[dan237]

hi could somone help me Iv just got an rg 125 f 1993 to get the bike to start I need to put a little bit of fule in carb by removing the air fillter the bike will fire up and rev ok and I put the air filter bk on when riding it will go a long but the rev will not go above 700 ? this what no about the bike it has aprilia rs 125 carb fitted and was like this when I got it and the power valve is allways open. would this all be down to the carb ?

With the power valve always open your sacrificing power in lower revs.

I had the same issue with my rg when the previous owner put the power valve cables on backwards.

Try it with the power valve closed.

Although im not sure if that is why you are having to poor fuel into the carb.

Hi

I would suspect that the carb hasn't been set up to work with the RG.

While it is probably possible to get the RS carb to work on it, it is probably easier to just get an original carb and fit that.

All the best

Hi Ben, Did all the RG125F's have a TM32 like the RGV VJ21?
I thought that uk ones or some of them had a TM30SS which is a very rare carb to find secondhand indeed.

The reason I ask is that I was after one for my KMX125, but I could not find one for looking, so I had to buy a brand new TMX30 instead.
