Purptruck2584 Posted August 30, 2022 Report Share Posted August 30, 2022 Lookin for another set of eyes on these plugs. Quad is 421 high port assassin from driveline 22cc domes, +4 timing Dmc 916s Stock carbs, uni pod filters 35p Stock needle middle clip 370m How do these plugs look? To me, im right on the fine line of almost too rich, but trying to get others opinions, some are saying its not rich, but too lean? Quad rides well. Slight stutter/burble in the mid range leaning the needle out will fix it, but then makes it too lean on decell and plugs get much whiter. Should i just leave the jetting alone and run it? The litttle bit if gray/ashy on the tip of insulator is whats throwing me off. Maybe the guys telling me its lean are just trolling? Ahaha Quote Link to comment Share on other sites More sharing options...
Purptruck2584 Posted August 30, 2022 Author Report Share Posted August 30, 2022 Also for what its worth 60% of the riding i do seems to be just crusin around 1/4 throttle, other than that its trails/high speed trails. Have tried a few differnt jetting combos, and this one is where it seems to run the best, without going too lean on the needle Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted August 30, 2022 Report Share Posted August 30, 2022 Strap doesn’t look right. Is this right after a WOT run? Quote Link to comment Share on other sites More sharing options...
Purptruck2584 Posted August 31, 2022 Author Report Share Posted August 31, 2022 Was after a pretty good WOT runs threw a trail, then some idling threw neighborhood (20 sec or so) Plug chops have always come out nice. Have been trying to dial midrange in a bit more, only seems to get a good mid range as i lean the needle out, but as i do that, plug coulor goes away, regardless of what jets are in the carbs. Ride better leaned out, by alot, but anything leaner than 3rd clip, and she sounds pretty angry about it, gets pretty tingy and lean sounding especially on decel. Have also found out the br8 may be a bit too hot and going to try a br9 as per driveline. Quote Link to comment Share on other sites More sharing options...
