  1. Moses, Thanks for the response. I'm in Michigan now, I'm not sure how the folks in this area value these incredible bikes. I'm not in a hurry to sell, so I'm sure I'll find a worthwhile buyer. Thanks for the good word on the value of these cycles! Costa
  2. Hey Gents, I've been meaning to get back to you guys with some results... A local shop re-built the head completely and I installed a stage 2 hot cam. I set the lashes for the new cam and reassembled the bike (new top end and cylinder also). After a break in and then about 150 miles I noticed the intake rocker shaft (visible from the exterior left side of the motor) had some rotational movement. I sent a video over to the shop that built the head and they wanted to take a look. After their disassembly and inspection they said their work was done correctly and my work was done correctly, but the top end is smoked (cam is done, and rockers are done and worn). They said lack of lubrication. So thats where I'm at! Might have to sell the bike for cheap. Hope you guys are well, Costa
  3. Hey Moses, It looks like it's been about a year since you visited this forum of yours -- I found the information discussed here super helpful. I've wanted an XR650r since I was 14 years old. Dust to Glory is still my favorite. I am walking in your exact xr650r steps. I just bought an Australian 2000 xr650r from an honest seller who I spend tons of time with talking about the bike. The bike I am most familiar with is my 2004 cr250r that has been built head to toe for the desert (I'm obsessed with Utah). I heard a lot of "rolling" noise in the top end of the bike (especially with my helmet on). Being unfamiliar with 4-strokes I bought the bike for a fair price. It's super clean; I just figured the rolling noise was inherent (the piston is like a Folgers can for God's sake). I promised to check the valve lashes before riding it. Before I get into this, I must say that the bike ran GREAT when I rode it... a monster! Australian Model is a pure breed (aside from that lean main jet you were talking about). I pulled the valve check covers off to check clearances. Hmmm, no clearance IN or EX... worried. It had a K&N air filter on it.... I pulled the filter off in the light and I just about passed out. It was like a dirt wind tunnel. One thing led to the next I had the motor out of the bike. Cam = done Rockers = done Piston = done Cylinder = done horizontal scoring at the top of EX side Valves = done, packed in and trashed Cam chain and sprockets were worn for typical wear and tear.. Pictures of everything in the link below Needless to say, I'm re-building the head and top-end. For me the next step is prevention. Questions like, "is the oil system working properly?" and, "is the jetting on point?" started popping up.... this is how I found your site. The air filter is the main culprit in my eyes for obvious reasons (the air boot looks like a dirt wind tunnel). The bike is uncorked: open muffler open manifold main = 175 pilot = 65S which is weird needle = 53E on the second to the bottom position I live in good 'ol Colorado. I ride here and as far south as Moab so 3000' to 9000'. I picked up a Stage 1 Hotcam, which will be its only modification besides being uncorked. 175 seems a little fat. My main concern is the motor's safety when I take it to the desert. What main size would you recommend? Should I find a 68S pilot and whats up with my clip position? Probably just the old rider tuning? If you will..can you give me some advice on the following?: What jets would you like me to run? float height options (I have no idea)? should I ditch that darn K&N? What's the most bomber air filter option? I've heard about a needle o-ring, what's the deal with that? Would you recommend it? What plug have you seen work best in this bike over the years? Here are some off topic XR questions: I'm running really wide bars, is it okay that I run the throttle hand grip upside-down to afford me more slack? I'd like to run some strong lighting for night desert riding, what direction would you point me in lighting wise? I'm using the following service manual link. https://goo.gl/0FDef2 I believe it's universal. What do you think and if you think I need to order one, where would you recommend I get a Australian service manual? If you ever want to plan a ride out in the desert, I'd be happy to coordinate. Also, check this out for for an XR650r reference: http://teknikmotorsport.com.au/Honda-XR650R-Suspension-Mods remove choke butterfly and 165 main? huh Photo's of everything here: https://we.tl/klDz7P3CGl Thanks!
