APC (PEP BOYS) Mini Harley questions.

Hi,

I have an APC mini Harley and need to know a few things that I couldn't find in a search.

How much and what type of oil is used in the transmission?

What is the best way to convert from the dual rear wheel to a single, larger diameter rear wheel?

Are there any wiring diagrams available?

Been searching the internet for hours looking for this info. I appreciate any help you can provide on any of the questions.

Thanks!!

I think SpyGuy would know about that bike.

Re: APC (PEP BOYS) Mini Harley questions.

Thats the same model as the bike I have EPR......I also have a dual rear tire model too..

The transmission gets 100cc's of 30 wt oil...

The rear tire can be converted to single rear wheel you just need a rear wheel assembly..

Re: APC (PEP BOYS) Mini Harley questions.

Hey, thanks so much for the info. The twin engine "Harley" is a hoot!

But where can I buy a single rear wheel assembly??

Thanks again,

Re: APC (PEP BOYS) Mini Harley questions.

Go to davesmotors and get a 49cc Cylinder, piston, rings and all for about $12, that will give you more power now. ww295, ww268, ww271, ww110 15mm V-stack, and dr123, rocket key, timing advance key.

Re: APC (PEP BOYS) Mini Harley questions.

Thanks for the info guys. I did order a 49cc "kit" from Daves. Thanks for the "heads up" on that. Crazy low prices!

Is that wheel from "Scooter Parts for Less" a bolt on deal? Which tire and tube do you order? What do you recommend for a sprocket to restore the gear ratio with the larger tire?

Sorry for so many questions....

We MUST be talking about different transmissions though... I drained mine for 15 minutes and then could only get 45cc of oil into it after an hour of trying, waiting for the oil to go down, turning the trans over, trying again, etc.... It certainly doesn't look big enough to hold 100cc of oil in any case.

Thanks again,

Re: APC (PEP BOYS) Mini Harley questions.

Dude, we all have Questions, all the time. daves is clearance there not restocking anything, thats why I told you Now. I have been stocking up on Cag & Zenoah parts for a year now. Just built a new 16mm Walbro Butterfly pumper carb & V-stack, for my Hopped up 49cc Zenoah engine I am building juat finished this Cag engine today, very high compression.
I don't know about the oil part, you just need enough to slosh on the chain and keep it lubed & cool.

Wow, looks great!

Cam2, did you notice my questions about the single rear wheel assembly?

Thanks,

Re: APC (PEP BOYS) Mini Harley questions.

Sometimes the single rear wheel is harder to find than the dual rear wheel setup....I have a couple rear wheels around here somewhere..One is set aside for the Red APC with dual rear wheels I have............

Re: APC (PEP BOYS) Mini Harley questions.

Cam2, Hope your filling Better. I want to drop the new engine in the Lucky 7, if I do that it won't start, and then there is the exhaust fitting problem. I have 6 different styles and had to cut one in half to get it in a bare frame w/ the rear clip off.

Re: APC (PEP BOYS) Mini Harley questions.

Good News, since I could not put the engine on the stand, cause of rain, I took my #5 engine apart, put the FC Crank in it, then it goes to Sam for the 3rd Stage Kit, that will give me 2 Drag engines. I will have something to mount in the 2 engine frame as I build it. That 49cc stocker has a 12mm bearing rod and them middle fingers in the side ports, and the clutch had no key or keyway, but it was glued to the shaft, so I took the cases apart on the flyw side and held the cases and one shot on a socket on the end of the crank and the clutch poped off. Will still use that crank in another stock engine later.

Im shipping my engine out to sam in about 5 days.. need like $20 more fore the 3rd stage and swirl carb.. he said he can also throw in that fcc i bought a few weeks ago. Cant wait! My cag is going to be a beast when i put on the 3rd stage and fatty pipe if pbp gets then in stock. Hopefully he can fix this bogging problem in high rpms if i cant figure it out. im sure its the float tho

Pull the sparkplug to see the burn....

Does the bogging require you to back off the throttle a bit to keep it running or it will eventually stall?

If so youre most likely a tad light on jetting and the plug will be a white,tan or gray color...

If the plug is black your air filter may have too much restriction or your reeds have too much flutter and no real seal...

Re: APC (PEP BOYS) Mini Harley questions.

Methotic way to go sending my next one at the end of this month. Better get a good padded glove for starting it, I use two gloves, and start at TDC or just past. Both my Swirl bored carbs work great.
You high end problem could be like Cam2 said, alot of little things can make your engine not peak out.

Re: APC (PEP BOYS) Mini Harley questions.

I am having trouble going through (ruining) rear wheel bearings on my dual rear wheel APC mini Harley.

I am not sure how the spacers should be, as I bought it as a basket case.

On the rear axle, I am assuming the spacers should stack up during assembly of the axle and wheel assembly so that the axle nut clamping forces are not putting pressure on the bearings, only on the inner races of the bearings and the spacers. Is this correct? If I shim the center spacer so that the clamping force of the axle nuts is only clamping on the spacers and inner races, that lets the two wheels have a little slop in their notched sleeve connector. Is this normal?

Help!

Thanks,
AV8TOR

In the center of each wheel between the bearings there should be a bearing spacer tube thats 4-6" long between each bearing in both rim hubs...........Then you should have 4 other spacers of different sizes,,an axle and two tensioners to attach it.........

The largest of the remaining 4 spacers goes between the dual wheels,,,The second largest on the sprocket side,,,3rd and 4th are on the brake band side............The slop between the lovejoy tabs is ok...I use rubberized tool grip dip on the tips to make them not slap

The axle adjusters should be insibe the swinmgarms with large washers and nuts on the outside.................Good Luck

Re: APC (PEP BOYS) Mini Harley questions.

Ok, thanks. That's the way I have it set up. I guess I lost the second axle bearing just because it was a bad one...
With the slop in the "lovejoy" tabs of the inner wheel spacer/connector, the bike feels a little squirrely. When the power is absorbed by one wheel, and then the other when you lean the bike a bit, the slop in the dual wheel assembly causes a little wobble in the handling. It seems more noticeable on dirt roads than on smooth pavement. Is this just the nature of the dual rear wheel bikes?
Thanks again,
AV8TOR

Basically yes.................Bad bearings will enhance some wobble but there will still be a lil when the bearings are good...............Thats why I dip the lovejoy tabs in tool grip plastic dip...........Make sure the swingarm bolt is snug too.................

On one of my bikes when the bearing went bad the axle tube spun in there so badly it got worn down a millimeter...That millimeter loss to the tube was enough to cause rear wheel tightening problems as I think back to my dual rear wheel red one which I hardly ride since I have the twin engine one now.................
