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.

what should I do about the shifters I have already tried to de gum them and they just wont budge beyond "3" on the right side and beyond "2" on the left!

So I'm stoked at just before 2am I managed to get the left working on all three gears on the chainring !!! Took apart the rapid fire shifters gave them a clean out put some rp7 on them works sweet as

I dunno - but it's a 98 MY Topanga - what else is there to know?

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.
