Video of the new bike

Well here's a video of the new bike and start up. I have a little bit of a skip or Miss to it but it runs pretty good so anyway here you go listen to it and see if you think it's the carbs needing adjustment.

Sounds ok to me. These tend to be lopey or cammy at idle.

Ahhh, It just seems to pick up and be smoother, then skip a little. I have some deceleration pops. Stock engine, no mods (coasters, etc). Just de-goated and Manual Chain Tensioners.

I've also noticed they seem to miss some when idle is too low. Desired idle is 1100rpm, or 1200 for CA models (probably just for emissions, i'd stick to 1100).

Speaking of MCCT's and Caliulcans . . .

I had your previous comments in mind ( from your chats with Wolfie and Doc ) when i designed an MCCT mod today. Would appreciate your critique of what i've put together before slapping it on the bike. Will post in a different thread.

Has a lot deeper throat tone than mine. I swear mine reminds me of a Honda sometimes.

Have to agree with above though, increase the idle or let it warm up with the choke, either way... was that a cold start?

It wasn't fully cold, but wasn't yet to the first line on the gauge. I like my bike to idle low and hit a lick, but was just making sure the stutter and miss wasn't a carb issue since I was popping on decel (something I actually like to be honest... just wanted it to be running right though).

Mine is an 87 California emissions model. The popping ( from what i read ) is supposedly blow-by that gets redirected though the charcoal filter and sent to the exhaust manifold to "explode". I have yet to mess with the carbs on mine except the idle, not the screws. But even cold, mine idles fairly even with a "longer term" cycle before it does a "rumble" skip a beat and recovers. When i have it on choke cold, and as i nudge her down, she will meet popping spells at various RPM, i.e. without any de-accel, just okay, it's 1152 RPM now, guess i'll make popcorn. Then lower RPM... fine again, then lower, another range of popping, etc.

Now if that popping is something else, like a backfire, then i want it gone, and around here, there are so many bikes, the poppy sort are usually the rag-tag sort using a bent piece of concrete-rebar for a sissy-bar, and made with half jap half harley parts and a carb from a Briggs and Stratton... so.. just me, but even though i am just as rag tag as most of them... it gives me the creeps, to put it plain. All the work i put in her so far and it pops? :/

She backfires louder than a double-barrel shotgun though, when she does ( battery bad, flood clear, whatever ).

Will yours change RPM if its moved from side kick stand to standing up for a ride?

BTW, i am jealous of your tach. Mine was broke day i bought her.

I believe that indicates low carb float levels.....adjust float levels to alleviate
