Hey All you AFers out there,
I bought my AF back in '01 and have have burned a case worth of honda hp2 premix. ( I'd guess about 48 gallons of gas.) I typically ride in tight woods and in a dirty, dusty conditions and I almost never rev it hard. I change my air filter and oil every couple of rides. I have not really noticed any change in power or difference in the sound (i.e., "piston slap").
I figure it might be time to start thinking about a putting a new top end in the beast.
1. Do you guys think I should have probably done this sooner or is now a good time?
2. Are there any tricks to doing a top end in this bike? I know that it is pretty cramped in there with that huge motor stuffed in 250 frame. Will I have to remove the entire engine?
3. What type of piston or piston kit should I get?
4. What else should be done will I have the top end off?
Okay I have a few other unrelated questions about jetting and the rear wheel.
5. What is the stock jetting from the factory?
6. I am pretty sure the stock jetting is a little too rich for my conditions. I have moved the clip postion to the leanest setting and that has helped but I think I should probably change a few needles to get to a more optimal jetting. What jetting would you guys recomend for my riding style at essentially 0-500 elevation with temperature variations from 15-85F, mixing 32:1? (Ohio river valley)
7. The final question is in regards to converting the rear wheel to and 18in wheel so that I can use michelin 140/80-18. Has anybody else used the "bigger" 18 wheels? I feel like that the stock 250 wheels aren't large enough for the 500.:) :)
