Being a thumper the P-250 has some vibration at idle,not excessive-seams normal amount and I'm OK with that . What puzzles me is that while sitting still and idling (warming up),but past the fast idle mode, if I apply the rear brake , the vibration seems to intensify (feel through the seat,bars,etc.) This will continue even after a long idle period or even after a couple miles riding-then stop idle-same thing. Now after I have ridden for 8-10 miles this goes away. No seat or bar vibration at idle, (while rear brake applied). Has anyone else experienced this? It not much of a problem, just curious.Otherwise the scooter runs great. ???

HAHAHA....Oh yeah and I torqued every nut and bolt and I couldnt find. It comes and goes
Now that I think about it ,it hasnt happened in a while..It maybe outside temperature related..
The opposite of a cold weather dash board creak..

So, you have looked for where it was comming from too huh? Since you have more milage on your P-250 than I do, I guess I'll just forget about it. If the vibration changes please let me know. Thanks.

Its BACK!!!!
We had a 35 degree drop in temp yesterday and upon start up there it was..Holding the rear brake at idle and a noticable vibration was felt and was seen in the dance the top box did..As usual after a few minutes of riding it was gone..
This has me scratching my head....I can live with the syndrome knowing its just a "this is the way it is thing"..But I need to find out what it is...

Just guessing, but it sounds to me like the engine is running at just the right speed for the cluch to be undecided about whether to engage or not.

GeezerBob has a good point. Try adjusting the idle both a bit slower and higher. See if that affects the vibration.

Ok you guys are making sense...This is obviously when shes off of fast idle.... ill try it later ;)

Found it !! Had the panels off and was doing a valve adjustment, took the torque wrench to every thing in sight..
Front engine mount took nearly a full turn off the torque wrench..Vibration is gone!!!! Cold or warm

Hey thanks Oldbull, I will check mine. But since I'm not due for a valve adjustment,do I need to remove my body panels to get to the front mount? or can I weasel in a socket or wrench? I'm being lazy as I haven't gone out to look for myself. Thanks for any info.

It all has to come off

Hey Oldbull, is the bolt your talking about the front pivot bolt? it has a 14mm bolt head and a 17mm nut. If so mine is tight, but I noticed that this rubber pivot mount (that this bolt goes through) has some flex in it-as I can grab the rear wheel and move side to side the whole engine/trans unit ( very small amount mind you), can't see, it but can feel it at the pivot/frame junction. This doesn't seem right as it would probably want to wallow if pushed hard into a turn. But the bolt is TIGHT. I did not check the other bolts around the various mounting points yet.

Vibration is back..Yes that was the bolt.. GRRRRRRRR
