Speeds?

No races for me the weekend the snow on the bay is rock hard and all im doing is spinning. 500' went down to 71mph and 1000' to 91mph

turned out the track was a little better today top speed went up in the high 90's and I took 1st in the drags

We have some of the best racing conditions here now we had all year. I have the apex pretty close but im still losing rpms on top. I ran the sled little over quarter mile, added trottle slowly from start to wot and it builds rpms perfect till its almost full open. At around 3/4 trottle i see 10200 after that it loses rpm then at wot im back upto 10600 and it dosent seem to pull much if any after 3/4 trottle. Its darn near perfect i seen 127mph on the speedo (never had my radar gun with me) which is the best i have seen to date but im thinking i need a stiffer spring in the secondary. Im maxed out on the white yamaha spring what is the next to that? color? or do i go aftermarket if so where can i get one?
thanks

Would it act like this if i was just running out of gear?

Yes when your out of gear it hits a wall and feels like a engine problem, regear and your good to go!
