Taming Suzuki’s

Came across this test in a DIRT BIKE to tame the 71 – 72 TM400 Cyclone I have heard of other using the TS400 ignition but I have not found any written on that yet. Not sure if the 74 needed the same treatment as the 75 was said to be ok but by then the RM series out and that was the end of the TM’s.

A BOLT-ON for TM400 sweaty palms?

people have this fear of snakes. Others inwardly when they themselves alone in a dark Yet others can’t stand up high, or even worse-flying in an

All of these fears pale by to the fear-inducing potential of a stock 400 MXer. This is one of the truly Machines Of All Time.

What it increase your pueker Part of the problem lies the frame. another part the suspension—but the bulk of the guilt with the power band of the

There is no such thing as a little more” from the grip on the TM 400. Nosirree. You get a giant handful or the engine This phenomenon is, of course. by the lack of flywheel weight.

A cure, then, would be to on some weight to slow the rev down to a more usable Remember, power that not get to the ground is wasted power. And building revs mean the bike will be easier to

At least in theory.

And that’s why BIKE decided to test of the bolt-on flywheels currently on the Woodland Hills SportCycle the bikes and the equipment for our controlled Along with our intended of the 400, a flywheel was also on the 250 MX.

Even though this doesn`t have the jolly of the larger machine, Woodland SportCycle claimed that it the 250 into an easy to-ride

The bikes were ridden in trim first, to get the feel of the If you read the test in the October “72 BIKE, you’ll remember we were favorably impressed the power band of the 250, so we couldn’t see why SportCycle offered wheels for this bike. reasoning was that some might want to take the 250 riding or something of that

They claimed that the ol their flywheels would the rider to bog the engine down to low r’s. Would we test the 250 Sure. Why not?

Our other was a brand-new, totally stock 400 MX. For this machine, we had two separate to try. A 2-pounder and a 4·pounder. We the heavier item.

Off to the trails the DIRT BIKE Wrecking with two Suzukis in tow. as previously stated, were ridden stock. The 250 was as we remembered power and very rideable. It be ridden at very low revs for a machine low gear would let the move forward at a walking with the clutch out, above idle.

Any slower than this and it was to slip the clutch to keep the from stalling.

A 2-pound was then bolted on the 250 (after a back to the shop). The 250 will not the 4-pounder—2 is the maximum.

An immediate was felt in the engine performance Not all of it desirable. While the engine lug down lower and smoother, response was sluggish. Not only did it too long for the revs to build, but it took a great deal of for the engine to return to idle the throttle was shut off.

like a trials machine.

One factor made itself The rear brake was less and had difficulty slowing the bike This will always be the where heavy flywheels are against brake shoe In the case of the 250 Suzuki, however, it had a giant reserve of brakes for so this cannot come the category of a Good Thing. No

A rider who installs a heavier on the 250 will find his lap times on the course getting slower. For riding? Even though we it makes the engine more the undesirable side effect on the brake makes us hesitate to its use on the 250.

Unless the rider the rear brake to be more

Our attention turned to the 400. a ride on the bike in standard Culp. The merest tweak on the produced a spinning rear Or if there was a modicum of traction the front end would leap for the cloud.

If contact was made a series of harsh bumps, the would slither and hop sideways in an Coming out of a corner under power was a true adventure,

Back to the shop and zip-bam-boom—there we with a heavy wheel on. This one a 4 pounder. Back to the area, and a pleasant surprise. 4—pound slab of steel did things for the 400 racer. No kidding.

Without taking a single away from the top end of the Cyclone, it the power band almost Additionally, much of thc tendency for the wheel to lock up under was eliminated. Unlike the 250, the 400 had an sensitive rear brake.

is the best thing, the single thing a rider could do to a stock 400 Suzuki. In Fact, really ought to he a law requiring the of the 4-pound wheel before the can be sold.

Much of the sideways hop and the machine is infinitely more The bad handling is still there, but this is helped considerably of the more predictable throttle One can almost trail ride the not quite.

We would recommend the rider go for the 4-pound flywheel than the 2 on the 400.
