They run on smoke. If you let it out, they stop working.

Only cars that contain British words like "boot", "bonnet" and, my favorite British insult, "dipswitch", can have positive earth.

Shocking! There's "American" so I thought there'd be "British", too. Because in American we write "By" the way, and in British, it's obviously "Bye" the way. Ever heard anybody speak Alabamese or Yorksish? Next you'll be telling me that those aren't real languages either! And for "Earth" we use the REAL word...."ground" And it's ALWAYS negative.

Air forks and swingarm gussets with forward shock mounting were period modifications...mostly on MXers. Never saw an air fork with quite that much plumbing, though. We usually just put a schrader valve in each cap. On a trials bike, they're probably better for letting air out than for putting it in! Nice work on the skid plate. The paint on the blue one looks like a bultaco flat-tracker. Wait a second.... 23" front?!

I find that the biggest problem with hydraulic clutches is right at the adjuster on the lever. Many folks screw the adjuster in to get more disengagement. This may work with a cable clutch (but still beats the throwout parts), but not hydraulic. They must be adjusted so there is a tiny bit of slop between the adjuster and the piston.

Cope.... I love it when you speak British

Could be coil, too. When they go tits-up, they generally work until they get warm and cut out. I suppose you could run it until it quits, then take a reading between the LT and HT terminals.

Shift up a gear!

Could be running out of fuel under heavy load. Check the float level and the fuel tank and float bowl vents.

I think Boyesen still has the patent on the dual-stage reed. Work on top and bottom. Always loved their product.

Is your plug a nice light, toasty brown?

god turds?

I only ever used motor oil in mine and never had a problem. It was cheap enough that I felt fine about changing it every couple rides. Although I'm a little out of it...there used to be stories of clutch plates becoming un-bonded and it was almost invariably when running ATF,

You must ride FAST!! Anybody I've ever ridden with has gotten a couple hours out of a tank.

You could try adding length to the intake tract. A bit of radiator hose will do the trick. My son had one of these and a lack of bottom end was definitely noticeable. I wonder if a flywheel weight is available...

I'd rather have to prep an electric bike to run in water up to the seat than a gas one!

I wouldn't bet on it...electric motors are relatively inexpensive, plentiful and easy to adapt to various applications. A motorcycle company would probably not have to develop a proprietary engine...or batteries for that matter. Maybe the money is in a conversion kit. Buy a trials bike with a clapped out engine and convert to electric....

What he said.

I wonder if unsprung weight is as deadly to a trials bike as it is to other competition bikes.

The skate park stuff is a little "who cares?", but this bike looks like it delivers the goods in the sections...

Wow! Thanks for posting that, Martin! I have to admit to giving a little gasp when Bernie popped on screen. Like the ghost of a long gone hero.

You're my freakin' HERO!!!

Pump? There's a fuel pump on these now? Are they injected? I've been out of the loop...so to speak. You'll be really pleased with trials bikes if you're an MXer. No re-bores, no new clutches, no trick bits needed to stay competitive. They're ready for world round competition right out of the box. You might need a chain once a season if you ride a lot. One o-ring chain lasts me for years. Have fun!!

No love here for the old flame wrench? Get it good and hot and it'll probably drop off.

Spend the extra sheckels and get the best late-model bike you can. I've been around them all...and I'm the guy with all the tools and the lift in my garage...so I fixed all the local bikes. For my money, Sherco is the most sorted-out bike. Montesa has the tastiest bits, but they're expensive to replace. Scorpa is just flat-out sexy. So is Beta... Both of those will keep you away from rebuilding dog bones. Gas Gas seems to be the lightest and quickest, but light can equal fragile. Heck...they're ALL good. The best thing you can probably do is buy whatever brand has the best support for parts and service near you.
