  1. Ya I'm going to pull the jugs, check out the pistons and ring, do some measurements to get an idea of what I got, if all checks out good start testing electrical.
  2. All most forgot, this thing also has some pretty big carbs on it to, there 38s.
  3. Ya I thought about checking compression after the fact myself. Guess I might as well pull the jugs tomorrow and see what I've got and maybe do a rebuild or possibly a slight up grade. Was looking at possibly going 66mm pistons and with big bore jugs but need to figure out what has been done to it first, for all I know it's got big bore all ready. It had a crazy amount of timing advance at +8° when I got it last year.
  4. Little bit about the banshee, bought it a couple years ago and had instant problems with it first time out. Found water in the stator, flywheel area. Needless to say stator was shot and flywheel was rusted beyond belief. So payed big $$$ for all new electrical components stator, coil, cdi, wires, new flywheel, and adjustable timing plate. Plus found that the timing was advanced 8°. Put all together, set timing at +4° and ran it until last weekend, when it was really running awesome then late Saturday afternoon noon lost all power and ignition to left cylinder. Thinking fouled plug, pulled plug and it was little wet from fuel but in all clean, so wiped it down, ran wire brush over it, rechecked gap and put back in and fired it up had smoke coming out both pipes but still know power. So pulled head, pistons in all look good from the top but lots of carbon build up, plus the piston size is stamped on to of 65.19. There is a little play from side to side with both pistons, not sure if that's normal or not. Question is any idea what might be my issue might be and any idea what might have been done with this engine??? It has 65.19 pistons, CPI pipes, Cool heads with 22 domes. Haven't tore into it any further yet but plan on pulling jugs tomorrow.
  5. There 34mm keihin carbs, I'm going to pull them off and check the jetting on them. When I stab the throttle it's all most like it's not getting enough fuel but if I don't stab the throttle rpms will come up but then start bogging out again.
  6. Ok I've been cruising the forum reading different post, now looking for a little friendly know how from ya all. Ok going to my previous update and got Skeeter thinking now. Timing was set at +8° retarded to +5° bogged out when stabbed throttle from idle and seemed like it had no power, advanced timing back to +8° which I really do not like after reading a lot of post but it did get snappy and super fast again. Now when had it at +5° is it possible that it may have been carb issues at that point and who ever had it before used the timing to resolve the issue instead of doing things the right way???
  7. Plus I'll def bump up the octane from the 91, will have to hit all the gas stations and find who has the highest octane fuel.
  8. A little update on this crazy unknown banshee, ok pulled plugs didn't quite look like carbon build up, more of a burnt look but not completely black more like a dark brown and they were dry. Stuck a camera into each cylinder and all looked good, didn't see any scaring, pitting, burn marks, or carbon. Compression test showed 175 psi in both cylinders with 0 leak down for 6 min. Did the timing trial and retarded it back to +5° from +8° not good, lost a lot of power, throttle response was horrible, if stabbed the throttle it bogged out and almost died, put it back at +8° and it's back to crazy scary fast and hard to hang onto when going threw the gears and it's not slow shifting, you got to be on the ball because it tops out in rpms threw each gear pretty quick. Guess I'll leave it alone and run it like is and check the plugs at the end of each day of riding and stick the camera in each cylinder every now an then to see if any thing is changing.
  9. Ya I'm going to check out the plugs and do a compression test on it tomorrow, hopefully the compression checks good with no leak down but don't have much faith in the plugs being good, last time I checked them they were a little wet and had some carbon buildup but that was when the stator an flywheel went out on it due to water in the stator area.
  10. I'll definitely check compression, and start running 93 octane from pump. Was thinking about retarding the timing down to +4° or maby +5° and see what happens. Just bugs me to know end not knowing exactly what all has been moded and to what extent. Might have to strip it down do measurements and go from there.
  11. The carbs say pwk on them, not sure if that helps plus the both carbs each have a choke on the idle screw side, there the ones you pull up not out to the side. For fuel I've been running 91 pump fuel mixed 32:1, it's what the previous owner said he was running. That's why I'm a lot concerned about the +8° timing specially since it's only had pump fuel running threw it stated from previous owner.
  12. Lmao, guess I better just refer to it as shee.
  13. Just bought my first shee couple weeks ago, run great at initial purchase, got her home and went out that weekend riding some trails to get a little wind time which in turn lasted less then 30 min. Now to the main issues at hand, got her back home and started trouble shooting her, pulled stator cover off and about a cup or 2 of water poured out, trust me was not happy at this point. So in the end replaced flywheel, stator, cdi, and coil, put it all back together and set timing and everything back to how it was before issue, rode her all that weekend with out an issue and dang she is crazy scary fast. Now upon reading a few forums about the shee I'm getting a little skittish about running her anymore till I know for a fact as to why my timing needs to be set at +8° and the idle screw turned out 5 1/2 turns. I have found out there are mods done to her, gots 34mm keihin carbs, cool heads by pro design, cpi racing pipes, was told it's dune ported and bord but how far I don't know, and not sure if stroked or not but said something about +4. Any help greatly appreciated before I get stuck dumping more $$$ in her instead of doing preventive maintenance. Thanks greatly in advance
