alright.. I have another ?... I am reading the service manual from top to bottom for the Yamaha yp250.. which is same as my linhai... ya know... and it says that for the rear gear oil I should use 10W30... I used a 90W-- actual gear oil in it.. but this was after the problems started... but here's the thing.. when I adjusted the valves correctly I gained 10-15 mph but not all the way back up (went from 35-45 top speed to 45-55 top speed)........ could the gear oil be whats slowing me down now?i am grasping at straws....

yeah.. sometimes the bill is more than the bike is worth. BUT! if the shop cant fix a bike.. then I don't think they should be able to charge.... there has to be some kind of protection on things like that... LIKE say u take you car in for brakes and they change out your motor... then you shouldn't have to pay for a new motor... I know mechanics that are good people... but I also know some scum that will squirt oil on yur rear main seal and tell you that its leaking... wipe off the oil they put on... and slap a fat bill in your hand... I HOPE I CHOSE AN HONEST MECHANIC atleast...

Yes Alleyoop the shop does have it. It seems like a good shop though. They have been in business for a long time and have a lot of mechanics. And yes you are correct! they want to charge for even if they don't fix it! Aggravating!! They have had it for 5 weeks now! I just want to be able to tell them what to check and possibly be wrong. They mentioned last time I spoke to them that maybe a new carb might be needed. RRRRRR they are playing a guessing game at my expenses. honestly I might just call it a loss and leave it at the shop!!!! RRRRRRRRRRRR

the shop says that the "tac" for the rpms is kinda jumpy...and may not be reading correctly.. or the cdi box is not always functioning correctly and not giving the bike enough spark.

no it does not climb at all.. dead in water at 4000... weights and variator check out... even the shop took it all apart and cleaned it up... did not help and all looked good.. one more ?... I have had a slight break fluid leak to rear break at engaging handle... could this be the problem? low on fluid= telling computer that break is being applied slightly? or air bubble?
