Are you sure you didn’t drop weights out of their channels when you reassembled your primary?Any way to make these makes have better throttle response from idle or a crawl? Once it revs it's got plenty of power but it sucks waiting for it to get there. Have grizzley weights and a 1.5mm shim already
from looking at your name are you from northern mn?The throttle response was better on mine with the stock weights on mine BUT didn't let the engine reach full power. I defiantly feel the power gain @ WOT with 20g Grizzly weights but it takes noticeably more throttle in the low-mid range area and really makes me glad I didn't get the 18g weights. Just installed a 1.5mm shim but haven't really got a feel for it yet as we still have snow on the ground.
