tabshee Posted May 2, 2004 Report Share Posted May 2, 2004 Sorry for the lengthy post but I want to explain everything: I bought a 99 shee for next to nothing because a friend of mine got extremely frustrated with it - he had it rebuilt and it was still running like crap. I took it and tore it down and discovered that the c-clip was missing from the wrist pin - it had popped out and tore the right side up - piston and cylinder wall was pretty bad. I sent the cylinders out and had them bored 80 over to get the gouge out and boutght new wiseco's. I split the case and went through everything to make sure all the metal was out of it. I put it back together and did a compression test and got 120 per side (really should be more shouldn't it?) anyway I completely went through the carbs making sure everything was clean and I replaced the tors with new carb tops - drilled and tapped for the idle screws. As of right now it runs like CRAP - starts fine and idles ok but is extremely flat from mid too top - seems like there is no powerband whatsoever - just winds up like a four stroke and stays flat and slow - completely missing any punch. The carbs are in sync I have checked and re-checked three different times. As far as an air leak goes - I do not have the means (tools) to pull a vacuume on it and do a leak down test and I hate to get bent over by the shop. This is my 3rd shee and it is definately not a charm. By the way all stock accept for the tors removal and the bore. Any suggestions would be greatly appreciated - next step is nailing a board on top of it and using it as a coffee table!!! Thanks. Quote Link to comment Share on other sites More sharing options...
reas11 Posted May 2, 2004 Report Share Posted May 2, 2004 whats your elevation , and what size jets u running.. the jets can cause it to run like crap if they are really fat . Quote Link to comment Share on other sites More sharing options...
Banchetta Posted May 2, 2004 Report Share Posted May 2, 2004 Easy fix, look above the left exhaust, you'll see a little black box w/ a 3-wire plug, unplug it, next....go to the handlebars and follow the parking brake switch wire towards the gas tank to another connector, disconnect it.....That'll completely disable the true TORS system.....Throttle Over Ride System.... Next, check to make sure your choke tube is in place between the two carbs..I doubt this is your problem since its your 3rd shee and it idles fine, but covering everything...... If problem persist, check the slides in the carbs to make sure the cutaway is facing the air box..... If problem still persist, bring it to Maine and I'll check it out....

tabshee Posted May 2, 2004 Author Report Share Posted May 2, 2004 Wow - thanks for the fast response!!! Elevation is 450 I think - Columbus, OH - jetting is bone stock and as clean as a whistle - played with the clip setting but didn't make any difference so i set it back to factory. Banchetta I'll check the rear but I think I have it all disconnected including the parking break (I hope I am wrong). I grew up in Portsmouth, NH and if I still lived there I'd bring it to you. Thanks again - just out of curiosity where in Maine? Quote Link to comment Share on other sites More sharing options...
tabshee Posted May 2, 2004 Author Report Share Posted May 2, 2004 Banchetta - just noticed your info - should have looked before I asked - Saco huh? Ayuh betcha got one wicked banshee bub. I miss the Lobster - buck a pound off the boat - used to eat it till I got sick from the butter - wicked pissah!! Can still taste the fried clams from the clam shack - out here clams don't have bellies - just necks - like chewing rubbah bands. Quote Link to comment Share on other sites More sharing options...
boonman Posted May 2, 2004 Report Share Posted May 2, 2004 Even if you have the parking brake disconnected, you still need to unplug the brain module from the system. WHich is located, as mentioned, above the left exhaust. There are 3 wires on the plug. Disconnect it and see what you got.... Quote Link to comment Share on other sites More sharing options...
tabshee Posted May 2, 2004 Author Report Share Posted May 2, 2004 Guys - I checked out the "brain module" in the back just above the left silencer (black box) but there are a lot more wires than the three mentioned. There are 2 connectors each with definately more than three wires. I tried every combination you can - both unplugged - one unplugged etc. and everytime got no spark - hook them back up and spark. The parking brake assembly has been missing since I have owned it so I don't think thats a factor. As you can probably tell when it comes to electrical my IQ is about 10. Why do I do this ----> <----- Cause it feels so good when i stop. Thnaks Quote Link to comment Share on other sites More sharing options...
tabshee Posted May 2, 2004 Author Report Share Posted May 2, 2004 DOH - just dawned on me - exhaust not silencer - I was unplugging the CDI - LOL what an idiot - the box your referring to has been unplugged I pulled it when I replaced the TORS. Wish that wasn't the case but it is. Sorry - The doctors tell me I'm only slightly retarded, sometimes I think there just being nice.

Banchetta Posted May 3, 2004 Report Share Posted May 3, 2004 Yeshaa, dat Maine lobsta is wicked good!!! I have a 40' lobster boat..... One of my trades...Ok tors is removed, needles are stock position,, stock jetting,......Did you check the choke tube between the two carbs?? PUll the air cleaner and look into the carbs to see if you can see the cutaway in the slides (slant) Quote Link to comment Share on other sites More sharing options...
tabshee Posted May 3, 2004 Author Report Share Posted May 3, 2004 Choke Tube checks out - slides are good - now I am not going to profess that I am an expert adjusting my carbs - I have tried adjusting my air - fuel mix by starting at the factory setting (2 turns out) and working in - I did notice some improvement at 1-1/2 turns out. I just have a gut feeling that it's carb related but I have been through both of them several different times. STUMPED. 40' Lobster boat WOW thats a big ass boat. When I was 15, dumb and crazy (good combination) My friend and I took a wooden row boat with a 10 horse motor and went out to the Isles of Shoals only to be escorted back by the coast guard out of Newcastle - Thank God for perfect weather or we would have been swimming with the blues (September). I really miss the Seacoast. Only one memory from Saco - I hopped the BM train out of Dover thinking I could get off a mile up the tracks at a friends house - nope...... train was going 30mph had to stay on till it slowed down enough in Saco where I jumped off and hitch hiked back. I am now 39 and own 2 Banshees - my friends with their 4x4 - four bangahs think I'm nuts but I don't mind when we go riding they spend the day eating dirt sandwhiches served up by my shee (the good running one). Thanks again for the help guys. Quote Link to comment Share on other sites More sharing options...
Banchetta Posted May 3, 2004 Report Share Posted May 3, 2004 what is all your jet sizes? clip position on needle? timing advanced? Quote Link to comment Share on other sites More sharing options...
tabshee Posted May 4, 2004 Author Report Share Posted May 4, 2004 Jet sizes are stock, clip position is 3rd groove (stock), timing hasn't been touched. Quote Link to comment Share on other sites More sharing options...
350duner Posted May 4, 2004 Report Share Posted May 4, 2004 Slides are in the right carbs aren't they? Not reversed? Are they opening all the way? Quote Link to comment Share on other sites More sharing options...
bigboybanshee Posted May 4, 2004 Report Share Posted May 4, 2004 Just a thought but here recently my shee was running "flat" kinda like you're describing and the reason for it was because my outerwear was clogged with dirt and was starving my engine for air. Took off the outerwear and she ran like a scalded dog! Considering you said your jetting was stock and it definitely shouldn't be too fat I would check your airbox and the condition of the air filter. If it's dirty yank it out of there and make a quick run and see if that helps. You might just need a different/new filter. Just my feeble attempt to help!! Sucks to hear you're having so many problems! Quote Link to comment Share on other sites More sharing options...
tabshee Posted May 5, 2004 Author Report Share Posted May 5, 2004 Slides are in the right carb - in fact one of the firsts things I do when I get a banshee is mark the tops and the spark plug wires left and right - I have mixed them up before - I will however yank the filter and see what happens - I'd be happy with a dog that ran like it had a mild burn . I really appreciate all the help - these things can be frustrating, but to be honest the learning process is half the fun.
