Thank you for the replies, its been very useful, I think the damage on the piston/cylinder was just to the side of the inlet, the Air filter was shagged and the drain pipe was missing so the air box itself had a layer or mud and ***** inside! which I'm sure didn't help.
I have been busy this week so not got much done on the 315. I have sent the shock off to Brooks Suspension to have it refurbished, so without the cylinder or shock i cant really start building the bike back up. It has given me time to look over the bike properly and start fixing a few things. Forks have been striped, cleaned and rebuilt, All new bearings for steering stem, linkage, swing arm and wheels ( they where all shagged!) and i gave the carb a good clean.
I have got a load of questions about the Montesa so i thought i'd just list them and if anyone can help me out it would be greatly appreciated! but if you can't be a***d no problem :
Cleaning the carb I have noticed that i don't seem to have standard jetting, i have 120 main, 44 slow? common jetting ? also it seems that i should have an air vent hose attached to either side of the carb but mine is missing, it looks like it connect to the air sub assembly but all the tubes are missing now =(
As the bike has been so neglected i don't trust anything so would like to flush out the old oil completely, What is the best way to do this ?
best gear box oil? i know the elf stuff is recommended but i cant get it locally and it costs a fortune, any decent alternatives?
There are two wires with bullet connectors under the tank that don't seem to be used, Any ideas what they are for ?
Thank you in advance!
