Guest rockmeupto125 Posted June 5, 2005 Share Posted June 5, 2005 Gentleman on the European forum claims a significant vibration in the right footpeg and bars, increasing since he bought the bike used with very low miles. 2003 model as I recall, and he states that it is directly related to engine speed. Any thoughts at all? Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted June 5, 2005 Share Posted June 5, 2005 Previous owner took out both balancers for more BHP? Quote Link to comment Share on other sites More sharing options...
XXTi Posted June 6, 2005 Share Posted June 6, 2005 Dave was talking about this at MegaXX. He said his bike vibrates in a certain RPM range too. He also said several guys on the European forums were reporting the same thing. I never heard of a 'Bird vibrating before he mentioned it.

Hobicus Posted June 6, 2005 Share Posted June 6, 2005 Yep, Davesxx01 has the same complaint. Quote Link to comment Share on other sites More sharing options...
cbrxxquad Posted June 6, 2005 Share Posted June 6, 2005 the balancers can be off a tooth at the timing marks and will vibrate doesnt take as much as it should to get them out of time or a dirty injector Quote Link to comment Share on other sites More sharing options...
XX4me Posted June 6, 2005 Share Posted June 6, 2005 So it's only while underway? Seems like I remember Daves being in the motor. I'd be more inclined to believe there was a problem in the crank itself causing the excess vibration. I have a Falicon Super Crank in my bike. http://www.faliconcranks.com/crankwk.htm It has been lightened considerably compared to stock and I still use the stock counter-balancers with no noticable increase in vibration from the motor at cruising speed. According to the guys at Falicon this is due to the fact the counter-balancers are more to dampen the vibration from the mass of the pistons moving up and down than the crankshaft.

molson309 Posted June 6, 2005 Share Posted June 6, 2005 Incorrect chain tension can cause this - I overtightened the chain on my VFR and got vibration at certain speeds. I backed off the tension and the vibration was gone. I've been careful with chain tension on the Bird and haven't run into this. Quote Link to comment Share on other sites More sharing options...
cbrxxquad Posted June 6, 2005 Share Posted June 6, 2005 i wonder about the rubbers in the counter-balancers too Quote Link to comment Share on other sites More sharing options...
azxx Posted June 6, 2005 Share Posted June 6, 2005 Maybe check engine mount bolts retorque, loosen and reposition exaust, adj. balancers. It helped on my buzz bomb Suzuki GS1150ES no balancers in it but it sure needed them. Quote Link to comment Share on other sites More sharing options...
Rider99XX Posted June 7, 2005 Share Posted June 7, 2005 My XX developed a very slight vibe/buzzy feeling in the right grip and left footpeg between 40/50 mph. Doesn't seem to be rpm related. I checked everything that could be tightened, everything was tight. I know I need steering head bearings, those are on order. New fork seals and new fork oil goes in tomarrow. The seals on the front wheel are somewhat dry rotted so a bearing and seal job are in the near future. There is no descernable side to side movement in the front wheel nor is there any tight/rough spots when you spin the wheel. So to comfort my feeble mind I'm going to install new bearings. Maybe that will help but if it doesn't it's no big deal, the vibe is hardly noticeable. Quote Link to comment Share on other sites More sharing options...
