Quite the contrary. You clearly do not get it.Working on aircraft, where no corners can be cut, no detail overlooked, gives a deep understanding and appreciation for ALL machinery, large and small, simple and complex.Some of the very best mechanics I know got their start with airplanes. Today they work on antique cars, mopeds, motorcycles, power equipment, you name it. And they bring a work ethi

21 years in the the United States Air Force as a master airlift/bombardment aircraft technician, in the Strategic Air Command and Air Mobility Command does indeed, qualify me as an aircraft mechanic.Or would you somehow disagree? Maybe you know better than me? It seems you think you do.

Testi Comfort with under 300 miles, has undergone major rehab to include full engine rebuild with bearings, seals, and all gaskets. New seat, repro tail light, Domino controls, all cables, pedals, carb overhaul, tank flush, new inner tubes, new clutch assembly, clutch plate, and flat return springs (in cover). Many new parts and a great deal of time in this machine. Work was done by a retired

Looks like I am all set. A pal from northern Maine saw this post and is shipping me a clutch from his stash, gratis. I had no idea he owned any Minarelli parts. I should get up there and see what else he has...

Interesting enough. I've purchased many times from Treats. A few times from Lucky Two Strokes and previously once from 1977. Every purchase was a good experience.I must be a lucky two-stroke I suppose. Thanks for the back story.

And exactly why should take your advice? I am not trying to be a smart ass, I want to give you the opportunity to qualify your statement.

Sadly while tearing down my V1 to install new bearings, seals, and gaskets, I discovered the clutch was stripped. No big deal I thought. I tapped it out to M7, snagged some M7 screws at the local Fastenal... Still no joy. Even with much heat, oil, and patience that monster was not coming off. So I cut the bastard off with my trusty Dremel tool, without so much as a smudge on the crankshaft.

Chicago GO scooter tossed the end of its crankshaft along with the flywheel and fan. Bummer. Must have been a bad crank. The break has what appears to be an old crack. The rest of it looks fine.70cc cylinder, piston, and rings were added back in the Spring. They look good too.CVT cover with kickstarter assembly, cylinder head, timing chain, long side of the crank case with final drive complete

Hey there. I've got a low (282 miles) Minarelli V1. Starter clutch sometimes works fine. Sometimes it slips and sometimes it jams. Locks right up. I've replaced the starter clutch plate. I've replaced the two leaf springs in the cover and the cable is adjusted correctly. All the parts are there according to the factory manual and the oil level is correct with fresh 30 weight, no

Just took a 1977 50V with 681 miles on it and threw some money at it. I bought a Treats CDI and Dellorto carb. I have the leftover Gurtner (which has been run through my ultrasonic carb cleaner twice) and all the Novi parts. Flywheel, stator plate, coils, points, condenser, yaddah yaddah yaddah. If you want this stuff I will send it to you for the cost of a small flat-rate USPS box. I'd h

Love that CEV headlight/speedo combo. I have the same one in chrome on my Testi.CEV built parts for a whole lotta manufacturers, you think?

How so many people could lose the battery covers and air boxes, is a complete mystery to me. Who does that?

Here is the intake on my NU50 with stock jetting. It works perfectly, is rugged, and costs less than 15 bucks. 1-inch heater hose, a couple of clamps, a piece of sheet metal cut from a can of penetrating oil, and a UNI 107 one-inch breather filter.

Hi all. Been offline for a while, up in extreme northern NH where there is no cell coverage worth mentioning.Good news. The $12.95 eBay ignition coil fixed the Urban Express right up. It's running really well. After almost 2 months of tinkering, I think it's done. I registered it for road use yesterday and am having a blast riding it.Thank you all for your assistance. I've put

I like your ignition coil. It looks like it came off my '67 Bug!

Negative. Checking them one at a time. From the white wire to ground. Then checking the blue wire to ground with a professional quality Fluke VOM. Spinning the engine with a Ryobi electric drill.With my NC50 Express, for example, I can release the spring starter and read almost 6 VAC from either the lighting or the ignition coil. Similarly, I can disconnect the alternator on my Africa Twin and

Using actual air filter foam and RTV results in a filter that can be used for years. RTV on clean, un-oiled filter foam has permanent adhesive strength.As such these filters can be washed, re-oiled and used again. The Honda filters for my SL350 have not been available for many years. There are two large foam sleeves, on for each carb. Very simple to make. The ones I made for this bike, possibl

Hey, I've disconnected the 3 wires coming off the Minarelli V1 mag. Then spinning the engine over, I am only getting 1 volt off the blue wire and the white wire. I am thinking it should be more like 6 volts, 5 anyway. You think?

Just in case you'd want to know, you can buy OEM parts from Kreidler in Germany.This past winter I fixed up an MP-19. Had no trouble ordering every single part my heart desired, brand-new, from Kreidler. I looked up all the parts I needed on their website to get the part numbers. Then I emailed my list. They sent me a proforma invoice. I paid them with PayPal and 10 days later I had a bi

Is it hard to pull the piston pin? Do they usually slide or do you need to use a puller?Most of the two stroke dirt bikes I've worked on require the use of a pin puller, just too tight to push out by hand. Unless of course the motor is hammered to pulp. Then they pretty much fall out when you take off the clips.I replaced the base gasket and head gasket on my NU50 recently. I was very surp

Type F fluid was specifically formulated to FoMoCo standards, for use in automatic transmissions in 1970s and early 1980s Ford vehicles. Here in the US you can buy a quart at Autozone for example, for $3.79 USD.

Some coils continue to work over amazing amounts of time. Some do not. My 1972 Honda SL350K2 has an original coil, one of the two anyhow is from the factory.My next door neighbor's brand-new 1975 AMC Pacer had a failed coil and a cracked distributor cap at just 49 miles on the odometer. Boy we built some quality American cars in the 1970s.Talk about parts that last? The tiny high beam in

I do not envy your workshop conditions. That's got to make everything twice as hard.I am grateful for the 750 square feet of heated, well-lit work space I have with benches, a monster vice, and many tools on acres of pegboard.The tilting motorbike work stand is especially wonderful. Anything from an Express to a Gold Wing, you roll it on and the bench tilts back to level. Probably the best

Did all of that already. Cutting off the stretched out ends of the spark plug cable. That's automatic. Replaced the spark plug cap with a new NGK (at only a few bucks each I have several kinds on hand), compression is very good.Using my spark tester, I'll show spark when it is bone cold. And it runs great. Then it stumbles and dies. Tester shows no spark at all when the coil is warm.

Hey all. I had to pull the ignition coil out of my NU50. Getting the old one out wasn't too bad but putting the new one in presented some challenges. My hands are too big, especially to reach the front screw for installation. After thinking about it for a bit I decided I could make it a lot easier.Put both screws in the new coil and then capture them by putting a small 1/8 or 3/16th o-ring

Interesting. After sitting in the cold NH air for a few hours, the spark came back. It ran great for about 10 minutes and then died. No spark.I am going to say it's a bad coil. Heats up expands shorts out.Any suggestions for coils? Will the 15 dollar orange eBay coil work? Something from Treats or Lucky 2 Strokes?

Got it now. Page 13-7 of the Honda service manual. That clears up quite a bit. Thanks. Should have this nailed down soon.
