I ride a 2015 GG 250 racing and tried a friends Vertigo 300, handling and suspension matched my bike, maybe a bit firmer and stable, nothing weird. Although it was a 300 the off idle response wasn't abrupt or snappy (it's got additional flywheel weight) it picked up revs quickly past 1/4 throttle but only as expected with a bigger engine. The fueling was faultless too.
I used a long 12mm bolt with the hex sides shaved down to fit. Grip the bolt in a vice, turn the caliper around it, or use 2 nuts as lock nuts on the bolt threads and use a spanner.
Fitted one to Beta 200, made it very sleepy to respond al low revs which meant I had to slip the clutch to climb rocks, worse than standard. But if you don't use above 1/4 throttle on eady courses it was fine. All my 250's have had one and suit me, the 200 wss the only one I've removed. Youre only adding/changing inertia, not power.
Whether it's considered the champs or the clowns bike, buy the one you really want and to hell with the consequences. Buying with the heart, not the head, is usually impractical but for me gives more satisfaction. Mick Jagger obviously bought with the head.
Found I used the clutch on decelerating to reduce unwanted engine braking. I never got the hang of riding one uphill on compact clay/mud as I do with a 2stroke.
I had 2 pairs of Sidis, nice boot, no problems, not cheap. I now have Forma Boulders, 2 years, no problems, cheapish, they're also a bit longer up the leg helping avoid footpeg bites.
Try this. Put bike on a stand, remove reservoir cap, top up fluid, open caliper bleed valve, make a cup of tea, have a biscuit or two, have another cup of tea, ponder lifes cruel disillusionments, take a cup of tea to your bike and see if fluid is dribbling from the bleed valve. If not, repeat above till it does, then have a cup of tea to celebrate.
Yes turbo, I suffer Tuesdayitis too. Monday's are no problem. Also occasionally after a trial I get a headache, I've tried drinking plenty, bar position, different helmets without success.The Tuesdsyitis and headaches used to happen after enduros 20 years back too. I wonder if the headaches are from exhaust fumes.
I agree with stpauls. I don't suffer with a chest condition, yet. There's no problem switching the engine off in a big queue then starting it again when 2nd/3rd from the front.
All valid points. I've owned many makes of trials bikes, they've all had good and bad design. My hope is one day they'll take all the good designs to build perfection. Anyone care to mention one, prepare to be shot down in flames.
As 2stroke4stroke said, i dont know of conversions, but the Sherco 200 (160) i had was a favourite I wish i'd kept. It didn't have enough power to spin up, ideal for slippy conditions at my level.
If the ignition circuit is giving a good blue spark, try the carb again, petrol on, lean the bike over till petrol comes out the overflow, choke on and kick. If no petrol overflows, fix that bit. If it does, after kicking see if plug is wet. If it is, could be ignition, these can give intermittent faults.
Reminder,don't ignore this.
