Hi and welcome

There is no problem at TDC you can point it up or down, as long as everything else is correct.

the thing is that i bought a second hand engine and it is extremely hard to e-start it when cold,i have everything correct,do you think it this bike only starts kicking it when cold?

Hi

I don't think that it's extremely hard in cold, I just don't do it because I love my sprage

Does the bike starts easy with e-start when hot ?

Is you bat ok ? most of the times the bat goes down a bit when the bike is stop and if it runs just a bit the charge goes back fast to the normal charge.

Re: lobes up?

Hi

I would tell you to check the ignition timing, but if it was a older bike, on those you can't miss it, so it should not be that.
In that engine you could have a cam timing problem, you don't know if it was opened before and by who ? so it can have all kind of strange things done, you should check.
Also if it's always difficult to turn the engine, you can have a bad spring on the auto decomp.

If it was me I would open the clutch cover and the rocker cover and check things before start using that engine.

Re: lobes up?

sounds like the tappets are tight?

generally the auto decomp spring is weak and the engine and your foot can't deal with the full compression.

Re: lobes up?

thanks Taffy,it actually sounds like that,maybe needs a stronger decompressor spring so the valve opens every rockerarm turn to release compression and let it start,cheers
