running problems

[nitrogator]

well i have an aftershock and it runs great with 1/4 throttle then ok with 1/2 throttle and when i give full throttle it dies any suggestions

 

[BOUTCH]

Just an idea...

I'm not sure but i think your running too rich...did you set your HSN(high speed needle) and your LSN(low speed needle)? Try leanning your needles a bit, maybe a 1/8 of a turn at a time. Correct me if I'm wrong anybody, thanks!! Hope that helps!!

 

[nitrogator]

i put a new exhaust on it and now maybe i need to go back to factory settings and start over i had it running great till i put the new exhaust on it the first tank ran great then the second tank is when this started
will setting it back to factory presets work with the new tuned exhaust it is a losi tunned pipe any help with this problem

 

[nitrogator]

i tried adjusting last night and it is still bogging down at full throttle any help

 

[BOUTCH]

DAMMIT!!! Did you set both low and high speed needles? And how much did you lean them? how much did you turn them?uke:

 

[nitrogator]

yes i went back to factory spec and started over and still cutting off with full throttle all adjustments were done in 1 hr incr.

 

[BOUTCH]

WTF!!! I dont get it!!! Gonna have to let the EXPERTS anwser that one man sorry...gonna check if it can be caused by som' else and come back to ya. Wish i could of been able to help but guess not...

aftershocks are SO ANNOYING to tune. i am trying to re-tune mine from factory settings and its not going well. my experience from an aftershock tells me that your high speed needle needs tweaking a little leaner.

Aftershocks seem to want to do there own thing! you tweak something then tweak something else and it does exactly the opposite of what u want it to do!!!!

Good luck man!

 

[nitrogator]

man I've been tweeking and tweeking and tweeking i am thinking it may be something else but i just dont know what

 

[wilxayboi]

well if u think about it then it can't be anything else because the LSN is for 'low speeds', and the idle screw if for... well, idle speeds and the problem u have if I'm correct is that u can't max your throttle, which obviously is 'high speeds' (HSN) so it must be just a case of adjustment in the high speed needle. i can speak from experience on afershocks and they really are hard to get exactly right so if this really doesn't answer your problem then i can offer no more help.

I am really looking forward to hearing how this is fixed so any more help from the rest of you guys would be appreciated by not just nitrogater but me as well.

Get it to running temp, Lean HSN an "hour" run for a minute check temp / performance if still bogging, lean again run again check temp / performance again - if it starts to get too hot (if you haven't got a temp gun spit / water should sizzle off slowly over a few seconds not vaporise) before you get the pace your expecting then it's poss another issue thats above my knowledge (I'm still noob the onto it people seem to be absent but I know my motor was doing the same and the 'sweet spot' was quite hard to find (went past it and although FAST came in hot so I took it back down a half hour and it's about perfect) and of course once I found it I crashed my car hahaha

I Have Started Back At Factory Specs And Adjusting In 1 Hour Incr. And Still Cutting Of At Full Throttle i have a temp gun and the temps are around 200 ...i Thank You For Your Help Wilxayboi AND 2000DELUX

 

[2000delux]

Can go above 200 but not much huh, if it was getting hotter I'd say maybe bad filter / air leak or something causing false lean condition but you'd expect that throughout the rev range not just WOT - I'm out of idea's we need a Rolex or someone in here.

My ears were burning....
If it's getting off the line okay, and running good at 1/4 and 1/2 throttle, DON'T mess with the LSN.
If it's dying at WOT, it's a HSN issue. Get it running, and get it up to temp. Then put the nose against a step or cinder block so it can't move forward.
Pull the trigger, and as soon as it starts to bog, let off. If it kind of blubbers, lean the HSN. If it just cuts out, richen it.
Don't hold the trigger long, just enough to make it push at a quick WOT. You want it to work hard, but you don't want to overheat your clutch or slipper.
Always give it about 30 seconds or so to 'settle' in to the new settings by idling while you give it short little blips.
If you get the blubbering at WOT and start to lean it, and it doesn't improve, go in the other direction. If you still can't get a satisfactory result, it's more than likely that there's an air leak somewhere in the loop.
Adding the new pipe could also be part of the problem. If you have the option to shorten or lengthen the pipe connection, that affects either the low end or the WOT.
If you can't get it tuned by the above method, put your stock pipe back on just to see how it will behave. If you still have the same problem, or it cures the problem, let us know.

well guys i have got the aftershock running like a scalded dog it took a while i brought it to work and finally i got it...man i wish the wheelie bar i ordered would get here now i can't keep the front tires on the ground...it was the high speed adjustment just wasn't doing the adjustments right i guess....i was not waiting 30 seconds between adjustments .....and that losi tuned pipe made a huge difference thanks again everyone for all the help
