Major Problem And Colonel Angry!

Well, after a week of riding the new sherco, and my son got a brand new oset 16 for his 4th birthday, we came home from a days riding to do a once over.

Lil'uns bike seemed to have no movement on the rear,

It seems oset dont use bearings on the swingarm, and also dont use grease!!

So that was an easy fix. Cleaned up, on charge ready for next ride.

However, when i came to my sherco, different matter.

Typical of these bikes, there was plenty of play in the rear, 10-15cms of movement up and down, big play in the dog bones.

So i started stripping (the bike. NOT me!)

Heres where the headaches start!

I removed the plastics, exhaust and then upper shock mount bolt.

Then removed the lower mounting to swingarm. Very rusty bolts.

After removing the rubber/plastic frame plugs, i started undoing the swingarm pivot bolt nut, to find ONE thread holding it. I tapped the pivot bolt out and found the bolt itself had either been installed by a ham fisted retard, or had been left loose, as one side of the bolt for 2/3 of its length is now worn flat, threads included, nut wont actually grip!

Discarded, time for new!

So i remove the swingarm, and start to take off the dogbones.

Some one has glued them all up with silicone sealant!! WTF?

After cleaning that crapola off everything (mustve thought doi g that means you dont have to give a ***** about maintenance!) i pressed out the old bearings, which were rusted solid to their inner races, then pressed out the actual races themselves. Nearly all the needle bearings were twisted in the housings, so were of no use regardless of being seized!

I cleaned up the dog bones,, sanded off the rough edges where previous people mustve thought hitting it with a hammer would fix it!

In went new ALL-BALLS RACING bearings, with plently of silkolene red race grease worked into them.

I also did the swingarm lower mount as that was fubar too!

I also needed to sort out the leak on the front pipe, as its annoying! Removed the top bolt, and the exhaust fell off. The bottom bolt has snapped in the head!

Out came the dremmel, and i flattened off the broken bolt to the face of the cylinder, then center punched the bolt. In went a carbide drill, and drilled the bolt.

Left handed tap, and tapped the hole. Lots of heat later, and a left hand M5 bolt, and out comes the broken bolt. In went a new gasket and back on with the front pipe.

Now before i refitted the swingarm, i took the time to check why my back brake didnt work properly. Oh yes theres the problem. Some knobend has trapped the brake line between the engine and swinger!! Maybe thats why the spindle was knackered!!

So i get a new line, (made one up) and thread it through swingarm.

I heat the hell out of the rear caliper, but the bleed nipple STILL snaps.

Oh well, out come the easy outs, but i find the caliper is cracked.

Fixed caliper, and replaced the bleed nipple, and refitted the new brake line.

I refit the swingarm, and shock linkages, and lovely, no movement!

Start to bleed the brake, and first push of the pedal, the master cylinder goes POP and leaks!!

Off that comes, but the bottom is seized, so i cant even fit new kit.

On goes a new master cylinder and i finally at 9:40 last night got the brake bled, chain on, plastics on, airbox back in, exhaust back on, and ready to go!

I wonder how many folk buy trials bikes and ignore any kind of basic maintenence? I mean, silicone sealant instead of greasing stuff? Hamfisted fitment of parts?

They're a unique race built bike, not a kymco chinese scooter throwaway!!

You really got to know your bike that evening.

I had a 2000 Sherco that had problems with the swing arm spindle nut periodically loosening up. I used a couple drops of lock tite BLUE to help hold it in place. Did not use red, I still wanted to be able to take it back off.

Lots of people say "I do all my own work" but really

Some of them should do none of it

Hard to believe they can be so bad at mechanical things but think they are doing it right

I think maybe they feel better after waving a wrench around their bike even if they make it worse

I got fed up with it.

Seemed that after spending another £300 on parts, and still i had problems, and i had to see sense.

It was more economical to chop it in and get a new bike, from a reputable dealer, so that i could look after the bike properly, and know it was safe and ready to ride

So ive now got a new Gasgas 300 Racing.

As we have no idea just how old and well ridden your bike was, this is of little relevance. Just about the time you get it in shape you peddle it off for a newer bike. Anyone can do that! All it takes is money!

Good luck with the Gasser, cause the longer you keep and ride it the more it will cost you. I promise!

Copey is a sherco man, always has been on tc. I have tried montesa beta gas gas scorpa and sherco over the last twelve years. Out of all of them I prefer the Gas Gas to ride and maintain based on my own experience. None of the bikes are really better or worse its just down to preference on the part of the person buying the bike.
