1989 Yamaha Riva Razz 50cc Scooter (SH50) - Will It Run? 

I just got a 1988 Yamaha razz but its red

Fr sounds like a turbo, or hover craft 😂

Benjamin Goodstone ya they are slow haha but I heard you can remove a little spacer in where the belt is and it will pickup 5ish mph? I might try it! But ya they are pretty bulletproof little scooters!

That’s how my brothers raz broke😂

David yep pretty fun little scooters!

blackcat_NZ gaming that’s awesome!! Ya they are fun, affordable, little scooters!

@@Mechanic_kid the big brother of the razz is the jog it tops out at 42 mph where the razz only does 30 mph

@@W202J i run 87 no ethanol in my 99 razz and it goes about 32 normaly but 38ish downhill

Thanks man👍🏼 I’ve got a few videos on it, go checkout my channel! Planning on doing a lot of work to it this summer🙏🏼

Join this Facebook group. They are super helpful and someone will have a extra carb or know one that fits👍🏼 facebook.com/groups/YamahaScootersOnly/?ref=share

Common problem. Remove the line from the oil tank to the oil pump. Cap off oil pump. Drain the gas and run premix gas. 40:1 ratio. (3.2oz of two stroke oil to 1 gallon of gas). I run premix on almost all of my scooters, then i know the bike is always getting the correct ratio. Best of luck👍🏼

Chances are is just the bulb is burned out. Should just be a couple philips screws to pop the covers off then push in and twist the bulbs out👍🏼

If it’s chain drive there’s probably not way to make it go faster unfortunately

@@Mechanic_kid unfortunately I think you are right. I couldn’t find a washer restrictor? It feels like it wants to go faster. Any thoughts. 30-35 would be ideal. I ve replaced spark plug and adjusted carb with no luck.

@@carysewall932 i think the washer restrictor is only on the varitated models (belt). Your only option is probably to get a larger carburetor and a better exhaust pipe. Might be cheaper to just find a fast scooter. Honda aero 80 I really like! Goes 40 easy. You could give scooter swap shop a call and ask if they have any ideas. They know a lot more about scooters than I do👍🏼

Not getting fuel! You need to clean the carburetor.. very easy! Take it apart, take out all the jets and spray carb clean through them. Put it back together and should run perfect. Now a days when you let a scooter sit for more than a couple months, the fuel cloggs up the carburetor and it won’t run right. Hope this helps you out👍🏼

@@Mechanic_kid I will do that first thing in the morning tomorrow thanks man!!!!!

@@martinnovelo4351 no problem. Let me know how it goes!

@@Mechanic_kid will definitely do

@@Mechanic_kid I cleaned it and it's running now !!! Idling a little to high but at an least it's running , I cleaned the carb like said it and it worked!! THANK YOU!!!!!

I believe it is true! I think it makes the variator be able to move a little more, resulting in the belt going higher up which would give you more top speed. I am not 100% tho. If I still had the scooter I would do a video and test it out for you. Sorry hope this helps👍🏼

@@Mechanic_kid thanks for the reply!! I thought it was chain driven so i didn't even think it had a set up like that where there is a variator

@@Thats_Bogus oh you might be correct! I guess I just assumed it’s belt driven like the spree and elite. If it’s chain driven I don’t think removing a washer would do anything.

Razz doesn't have a variator you can adjust the clutch on them it sucks

I block off the oil injector and run 40:1 on all my scooters.

@@Mechanic_kid thx...just picked up a razz...oil tank is gone...so yeah ....i gotta premix

i run 40:1 radio in all my scooters. 1 gal of gas and mix in 3.2 oz of oil👍🏼

@@Mechanic_kid I know how to mix th feul and 2 x stroke out I am talking about the sump where you put permanent oil in It got a plug in the back where you put this oil in Appreciate your response Thank you very much

@@pietsanvenero9756 Oh gotcha! Not exactly sure the exact size of that tank. I usually just slowly fill it up to the top. Best of luck👍🏼

It’s like 25mph I think. But with some after market parts and tuning could get probably 30-35out of it

@@Mechanic_kid These are a ton of fun! I recently purchased a '92 from the original owner who used it almost exclusively in campgrounds. Less than 800 miles on it! I guarantee he didn't modify it and I'm getting GPS verified 35 on a downhill grade, I weigh about 150. I'll have to get some videos of it posted. I've owned a few Expresses in the past that admittedly weren't in great shape, but this accelerates so much harder than they did.

@@frozenfist3360 hey 35mph is pretty good!! They are pretty fun little scooters! Thanks for sharing👍🏼
