Not familiar with the set-up of a Puch clutch but when confronted with a no replacement available situation I was able to locate friction plates that fit my Batavus and then drilled out the old rivets on the plate, refit the new material, and attached it with tiny flathead machine nuts and bolts. Several hundred miles on this set-up w/o problem. Had I not found the friction plate, was prepared t

JB and marine-tex are both excellent within their range. The larger the area being replaced the harder the job in terms of the glue holding up. They do best on cracks, small gaps and minor chips. If you are dealing with something like a fingernail sized chip, you may be better to have a skilled weld shop build up the area with weld passes and then you grind it down with a dremel tool if you'

Performance exhaust pipes are not a simple bolt-on so far as I can tell. Each is modeled to a variety of engine specific measures. In short, if the pipe is not designed with your motor in mind, you may be taking an expensive chance on improved performance. If anyone knows of a near universal pipe, please report it.

Good tip Chris. Never understood the diff. in the two products. Thanks.

Chris describes a very fancy nut, worth a close look. Regardless, I use antiseize thread compound on almost all old threaded connections, have restored several cross threaded connections this way and it makes all enventual removal situations better. If it is cross threaded( a magnifying glass helps see this) use generous antiseize, turn the nut till it sticks, then back off and go a half turn at

Tonight I happened to be inside my front wheel to check an unrelated issue and found the bearings to be bone dry. They are supposed to be grease packed on my Batavus. The fix will not be that bad but had I been on a long trip it could have spelled disaster. Advise that if your bike is an early model, you pay close attention to these basic maintenance issues. I will next check the rear. Suspect

You have a challenge here. On the photo's I found your bike had a simple short pipe with no inherent performance issues. You might try making an accurate measure of the distance between the centers of the studs where they leave the cylinder as well as the inner diameter of the exit hole from the cylinder and contacting the italian co.'s you mentioned to see if they can offer a semi sto

The tuning tips are great. My bet is on the jet size. Had the same symptom and a two step smaller jet cleared it up. The other items are certainly worth checking.

I got jets for my old Bing-Encarwi by searching the web. Try :Bing International L.L.C.1704 South 525 Road, Council Grove, KS 66846Orders - Toll free 1-800-309-2464Tech 620-767-7844I had to subsequently write to their German site to get the parts sent here but after a week or two of effort it worked out well.

A used cover would probably be less than a professional weld job though a full service shop could weld aluminum. I had excellent luck with JB Weld (an epoxy) on a cracked tranny case in my truck. The critical part was to use degreaser and let it dry before gluing.

Glad this high rpm angle came up as that is the only time I've experienced what I call 4-stroking, a burrble sound and mild loss of power at full throttle. Running w/o an air cleaner actually made it worse. The manual from my bike says to expect this after a lot of miles and put in a two step smaller jet. I went from a #56 jet to a #54 and it all but eliminated it.

It is probably unreliable from here on. The "inside" and "no concrete" comments are dead on from my experience. Unless you are obsessive enough to recharge once a month with a standard 1 amp. charger. purchase of a self monitoring charger for motorcycle batteries ,with 6 volt charge option, is worth it (still must be in from severe cold). The option is to to buy a new batter

I'd like to. If not this weekend, next. Am about 3 hr. south. Understand these are pure projects.
Ned Renner — 20 years ago
I'd be overwhelmed. Will patiently await the outcome. With the Batavus near completion it may be time for another project. Of course some friends say there are quite a few projects in the garage right now. Great find and a good save. Many a machine has gone to the junk yard when relatives have come to clear out a failing property.

fred's guide is a good general start. Invest in a set of small feeler guages, Sears has a great combo feeler/spark gap set. A continuity light is also cheap and very handy. A manual for the actual settings is almost vital though fred's ballpark figures will probably get it running. On some bikes there are timing marks on the flywheel and housing(hope for this), on others you have to

Great tip. thanks

http://www.menintools.com/derbi.html This is the east coast distributor. There is some history and info at the site. At least this could yeild a parts source if needed.

I did a google search and it took me to a 2001 post at Moped Forum with several responses from people who had done some modifications. You can also look here http://www.50cc.nl/

Well done indeed. I seem to have become Batavus oriented since my son hauled one out of a neighbor's garage last summer. Let me know if any lurk in the pile. Where do you find space for this venture?
Ned Renner — 20 years ago
Have found several supply sources of new old stock parts for carb.s. and general upkeep. Takes 30 days plus to get them, but this appears to be a strong (last) source. Contact as needed. 01/03 is the date if you are searching a historical file.

I've found a lead on software for designing pipes. Doubt the guy will give me the info, he sells pipes in Europe, but if so it would make expansion chambers a reality for most applications. Will report if it works out.

I'm following B. Lamborn's project with the Tomos pipe. He is not too specific about what it has done for performance. He may have done a number of things at once and the thus its hard to tell what the pipe gained. I hope to find pipe in use on another application, like racing karts, that can be retrofitted. Pipes come in many shapes that have varying effects on the power curve. If

Any ideas on a universal fit expansion chamber exhaust pipes for road use with mopeds produced before such pipes were custom made for late model bikes?

Any leads on a #54 jet for my Encarwi-Bing H12 carb as fitted to a '78-'80 Batavus Regency VA II.Moped Warehouse has proven again and again to be of little use. Two inquiries have gone unresponded to. If Chris says it's in the mail, it might be, but then agian it might not.

http://www.mopedworld.com/MopedScooterParts.htmThis link lists your make of bike and is a parts source. You might also try ebay for a parts bike as it sounds like you will spend alot to replace everything with new parts.

A classic approach to grounding problems is to get it running at night then spray the engine area with a misting bottle of water. Shorts tend to show up as a spark show.
Ned Renner — 20 years ago
Check the availability of parts before you start. If you are willing to figure out how to check the compression ( do that first) , do timing and rebuild the carb you are ready to go into it. If it hasn't run in years, it will need rehab., patience and parts to be safe and up to speed. A good project depending on personality and skill.

I built up one for my kid at modest price (no expansion pipe) and it dusted all mopeds that showed at a local track. It's a lot more to handle at speed, but they are a kick. I like em.

Soak it repeatedly in WD 40. Smash the old bulb. Grip the inner metal liner with thin needle nose pliers and twist it out. The nubs on the bulb are important and if you don't look at a new removable bulb from a car brake light you may not realize what you are dealing with. Remove a good one and look at how it works. If you have already destroyed the old socket, research how to wire in a

Write the manufacturer and use the bike serial # to get the key code and a blank of the key.Take it to a "good" locksmith and get a key made. If the shop acts like it's a problem, say thanks and find a more experienced shop.
