got the air box on

Post by Eddie »

well I got the airbox on and what a pain in the butt! compared to the pods the stock box is a pain,(when you are having to take the carbs off for jetting) but the stock box looks way better in my opinion. The bike is still lean so I was looking at replacing the pilots with bigger ones, most of my riding is 1/4 to half throttle i dont really keep her wide open at all, I try to baby her a little. I have the needle clip on the second to last, so I have 1 more postion down and thats it, so Im thinking try one size on the pilot and maybe one size on the jet, but which should i do 1st? it seems im always in the 1/4 to half range on the throttle so its both the pilot and the main, but mostly the pilot right? its been a long time since iv rejetted a carb ( on a 2-stroke) my plugs are tan but still have white on the insulator, the left plug has white and tan and the middle and right plug look pretty good so one cyl. is lean for some reason, any thoughts? heres a pic of it..

About time you posted a pic of it. Very nice. I agree with stock air box looking much better. Pods leave a huge gap under the tank and seat that doesn't look right in my opinion. Pods are sometimes a better option on some bikes depending on the airbox on a particular bike. But, I feel the Buffalo is not one of them. Especially if you are aiming to keep an original appearance. Plus, the carbs lose a lot of stability by not having the air box to mount to. It could have been that your old boots were leaking as a result of your carbs bouncing around from that lack of stability. If one spark plug is showing a different reading. It's obvious that cylinder carb is lean or rich compared to the others. Could be the boot, float level, different size jet compared to other two, etc. Now that you have the stock air box and filter on I would not change the jetting. Unless you would continue to show slight lean conditions. Then I would bump up only the main jet sizes one or two sizes. I would leave the pilots alone, unless you are experiencing idol issues that you can not solve or flat spots at low revs. Do you live at a high altitude ? I have a radiator crash bar that is in good shape that would look nice on yours I am thinking about selling.

Thanks for the info, ya i live at around 4,000.00 feet so shouldnt the bike be rich? at higher alttitude? That pic wasnt that good i have a better one but not of the airbox mounted, I put about 20 miles on the bike with the stock air box and the plugs still look kinda lean, just dont want to hole a piston, I have jetted alot of 4-stroke bikes and i know what the plugs should look like, and this being a 2-stroke I would like the plugs a little richer, the plugs would look perfect for a 4 stroke right now. The p.o. had the wrong crash bar on the bike, he had the early model, so it actually messed up the radiator cover, I had to redo the entire cover, I had to fix cracks all over it, it took alot of plastic epoxy and sanding and bondo, primer paint, took forever, anyway i traded a guy the old crash bar for a new one but he hasnt sent the crash bar yet (its been months) Ill give him a call, if he doesnt how much would you want for your crash bar? These might be better pics not sure?

also the bike feels great at low speed and idle, so i guess ill ride it for a while then check plugs again, if they are still lean then Ill go to the next size main jet, although most of the riding I do is at 1/4 throttle (around town) and maybe 1/2 throttle thats why i was thinking of the pilot? or turn the screws out another turn ,,, Ill see what happens... :?

She's a beaut. Try installing new or cleaned plugs, followed by riding the bike consistently at highway speeds. Read the plugs immediately after doing so. It's possible that you're putting around too much. I don't suggest wrenching the hell out of it. But, too much putting around isn't good for a bike either. Especially a two stroke of our kind. Give it some gas man. :mrgreen: I will take $65 dollars for the crash bar with shipping included. It's in good condition, not bent, etc. It's not perfect but well worth that price. As they are also very hard to get a hold of. If you are honestly interested give me up to several days as my work is very unpredictable. I'll send you a few pics. Everything you see on it when mounted looks very nice with no rust. There is minimal rust on the two lower mounts only and a very small indentation on the inner part of one down tube from a clamp that I removed due to someone installing highway pegs. That indentation can not be seen when mounted. It would look great if someone rechromed it. Or good as is. I am going to put it on Ebay someday soon. But, I'll give you the first opportunity. Under your circumstances I'd try bumping up the main pilots only one or two sizes. Try the next size up first. It doesn't sound that far off on that one cylinder and nothing to worry about putting a hole in the piston. But, bumping it up one main should help and surely will not hurt.
