justinklumb29 Posted June 3, 2006 Report Posted June 3, 2006 shee ran great a couple of weeks ago, then one day wont go over half throttle, I put new carbs on, new plugs, tried different jets, but i dont think it is jetting as pulling out the choke has no effect on performance. Its not the choke tube, i got that in there. It also has a new stator. Any ideas??? Quote
ssanddemon Posted June 3, 2006 Report Posted June 3, 2006 (edited) The very first thing to try is to make sure that the coil ground connection is good and tight, and that the frame is clean where the coil ground attaches. Make sure the coil connections are tight and clean. Edited June 3, 2006 by ssanddemon Quote
gipperz Posted June 3, 2006 Report Posted June 3, 2006 If you have'nt disconnected the tors system yet, it might be your problem. Just an idea. Quote
justinklumb29 Posted June 3, 2006 Author Report Posted June 3, 2006 tors is gone, i will check the ground connection Quote
justinklumb29 Posted June 4, 2006 Author Report Posted June 4, 2006 the parking brake is disconnected and the ground has a good connection, does any body else have any ideas, it starts hard, i usually have to pop it just to get it going Quote
creamsickle Posted June 4, 2006 Report Posted June 4, 2006 dont change the jetting. if it ran good before there is no reason why jetting would have to be changed. try switching the plug caps. start small then work up to the bigger things. make sure it has spark. clean off the top of the plugs so that they have a good connection. not really sure what you mean by it running like crap but make sure you take off the reeds and look for cracks chips or gaps in the peddles.

fox_forma Posted June 4, 2006 Report Posted June 4, 2006 what did you do when you changed the jetting? If nothing else is working that is mentioned I would assume your jetting is way off, normally its a lean condition when something is hard to start and it needs to be pop started. Also make sure you have no air leaks anywhere as well which could cuase a world of trouble starting it and even in the short/long run if you have been running it this way Quote
justinklumb29 Posted June 5, 2006 Author Report Posted June 5, 2006 the jetting is not lean, i went down one size to a 320 from 330 because of the warmer weather. The problem started before i changed the jetting. One day it just was a pain in the ass to start and will not rev over half throttle. Every time i go over half throttle it backfires like crazy. I am switching out the reeds with some other ones i have laying around. The ones in there do not look back. No chips or cracks. However there is a tiny gap between the pedals and the reed case on some of them, Could this be my problem? Quote
fox_forma Posted June 5, 2006 Report Posted June 5, 2006 yeah a gap between the reeds and the cage is not good so it could be your problem, hopefully it is something simple like that, what size are your pilot jets as well, the reed problem with gaps can make a bike hard to start. Good luck Quote
justinklumb29 Posted June 5, 2006 Author Report Posted June 5, 2006 i got 27.5 in for the pilots and i put different reeds in and nothing changed, had to pop it and it would not rev over 4000, it is like there is a rev limiter on it or somthing. any other ideas??? Quote
ssanddemon Posted June 5, 2006 Report Posted June 5, 2006 Is it running the same on both cyls? I mean when you hold your hand behind each silencer, does it feel like one is running better, or popping harder than the other? Quote
kb7kuh Posted June 5, 2006 Report Posted June 5, 2006 Sounds like the same thing that happened to me with v-force 2 reeds. I still had the stock reeds and put them in and it ran fine, and started on the first kick. It was more like you said, it was a bear to start, but ran ok. After having the v-force, the stock reeds sucked so I went to V-force 3's and all is well. Quote
fox_forma Posted June 6, 2006 Report Posted June 6, 2006 by chance could you need new top ends? How many hours are on them? Jetting doesnt sound to bad but I would think you need your pilots up higher, maybe around 35's instead of 27.5's but if you said it was fine before i'm not sure. Sounds like a lean condition somewhere because of how hard it is to start when it finally does, thats what i would think, pilots are to low, air leak somewhere or the reeds were your problem but i guess something else is going on. How long did it sit for before this happened to you? Possible your floats are off, sometimes that can describe what is happening, when your getting in the higher RPM range possible not enough gas is getting through or maybe a ring is stuck...... Quote
Justintoxicated Posted June 6, 2006 Report Posted June 6, 2006 This is what mine was doing when it was time for a rebuild. It would run but not very good.... Quote
