Howdy all!
Finally made it here. I have been looking at bikes for 2 years on Craigslist and dreaming but found one in my budget. I have had my 66cc gas bike for a year or so now, and it just made me want to get a motorcycle even more. (pictures at the bottom.)I am new to street-legal motorcycles and just purchased a Gen 1 KLR 650. The bike has 16000 miles on it and PO kept a nice chart of all the upgrades and mods he did to it. He gave me all the original parts and also provided me with the manual and toolset.
He has done the Doohickey, KLX Jet, Subframe Bolts, rebuilt piston and cylinder, Mikuni TM42 Carb, Thermobob, and new radiator hoses. He also upgraded the rear spring and the front brakes. I saw this bike on Cycletrader for a decent bike jumped the gun and bought it. I am very happy with my purchase and I think that it is a sweet KLR with a lot of mods already done to it. Here is a picture.
Now onto the bad news. I trusted my friend who rides a Rebel 250 and a CBR600rr to come with me and test ride the bike. (I do not have my endorsement yet.) I figured he knew more about motorcycles me and would be able to provide some sound advice. Anyways, I let him convince me to let ride the bike all the way back to our city, (I know this was a very dumb mistake) and it overheated and died on the way back. The bike died about 130 mi into the trip. (still won't turn on) He noticed that the temperature gauge was in the red, but did not think that it was a problem because his bike that he rides feels way hotter. When I checked the oil gauge it was very low, also the coolent was very low. When I checked the bike before the purchase, coolent was full, and oil was full. I am sure that it was running rich and buring oil. I went against my better judgement when I let him ride it and its my fault. Sucks to learn things the hard way.
Here is a picture of the rock that I used to get the bike in the bed of my truck.
I am determined to fix this bike. The bike turns over. Has spark, fuel, and air. But the bike is making low compression, even with the KACR disabled.
I have replaced the oil, spark plug, and coolant. I just attached an air compressor to the engine and it is leaking out of the tailpipe when at the top dead center. I think the signs are pointing to a valve being warped or broken. I have not had the time or the space in my apt. to look at the piston yet, but I will soon. I am also considering the 685 kits because if I have to tear down the entire engine, I might as well build it back better. I know that PO already rebuilt the engine. I looking forward to adventure riding this bike. KLR is a good bike for me because it is very capable, and I will get to experience all the aspects of motorcycling. I want to go on some do some dual sport adventures in Texas once I fix this thing. I am nervous to take apart the engine but I am pretty handy and have an automotive tool set, the tools the bike came with, and the manual. I know this bike is supposed to be bulletproof, but everything has its limit.
Now for the questions.
Good machine shop recommendations in Houston?
How much does it usually cost for a mechanic to do a leak-down test?/Is it worth it for the bike to be diagnosed by a proper mechanic?
705 kit vs 685 kit?
Engine teardown tips?
Here is the 66cc gas bike I put together.
If anyone else rides these in the houston area we should get together and maybe host a race/show off day.
TLDR
New KLR650A 2000. Overheated. Tips on rebuilding it. GasBike
