thesaint Posted September 3, 2015 Report Share Posted September 3, 2015 (edited) Any here that knows why the cylinder on my bike is casted R37 and have the number 56 stamped to it? Is these numbers someting i need when ordering a new piston and piston rings? See the picture below I also wonder if i have placed the lower radiator bracket in the right location closest to the cylinder See the picture furthest down Edited September 3, 2015 by thesaint Quote Link to comment Share on other sites More sharing options...
lineaway Posted September 3, 2015 Report Share Posted September 3, 2015 The R37 is probably from the new JTR370 cylinder in `96. Quote Link to comment Share on other sites More sharing options...
crazybond700 Posted September 3, 2015 Report Share Posted September 3, 2015 (edited) I dont know. I think R37 is the type or something, have seen it before. Will look if its on others aswell for you tomorow. /lineaway make sense, although I though those has also 370 on the bottom of the cilinder edge.

bartman6996 Posted September 3, 2015 Report Share Posted September 3, 2015 (edited) R37 could well be the generic number for a particular engine type. 56 could well be the inline inspectors number after checking manufacture process?? Its cos I'm an enjineeer im afraid.............. Edited September 3, 2015 by bartman6996 Quote Link to comment Share on other sites More sharing options...
thesaint Posted September 3, 2015 Author Report Share Posted September 3, 2015 (edited) Meaning that there was a new cylinder for Gas Gas bikes made from 1996? Even my bike is from 1998 but it still have the new cylinder that came in 1996? When i have been looking at piston rings and pistons online i have seen piston rings and pistons described as type L and i must admit that it does not tell me much Anybody knows where they sell fan motors for a "nice" price like the one on the picture below The motor must have the threaded axle for the fan blade which is fastened with a nut and also the "ears" that is used to attach the fan. Also attached with 3 small screws Edited September 3, 2015 by thesaint Quote Link to comment Share on other sites More sharing options...

When i have been looking at piston rings and pistons online i have seen piston rings and pistons described as type L and i must admit that it does not tell me much LType piston ring has to do with the shape of the ring, if you look from it from the side (crosssection). An L shape is well, L shaped Actually an L on its side. Edited September 3, 2015 by crazybond700 Quote Link to comment Share on other sites More sharing options...
thesaint Posted September 3, 2015 Author Report Share Posted September 3, 2015 I found a place in germany that have the cylinder and piston rings with the correct part numbers for my bike and those parts is type L I was able to get hold of a big "Jumbo" tank for my bike so now i can fill 1 more litre of fuel I had a company that makes decals making some original looking Gas Gas TX 320 decals for me So i only need to put on new TX 320 stickers on the big fuel tank(i will put new decals on the original small fuel tank as well) So if any here need decals they can make them for you.

tony27 Posted September 3, 2015 Report Share Posted September 3, 2015 Fan motor is fairly common on older Japanese road bikes, the 1 I used came off a Honda VT250 from a wrecker, had to change the plug which also got rid of an extra earth wire Quote Link to comment Share on other sites More sharing options...

mcman56 Posted September 4, 2015 Report Share Posted September 4, 2015 The R37 may be a casting number used by the manufacturer who cast the cylinder. Rev3s have a 2 digit cast number that appears to represent the year the casting mold was made. They tend to show a number 1 or 2 years older than the bike. It probably depends on how quickly a cylinder can go from making the mold to getting delivered on a bike plus what ever inventory is held.
