Yes the oil filters are pricey for these bike. I bought a bunch from the dealer when the bike was new. I have run out and need to order some more. I saw them in bulk on Amazon for much cheaper. Search for the Suzuki tu250 filter.

For jets people say to try RockymountainATV.com and order the Mikuni N102/221 Series jets. Sigma-6 jets makes a jet kit for this bike that goes for $39 on ebay.

I haven't really had to order too many parts for the xf250, but the timing chain broke on it and right now I am waiting to see if SSR will honor the warranty. They have made the warranty process very difficult.

Otherwise I have really enjoyed the bike. I was getting about 81mpg before the timing chain popped. My bike has about 2,500 miles and the piston looks brand new. I'm not sure what could be causing the carbon build up. Are you using 91 octane? Overheating maybe since it's lean? That may be worth starting a new thread on in the dual sport section.

It has been a fun bike.

Have you ever found any jets for the Carb on these bikes? I have been ordering parts from the UK for the pulse adrenaline bike they have over there is the same bike but still dont know what kind of jets or where to get them for this carb my bike runs lean and would like to richen it up some w different jet. if you need parts http://www.chinesemotorcyclepartsonline.co.uk is a good place for most parts but some the shipping is to high but most parts shipping is good.

Hello, I have the same bike as you SSR XF250GY and was wondering what you have found about it such as where you get parts? I just ordered a kn136 oil filter hoping it is the right one due to the amount ssr charges for a filter lol. I noticed today when i was checking my valve clearances there is much carbon on my piston and the bike is still new barely even 600 miles on it. I took petcock off cleaned screen it had many pieces of rust on it and the rust specs got in my carb vent lines and gas line took me two days to fix that problem. Just figured I would message you since I dont see many people with this same bike would be nice to exchange info.
