I'm looking the plastics shift drum cover with the 3 mounting screws and oring, I know someone has some junk cases laying around with this stuff still in it, thanks
My 10 mill 465 cub went 3.70s with my chassis builder bracket racing it, should have gone high 3.60s if he hadn't lifted, rider was 200lbs and bike was 220ish
These are pe-1 needles. They do make longer needles for 48mm up but there a different numbered needle pe-5 or pe-6 can't remember but pe-1 is the standard from small lectrons up 44s or 46s.
On our 7 mill stock Cyl bike we ran several 4.0s n its a +13 arm. But the hole bike ready to race was 270lb with 180lb rider. With 1.40s 60 ft. You can make a long arm bike work.setup is key
