Title: Rejetting with DynoJet tonight... Post by trapper_canada on 07/02/09 at 13:08:20 So I got my DynoJet kit today. I can't believe I spent $80 on that...but if you procrastinate then you PAY the consequences... Oh well... Anyways I did some reading on the forum and there appears to be a discrepency between the dynojet jets and the others... no 150 or 155 but these silly DJ140 or DJ144. The instructions say to use the DJ144 so I will give that a go. Now, included in the kit was a new fuel needle. It says to use the 4th notch and the stock white spacer. Now I already replaced my white spacer with a new one @ 1/2 thickness. Does that amount to the same as this new dynojet needle? I don't much feel like removing the carb again. I already replaced the bottom 4 bolts with hex so I figure I can relatively easily do the rejet with Carb intact. Anyone with any insight on if the 144 jet is good (stock airbox w/dyna muffler)? And if anyone else is looking to rejet...do not waste your money on this DynoJet kit.... ::) |
Title: Re: Rejetting with DynoJet tonight... Post by trapper_canada on 07/02/09 at 19:10:32 OK...I put the DJ144 DynoJet needle in. I fired it up...and it ran MUCH better...at first. I gave it a couple good revs and there was no backfire or popping. I took it for a spin and it is still backfiring. However it seems to really back fire on hard acceleration??? Now when it is idling if I blip the throttle it will backfire. Loud snap sound. Any ideas what this might be? I can't "feel" an exhaust leak. I might try loosening everything and then trying to make sure everything is tight. Any ideas with what could be going on? |

I am in ottawa. I had to use the 146 main from the jet kit with my sporty muffler I had at the time. my carb already had a 145 in it at the time. The 146 reduced the backfires to crackles and only a poof on shut down. I really would use the spacer provided in the kit. After all you paid for it. and yes they are a rip off. All the pieces bought separately would only cost you 30$ or so lol. Dont forget to adjust your air mixture and idle as well. |

They use different numbers than the DynoJet. |
