2010年2月16日 · Hello all! For those of you lucky people out there to own arguably the most superior motorcycle ever , I'm sure you have at one time wanted to find a safehaven where you can share your XT550 stories, what companies still make mod parts for this bike, what you can customize or swap from different bikes, and general information that may be somewhat hard to find without calling your local ...

2009年6月19日 · An older friend of mine from work has a 1983 XT550 that he hasn't really touched in quite a few years sitting in his garage. He hasn't kicked it over in probably a year or so, but said it used to run the last time he tried to start it. I guess it hasn't been ridden in over 3 or 4 years though, an...

2003年10月9日 · As stated previously, this was the first of the 4 valver singles that Yamaha produced. The second bite, the XT600, was the bike that the XT550 shouild have been. But they are still a good bike regardless, just of a certain era. Oh, and with most Yamaha XT's, the motors go soft and gutless due to the compression rings wearing out fast.

2009年1月11日 · I bought an '82 Yamaha XT550 yesterday. I'm more of a two-stroke guy myself but finding decent two stroke dual sports is difficult to say the least. I had a '74 Kawi F11 250 for a while but the thing was a dog. Have a '79 CR250 Elsinore I ride now and again but it's an aggrivation because in NJ t...

2010年8月16日 · -the biggest displacement that can a xt550-600 is 686 with wiseco piston-stock xt550 cylinder can be bored to 605-610cc 95.9mm. for more CC than 610 you must add a xt600 cylinder. DON'T put TTR-XT600 head because xt550 has the bigger valves-a good xt550 engine can rich 70hp 686cc-fcr35x2-carillo rod-titanium valves and springs and drivers...

2009年7月29日 · The stock XT550 timing curve advances from 1250 rpm to 4000 rpm and then starts to retard at 4000. This just seems so wrong. I understand why they did it. To make the bike start to feel sluggish up top and make people change gears. You opned a new can of worms and issues with air box/filter with the Banshee carbs, interesting you chose those ...

2011年4月22日 · YZ has had disk brakes for a long, long time, longer than the XT550 has been around, IIRC. Mind posting a photo? ETA: my bad, YZ's got the front disk in 1985, in 84 there was only a YZ80 (at least according to my semi-complete parts reference), in 82 the YZ80-250 were drum brakes. Still, a photo would help. In stock form, it's a darn tall bike.

2010年8月31日 · Unfortunately the xt550 needle valve and gaskets i ordered off Ebay were incorrect. WORDS OF ADVICE watch the ECONO CARB KIT from Sirius Consolidated on Ebay - i haven't spoken with them yet but what they sent me didn't even match the picture on Ebay.- so I made my own gaskets instead and the needle valve appeared to work well when tested so i ...

2016年4月25日 · If this works this gives XT550 users much more confidence in longevity of our bikes. Best part is its only 20 bucks for 2 pickups and making a bracket from scrap metal I count as free. If anyone has any input or ideas please let me know.

2014年10月31日 · I just picked up a 1983 XT550 and plan on going through and cleaning it up over the winter. starts and runs great... until about 4000 RPM the engine cuts off. It seems like it is losing fuel. I pulled the carb (YDIS Y26PV dual carb - which I've heard can be a mess) and cleaned it up. There was a little debris in the bowl and the needle jet in ...
