Brian, great video and love your channel. Cruising several vids now to solve a flame out and deceleration backfire issue on 2010 CRF450R. Thanks for all you do!
For Suzuki owners, this isn’t how you test the TPS. This just shows there is resistance, not that it’s the right resistance. Between the Black and Blue wires it should be 5 ohms. Between black and yellow, you fully open the throttle and it should be between 3.09 and 4.63 ohms...rotate the tps to get in that range then lock it down.
@Amopower In this situation I would check the wires to the computer for pinches to the frame etc where a rock or a riding boot may have created an intermittent unwanted contact to each other or wire to ground.
Checking things like that is where an old-fashioned analog meter comes in handy. You can see the smoothness of the change a lot more easily on an analog meter.
I was wondering if you knew how to determine where to set the sensor at so the dirtbike will start and run which I have a 04 Honda CRF250R that I am so tired of kicking!
Hey! 2020 now. But I have a 09 and I gotta give it some gas to start it and it takes awhile to start some times backfiring but it'll start up and won't idle. But the thing is once it's on, I gotta keep giving it throttle to stay on and it'll rev out and drive great.
Hi Brian - in order to get the TPS properly positioned on my 94Probe, you supposedly have to rotate it until you get continuity at closed throttle, then insert a 0.006" feeler gauge between the throttle and throttle stop, check again, and verify continuity still. Then, with a 0.020" feeler gauge, verify no continuity, I have done all of that, but I always get a fault that the TPS voltage is out of range. I am not sure how this can be?
Put the right year computer in it. The customer swapped out his 04 Zuki for an 07 Kawi without swapping the computer too. The throttle curve, timing, etc were all off.- customer failed to tell me this.
funny you upload this - i think mines dodgy atm - the idle valve i've cleaned - the throttle body is immaculate - no vacuum leaks (i think) - so will try this 2nite! thanks
So every 2 wire combination you should get movement? Out of the 3 top left and bottom stays at 3 ohms no movement however with your combination I get the same on my Honda CRF450R
@briansmobile1 mine seems to be ok, i disconnected the vehicle speed sensor which have problems on fords, the revs don't hang anymore - so i need a new VSS, but it still stalls, so a new idle control valve is needed too!
what if the tps has 4 connections...say like on a '94 dodge colt....on the actual tps above the connectors is painted/marked ( + 0 S - ) without the parenthesis of course...the "S" could be an "8" it's kinda hard to tell since they are somewhat faded

@Liamautomechanic YES! And I'm good for it! How've you been?

@TheMozza76 There are manufacturer specific tests for that.

If I get a new throttle position sensor do I need to set it or will it be good when I put it in
It's the carburetor! I can tell it's never had a mid body o ring kit installed the epoxy is still in the Allen heads.
@grishenko45 You're welcome- good luck. This one wound up being the wrong computer year supplied by the owner.
hi buddy how are you these times. any snow there yet.??

Will the bike run with it unhooked?
Will a bike run without the tps hooked up
So what ended up being the problem

My r1 has to be between 4k and 6k ohm that bike is diferent?
so just a quick question my bike wont start on kick but if run started it runs like a dream any tips on what i should check?
Valve adjustment, compression, and carb cleanliness.
@@briansmobile1 i have reshimed the valves to spec and cleaned the carb, the only thing i can not realy do is check my compression.
@@briansmobile1 so i found out my tps is just dead but can this be the problem of the bike when kick starting?
I thought you have to have the bike running under its own power or 5v on hondas
what if the tps has 4 connections...say like on a '94 dodge colt....on the actual tps above the connectors is painted/marked ( + 0 S - ) without the parenthesis of course...the "S" could be an "8" it's kinda hard to tell since they are somewhat faded
How can you tell if the TPS is out of position?
Very true
how did you fix this bike?
Hell ya- no worries
wires are colored blue for the +....green for the 0 ....yellow w/red strip for the S...and black for the -
Thanks for the info!
You bet!
thanks for tellin me man
I would never buy a used 4 stroke. To many things for people to screw up. With a 2 stroke its limited and easy to troubleshoot.
Couldn't see a thing
