honda_tlr Posted April 1, 2007 Report Share Posted April 1, 2007 (edited) Hi, my TLR (ever since I bought it off sandy) has had a mis fire at high revs , now then I have put up with it as it doesn't matter for trials. but I want to sort it I have: standard exhaust, New plug, Set the tappets and Cleaned the carb. And I even took the plate off to get to the fly wheel, now then I have a TLR manual and have set most things to there right setting. You know under the fly wheel cover is there anything that can be adjusted under there that would cause a mis fire? I also have a timing gun but haven't tried it yet as it needs to be dark for it to work. If I use the timing gun and find that the TDC mark is not lining up when it is firing what do I adjust to get it to fire at TDC ? I used to have the old TL 125s and they had points thus meaning that I knew how to sort them , but the TLR being a TLR has a bleeding ECU ! If any one can just say go look at page ... then please say Ride safe. HONDA_TLR. Edited April 1, 2007 by honda_tlr Quote Link to comment Share on other sites More sharing options...
max1956bikes Posted April 1, 2007 Report Share Posted April 1, 2007 dont touch anything to do with flywheel.a high speed misfire most likely not carb if it runs well otherwise,if it misfires in neutral at stand still try taking of ht cap get a mate with rubber grips on pliers to hold ht lead slightly away from end of plug say few mm start up bike and see if spark works ok when it misfires,if no misfire replace ht cap Quote Link to comment Share on other sites More sharing options...
honda_tlr Posted April 2, 2007 Author Report Share Posted April 2, 2007 I have just ordered new (standard) jets for the carb as the jetting was wrong (wrong as in not standard ), the needle setting was wrong, it was not at the standard place, it was set lower.

brian r Posted April 2, 2007 Report Share Posted April 2, 2007 You also may want to try disconnecting the kill switch, it could be arching at high revs. Quote Link to comment Share on other sites More sharing options...

brian r Posted April 10, 2007 Report Share Posted April 10, 2007 Did you get it fixed? Quote Link to comment Share on other sites More sharing options...
honda_tlr Posted April 10, 2007 Author Report Share Posted April 10, 2007 No , the smoke coming from the engine suggests it needs new piston rings, and a new cam chain , any one know if Quote Link to comment Share on other sites More sharing options...
honda_tlr Posted April 13, 2007 Author Report Share Posted April 13, 2007 I put new rings in it , it has more power and better responce but still has the problem with the miss fire. note it is not a BACKFIRE, so does any one has any ideas what it could be ?
