cowpuc Posted March 31, 2015 Share #53 Posted March 31, 2015 Now that we are all back on the subject of removing ruined carb kibbles and bits, and while we are waiting for Cha to give those measurements, I will tell you all a story.. Back in 1991 a young guy brought an 89 CR500 Honda into my shop to trade it in on KX250.. I had ran CR500's for many years and gotta say - this bike looked BRAND NEW!! While we were standing in the parking lot looking at the CR in the back of his truck I had to ask him why he was swapping it in.. Expecting him to say, it flipped on me the first and only time I ever rode it, I was actually shocked to hear him say that he could NEVER get it to start - they can be hard starters, especially when they get miles on em but this thing looked BRAND NEW!! The glare in his eyes told me he was not joking!! He said (and his title proved it) that right from brand new (he indeed had purchased it new) it was THE hardest starting bike he and his friends had ever experienced. The bike looked like it had less than 5 hours of run time on it.. I asked him why he didnt take it right back to the Honda shop when he got it home a little over a year ago and found out that it had a problem - they had told him NO warranty.. After making the deal and everyone was gone home, I tossed on my MX boots, tipped the CR down on its side till I got fuel out of the overflow (old trick), lifted the choke - rolled that great big coffee can of a piston around to TDC, gave er solid stiff legged whop and got one "bang" out of it,, hmmmm.. My first thought was she had popped a crank seal real early in life on a backfire and was sucking air.. I gave her a couple tea spoons of mix in the jug, tapped her again and she started right up but strangely died after the fuel ran out.. Float bowl read full.. Pulled the main jet screw out of the bowl and the main, spotless as was the rest of the carb both internally and externally - looked like brand new.. Playing around firing it up a few more times on premix raw fuel (it ran great as long as you primed it) it suddenly dawned on me that the enrichment system on the carb was not functioning.. Honda used a lot of Keihin Carbs through the years and this particular Keihin had a choke knob on the left hand side that you lifted up on to choke the carb, this "arm" also served as a low speed idle jet that you adjusted by screwing it in or out to set idle. I removed the arm and could not believe what I found, the tiny little tit on the end of the shaft (looked almost identical to the pictures here of the end of the pilot screw) had broken off and was lodged in its tiny orfice - perfectly blocking fuel from entering the choke circuitry when the chock lever was lifted!! I surmised that the lever was broken from brand new and that the young man who swapped the bike in had been trying to cold start a CR500 Honda with NO choke for all its life - kids right leg is still probably twice the size as his left!! A few days later the young man was back at the shop to purchase gear or something, I took him in the back room, did a one kick start on the bike for him, told him what I found and offered him his bike back - he laughed and said he had had enough of that (he said a bad word here)... Someone hand me the marshmellows will ya... Link to comment Share on other sites More sharing options...
Chaharly Posted March 31, 2015 Author Share #54 Posted March 31, 2015 Well @dingy, I didn't get your measurements, but I got something better... Pictures! (Maybe they're not better) [ATTACH=CONFIG]98465[/ATTACH][ATTACH=CONFIG]98466[/ATTACH][ATTACH=CONFIG]98467[/ATTACH] Yeah, what I did was drilled too far, well past the head. I had completely removed The head and didn't bugger up the threads, Thanks for the suggestion by the way with the torx bit! Worked perfectly, just my error of drilling too far. So basically all I had to do was get the rets of the bits out. So I just took a teeny tiiiny drill bit, don't remember which one and drilled into the stem with a little pressure, and just pulled the rest out. [ATTACH=CONFIG]98468[/ATTACH][ATTACH=CONFIG]98469[/ATTACH] So I got the new one in, and its running great. Totally happy with it! I just wanted to say thanks for all the advice guys its really much appreciated it. If I didn't bugger it up so bad at first It wouldn't have been a big deal, but I got it out! What do you guys think of the temp gauge by the w Link to comment Share on other sites More sharing options...
Marcarl Posted March 31, 2015 Share #55 Posted March 31, 2015 Those gauges are all different,. The only way to know for sure what the temp is you need to check it with an infrared gauge. Mine used to run on cold until the weather really got warm and the fan would lick in just before the red,,,, but like I said, they're all different.
