetness, then when I went to a neighbors house and was just idling, we noticed that the right FMF fatty pipe was getting hot but the left one wasn't. weird! I tried to change plugs and swap spark plug wires and see if there was a difference. none still right side allot hotter. My neighbor is saying it is the top end, I really dont want to resort to that unless I am totally sure. it is .040 now I think I might be able to go .050 but the machinist would have to make that call I am not skilled enough to know. I would like to just rering it, but cant find anywhere tobuy PROX pistons rings.

an help or suggestions is appreciated

I must say if I was only running on one cylinder I was hauling ass all over this Bombarbier DS650. I could only imagine what it will be like when and if I ever get this dam thing running right.

Sound lean on the main for being ported. start with a 340 work your way down. You need to rebuild the top end with that low comp. or at least try new rings. You should be at 140psi or so And for the pipe thing sounds like your piolet jet is plugged.

yeah I would definately put in a new top end at least some rings oif the top end is fairly fresh. I was running 110psi cold and it would drop to 100psi or below when warm and come to find out my rings had taken a shit on me.

well tested the compresion last night in the left cylender and it was 110 to 115 so next will be tonight if have time I will pull apart the left Carb and give it a good cleaning. I was thinking last night chilling with my neighbor that the right carb in the past was giving me issues and I pulled it all apart and soaked in Carb cleaner I will try that with the left one. I will keep ya posted, Keep up the suggestions, you guys rock thanks I will check that Pilot jet might be clogged hope that is it I dont want to rebuild.

Well heading in the right Direction, thanks to you guys.

I have cleaned out the left carb, did notice that the choke slide was nasty dirty. but took aprt the whol carb and soaked it in 3 bottles of carb clean for 2 day. put back together.I also went out an bought VP gas from yamaha, 105 Octain and the pro plugs for it. I ran it yesterday wil the 300's in it. seem to run a little groggy in 1st starting off, then took off great like in power band, after about 10 minutes of riding all the gears seemed to get groggy of the if not in powerband. I messed with the air screw didnt make it better at all. I put 310's in it last night left clip in middle and will try it tonight or tomarrow. Thanks for the help guys I appreciate any and all suggestions. I am thinking that a rering would deffinetly put me over the top after I get it running right. I just won a set of prodesign intake kit on ebay, so I will be putting that in next week would I have to jet up because of that normally or not

Take care

this bike is driving me nuts,

I tried the 310's I guess I was getting closer but then the plugs looked a bit lean, with the clip being in the middle. I then put in 320s wih the clip on the second from the top of the needle, this way it would be a leaner 320. now I am to fat it seems.

 

went for a ride on sunday like that it ran like hell for about 5 minutes then started to pop and sputter. adjusting the air screw didnt do anything, I am suppose to get the intake in the mail this weds or thurs, I am thinking that It might be a little fat and by putting the prodesign intake in maybe that will help a little. PLease HELP any suggestions would greatly help out. I am really going nuts over this. when I get the intake I will look over the reeds and the carbs again to make sure every thing is in good working order.

 

Any suggestions would help.
