Bad bog at ½ throttle
Posted: 10:24 am Jun 18 2010
I finally got around to taking the carburetor apart last night to see what condition it was in. I’m very pleased to say it is spotless! I haven’t seen too many carbs but this one is clean. I pulled the jets and my main is a 160 and the primary is a 48. The needle is an R1174K (2AFKQ) with the clip in the middle position and the AS was just under 1 turn out. I wasn’t able to measure the float height as I’m not sure what I need to buy to measure it with.
I am assuming these are the stock jets and needle.
I changed the transmission fluid and took it for a ride in the field behind my house. The first two passes were fine, but each pass after that I got a huge bog (to the point the engine would almost stall) when I gave it more than ¼ throttle. I stalled out after the 4th pass. Took it home and re-checked the oil level in the tranny and it was completely covering the sight window, so I drained enough out to get it between the lines. I haven’t ridden it since to know if that helped or might have been the problem.
Two questions:
First, could the overfilled transmission cause a bog like I described? The manual made mention something to that effect.
Second, I’ve read Indawoods jetting sticky about 10 times…and it’s finally starting to sink in, but I’d like to know if my current jets could also be a part of the bogging. When I test rode the bike it didn’t do this. If not, do the jets and AS setting seem like a good starting point? The bike did seem to run rich prior to doing any work. If nothing seems too far out of wack, I’ll just do what Indawoods suggests.
Thanks for any suggestions! BTW, I’m in DFW, TX riding a bone stock ’05 KDX 200.
