just got my bike back with the Jars.......................tech put in the Triumph 49 tune...........I had a bypass on the cat..........but i guess that is built into the Jars...............runs fine...........but LOTTA decel popping...............if this is normal...................until i get the TB.............I can live with it......................I just have to use the clutch around cops when slowing :wink: ....................................so.....................is this normal?
Although I don't know what a Triumph '49' tune is... I would say the decel popping is normal, and not to worry. No cat bypass on the Jars because there is no cat. :wink:
You can be rich as hell over 6% TP and lean at idle, and the Jars will pop when you close the throttle on decel. I'm sure Jethro has succeeded in freaking Humble out... so Humble, just pull a spark plug and take a look. I bet nobody has been leaner than me (AF 18.5) and it took WAY more than just Jars to do it.
Checking the spark plug right away is a great idea, IMO you are lean through most of the rpm range. But then again, I had done the triples
also, so I was much more lean than with the stock intake. That reminds me, Humble, if you want the most out of the Jars, do the triples, the combo works great together.
i saw the sheet he took it from.............said it was a new tune.............dated 2007..................i thought it was odd i never heard of it....................too bad we cant get a freekin' list from Triumph.
the pipes were so loud.......i didn't hear the FHP pulling our group over today..........gave the leader a fast driving award.............and after looking at my license and insurance card.,( I was second in the group, right behind the leader.)....................and NOT noticing i had NO bike license or even a learners permit. ...........gave me a warning for "following too close" :wink: I didnt want to tell the cop.........I was right on him....cause i was SLOWING DOWN to turn....LOL I had already told the group.............."looks like i get a free ride in a police car. So after lunch................the leader was a tad hesitant to hit the throttle..................so.........TA DA................i led em home hitting 120......and bouncing off 130................thinking.............."sure hope Jethro is wrong!"
P.S. fast driving awards are going for $180. US at that speed. :wink:
