    Detonation on decel . Ktm exc 300 2013

    We have only RON gas. What I find interesting is the difference between the gas from 2 gas stations in my town. Is about only 95 RON, if I put in from one gas station the bike run normal( this experiment was before detonation scenario) but if I put gas from second gas station, only 95ron gas, with the same jetting and the same temp. conditions the jetting seams rich. So this is a good or bad thing, about the gas? Can a good fuel to have this richer effect on jetting?

    Detonation on decel . Ktm exc 300 2013

    I'm sure about detonation on my bike. Because I was playing with jetting and have removed the effect for the most part. I'm use 95 octane gas. Is the lower in my country. To try 98? Now I have 40 n8rh#3 and 172,may be I can use 170 but I don't have atm. only 168 witch is a bit to lean. With 40p n8rw#4 172 was waaaaaay to lean on needle!! On WOT, when I was testing the jetting I could not stop the engine with the kill switch!!!!!! WHY DID THIS HAPPEN? N8rh#3 vs necj#3- the power is more pronounced with n8 on whole rage but is not so smooth on bottom like necj,and that because my AS is to much in. Tnx a lot for replay.

    Hmm. About AS, in this moment I can't open more the 1 turn out AS because the detonation is more pronounced. From what I know,detonation is lean effect from pilot,needle side. So more I turn out the screw,more detonation.

    SXS pipe I want to say. I know how the needle work, about clip position etc. I drop from 4 to 3 but I put in a richer needle. On keihin carbs the needles are made to work the best in 3 clip position so that is the reason why I try to find a needle that works ok in that position but to not have the detonation. About AS, I keep a bit open the throttle then I adjust the as until the idle is maximum faster.

    I was thinking about that but, isn't very common 42 pilot on ktm 300. On 250 May be. Next step is richer pilot.
  6. So bike is exc 300 2013. Head mod, squish around 1.38mm SXS front piece. Jetting: 40p N8RH#3 172 main j. As 1 Elevation 500-1200m Temp 15C My problem is pinging on deceleration. Was very bad with N8RW#4. On test, at WOT the engine start to detonat, I think, so bad than I can't kill the engine with kill switch!!!! With N8RH#3 I have VERY small amount of detonation. BUT is a bit too rich on bottom. I can't use leaner needle become detonation will start to hear. Idle is not so good, is like lean on pilot... What to do to clean up the bottom but to stay safe? I was playing with NECJ#4 168 main jet. Very clean on bottom and very good idle. But is a bit too lean for my taste. With suzi needle is richer in clip #3 ? can crank seal to have some effect to my problem? I have 185 hours on engine.

    Beta 450rr 2013 start easy on kick but not on estart

    My real problem right now is the spark. Starter spin well. All baring,crank shaft,piston,timing chain,cylinder all new.
  8. First thing to say is that: the bike was all rebuild. So no parts left to be changed. So problem is starting on button. If I crank over with kick starter I have spark all the time but if I use e-start I have only about 5-6 second spark and then stops. With battery in good shape I have spark if the amps drops a bit no spark. All the resistance are good. I have changed even the CDI , the same thing. Sometimes will start very quick on e-start ,sometime will start after 3 4 secs. Start on e-start only when is bike is hot

    Identify clutch model.

    I think the bushings were not in best form. But I can't find bushings to buy. Or dimensions of them.

    Identify clutch model.

    I have real issues with my clutch pulley from Arctic Cat 400. Will destroy transmision belt quickly. I knew he had this problem since I bought it. Now I need some parts from clutch pulley but I CAN'T FIND MY TIPE OF CLUTCH PULLEY ON OTHER Arctic Cat atvs. I try every year and model on arcticatparts.com and no one is like my model.

    Big problem with oil migration Beta 450rr 2012

    Is big question yes,and also a big problem for ktm 450 2008 too. The engines are quite the same in design. Anyway,the ex mechanic said it is impasibile to hapend that. Maby is mechanic's mistake,but we don't want to open engine and the problem persist.
  12. I can't find information about this problem. On my mate bike,oil from engine side will migrate on clutch side! The engine was recently rebuild. We can't trust in mechanic,maby he didn't changed the seals. My question is: is there some solution to drill a hole to crank case to have a continuous oil flow ? On KTM with the same problem the solution is to do a hole in a specific place.

    Compression ratio exc 250 2t 2011

    I have moded my cylinder head,I have around 1.45mm squish,is a bit large but is ok for now. Yesterday I made a compression test. My rings are at used at 60%. Is that ok? Is I put new piston in will be to big Compression?

    Power valve interchangeable

    Can I use power valve flap from 250 to 300 on ktm exc 2011?

    NEDW vs NECJ vs N3CJ

    Yes,I'm understand that. With needle is 1/5 clip leaner? I read that the N3CH is 1 clip leaner then N8RH. For example n3ch2= n8rh1 . And we know the n3xx needles are in 2 category n3cx and n3ex. So N3EH2 = N3CH 2.5 =N8RH 1.5 ­čśü On my case N3EH #4 = N8RH #3.5
