Hello again. I know the choke on a cold engine causes higher rpm but mine revs so high when the choke is on I worry its ruining the engine. When the choke is then switched off the revs are fine. It certainly isn't healthy for a cold engine to rev that high. Carb is a dellorto. All the inlet rubbers are new so i don't think its an air leak. Could the choke itself be worn causing this high revving. Carb has been stripped-down and rebuilt. Any ideas ?

Hi Jason. I've got the right bolts too. What type of Allen key have you got ? It is a worse angle than our 250's use to be.

I found it a struggle many years back when I had a Rev 3 250 to screw and unscrew the right hand exhaust bolt. But on the 125 it's even tighter. My long reach t handle allen bars cant do the job. Normal allen keys cant get near it. Ive resorted to fiitting a hexagon headed nut and using a reverse spanner to tighten it up but it takes ages as you only have about 30 degrees rotation of the spanner. Would a ball headed allen key fit an allen bolt on the right exhaust bolt ?

Just used the JB Weld.Amazing stuff. Took a day to go off properly as it has been so cold. . Looks good after sanding. many thanks.

The swing arm is at a engineers as we speak. Will update you on its progress

Just ordered some. Thanks

Thanks for that

Thanks to all of your thoughts. Some good ideas. Definately going down the epoxy route. Seems a lot safer. Gareth

Thanks for that info. Totally agree with you regarding the welding. If it were a

I wish i had spotted it when i bought the bike but i didn't. There is about an inch square missing from the bottom outer edge of my right hand crankcase where the flywheel cover meets the crankcase. Bike is an 04 125 Beta. What would people recommend to fix it ? Could the case be welded in situ or would the case have to be split and then welded ? Anybody had any success with chemical metal type materials ? Any ideas would be most appreciated. Gareth

Ive got an 04 125 Beta Rev. Was just wondering whether other rev / techno / evo crankcase's would fit my bike. My right hand side one by the flywheel has taken a bashing and may need replacing / welding. IM hoping due to the age of the bike i may be able to pick up a used one. Does the 125 have the same cases as the 250 ?

Yes it is that carb.

Couldn't agree more. I wouldn't be surprised if i have to adjust the air screw once the system is vented rather than closed. Is it still 2 1\2 turns out approx on these little 125's ?

Just stripping down my 05 rev3 125 after buying it. Its the turn of the carb now. Intrigued as to why the two carb breathing pipes are linked together onto each other. Firstly are these breather or overflow pipes ? Secondly should they be linked or independent?

Thanks for that. The swingsrm end of the shock is seized in the swing arm so i should still be able to get the spring off then

Tried the air impact gun and still nothing. I think its going to have to be drilled out and pressed out. Definitely an engineering job. May leave it a while as the bearing is fine and i cant see me having the bike for too long. Just annoying as poor maintenance by the previous owners have caused this.

Update. Heated nut up to cherry red and the damn thing still won't shift. I've got a horrible feeling the whole bolt is seized in both the steel collar of the shock as well as the nut. The guys in the workshop are going to try an air impact type tool next.

Just been looking at the shock. If you spin off the adjusters they would then have to pass over the larger body of the shock. How do you get this bit off ?

Tried it. No joy. Will try heat tommorow. Thanks for the suggestion anyway.

You cant shock the nut by doing that as the nut is not fixed to the swing arm. If the back of the nut was against the swingarm you could.

Thanks for that

Thanks for that

I agree it needs shock but it may be difficult to do. The nut at the back of the bolt is not pressed up against the direction of force if you shock the bolt.

Thanks for that. I will let it soak over night. Just tried it again. This time I put the allen key itself in the vice and tried to rotate the swing arm. It is so seized I snapped the damn allen key. Patience is needed.
