Throttle Blurts...Help

[wanttodunealways]

Hey everyone. My shee keeps acting up and I dont know whats up? Any Ideas? This is what it does... Starts just fine but once warmed up the throttle revs up and down uncontrolably (especially when I am on the throttle). Feels like throttle is sticking but does not stay stuck open like carb slides are dirty. Can float settings cause this? Thanks for your help.

Tors maybe?

 

unplug the the plugs on the ghetto things on the top of your carbs 2 of them, if you have stock carbs

and on your parking brake follow a wire back and unplug it as well

try that and see what happens

oh oh and right above you left cylinder there is a black box attached to your frame, unplug that and garbage the black box

yah could be a tors prob do you have the removal kit also it could be runnin too lean

[wanttodunealways]

I am running the stock carb setup with the tors. What will happen when I unplug all the tors electrical? Where in the tors setup could the problem be? Lean could be a posibility because I have not re-jetted for colder weather. I am currently running what Toomey suggests, 280 main, w/T5's, K&N in the airbox with lid, no snorkel and air box vents. Also, a few weeks ago I noticed my coolant boiling out when I went on a night ride at glamis. The shee got pretty hot and I stopped half way back to camp to let it cool down. Night temp was around 40deg compared to almost 80deg in the day.

it almost sounds to me like an air leak?

[FasterThanU90]

yah sounds like something is making it run really lean

Air leak seems feasible...I'll try and check for air leaks also. I wanted to remove the stock airbox and put the toomey 2:1 filter to try and eliminate possible air leak spots. Is anyone running this setup?

I am running the Toomey 2:1 and as with any open element filter, it is a great way to make a bit more power. However, recognize that the filter does not create a source for a leaning air leak. It could allow unfiltered air to enter the engine, but a leaning air leak occurs after the carbs. When air enters the carb, a specific amount of fuel is added to that air to provide the correct air/fuel ratio. An air leak after the carbs adds more air, causing a lean air/fuel mix.

You are absolutley right...That did not even cross my mind, Thanks. Do you know about how much I should increase the main after I add the Toomey 2:1 filter? Currently running 280.

I would jump to around a 320 or so for starters. I have a friend with the same mods (jetting affecting mods I should say) that I jetted, and ended up at 330. I run 340's. I would say probably a minimum of 3 jet sizes, but more likely 4 or 5 sizes. What elevation/temps are you running?

[wanttodunealways]

I ride Glamis, sea level and 60-70deg days but night can drop to low 40's.

By the way, last night I re-tightened up my carb clamps and fired it up...runs great. It was for sure leaking air between carb and intake boots. Thanks for everyones help
