wheres a jetting chart

[registered user]

got the clymers and yamaha manual but dont see any chart in either book. is there a chart around here ? main is 200. not sure what everything else is but probly stock. seems to go pretty good in higher rpm but low rpm its real boggy. 6,500' 70f. also what plug is it supposed to have ? yamaha manual says b8es. clymers says br8es. what im wondering if its supposed to be resistor or not

i looked there but seen no chart. some dude posted a link to a bunch of stuff but for some reason i cant download it. you figure there would be a chart in one of the manuals but i dont see one. if it has 200 main and the rest is most likely stock what should i be using for 6,500' ? looked at the plugs and the mains aint bad plus it runs pretty good on the topend so i know the mains are in the ballpark. problem is its real boggy at low rpm. if its idling and you try to rev it it boggs then eventually the rpm will go up. never messed with these mikunis either. got keihins on all my other junk

If it idles and starts easy, your pilot is good. Look at what size pilot you have and check what clip postion is on your needle.

Your up there. Well ive had PWks on mine. But when i would ride up in elevation fast you can feel the power loss . So your 6500 ft up, = less air

So if you have 200s in there for stock jet. Prob not right.

Is it cold there? Cold air you might be able to run a bigger jet hard to tell

think i found most of the problem. the air screws were only 1 turn out. turned another 1/2 and it sounded better. probly 2 or 2 1/2 is where i need to be. ill try it tomorow
