125H Clutch, carburettor & gearing?
Posted: 21 Sep 2015 13:07
Gentlemen,
Purchased a 125H in 2006 that then 'sat' until earlier this year. 23,000Km on the clock and doesn't appear to have been thrashed or dropped, so far!
I've had the forks chromed by HCP, paint attacked on tank and mudguards by 'metal worm', so refinished with 2 pack and red stripes applied as paint rather than tape. Rear shocks devoid of damping , so a pair of NJB shocks installed. The exhaust pipe is still sound, but the chrome is rubbish. The silencer has been emptied of all the loose bits patched and then painted with VHT black exhaust paint. The wee hole at the front end prevented drainage of the condensation. New Hidenau tyres and tubes, the old ones had plenty of tread but were cracked and perishing in the tread.
Carburettor rebuilt with new float needle, choke plunger, 'O' rings & gaskets (Eurocarb). The main jet was changed from the 82 that was installed, to the 72 listed in the 'blue' manual as "standard". Unable to check plug colour until after MoT, so will take it for a run afore checking the colour.
Slipping clutch even after cleaning and de-glazing all working surfaces, so purchased (NLM) new half friction and 5 full friction plates. "Thank you!" to Paul Compton for the kickstart installation video on UTube, it was driving me crackers! Still occaisionaly get a 'skirling noise when sitting in neutral and ticking over from the clutch area? Have I missed something when tightening up the clutch spring retaining nuts? Done up 'tight' at present and of 33.15mm average spring length. Plain metal plates 1.8mm thickness. Oil was the familiar oxtail soup colour, so the breather has been extended to the rear mudguard and the 2 baffles removed from the engine end of the breather pipe, the condensation just runs straight back all over the gears, kickstart then into the sump. Not nice. Changed the oil twice so far.
Passed the MoT today, but after riding an SRX 600 single or a Ducati 450, the top speed of 60Kph and lack of any real 'get up and go' was disappointing. Yes, I know it is a 125, but, the motor feels strong even though 'tick over' is vague, it pulls cleanly, and yet it is almost as though the clutch still slips or the gearing is way "off"! I was expecting cruising speed of ~80Kph.
I realise there are not many of these about and experience/knowledge is lacking, so any ownership experience would be gratefully recieved.
Thank you for your time.
My regards, Bill
