https://davidarmstrong.smugmug.com/Enfield-reduction/i-swGCrjk I built one up, it needs a better ignition and a slimmed down primary but I am pleased with how it rides. Hit and miss on parts from India. Just at 300lbs with oil and gas.

4 speed Bultaco's are great to mix and match parts. I built a 1966 Sherpa Scrambler with a Matador top end and a Mercurio close ratio gear box lower end. http://bultacoforum.com/index.php?topic=267.0 https://davidarmstrong.smugmug.com/My-First-Gallery/ I also ran a 1966 Matador 4 speed set up as a trials bike for about 7 years, only recently selling both the Sherpa s and trials bike to the same young guy.

None as far as I know, the difference is in the primary gearing. These make great trials motorcycles with very few changes.

Dave my Enfield heavyweight trials isn't the problem, it my G80cs scrambler for Sundays races that is screwed up. The big bike needs a new carb and the head steady is stripped out and its blowing bubbles at the base gasket. Dave

Yep, thats Jody's AJS 350cc. I didn't drive down because my own g80cs has a few Gremlins that need to be sorted. I should have just brought out my Enfield but that's a long way to go and only run one event. 6 hours one way from Redmond WA. Man I am catching **** from the VME member for not going!

Hey Swooshdave, I like it! If you get a chance check out Jody Heintzmans 350 AJS for inspiration. Also the VME Vashon Island guys are big on the Matchless/ AJS stuff. I have a G80cs that's giving me fits. Its hard to resist the big bikes from o'l Blighty. Dave Armstrong

I would start with a rod kit-crank shaft rebuild and work out from there. double check the ignition side where the crank bearing fits for wear. The last 4 Bultaco's I had rebuilt had bad ignition side bearing surfaces. I don't think Bultaco compensated for heat expansion and the left side bearing moved on the crank causing wear.

With my E250 I can crawl in between my Matchless and Enfield and still have room for the dog. when the wife goes i drag a 5000 pound travel trailer no problem. The big Fords get stuck on slippy surfaces, my Chevy vans never had such problems. something to do with fueling injection I suspect.

Loose flywheel?

Tyre=pommy. Tire=Bubba.

The bash plate i built for my heavyweight Enfield is cracking and dented. It as made of 3/16 inch aluminum with welded "wings". I need something heavier duty. what is the recommended aluminum? Should I switch to steel? Dave

Sammy Miller and Ralph Venables are big names in the sport. A spec tire seems so obvious to me.

https://davidarmstrong.smugmug.com/Campera/i-WMKvpHK Rode this in a few trials before getting my Matador. Cheng Shin tires fitted.

All the talk about period correct Pre 65 trias motorcycles and I havent seen any mention of modern tires. My guess is if a specification tire such as a Chang Shin C186 was mandated then the sport would be much closer to the magic pre 65 than by limiting any other modification? Maybe this has been discussed already?

Stock Enfield front end. Brake backing plate slots into boss on fork leg.

350cc. stock Enfield stuff as much as possible.

These pics are from a show today in Renton WA put on by race premotor Siege. Some neat stuff including my well recieved Enfield. Sorry for the shakey pics. https://davidarmstrong.smugmug.com/CJ-show/

You guys are funny. Obviously wheels can be built cheaper. I only wanted to point out an Indian built Enfield could be a less expensive alternative. My wheel build included new stainless rims, spokes, powder coated hubs, bearings, brakes, newly machined brake hub (for changeable sprockets) rear sprocket, new tires, tubes, rim locks and also included a modified swinging arm for more clearance. I had hired out all the work because I got more money then time at this point in my life. I paid $700 for a running Enfield with less then 500 miles on it and bought many other parts straight from India. Dave

My Enfield built on the cheap. Wheels cost the most with about $1500 into them. Around $3000 total at this point. https://davidarmstrong.smugmug.com/Enfield-reduction/i-tL3nNHs https://davidarmstrong.smugmug.com/Plastered-Purple-Penguin-Trial/

In the USA the Indian built 4 speed Enfield Bullet is considered a replica and eligible for AHRMA Premier class (Pre-65). Parts are incredibly inexpensive for the 350cc bullet. As an example I bought an aluminum cylinder, piston assembly and gaskets for under $150 straight from India.

Hey Mike, Femsa ignition is bullet proof. That little M21 did over 6000 miles on the same plug and points. Where is my article? Get cracking!

Loose flywheel?

If they were rubber you should have left them alone. Now you have to machine some bushings and stuff to put it back together again. The rubber never goes bad. Sorry.

Sorry, the cases have to be split to install the spring correctly. I have replaced them without splitting the cases but it was in desperation and I had to force the spring into submission with a big pair of pliers. Dave
