Ok ppl so now I have big dramas with this what I thought was a bargain pickup. It seems that the front derailleur has been bent and the adjustment screws don't do anything at all :(. The left shifter will only shift between the bottom cog ie 1 and middle cog 2 , not even the 3rd one :(
At the back I can only get it to shift 5 out of the 7 gears and depending where I adjust the barrel cable adjuster its 5 gears from either top cog or the bottom cog upwards ! ARghhhh!
I have tried pulling apart the rapid fire shifters and doing a compressed air blow out and spray some RP7 in there to lube it up has not even improved how they were before .... ! HELP!

Dismantle the bike; everything. Clean, lube, re-build and replace where necessary.

I like that. It is indeed full Cromo. The Sorrento, next model down, had only a Cromo main triangle and genetic steel stays.

After cleaning out the right shifter and spraying with WD40 I have managed to get all seven gears working, mind you the old shifter cable was in bad shape so i salvaged one from a spare EZ fire shifter I had laying around.
Now it seems that I must have accidentally got some of that WD40 on my hands and subsequently on my lips. Now I have a fat lip from that :(
That will teach me to be careful next time!
All 21 speeds working, but the front Derailleur cable needs to be replaced too as I suspect its catching on something from time to time.
