boonman Posted April 9, 2004 Report Share Posted April 9, 2004 How much does lightening the flywheel usually cost? usually around $100 + shipping How much would you do it for Boonman, and what about the shift star? $65 including shipping gets ya 9 oz. removed and the shift star mod with neutral backcut is $25 including shipping.... How will lightening my flywheel go with my ported engine. Will it be good for hill climbs? HELL YES!!!! In a hill climb, you need power when you want it, and you need it NOW!!! You are on the gas, and then the front end comes up a little, you back out a touch. Now the bike falls out of the powerband. you hammer it, and it doesn't do anything but bog. With a lightened flywheel, problem goes away. INSTANT throttle response. what the best way to contact you Private message through this site. Being that my email is down, and I don't have any untill I find another email place.... Quote Link to comment Share on other sites More sharing options...
blazenlo Posted April 9, 2004 Report Share Posted April 9, 2004 Excellant reply boonman. By the sounds of this mod I may just have to get this done. Quote Link to comment Share on other sites More sharing options...
oldturtle Posted April 9, 2004 Report Share Posted April 9, 2004 I keep coming back to this thread waiting to see the negatives of lightening the flywheel. How about hearing from the novice trail rider that had it done or don't we have any on this site. I added a flywheel weight to my KTM250EXC to make it more controlable in the gnarly wet log and rocky stuff I ride that bike in. Granted the shee will never see that stuff while under my sorry ass.

fixitrod Posted April 9, 2004 Report Share Posted April 9, 2004 I read some stuff on the eric gorr web site about this mod. When people say you'll have less torque. If you have a two stroke that doesn't have torque... how are you going to loose it. The engine creates torque...not the flywheel. You have to remember what a flywheel if for. Momentum to keep the motor running and it can aid in keeping if from stalling. Who rides a shee at such a low rpm that it's going to stall. With a twin cylinder you have plenty of momentum.

nickxc Posted April 9, 2004 Author Report Share Posted April 9, 2004 Thanks alot guys I cant wait to get mine back and try it. Im really glad to see all the positive about this I was sure Id see some negative replies. I ride in all sorts of different terrain. I have dunes, long dirt roads, and really tight, wet, muddy, rockey woods around here in NY and I ride it all. I'll let everyone know what I think of this mod once I have a chance to try it out in some different places. thanks again!! Quote Link to comment Share on other sites More sharing options...
SICK BOY Posted April 9, 2004 Report Share Posted April 9, 2004 Boon did mine,and the only thing better then this mod was his turn around time.He had it shipped back out to me the same day he got it. Try to get that kind of service from Trinity!!! Quote Link to comment Share on other sites More sharing options...
DIRTMAN350 Posted April 12, 2004 Report Share Posted April 12, 2004 Hey sickboy, What type of temp gauge do u have and where can i get one? Thanks Quote Link to comment Share on other sites More sharing options...
BansheeJen Posted April 12, 2004 Report Share Posted April 12, 2004 Loved the mod on my banshee! Big difference to me in the revs. Much faster and responsive. Cost me about $45 to get it done. Only difference I noticed that took some adjustment to my riding style was as fast as it revs it equally falls as fast, so before when I could dive into a corner and jab the brakes to seing around and it worked fine. Now I have towatch how hard I jab or it'll stall the bike, use the clutch a little more now in tight turns than before is all. I've adjusted to the flywheel and dont even notice it now inthe turns.

boonman Posted April 13, 2004 Report Share Posted April 13, 2004 Jen, I've never heard of such things. 9 times out of 10, with a lightened flywheel, you should be able to "snap" out of the corner easier, because of the less rotating mass, the RPM's pick up instantly. It should actually help you in the corners. I know it helped my bike's response. It is insane. You want it, it's there... Perhaps you are in too high of a gear??? I don't know.... I did notice that in TT, It lights up VERY quickly coming out of the corner..... Quote Link to comment Share on other sites More sharing options...
dcmoose Posted April 13, 2004 Report Share Posted April 13, 2004 this might sound silly. what about balancing. will you feel vibration due to uneven material removal. i had a cr500 motor in a 250r frame and it rattled like a bitch, and i know this is because it had no counter balancer, but wouldn't a out of balance flywheel casue the same thing.

boonman Posted April 13, 2004 Report Share Posted April 13, 2004 Nope. They are balanced at the factory. And the jig and fixturing I have, mimics perfectly the end of the crank. When the flywheel is bolted to the jig, there is no runout. The material is removed in a perfect circle, so there is no "uneven" material removed. This is however, assuming you don't bend the flywheel by using a 3-jaw puller..... Quote Link to comment Share on other sites More sharing options...
Cotton eyed Joe Posted April 13, 2004 Report Share Posted April 13, 2004 Who rides a shee at such a low rpm that it's going to stall. Its funny to watch someone that hasn't ridden one or that is used to riding 4 strokes. BZzzzz clunk. Quote Link to comment Share on other sites More sharing options...

BansheeJen Posted April 13, 2004 Report Share Posted April 13, 2004 It does snap out of the turns. But before when you came in to a tight turn in the woods pretty hot you could jab the brakes and spin around. Now i get a little jab happy or jab um too hard and I stalled it a few times when I first got the flywheel on. It seemed more prone to less mass falling off of the RPM's faster than the original mass of the flywheel. There's quite a bit of difference in the turns on a TT track, and the tight knit woods we ride in. All in all I love it even in woods riding it just took a bit of rider adjustment to know how the shee reacted to the flywheel. Good investment all in all!
