74 T500 to lean

Post by RossB »

Hey guys
Thanks for all the help with my bike! Put in powerdyno ignition (compete system) ran it for a couple of
Weeks checked new plugs and there white as a ghost! The plugs looked good before new Ignition nice mocha brown. Im running stock jets with original air box and very loud Higgspeed chambers! Last time I tryed putting in 32.5 pilot jets she very wasn't happy. The mains are 97.5 now I have some 101 mains,really love taking carbs on and off witch way should I go for starters? Air screw 1.5 turns.
Thank you!

First I would recheck the timing - making sure that you aren't too far advanced. I would check with a dial gauge.

With chambers, you probably need a richer main jet. 101? 97.5, 100, 102.5 are standard round mail jet sizes.

Thanks
Will do I put in 102.5 mains taking it for a ride now. Bike starts great and idles nice just feel like it's a little slugish below 3k after that it's on! Think lean will do that.
Let you know how it goes.
Thank again!

Just went for ride with 102.5 mains she wasn't having any of it! Turned air screw out a 1/2 now at 2 turns out little better.I'm at center clip on slides might drop it down to lean side,timing right on.
She was bucking almost felt like when timing is wrong after 3k it was just ok.I'm running 30 pilots
When I ran 32.5's before powerdyno hardly could get it to run. I have some new needle jets my try them.
Peace!
