ive got an 08 250 with about 21000 miles on it here lately there has been lots of noise around chain and sprocket area and i feel slight vibrations when riding im not a mechainical person at all, any suggestions

kkim · June 14th, 2009, 10:21 AM

when was the last time you clean, lubed and adjusted the chain?

miniguns167 · June 14th, 2009, 10:27 AM

lubed last week but have never cleaned chain and this chain has about 4000 miles on it what amount of tension am i suppossed to have on chain

kkim · June 14th, 2009, 10:34 AM

the correct amount is listed in your owner's manual. how to do it has been recently explained very well by member "banzai"... do a search and read what he had to say on this subject.

welcome to the site.

Click here for the thread on chain tension tools and other good info

Might want to remove the rear tire and check the sprocket hub, cush drive, and bearing as well. Since the sprocket drive has a non-sealed bearing, it needs to be inspected and periodically re greased, especially if chain tension is kept on the tight side of the spec.

Just wondering, why was the chain replaced 4K miles ago? With proper tension and service a drive chain will last almost the lifetime of the bike. Also, unless they're in pristine condition, front and rear sprockets should be changed when a chain is changed to make a matched set and ensure that any wear on any old item does not induce early failure into the new items.

thanks for all the info ill give it all a try, i had to replace the chain and sprokets at around 17000 miles i ride in alot of rain and was ignorant with the upkeep on the chain so it was pretty messed up so i just had it all replaced, it was my only transportation and going to work sometimes 100 miles one way didnt leave me anytime for upkeep

kkim · June 14th, 2009, 01:09 PM

jd, motorcycle chain maintenance is pretty routine and cleaning and lubing should be done every 400 miles and checking adjustment every 600.

how many miles do you ave on the bike now and have you had the valves checked/adjusted? when's the last time you did an oil change?

good to see the little ninjette being put to good use.

maintenance schedule is here...

it has alittle over 21,000 miles on it and i ride it hard, never had valves checked but do change the oil about every 4000 miles

kkim · June 14th, 2009, 04:06 PM

you should consider having the valves at least checked as you should be coming up on the 3rd valve inspection/adjustment soon.

valve clearance inspections should be every 7.5K miles. loose valves can be bad for gas mileage/power, tight valves are very bad for the engine.

miniguns167 · June 14th, 2009, 04:13 PM

ill be sure to get on that, all the shops around my area stay slam full and want to hold bikes for atleast a month or two, it drives me crazy thanks for the info that is most likely why my mpg has gotten so bad

JD, if you don't want to take it to a shop and are really confident in your abilities, Vex posted a DIY on this:

I had noticed that, but figured he might be able to find a friend or something that could help as an alternative to leaving it for a long time

backinthesaddleagain · June 14th, 2009, 07:26 PM

good amount of miles for sure. how are other things holding up, clutch, wheel bearings, suspension?

miniguns167 · June 20th, 2009, 10:16 AM

well i removed rear tire and checked bearings, they are fine, i cleaned and lubed and adjusted the chain to proper tension, i gave it a good look over and found a nut off on one of the bolts that looks to be holding on the swing arm, the bolt was so loose that i was able to push it out with my finger, i got a new nut and fixed that(wow guess what, that stopped all the shaking) and bike is running great now. about valve adjustments, thats way to complex for me. thanks to all for the info, just knowing that there is a site out there that will help peps who need to get info is a relief.

kkim · June 20th, 2009, 10:18 AM

can you get a pic of which bolt was loose?

miniguns167 · June 20th, 2009, 10:22 AM

my bad it looks to be holding the exhast muffler on, but the bolt runs diretly behind the oil sight glass and is about 5 inches long

kkim · June 20th, 2009, 10:27 AM

which one?

miniguns167 · June 20th, 2009, 07:15 PM

its about an inch below the sight glass for oil level and toward the inside of the frame , from the pic u posted that would be the nut side on my bike
