77 Batavus restore -Newbie!

I have a 77 Batavus HS50 that I was given last month. Been working on it for a while, have Fred's Guide... and it really WANTS to start now. I've replaced the petcock, fuel line, spark plug AND boot, pedals, de-rusted, fixed the clutch lever (somebody tightened it so much it wouldnt release!), checked for shorts in the wiring, thumb-tested compression (no guage- but blew my thumb away nicely) and cleaned the points. I've also started painting it since the OG paint was shot. Last time it was running was 2001 according to sticker registration. I can get it almost running roll-starting it down a hill, and it softly runs for a few seconds then dies. This is a big improvement from doing nothing at all. The flywheel cover is gone and has rust but the coils look clean and the points are cleaned and seem fine. There IS a leak near the carburetor. I know from building motorized bicycles that new engines just take some time to "catch" and run... do I need to keep rolling down that hill till it goes or am I missing something? (which is my guess, since this is all still new to me) I dont have a lot of tools yet and I'm still in the "just started learning" phase. Need some help from the "been doing this for a while" folks like yourselves.

Thanks for the advice ahead of time.

Dave

is compression good? definitely flooding out from the carb leak. fix, get a few plugs n try to start with petcoxk off throttle wide open.

Alright. If it has the stock carburetor... I'd suggest that you buy a new Dellorto carb. A good step would be to clean the points. In the meantime you should take the carb off and clean it realllll good. I usually start with carb cleaner and then go wash it with hot water and Dawn. After that use an air compressor to blow out all of the passages.

Later on you should definitely replace the points and condenser.

I love the top tank style, I had an hs50 a few months back and I miss it. Definitely second cleaning the crap out of the carb if it hasn't been cleaned yet, grab a new gasket set for it if it's leaking or just grab an new one or upgraded one from the web if it's too far gone. My HS50's fuel line inlet screw dethreaded and I had to put a different carb on it, luckily had one on hand. Make sure the fuel is clean coming from the tank, could be pissing out a ton of rust thus suffocating the carb as well. Good luck, looks great!

If it's saveable, you should vinegar treat that tank. Then wax er up with something see how it cleans up. Use an inline filter of course.

Thanks... the tank was actually in surprisingly good condition, and the fuel runs clean. I'm thinking I'm just gonna replace the carb but I will try cleaning it up 1st. Thanks for the compliment on its looks... eventually the rest of the showing red will be black and I'm toying with the idea of getting a Batman decal for the tank... cause Batman. Loving all the love here folks!!!

Re: 77 Batavus restore -Newbie!

So I opened up the Carb... missing the rubber seal completely and the set screw that tightens the clamp was loose before I even got to it. The carb itself was pristine... like I could eat off it clean (aside from the fuel, lol). Checked, everything moves beautifully. I almost think the carb was cleaned and then the previous owner lost the seal and wondered why it stopped running. Once I get a seal I bet anything she will run like a champ! I'll update. Thanks everyone for steering me to the carb!!

Re: 77 Batavus restore -Newbie!

Got the carb sealed up with a new rubber band. Got the engine to run for 10 seconds! I think now it's a matter of time and rolling it down my big hill over and over lol. I ran out of time today but oh tomorrow! Sorry about the posting often, I'm a bit excited. It's my first time after all ;-)

You're doing fine . ;)

You might need to replace the engine seals. They are probably 40 years old and leaking.

How do I clean the points on my Batavus starflight moped

Re: 77 Batavus restore points cleaning

It's all in Fred's Guide :-) I cant reccomend it enough. Theres a free link somewhere here, just not sure how to post said link in a comment yet

Re: 77 Batavus restore -Newbie!

It's funny how you say you want a Batman decal....batavus sold and almost identical model called the mobat that had bat decals.

Re: 77 Batavus restore -Newbie!

Yeah, take a look here Its a great resource. Things are a little different from bike to bike but the process is pretty much the same. I highly suggest buying a 12.12 dellorto or a 13.13. The encarwi can be a bit of a pain.

Re: 77 Batavus restore -Newbie!

Yeah, I knew that :-) Its what gave me the idea lol

run Marvel Mystery Oil in your tank for a few it will swell the old seals and give you a season

Hey just from that pic I can see you're running really rich you're not supposed to be blowing white smoke like that

Re: 77 Batavus restore -Newbie!

This is mine. I restore mopeds as a hobby

Re: 77 Batavus restore -Newbie!

Really wanna do a Moby swap on one of these....

Re: 77 Batavus restore -Newbie!

♣Slew Foot♣ /

A Peugeot 103 engine would be nice but I just got adapter plates 14 Puch 1/4 a Tomas engine one of these days when I have a Fab shop I'll take a cutting torch to him and make the plates fit the batavus brackets so that you don't molest the frame and you have all the convenience of being able to buy parts that they still make

Re: 77 Batavus restore -Newbie!

Alexandro Ramirez-Nagy /

I wanna do a variated Batavus too, I think a Moby would look better on one. But it seems pretty unlikely that someone will do it

Re: 77 Batavus restore -Newbie!

Oooph that's gorgeous

Re: 77 Batavus restore -Newbie!

That was 18+ years of yuck blowing out. She runs clear and sweet now :-) Thanks!!!
