Good to hear it is running well.It's good to have the tuning ability sotake out the red stuff. LA has fast days and slow days.Dry days when the santa ana winds blow you will find outis a fast day and may want to tune to that. Foggy daysor damp days are slow days and you could tune betterfor it.

I have had a lot of A55 mopeders come to my shop to dial in and tune theircarbs for them that had the 77 carb kit put in. The answer is to take out the speed kit and change everything back to stock. For 50cc with a pipe and unipod you should be running 60 to 61 main jet with everything else stock. 50cc with a pipe and stock airbox is the best running using 58 to 59 main jet which is about the f

3. Re: Know anything about Tomos arrow r?

Marvin Yee — 8 years ago
Forum: General Discussion
There is something about the arrows performance wise. They are fast for some reason. I don't know if it is because of the smaller wheels. They just tend to pull quick. I have a 2008 arrow r with the 17t and it will do 51 mph. It is 50cc but it has raised and ported exhaust on a shortened bullet exhaust pipe with the stock 14 phva. The same motor on my streetmate would only get up to 48m

Hey!!! Who is this guy posting as me? I have not been on this form for a long time. If you don't like Whizzers then say so, but don't go impersonating someone that like and has pretty fast Whizzers. I have 3 that get out to 55 and DON'T BLOW OUT OIL AND GO ALL DAY LONG. And the guy in Fullerton who makes the overhead cam engines, his name is Fred Konke who is one of the guys

Been there and done that. Quintin sells a lot of parts for the bikes. It has to have a better way to start the bike as the existing clutch is inadequate and is prone to failure. Some guy in Fullerton Ca. makes overhead cam engines for about $8,000 and they scream to 65 to 70 mph. The one and greatest failure of Whizzer engines is the oiling of the motor which is like a Briggs and Stratton with

6. Re: A55 performance build

Marvin Yee — 9 years ago
Forum: Performance
Robert, try raising the exhaust port 1.2 mm. Then widen the port and square it out a bit. Cut the piston skirt on the intake side 3.5 mm for more intake duration. With this set up I run 54 jet and the stock air filter with Technigas next pipe. This gets close to max rpm limit.

7. Re: A55 Exhaust + Upjetting Question

Marvin Yee — 9 years ago
Forum: Performance
So sorry. I will answer your question. If you bought the pipe for an a55 it should work. The big question is the word should. All a55s have the same angle exhaust port and therefore should fit. Sometimes they need to be fudged to fit. About 95% will fit. Now that you have the pipe you can tell us if it is a good snug fit. I had 2 pipes that fit my Revival and 1 that didn't.However way

9. Re: tomos streetmate wiring harnes meltdown

Marvin Yee — 9 years ago
Forum: Repair
The harness can be picked up at any Tomos dealer. I highly suggest you do that as I have seen other bikes spark up from filling up fuel. There will be too many bare and burned wires. Never just push the nozzle of the gas pump onto the gas filler on a Revival, Streetmate, Streetmate R, or Arrow R. They have batteries and can short out if not fueling up carefully.

10. Re: Jetting... It's not as simple as a plug chop.

Forum: Performance
You are running rich. Hope you don't have the jet kit you told others to use. Try the stock idle jet and infuser and between 68 and 72 main jet. Good luck and hope you don't seize. 14 mm carb is too low volume induction for a kit. 16 mm and larger work better. I have seen more 14 mm carbs with kits seize than anything else.

I don't know how and why you would promote or advertise that kit. It absolutely will not work. If You want problems and never get it dialed in, that is the kit for you. Run a 58 jet and the stock air box. Stock air box has the best flow with the stock carb. If you have to have a free flow air filter use a 60 jet. Use the stock infuser and idle jet. When your motor is warmed up adjust t

Use a PVC rod holder and fasten it to the side of your bike and use a bungie cord to secure the pole. I'm in north Long Beach and have gone down to San Pedro and PV with a 7 1/2 and an 8 foot pole. Good bay bass fishing in Back bay.

15. Re: Attn Tomos Arrow Owners

Marvin Yee — 10 years ago
Forum: Performance
It has been 4 years since Tomos has discontinued the Arrow line and not so many sold in the US. I think it could possibly be the best base to make a race bike. How badly do you want a 18t or 17t rear sprocket? The machining to fabricate the sprocket is quite expensive especially if you only need 1. It has to be fabricated using your old sprocket hub and an 18t or 17t sprocket and welded. I�

17. Re: Moped Factory - Tomos A35 16mm SHA Intake Review

Marvin Yee — 10 years ago
Forum: Performance
The 16 mm is very close to the optimum not maximum and therefore should be very snappy on your throttle. You should be able to reach 52 to 55 mph by shortening that pipe 3 3/4 to 4 inches. I think that was the year that some of the cdi units didn't have the rev limiter. Hope you got the better one. None the less I think you have a pretty sweet set up.

Mike, If you can find an estoril for the a35 it has a larger header pipe.Since you have the mig shorten the pipe 4 inches by cutting the weld from theexpansion chamber and pull it out. Cut the pipe 4 inches before the weld andweld the expansion chamber back on with no pipe leading into the expansionchamber. Do this and keep in mind how you need to fit the pipe to be boltedon securely. This mod

Sorry I don't work for a Tomos dealer anymore. It works because of the high pressure air collected in the frame where the air box gets its air from.

Hi guys. In my 5 years of working on Tomos, I think the engineers did a great job on the stock air box/filter. Don't modify the air box in any way. It is the fastest filter system you will experience as long as you are using the stock 14 PHVA. Test it against any free flow air filter and you will find out the stock air box/filter is superior and 2 mph faster. When working for Tomos I fou

If you need a spare key and the dealer won't have blanks, you can go to anyplace that makes keys and have them shorten a Dodge/Plymouth key to the size of your Tomos key and have them copy it. The Dodge key is the same pattern, just longer. (When I worked for Tomos, there was no such thing as getting new keys outside of the 2 that come in the crate of a new bike.) The only way to get a key

There is no way the flywheel can slip with the pin in. If it slipped the flywheel or the end of the crank broke which will give you all kinds of problems and may even scrub the magnets in the flywheel. It is not your timing. You have explained the symptoms of having air leaks. I would check the base gasket or the leak may be from the case half. A leak in the case gasket may have been the caus

Hey Adam, did you find your answer? Lots of conflicting answers. It is better to balance the clutches pieces than to lighten them. Green spring shortened 3 coils with 1 1/2 oz more trans fluid than normal should do it for your specific motor. The power in your motor should bring you out to 29 to 30 when your shift.

Yes it will work and bolt up. The problem is the intake of the a35 will not fit. If you have the intake for the a55 it will be superior over a35 ( manifold and carb).

marvyhi — 11 years ago
Forum: Performance
Don't mess with the transfers at all. The angles in the transfers should not be disturbed and they already flow much more than you can use. Raise the exhaust port window about 1 mm and square it out than funnel port the exit to fit your pipe. 25mm exhaust is about the largest you will fit to the existing studs in the exhaust port of the cylinder. This should get you blasting close to 50 m

The idea is to manage the heat. To retain the highest heat will make the most power. The idea of the coating is to keep the heat from absorbing into the piston crown and head to retain the highest heat in the combustion. To thermal wrap the exhaust will make a little more power as well. The exhaust coming out the back will be much hotter. The engine will run cooler and you will have a little
