Hello! As the new season approaches I am working with my local shop to diagnose and fix a problem that crept up last year, we are all ears and hoping someone can shed a little light on what may be happening and how to address the issue. Here's the scoop -
86 Savage, had it 4 years, runs beautifully when it runs. Nothing too major done to it but I have swapped for a Raptor petcock, it uses a K&N filter, and I went up a size on my main jet and did the spacer mod (it was already done I just replaced the washer once) which decreased backfiring and ran a little stronger. Otherwise I have replaced the iginition coil and starter when they began to falter but no other special work to it.
Late last year it began to cut out at mid range RPM, whether in gear or not. It would idle strong, then when gassed it would rev up and begin to 'miss' then backfire, then choke out if you did not let off the accelerator back to idle. As it would continue to idle it would get worse quickly, eventually failing at lower RPM and not recovering at all. I would let it sit a while, usually charge the battery or something, and repeat the process.
I have the bike at Moto Classic Garage in Los Angeles, good guys and familiar actually somewhat with the Savage. They cleaned and checked the carb, checked the plugs, compression, fuel system, and went through some basic diagnostics. They have another Savage in the shop and have even gone through swapping pieces between the bikes to try and find the problem but no luck yet. One mechanic thinks it is related to timing but not sure how to be sure, the other wants to plug into another black box and see if that reveals anything.
So I am asking for any advice or suggestions, we are all pretty curious at this point what is happening ha, and as it gets warmer every day I am certainly motivated to get it back on the road. Would the cam chain adjustor play a role in such a problem? Is there another way to check the timing or a related component we have not tried? Does this sound like a problem we simply haven't thought to look for? Or is the black box truly the next thing to swap?
Thanks so much in advance, this site is a great resource!
