Is he giving it to you or do you have to swap him your stock one for his cut one? I ran one for about a week or two before I swaped mine out. Just about all it does is make you banshee "Sound" fast. It will rev up quick in neutral. It will be easier to bog launching off the line, and it will fall off the pipe easier. Quote Link to comment Share on other sites More sharing options...
sstaton1983 Posted April 21, 2011 Author Report Share Posted April 21, 2011 i would have to swap. i always heard friends say that less weight on the crank makes the engine lose tourqe. Quote Link to comment Share on other sites More sharing options...

mopar1rules Posted April 22, 2011 Report Share Posted April 22, 2011 I had my flywheel lightened last year and did notice that it would slightly rev quicker when in neutral and when driving it. I paid attention for it wanting to fall off the pipe easier and for it to be doggy on the start, but noticed it hadn't really changed from when I had the stock un-cut flywheel on it. Maybe I got lucky?? Lightened flywheel seems to be working for me. Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted April 22, 2011 Report Share Posted April 22, 2011 Yes the bigger you are the more you notice it. I weigh 250 and didnt like it. It also depends on who shaved it and how much they took off. Quote Link to comment Share on other sites More sharing options...
mopar1rules Posted April 22, 2011 Report Share Posted April 22, 2011 (edited) how big are you? i was told that they work best with a light rider. i only weigh around 145 -150. i'm a little guy.......144 to 147 lbs (depends which scale i go on :=) there was material taken off of the O.D. on both sides of the 2 nubby things, where the pickup coil gets its reading/signal from. there was also material taken off the face of the flywheel.

camatv Posted April 23, 2011 Report Share Posted April 23, 2011 they add tq.... if it falls off the "pipe" its ported a lil wrong or jetted a lil wrong.. OR being ridden wrong ( shifted to early, overreved to far THEN shifted ETC) i like a lighter flywheel i like the quick rev of the engine. i have ran ones with about 60 tho taken off i weigh 280lbs!! i have had one on my trail bikes and my race bikes for a long time i didnt really like the PVL ignition's/.// Quote Link to comment Share on other sites More sharing options...
