[QUOTE="AJSB, post: 25416, member: 22207"] Hi, This is my 1st post at DRN i hope that you can help me out... I started riding with 2S (only with 50cc but very agressive engines because of 24mm carbs and narrow power band) then i jumped to 4S with a DR350s (IMHO, a complete POS) and then my current bike (LC4 620 with a 195 main jet !). The thing is that now i getting tired to ride in mud or tight terrain a bike that weights 140Kg with fuel tank full ! Sure, there are the new gen 4S like the 520exc, FE650e, TE570, etc,etc. but i noticed that those new gen 4S are a ***** in the maintnance chapter ! 10 hours for a oil & filter change, 20 hours for valve adjust with usualy dificult access or expensive alu. "tablets" for valve adjust, etc. !!!...and i bet that their pistons,etc. are way more expensive than of a 2S ! Some even use titanium valves ! I dont even want to think what will be the price of that s**t if the camshaft chain breaks :-( also, those engines are so squeesed in the frames that for a piston replacement you need to remove the (still heavy) engine from the frame ! etc,etc. I dont know but current 2S seem reliable (correct me if im wrong) and the maintnance is more simpler and relaxed (at least for me even a piston replacement in a 2S is more relaxed than a valve adjustment in a 4...i done both no mather i dont touch a 2S engine a long time now :- ) and AFAIK, i dont even need to remove the engine to replace the piston ! New Gen 4S ? I guess not for me ! So, what im looking is for a 2S with a good power band w/o too much hit or need for clutch *abuse* (because of my 15/40 gearing, in muddy/tight terrain i need to make some more than usual use the clutch of my LC4... still good after 21000km...i dont mind to use a little more the clutch...i just dont want to use it as a 125 2S MX bike needs to. In special i like your opinions about the following models: KTM 200/300/380exc. Husky wr125/250. GasGas ec250/300. (FWIW...not that im thinking doing much of it with them but its nice to go from a trail to other...all of them are street legal in Portugal :-) Just to have am overall big picture of each brand... OEM piston and rings prices in your Country ? Parts avaiability in your Country ? ...and, can i remove their cylinders w/o remove the engine ? I my area no one ride one of the above models so i didnt check... PS: i hope that the REV! do it well and give a new hope for the future of 2S. These new 4S also make a lot of noise in special Yams...damn 747_NOISE_level on 2 wheels :-( TIA ------------------ Amandio J.S. Bacalhau < '96 KTM LC4 620 > [/QUOTE]
