RPM gauge not reading correctly By robert1c (Read 2,894 times)

Hi guys, I have an issue with the RPM gauge on my Linhai 250. The RPM gauge doesn't read correctly. It is very slow to go up and only goes to around 3k and I can hear that I should be higher when I floor it.

Where does the RPM gauge connect to so that I can make sure that's connected correctly?

Thank you all.

Runs off of the CDI and moisture can make it be very unresponsive also.

Also surely this is a misprint?

Sliders-Now running. Blend of 4.5 & 10.5s

Did you mean 14.5 & 10.5's? With your mentioned combination the RPM's would go through the roof!

Hi is the CDI the same thing as the rectifier? I have a spare one of those. (6 wires 3 yellow in one plug and blk,red,grn in the other). No its not a miss print I had 4.5 (4 of them) in there but they kept coming unseated so now I have the 10.5s and 14.0s in there.

No CDI is for the firing system and supplies volage to the coil. The Rectifier (regulator/rectifier) has the 6 wires you mentioned and if for charging the battery.

Can you tell me where you found 20 X 12 X 4.5 sliders? 7gram is the lightest I've ever seen. Your mix adds up to a balance of 12.250 each, why not just buy 12 gram ones instead? I run the 12g ones on my linhais because I run in the hills.

Sure thing. I got them here.

They have smaller ones the only issue was I need 8 and they sale them in sets of 6. So right now I have 6 10.5s and two of the black heavy rollers in there. I did like the take off I had I just don't like having to go back in there and re adjust them. I like to tinker but not that much

So I read another post while trying to figure out the light fluctuating issue and found a post about a relay from RadioShack that I could get that will correct the issue but my headlights will be on before the bike is on is this correct?

Thank you Richardthescoter3, that helps for what I am looking for. I think this piece may have cost me my first set of H4s that I installed.

Please tell me that you don't have 16 x 13 weight sizes in your scooter variator?

The linhai variator uses 8 rollers or sliders sized 20 X 12 and point blank they don't make 4.5g sliders at a size of 20 X 12 and if you had the 16 X 13 in there that's why you had to adjust them all the time, they were getting out of place because they were way too small!

The smallest 20 X 12 is 7g that I know of;

Even now your odd ratio isn't standard on 20 x 12 sliders becasue I haven't found any 10.5's out there.

They do make sets of 8 for the linhai and sometimes thjey are hard to find but they are out there;

If you are running anything except 20 x 12 x desired weight the variator will be a piece of junk in no time.

Robert we have a how to on replacing the blocking diode on the 250A and B but it again has nothing to do with your lights dimming, it is in the charging circuit. If you've got the VOG from the diagram it doesn't even have the blocking diode?

Do you have a on/off headlight switch and a dimmer switch? if so then you have no diode.

Can you post a picture or link of your scooter?

Again Robert if you are refering to the CDI that Richard posted a picture of it has absolutely nothing to do with the lights. Nothing to do with the charging system, it's only function is to step up the voltage for the coil so the spark plug will fire.

Here is the regulator with the blocking diode on a YY250T and this is the same set up for it's sister scooter with the linhai.




The CDI is the black box right under the diode.

Hi JR, thank you very much for being patient and trying to help me out here.

I will certainly post a pic of my 250B hopefully later tonight.
I still have packets the sliders came in so I'll check the sizes. But the 10.5s fit fine. The 4.5s did not and they are out of the variator.

Just to recap I'm trying to resolve the lights fluctuating it does it idle when it's sitting in the garage.

[robert1c]

Sorry I missed including the second issue I would like to fix which is the RPM gauge not going beyond 3500.

[robert1c]

Hi RJ I keep tring to post a video of my scoot but it keeps logging me out. its only 1.5 minutes and an mp4.

[JR]

I'm not a video man Robert most people go sign up for a free youtube account. Robert I'm very confused? You say you have a VOG and now a 250B? Both have lihais but are different scooters so here is a video of each;



Know widehide and the silver scooter is the 250B.

[prodigit]

Thanks for the vids man!
So how's the BMS TBX 260 / VOG 260 do against the roketta 250B both speed, torque, and mpg wise?

[robert1c]

Ok sorry. I am new to scooters. I got mine on the July 4th and have done nothing but work and ride on it. Mine is the Roketa MC-54-250B.
