As soon as my dad heard my bike pop upon shutting it off he said I need to adjust my timing. What is the stock timing for these things? Perhaps retarding it a touch would alleviate some of the back-firing issues. Brendan

Im going to tune it up this weekend. So you cant adjust the timing at all? Thats crazy. I just assumed it would be like my dirtbike where you can twist a stator plate back and forth.

Kropatchek Serious Thumper Offline Why more than 1 cylinder? Posts: 1457 Alphen a/d Rijn Netherlands Gender:	Re: Savage Timing Reply #4 - 07/27/06 at 02:58:08 Non adjustable timing. There's a Hall sensor inside the generator housing giving a pulse every revolution to the igniter unit ( CDI). CDI adjust the timing as follows: 5* +/- 2* BTDC at 2000 RPM 30* +/- 2* BTDC at 4000 RPM * = degrees, have no proper digit on my keyboard. This from the Suzuki WSM Greetz Kropatchek 8)

Even with an 86, it still has the lean condition unless someone has corrected it. Yes, there are differences in the needle and jetting in the early bikes, as there are differences between U.S. and European versions. You should have an adjustable needle so that you don't need to file the white spacer and your initial jetting is probably okay. You might need to rejet if you open up your airflow any more but the 155 main may be enough then too. Adjusting the pilot circuit idle mixture and changing the needle position will likely fix most of your backfiring problems. If not, start looking for intake or exhaust leaks.

Thanks for info re ignition guys.

My bike actually doesnt backfire much (only one poof upon shutdown), but its not running real well at all. I am convinced its not carby, hence why I am looking at the electrical side of things. I already have replaced the igniton coil and plug, now I guess Im going to have to think about the stator coils and CDI ($$$$). I have played the game before where I have stuffed around with carbies for weeks only to find it was a dud stator coil that was giving me grief.

Tomorrow Im going to set up the carb as per the reccomendations here, take it for a burn and see what its doing. If its still running poorly ill try a new CDI

The early bikes are subject to the backlash issue though. You may want to search for "stop the backlash".

geo Full Member Offline I'm a Savage Posts: 204 Orlando Gender:	Re: Savage Timing Reply #9 - 07/27/06 at 20:20:26 Get a SuperTrapp slip on. You will be impressed. The SuperTrapp eliminates the stock explosions. But it adds some between shift ka-pops. These are much more acceptable, and sound more agressive. The SuperTrapp mod is the most impressive change you can make to this bike.

And there are a number of aftermarket mufflers besides the Supertrapp. I'd also point out that a number of ride quality mods and safety mods would be what I would consider significant. A Xenon bulb is a quick and inexpensive way to be safer at night. Upgraded shocks and a fork brace really improve ride quality. I've also grown fond of my Amal carb. I like its simplicity and responsiveness.

Maybe this type of mod could be done on a Savage? http://www.sa750.com/timingmod/
