My friend just bought a very low hour, unraced 00' 400 SX. He rides tight woods, and found the bike overheats and the over flow burps onto the exhaust when he rides slow through the tecnical stuff. . Kinda messy. He has installed DEVOL rad guards, and is about to get some REDLINE coolant wetter, which will hopefully help with the over heating. He wants to run the bike without the T-Stat but I told him not to, you will get hot spots in the engine and possibly damage it. Are there any other suggestions he could possibly do? Like removing the rad guards, as they restrict the air flow thru the rads?
Also he is finding the bike does not have smooth clutch engagement, When he releases the clutch the bike sorta wants to lurch ahead. Maybe the 4 speed tranny i guess. The bike has a 14T front sprocket and a 52T rear. It is geared down but not enough. Would it be safe to run a 12T on the front or is this sprocket to small for the power of the bike.
And another question! HE was also wondering about using Stainless steel oil filters because the previous owner told him to change the oil and the oil filters approx every 4-6 hours of riding time. THAT can get expensive! are there any draw backs using the stainless steel oil filters?
Any input would be very appreciated. I just dont want him to be dissapointed with his first KTM and it will not work for him for the type of riding he does.
Thanks again
