Hi, I have just put a new top end in my Cagiva WMX 250. I replaced the small end bearings, piston etc.
I also put a new spark plug in, new tranny oil, new air filter, carburettor jets, and upon trying to first start it it would not.
It sounds like its nearly going but just dont, also its a bitch to kick over now since I put the new engine in but i put this down to the increase in compression.
I have had it start a couple of times and as soon as i let go of the throttel it dies. Then when I start kicking it over again it wont start.
PS Have tried a different spark plug aswell.
Did not think that idle settings could be adjusted untill warmed up????? has this got anything to do with it????
Have tried cleaning the plug etc, which has helped but does not long term.
There is fuel getting to the engine, as the spark plug is wet (A sign of rich running I read?), and the spark plug is sparking as I held it up to the engine casing.
I moved the needle clip position, up one to lean it but it started for about a second then died and wont start again.
Please help.
Also when I pull the spark plug out it is a little dirty, which I think could be a very little bit of dust from the pipe, which needs running through.
Any help greatly appreciated.
After lunch today I am not on the net till tuesday, and would likle to get the bike running over the weekend so quick replys appreciated.
PS I forgot to say after eliminating nearly everything, spark, fuel etc, I though it could be the reeds, they were old but not that worn, but dirty! So I replaced with the boyeseen dual stage reeds I had which i wernt gonna put on untill a ran the engine in.
This did not make a differenece.
Also when it does kick over, sometimes it backfires, so bloody powerfull that the pipe comes off the manifold.
