Ive just bought a MC18 with a MC21 SP Engine and apparently race tune ECU? Unfortunatley this is my first 2 stroke and i dont know whats normal and whats not ..
My Qs n probs are:
Hard starting -- if its been started once that day it will start almost first kick every time, but the first start is a B@!CH 25-30 kicks give up, come back try again till eventually she just cracks into life. Ive replaced the fuel lines from the tank and the inline filter as it was clogged with oil ( get to that later) also the filter was positioned horizontally and now where near filling so ive positioned it vertiaclly to assist with gravity feed.
Then ive cleaned the carbs (float bowls had some crusty crap) float needles seemed good but gave them a squirt. ALso performed a compression test and got about 110psi on each from cold.
I had also replaced the spark plugs the day before and found they are oil foiled already?
When i bought the bike, the guy said he always puts a splash of oil in the tank and i should do the same - my concern is 2 things
1) I think the extra oil is the starting problem as its fouling the plugs?
2) the oil in the reservoir is being used, but its dirty - ive topped it up twice already so i know what im putting in is good but if its only drawing what it needs why would it be getting dirty? - is this the reason why hes telling to make sure i put some in the tank?
Other smaller issues - the back break switch doewsnt have a spring on it so isnt working and i can only find a spring for a MC21 will this fit?
The Neutral light doesnt work - the wire from the gearbox loops around and goes back into the gearbox? -- i know its an MC21 engine but surely i should still be able to get the Neutral light to work with the MC18 dash? If the switch is the problem can i get a new one?
WOW!!! sorry for such a long whingy first post
Pics coming soon
Cheers
