I'm looking for the correct valve clearance specs for a 2014 xf250. I've been searching around and finding all different numbers. I have a loud tapping noise that sounds to be coming from the valves once warm. I'd like to check and adjust the valves first before driving myself crazy. I've also heard that these motors are notoriously noisy. Can anyone that has one give me some input please. Thanks.
Similar to TU250:
IN 0.03-0.08mm (Just tune to 0.002)
Ex 0.08-0.13mm (Just tune to 0.004)

Which oil is on the bike? Some are not good enough in air cooled bike
I was given specs of .05 ~.07 intake and exhaust by the factory, but then again every Chinese motorcycle producer I've ever asked about valves has given me the exact same number. Humanbeing is right, follow the specs for the TU250, these engines are more or less identical.
I had two of these that you can read about here, I never felt the engine was excessively noisy, but they are a single cylinder air cooled engine and the giant fins on the head of the 250 seem to resonate engine noise.
Thanks for the replies. I'm going to check and adjust the valves tomorrow. I just changed out the break in oil over the weekend and it made little difference in the noise. I used Mobil 1 4t 10w40. If the valves don't take care of it I'll have to go back to the dealer...
Adjusted the valves to .002 and .004 , they were a little wide. It sounds better, but there is still some noise when warmed up. Not sure how much noise would be considered normal for this motor...
Record an audio sample. I'm curious.Quote:

Just got a call back from dealer. They also were given .003 intake and .005 exhaust.
What oil has anyone used in this motor? Currently has Mobil 1 4t 10w40. They also have a 20w50. Thoughts?
You do know the #1 rule on every motorcycle forum in the world is not to ask the "what oil" question? :naughty: Read your owners manual and adjust for local temp conditions.Quote:

Everything else is complete crap and spending anything less than $18 for a liter of oil is just being cheap. Spectro Platinum 4 Full Synthetic is the best oil in the world and anyone that disagrees with me is wrong.

Cheers!
Your choice of oil China-V is a very good choice !! So I for one will not argue that point !
But what I would argue is with a cheap Chinese made shit engine as most are would you benefit with the use of such a good
Brand of oil !!! IMO cooking oil would do the same job and cost a lot less as the old saying goes "you can't polish a turd "
Corn oil burns above 350 and most engines run at about 225 degrees F, LOL anybody ever researched what synthetic oil is made from.

ChinaV thanks for your reply. I haven't ever used Spectro oil, I will look into them. For my current temperature range many oils will work. I tried switching to a 20w50 and it sounds about the same. Looks like it will be headed back to the dealer shortly. I understand it is a "cheap" motorcycle and my expectations weren't set too high, but they have already been exceeded everywhere else on the bike, other then the tapping. I wanted to buy this bike to get a taste of dual sport riding before spending a ton more money on a bike that would just sit there and collect dust.
"Bel Ray" and "Bardahl"?
I also use belray thumper oil for my ssr xf250gy also known as pulse adrenaline 250 if you need parts for this bike chinesemotorcyclepartsonline is a great site with all the parts shipping is pretty quick to the us I live in ohio and it does not take long to get the parts. you can also look on ebay many chinese parts can fit this bike such as the cheap chinese rear master cylinders on the chinesemotorcycleparts site its like 75 bucks but I bought the cheap 10 dollar one on ebay instead just an fyi
