heating up going up incline  By  wycpihdyn (Read 811 times)

long story. the story that goes along with this. ...
yea, i dont even want to get close to there. so i been going, 1 number at a time. but what i did do, was up that main jet another size. and it sounded, better. .. like get it? sounds more like. a bike it's supposed to sound, like. sounds right.

ok a few things, found out that since i was lean on the main jet. which i was thats why the too hot, but give me some tips to get this running. that main jet, is more like it. still, dont know if going on down the road, that it will over heat maybe, or not. but its 1 size bigger yet again. so maybe this one will do it.

but ok, so i went out today, and done some more tuning. and found, out my needle, i was getting, no throttle response from 1/4 pretty much until it was full throttled. wot. it would just go like, burrrrrrrrrrrrrrrrrrrrrrrrrrrrroooooorrrr. another thing, my belts stock and im waiting on a shipment to get to me from china so i can change belts. and i have a little bit of bad running, anyway around 30mph becuase of the belt, and maybe my roller weights. i might have to order a set. but not until i .. switch over my cvt. to use the new belt. waiting on a variator.

so its kind of tricky figuring out. maybe im just now, wrong rollers? but. i been going by, letting it coast down a hill, or start to run good, rollers switch gears, i think a little quicker than sliders, ive got 5gram sliders, 7 gram rollers mixed right now. i had switched from pretty much all the time using 5.5 gram sliders over. since i started jetting better...

maybe a switch but since sliders, take longer to shift. ive got some 5.5grams. reason i started really to switch is i mixed up the 5.5 grams and 5 grams cause my scales where left somewhere else. and i didnt know. and thought wow i need to heavy these things up. thought the 7 gram rollers where doing pretty good too. i liekd the top speed they gave me. and i thoght tune the carb to them. i kept trying.
but switching to sliders, might, be 1 step too light. i can try.

so, alright that. and i was messing with the needle settings. ok its a dellorto 21mm carb. and i got a 72cc bbk. pipe for the motor and everything. no airleaks, been leak down tested. so i was running, really rich 1/4 and 3/4. well, when the main jet was finally set in. i had a couple pilot jet problems. like it cant make up its mind. or maybe, its the bbk and the whole deal with that. so, seemed my pilot was finally tuned in. and the main jet was tuned in. but still, wouldnt run.

well, running down the road, i can loOOK and look at the cvt, but thats telling me nothing. much really. ? what temps? am i supposed to see as i first start it and it burrrrrrrrrroohh down th eroad. i reached down and grabbed the manifold, and it was cold, and wet. so, iwwas rich. knew that. but theres 2 parts of the needle, the 1/4 and the 3/4. didnt konw where i was coming from, but now with the PJ and MJ tuned. i just held it at 1/4 and put my hand over the air filter, or would grab and pull up on the choke as i was going down the road. or touch the manifold. you gotta hold that posiition like 10 seconds or more at least, its like tuning the PJ and mixture screw. turn the mixture screwk then you gotta let it settle for 10 seconds to get a right reading. so it was wet. tried going both ways, see where i was at. went extreme one way. pretty sure it was wet at that point. i tried a couple clicks the other way. still, same acting, just a borrrrrrrrrroh gonig down the road. so, i was like, main jet was chnaged. maybe im on the wrong taper of needles.

see the dellorto needle jetting chart, and youll see 1/4 throttle L_angles, change on the tapers, the 1.0mm tapers and .6mm tapers have the same types of L_angle needles. then your 1.4mm and 1.8mm have the same types of L_angles too. maybe some oddball in there, but i can't remember.

so, everyone i hear, goes, use the w7. tried it. not the best at taking off. i played with my pilot jet mixture screw setting. made, i think the jump, a little better. and the cvt isnt trying to switch gears, anyway at least, until aro9und 30-35 depends on how them heavy rollers want to act. belts also at service limit.
soo. well, i guess tomorrow, when i can, maybe ill just drop the needle once more. no weird stuff is happenning. i went, to the w7 needle. i think the 3rd click down. i just thought sometimes stuff was cutting out as i ripped it back. maybe it was just, boom too much gas. but i dont know. guess so. guess ill find out. like as i ripped it back, all of a sudden, it would, boom just die the engine would have no more sputtering, but then itd kick back on.

weird stuff. if i knew like any of the stuff, like, rich cuts out just as lean. but i dont know. and temps or .. um how much the needle should be close to the extremes of tuning with the jettings the way it was.. whatever. but since i have been tuning right now, its not been long so, these problems are just poppoing up. way over rich on my needle, but it was going better the more and more i set the taper more. never had much response from my bike before. and then my main jets off. just 1 step and this.

maybe i need to tune the atomizers. ehhh

8 ngk. still havent retuned the carb or done another long speed run. got dark befoer i finally got it running about half alright.

take off sucks for me. but if i dont go over 1/4 throtle right now, i have power. and it goes. and i can, get to where im going.

its best to go rich and tune from there. get yoru main jet, i guess plug chopped. also got to have a tuned cvt. heavier weights dont screw nothing over. lighter ones will make it not run right. i know that. heavier, youll just have a hard time getting to where your going.
and a cht gauge probably saved my bike, from me blowing it up, 30 or 40 times.

premix, plug in pump an oil pump plug. trailtech tto gauge.

i couldnt even tell before the cvt wasnt running right when i wasnt tuning the carburetor right. i couldnt even tell, that it wasnt tuned right.
