bansheeman1974 Posted February 4, 2006 Report Share Posted February 4, 2006 id bet a dollar it is you cross over tube not the metal one that goes on tope of your reeds it is the little rubber one that goes carb to carb. Quote Link to comment Share on other sites More sharing options...

Wallrat Posted February 4, 2006 Report Share Posted February 4, 2006 Holy hell dude! So when you say u tried swapping every electrical componant did you try a whole new harness too? After reading everything you've done my best guess is some kind of wiring issue. Try swapping out everything elec., wires included from a running bike. If it doesn't work then we definately know its not electrical. Quote Link to comment Share on other sites More sharing options...
BansheeGuy_IV Posted February 4, 2006 Author Report Share Posted February 4, 2006 Hey guys, Just to clarify some.. I swapped out every electrical component, including harness, switches, key... I decided to try it, after testing them all with voltometer/ohmeter as a just in case measure. I even swapped the CDI, stator, stator plate, flywheel... All from a known, running bike. The TORS crap is GONE. I swapped three sets of carbs. I swapped another stock pair. Then I swapped a pair of aftermarket 28mm carbs. All with the same result. There goes any theories about choke tubes, clogged jets, or worn slides. I swapped the entire intake boots with another set of stockers and then a pro design manifold. I swapped out the reed cages. Another stock set and a V-Force set. I swapped from right to left. I swapped heads. I swapped out the left cylinder. I completely replaced the cases... Brand new from the factory cases. I swapped out the crank seals for a second time. None of it has made any difference. The last thing left... Is the crankshaft itself. It's a brand new Wiseco Hotrod stock crankshaft. I'm going to swap that out next. It could be the metal seal between the crank is bad... Or maybe it's just a defective crank all together... Something that I can't explain... I've run out of any other options. Basically the problem is affecting combustion in the left cylinder. I tried to go from easiest to hardest, eliminating any possibilities for what might interfere with Combustion. I've probed the minds of builders and shops from the east coast to the west coast ... The best answer I received so far... Is from an expert out in CA... And like he said to me... He once had an RD400 that he basically swapped everything out like I've done, and every time he'd run it... It would seize up... And he never found an answer. All the components were good, just something didn't work right together. I may be coming to the end of the road with this engine. BG Quote Link to comment Share on other sites More sharing options...
2twin350s Posted February 5, 2006 Report Share Posted February 5, 2006 you said the motor siezed once. have you checked the water pump? does the bike run good at all?and then start runnin shitty?the only thing i can think of that you have not eliminated is CASES or cooling problems cuasing the motor to seize.you said you got some used cases correct? you did leak down and checked ok.but does not say that there is a leakdown between both cylinders. you have swapped carbs,coils,reeds,jugs,electrical,head.possible it could be the crank not being trued? or cases leaking air.but if you siezed a piston and the bike runs good until it seized,i would say water pump problems could be in order.the left cylinder is the last one to get coolant flow.so a weak water pump or cooling system could be the culprit.i have seen this happen on tri-z trikes.the impellar slips on the shaft and boom.there goes the piston and rings.just my 2 cents.good friggin luck with that one.did you rebuild the water pump when you did the engine? be honest.a lot of guys just pull the clucth cover during a rebuild and never do the pump.i would say check the water pump regardless.no one ever mentioned that and if the motor ran good for a minute or so then got hot and ran like crap and siezed rings on the left side.that is a cooling issue.especially since you have eliminated every thing else.i have extensive engine building expereience and i know my idea may be far fetched but worth a try. and i did read all the posts on this topic.water pump or cooling has never been mentioned.could be the problem Quote Link to comment Share on other sites More sharing options...
BansheeGuy_IV Posted February 5, 2006 Author Report Share Posted February 5, 2006 The water pump is a good thought. I replaced the impellar and seals. The problem is from the moment you start it up. It spits fuel out of the left cylinder... It runs on and off... About 50% of the time. It'll do it ice cold. It'll do it warm. The time it seized was mostly my fault. Out of frustration and trying to ride it... I cold seized it. The seize didn't cause the problem. The problem caused the seize. BG Quote Link to comment Share on other sites More sharing options...
bhatch21 Posted February 10, 2006 Report Share Posted February 10, 2006 you might try checking the silencer packing on your pipes. it could be clogged and need replacing. a difference in back pressure might cause the left side to miss. i have 3 stock banshees. 2 of them fire more out of the left side than the right. i gave up looking for the problem long ago after doing much the same stuff you described. i just adjusted the carbs for those sides differently. they don't foul plugs or seize cylinders. hope this helps.

easyrider470 Posted February 21, 2006 Report Share Posted February 21, 2006 i just had this problem.....literally YESTERDAY.....i thought electrical i thought T.O.R.S.control unit i checked every wire.....it ended up bieng that the carb WAS NOT getting enough gas to fire the left side cylinder.....have you pulled off the fuel line and turned the fuel shutoff valve to the on position? you should have an even flow of fuel.....if nothing comes out try it in reserve......trust me i know this seems stupid but i just had this problem and it ended up that the fuel just wasn't floing enough to my left cylinder......pull out that petcock and clean the screens and check for foriegn matter in the tank....it's worth a step back and another look Quote Link to comment Share on other sites More sharing options...

Gas cap vent? Anything new on this problem child? Quote Link to comment Share on other sites More sharing options...
jmurrayR6 Posted February 24, 2006 Report Share Posted February 24, 2006 Just solved my right side problem. Just bought it in to get checked they checked the one thing I did not. I was missing 2 reeds. Thx god I can get a set for 4.99 on ebay stockers and call it case closed Quote Link to comment Share on other sites More sharing options...
BansheeGuy_IV Posted February 26, 2006 Author Report Share Posted February 26, 2006 Hey Guys, To conclude this thread... I finally got it fixed. Here is what I replaced... Head, Cylinder, Crankshaft, cases, primary drive gear (just because it was worn), flywheel, stator, wire harness, coil, wires, plugs... Two sets of reed cages.. And then I swapped out yet ANOTHER set of carbs... And finally... The combination of everything... "Something" I can't explain... It's fixed. My friend is one happy camper. After alot of time and effort... Took months actually... It's fixed. ;-) This was the toughest problem I've ever faced. BG Quote Link to comment Share on other sites More sharing options...
