philswiv Posted March 2, 2005 Report Share Posted March 2, 2005 Hi Folks, A bloke asked me the other day if my '97 Techno still had it's fly wheel weights on it. Why wouldn't it have? Is there any point in removing them? If so, why were they put there in the first place? I would imagine that if I was to find 'em and try to remove 'em that they'd be under the right hand side engine cover behind the fly wheel? This would mean I need a fly wheel puller, right? Can anyone shed any light on why/where/what and how on this subject? Cheers, PhilSwiv . Quote Link to comment Share on other sites More sharing options...
richywrecka Posted March 2, 2005 Report Share Posted March 2, 2005 Easiest way to explain it is the weights help the generated force centrifugally, in laymans terms it keeps the revs going without labouring the engine to much. Motocrossers dont have the weights because they use higher revs for a more sustained period. It a bit basic but if you took the weights out you would notice the revs dying out quicker on climbs. Hope this helps a bit. Quote Link to comment Share on other sites More sharing options...
bob Posted March 2, 2005 Report Share Posted March 2, 2005 I don't know exactly where the flywheel weights are but I think you are right but you may not need a flywheel puller as they may just be bolted onto the outside. The point of weighting the flywheel is to make the engine more difficult to stall and have smoother accelleration. Some people take the weights off (especially on Betas) in order to get a faster revving engine for rock steps and stuff where that little bit more zip is needed. But In my opinion removing the flywheel weights is no advantage because it means that as soon as you hit the slippy stuff the engine accelerates too quickly and you lose grip much more easily . It is up to you and you can try it without the weights on, it will run fine, but you will probably just be bolting them back on as soon as you realise how it is crap on mud.

I removed the weight off mine last year and also added a fast action throttle and a softer carb-slide spring - so my bike should be *really ****** in the mud, but it isn't. In fact my results haven't gone down at all. They haven't gone up either but... Quote Link to comment Share on other sites More sharing options...
bob Posted March 2, 2005 Report Share Posted March 2, 2005 oooh, I well i suppose it depemds what youre into. EVERYONE has told me this so I just presumed it to be correct and I like my bike as it is, so it is gonna stay that way,plus I am very light so I probaby would get really stuck in the mud if I can't keep enough weight on the drive wheel to handle the extra zip. Is it worth the effort? Quote Link to comment Share on other sites More sharing options...
stevel Posted March 2, 2005 Report Share Posted March 2, 2005 If the techno weights are the same as a Rev 3 then they are just screwed to the outside of the flywheel, and can be removed/ replaced in minutes. As everyone says the flywheel is there to provide inertia, and the heavier it is the greater the inertia. The downside of that is that although it will be harder to slow the flywheel down it will also be harder to get up to speed. If you like your bike more docile then stick with the weights, if you prefer it to be zippier, take them off. If it is as easy to do on the Techno as the Rev 3, take them off , try it and if you don't like it put them back on. As the saying goes 'Nothing ventured - nothing gained' Quote Link to comment Share on other sites More sharing options...
neonsurge Posted March 3, 2005 Report Share Posted March 3, 2005 My Rev3 came with a flywheel weight (unfitted) and quick action throttle. Loads of zip, very fun to ride but completely useless in the kind of tight, very slow sections we tend to get 'round here. It was difficult to find traction and the engine stalled very easily. It might have been OK for an expert level rider but just didn't work for me. I put the weight on (2-minute job) and changed the throttle and I now have a more controllable bike. Mt results haven't improved significantly but I'm fiving for different reasons now! Quote Link to comment Share on other sites More sharing options...

Is that because you are usually too busy laughing at me throwing myself off the tallest thing i can find ! Quote Link to comment Share on other sites More sharing options...
